To know how to thrive in the building industry as an Architect, let's try to understand what a supply chain of architecture practice is and and an Architect's role in it is. ## What is a Supply Chain? A supply chain is the sequence of processes involved in the production and distribution of a commodity. It consists of a network of entities and the bi-directional flow of materials, information and money. ## Bi-directional Flow of Materials, Money and Information The supply of architecture can only work when there is three bi-directional flows along the supply chain, material, information, financial. People pay money in exchange for information and material. Without either flow, the supply chain will not work. Knowing and understanding the various parties, products/services and flow will help us understand the opportunities for improving the efficiency of 'supplying' architecture. *Where are you in the supply chain of Architecture?* # Parties Involved Learn more about the various stakeholders in building projects.
There are several parties that are typically involved in a building project. They are listed below. ### **1) Owner**/**Developer** The person or organization that is commissioning the building and will ultimately use or occupy it. ### **2) Architect** The professional responsible for designing the building and ensuring that it meets the needs of the owner and complies with all relevant building codes and regulations. ### **3) Main contractor** The professional who is responsible for managing the construction of the building, including coordinating the work of subcontractors, ensuring that the work is completed on time and within budget, and ensuring that the building meets all safety and quality standards. ## **4) Subcontractors** Specialized contractors who are hired by the general contractor to perform specific tasks, such as electrical, plumbing, or HVAC work. ### **5) Engineers** Specialized professionals who are responsible for designing and overseeing the construction of specific systems within the building, such as the structural, mechanical, electrical and plumbing systems. ### **6) Consultants** Specialized professionals who provide specific services to the project, such as acoustical, lighting, or landscape design, wayfinding, security. ### **7) Suppliers** Companies that provide materials and equipment needed for the construction of the building. ### **8) Contract Administrator** The professional who advise the owner and the project team on legal matters, such as contract review and dispute resolution. The Architect or Quantity Surveyor can play this role. These are the most common parties involved in a building project, but depending on the size, complexity, and location of the project there can be additional parties involved. # Design Process in Practice Learn more about the design process in architecture practice
The design process for architects typically includes the following steps: 1. **Initial consultation and project briefing:** This is where the architect meets with the client to discuss their needs, budget, and desired outcomes for the project. 2. **Site analysis and research:** The architect conducts a thorough analysis of the site, including its surroundings, zoning regulations, and potential environmental impacts. 3. **Concept development:** Based on the information gathered in the previous steps, the architect develops several conceptual design ideas for the project. 4. **Design development:** The architect refines and develops one of the conceptual design ideas into a more detailed design proposal. 5. **Technical design:** The architect develops detailed technical drawings and specifications for the building, including structural, electrical, and mechanical systems. 6. **Obtaining necessary approvals and permits:** The architect works with the client and any necessary authorities to obtain the necessary approvals and permits for the project. 7. **Construction documentation and administration:** The architect prepares detailed construction documents and oversees the construction process to ensure that the building is built according to the design and specifications. 8. **Post-construction evaluation:** The architect evaluates the completed building and makes any necessary adjustments to ensure that it meets the client's needs and functions as intended. The process is non-exhaustive and may differ based on contract type and locale. Check out this video by Architect Dami Lee on the Architecture Design Process from the project brief to detailed design ready for construction. {% embed url="" %} **For more details you may refer to the following resources:** [RIBA Plan of Work 2020](https://www.architecture.com/knowledge-and-resources/resources-landing-page/riba-plan-of-work) [SIA Scope of Services Matrix](https://apex.sia.org.sg/xshare/SIA_Scope_of_Service_Matrix-20180814-for_website.pdf) # Working with Consultants Architects do not work alone; meet the team who makes building design possible
An architect typically works with a variety of external consultants throughout the design and construction process of a building project. These consultants may include structural engineers, mechanical engineers, electrical engineers, and other specialists who provide specialized expertise in areas such as acoustics, lighting, and fire protection. The architect is also responsible for coordinating the work of these consultants, **ensuring that their designs are compatible** with the overall design concept and that they meet all necessary codes and regulations. {% hint style="info" %} **Note:** Specialist design work needs to be checked by respective Qualified Person, who may or may not be the Architect. The Architect shall not be liable for any negligence on part of the Specialist. {% endhint %} *Learn more:* [Specialist Design Items](/01-industry-basics/specialist-design-items) Most importantly, the architect also acts as the primary point of contact between the consultants and the client, and is responsible for communicating the progress and any issues that arise during the project. # Working with Clients They are not just your paymaster..
Architects work with clients mainly by: 1. Understanding their needs and desires for a building project. 2. Using this information gathered to design a functional and aesthetic space that meets those requirements. 3. Providing guidance on materials, construction methods, and cost/time implications for certain design decisions. 4. Getting the necessary approvals and permits (planning permission, written permission, building plan approval, temporary occupation permit and statutory completion. 5. Overseeing the construction process and ensure that the finished product meets the client's expectations. # Working with Contractors Building your dreams and more!
The Architect shall collaborate with the Main Contractor to ensure successful execution of the building project. There are 5 keys ways to do so: 1. **Drawings and specifications**: The architect provides detailed drawings and specifications for the construction. 2. **Site inspections:** The architect conducts site visits to monitor progress and address any issues that arise. 3. **Review request for approvals, information (RFA / RFI):** The architect reviews and approves submittals such as shop drawings and material samples. The contractor should also submit request for information if he needs more clarification or to raise discrepancies in the drawings. 4. **Coordination**: The architect coordinates the work of other consultants to ensure designs are integrated. 5. **Ensure proper construction as per drawing and specifications:** The architect works closely with the main contractor to ensure the design and plans are properly executed. # Working with Project Briefs
Architects need to look out for the following in project brief from clients: 1. **Project scope and objectives**: Overall goals and objectives of the project, including the type and size of the building, the number of floors and rooms, and any specific features or amenities that are required. 2. **Site information**: Details about the location of the building, including the address, zoning regulations, and any environmental or historical considerations that may affect the design. 3. **Budget and timeline**: Established budget for the project and timeline for completion, including milestones for each phase of the project. 4. **Design requirements**: Specification of any design requirements or preferences that the client has, such as architectural style, materials, and color palette. 5. **Approval and permitting process:** Outline of the approval and permitting process that will be followed, including any relevant city or state codes and regulations. 6. **Consultants or contractors:** List the consultants or contractors that will be working on the project, including architects, engineers, and builders. 7. **Client's contact information**: Look out for the client's contact information, so that the architect can reach out with any questions or concerns throughout the project List is non-exhaustive and can be added on if there is need to have more constraints and criteria of successful design and construction of the building. # Design & Coordination Basics Architects cannot work alone
Often times, you will need to work with the project engineers across disciplines on a wide variety of design and coordination issues. Below is an overview of the many design considerations that require both architects and engineers to work out together: ## Architecture & Structure Checking for consistency with design of structural elements and external works in relation to architectural design requirements Aspects: * Structural elements - Types of walls, parapet/kerbs, floor, columns, roofs, beams, railings * Dimensions - Headroom, clear width & height, thickness, setting out, storey height, beam depth & column sizes * Openings - for doors, windows * External works - driveways, drainage, detention tank, entrance culvert, slopes, retaining walls, levels. ## Architecture & Mechanical Checking for consistency with design of fire safety provision, sanitary/sewerage, gas/water as well as ventilation provision in relation to architectural design requirements. Aspects: * Ventilation - Types of Mechanical Ventilation, Ducting layout, Air conditioning * Sanitary/Sewerage Layout * Water - Domestic tank and supply * Fire protection - Sprinkler provision, smoke purging/extraction, hosereel, hydrant, fire pumps * Gas - pipe layout, incoming location ## Architecture & Electrical Checking for consistency with design of equipment location, lighting provision and lighting protection among other building services in relation to architectural design requirements. Aspects: * Electricity - Substation Design, Lead in, Drawpit * Lighting - Fitting type, illuminance, temperature, lux, positions based on false ceiling layout * Fire safety - Exit Light/Sign, emergency lighting, voice comms, fire alarm panels * Cable/switch types, location & layout - eg. office layout * Fibre optics - Internet * Telephone line * Security systems - CCTV * Lightning Protection System The list above is non exhaustive. *** Architects need to collaborate and prepare the necessary information for effective design: * Site plans with site boundary, buffers, driveway and building layout * Fire plans - locations of hydrants, fire rated walls/compartments * Combined services design layout (CSD) - Underground, high level at all storeys, roof plans * Plans, sections, elevations of buildings * Typical details * Survey plans - with all existing site information (public drains, infrastructure) * Any other relevant design and compliance requirements With tight design collaboration and coordination upstream during a building project, there will lesser issues during construction 🚧. So do not ignore your engineer and blindly assume the design can be built! # Specialist Design Items Architects work with external design specialists in a building project for various aspects of the building that requires special expertise. Example of such specialists include acoustics, lighting, or landscape design, wayfinding, security. \[More details to be added] {% hint style="warning" %} Note: If the specialist design work requires the certification of the Architect, the Architect needs to be aware and familiar with the prevailing statutory codes in order for safe occupancy in future. {% endhint %} # What is Good Building Design? Not just a pretty building...
According to ChatGPT, the following constitutes good building design: * **Functionality:** A good building design should be well-suited to its intended purpose, with appropriate space allocation and efficient use of resources. * **Efficiency:** It should be designed in a way that maximizes the use of space, natural light and other resources, in order to minimize energy consumption and costs. * **Aesthetics:** A good building design should be visually pleasing and reflective of its location, context, and culture. * **Sustainability:** It should be designed with the environment in mind, taking into account factors such as energy efficiency, use of natural light, and the use of sustainable materials. * **Inclusivity:** A good building design should be accessible and inclusive for all users, regardless of their abilities. This includes features such as ramps, elevators, and wide doorways for wheelchair access. * **Uniqueness:** A good building design should be unique, stands out and be reflective of its location, context, and culture. This can be achieved through the use of local materials, traditional building techniques, or a distinct architectural style. * **Human-centered:** A good building design should be designed with people in mind. This means taking into account factors such as natural ventilation, acoustics, and access to natural light, as well as the psychological well-being of the users. {% hint style="info" %} Good building design is subjective, and the above design considerations are not exhaustive, nor must all be met. {% endhint %} When researching projects, try to evaluate from various points of view and determine for yourself if the project is successful in achieving its design objectives. # Drawings & Specifications Proper documentation and drawings for effective construction
When creating construction drawings and specifications, an architect typically includes several key elements to effectively communicate the design intent and technical requirements of a project. **Here are five essential points that architects need to include:** ### **Detailed Architectural Drawings** Construction drawings should provide comprehensive details about the architectural design, including **floor plans, elevations, sections, typical details, and 3D views**. These drawings illustrate the spatial arrangement, dimensions, and relationships of different elements within the building. ### **Structural Layout & Design** Architects need to incorporate structural specifications that outline the requirements for the building's structural components. This includes information on the materials, sizes, and connections of **beams, columns, slabs, and other structural elements** to ensure the stability and safety of the structure. {% hint style="success" %} **Pro Tip:** Drawings should indicate clear headroom, widths especially between structural elements (beam, column to column, load-bearing walls). Include tolerance of minimum 50mm for finishes. {% endhint %} ### **Mechanical, Electrical, and Plumbing (MEP) Systems** The drawings and specifications should include MEP details, such as electrical layouts, lighting fixtures, HVAC (heating, ventilation, and air conditioning) systems, plumbing fixtures, and fire protection systems. These components are vital for the functionality and comfort of the building. ### **Materials & Specifications** Architects need to specify the types, quality standards, and installation methods of various building materials, including finishes, flooring, roofing, doors, windows, and cladding. Material specifications ensure that the project meets the desired aesthetic and performance criteria. {% hint style="success" %} **Pro Tip:** The above information shall be indicated in tender drawings or specifications. Do check and ensure consistency between drawings and specifications. If not, you will receive many requests of information (RFIs) to clarify these discrepancies. {% endhint %} ### **Construction Notes and Details** Construction drawings should contain clear and concise notes and details that provide additional information or instructions to contractors and builders. These may include information about construction techniques, site-specific requirements, sustainability considerations, and any special instructions related to the project. It's important to note that the specific content and level of detail in construction drawings and specifications may vary depending on the scale, complexity, and specific requirements of the project. {% hint style="info" %} **Important** Architects should follow local building codes and regulations, consult with relevant engineering disciplines, and collaborate with other stakeholders to ensure comprehensive and accurate documentation. {% endhint %} # Drafting / BIM conventions BIM (Building Information Modeling) and drafting conventions play a significant role in the creation of construction drawings and specifications.
Here's how they are relevant to the architectural process: ### **BIM (Building Information Modeling):** BIM is a digital representation of a building or infrastructure project that encompasses both graphical and non-graphical information. BIM software allows architects to create intelligent 3D models that contain detailed information about the building's components, materials, systems, and performance attributes. BIM facilitates collaboration among different project stakeholders and improves the accuracy and efficiency of the design and construction process. When creating construction drawings and specifications using BIM, architects can extract relevant information from the model to generate detailed drawings, schedules, quantities, and specifications. ### **Drafting Conventions** Drafting conventions are a set of standardized practices and guidelines followed by architects and drafters when creating construction drawings. These conventions ensure consistency, clarity, and readability of the drawings, enabling efficient communication between the design team and contractors. Common drafting conventions include the use of standardized symbols, line weights, line types, and graphic scales. By adhering to drafting conventions, architects ensure that their drawings can be easily understood and interpreted by all stakeholders involved in the construction process. When incorporating BIM into the drafting process, architects can leverage the intelligent information stored within the BIM model to generate accurate and up-to-date construction drawings. BIM enables automatic coordination between different drawing views, reducing errors and conflicts. It also allows for the generation of 2D drawings directly from the 3D model, saving time and effort. Ultimately, the combination of BIM and drafting conventions enhances the quality and efficiency of the design and construction documentation process, promoting effective collaboration and reducing potential errors or misunderstandings during the construction phase. ### Where to learn drafting and BIM in Singapore? In Singapore, drafting conventions relate to **CP83 (Code of practice for construction computer-aided design (CAD) - CAD symbols) (**[**link**](https://www.singaporestandardseshop.sg/Product/SSPdtDetail/138e9eb3-8ecb-4e86-8fbb-482ee3a9cbce)**)** and there are various **BIM/VDC/IDD guides (**[**link**](https://www1.bca.gov.sg/buildsg/digitalisation/integrated-digital-delivery-idd/idd-resources)**)** as well as upcoming **IFC-SG for Corenet X (**[**link**](https://www1.bca.gov.sg/regulatory-info/building-control/corenet-x/resources/code-of-practice)**).** {% hint style="info" %} Do seek help from your seniors and refer to proper tender and construction drawings (done in BIM) to get up to speed with the various drafting and BIM conventions. {% endhint %} # Gridlines & Dimensions Learn more about plan annotations, such as dimensions and gridlines, and understand the significance of presenting them accurately.

Gridlines and dimensions on a floor plan

Gridlines & Dimensions between gridlines indicate where a building element is placed based from a reference point on plan. These are important for a coordinated placement of building elements such as walls, columns and other structures. The centerlines of these elements are indicated best to accurately position them on site. Naming of these gridlines is crucial to help architects, engineers and builders identify positions of the intersections. Like B2 for the column. Alphabets are typically used for one axis while numbers are used for the other. ### Aligning Gridlines Gridlines are aligned to the center of internal walls and outer face of external walls. This arrangement allows for a fixing of the position of the four corners of the building and footprint to meet planning requirements by authority. For internal walls, the alignment to the center lines of walls allow for a change in thickness of walls as advised by structural engineers without affecting the gridlines. {% hint style="danger" %} ### Do not move grid lines Dimensions between gridlines should be fixed to prevent any confusion. If neccessary, architects should inform all parties before doing so. Should there be any changes to the position of gridlines with respect to the four corners of the building (marked by survey coordinates), architects must update all parties. {% endhint %} # Plans Exploring Scale, Proportion, and Spatial Relationships
Architects come up with plans, drawn at various scales that guide the design, construction, and realization of buildings. I Here we will delve into the key concepts of scale, proportion of spaces, spatial relationships, and the sequence of spaces as they pertain to architectural plans. ### **1) Drawing to Scale** One of the fundamental aspects of architectural plans is scale. Scale refers to the ratio between the size of the drawing and the actual size of the object it represents. In architectural drawings, we commonly encounter three scales: site layout, building plans, and detail plans. Each scale serves a specific purpose in communicating design ideas effectively. 1. **Site Layout:** Site layout plans provide an overview of the entire project site. They depict the location of the building(s), landscape features, parking areas, and access points. The scale for site plans is typically larger, allowing for a comprehensive view of the entire site, including its context within the surrounding environment. This large-scale view helps architects and stakeholders understand the relationship of the building to its surroundings. 2. **Building Plan:** Building plans, often drawn at a smaller scale than site layouts, focus on the interior and exterior layouts of the structure. These plans show the arrangement of rooms, corridors, and other spaces within the building. Architects pay close attention to scale and proportion to ensure that rooms are comfortable and functional. Proportions, such as ceiling heights and room dimensions, influence the overall feel and functionality of spaces. 3. **Detail Plans:** Detail plans are the most intricate and are typically drawn at a larger scale. They zoom in on specific components of the building, like wall sections, staircases, or plumbing details. Detail plans provide construction teams with precise instructions on how to build intricate elements, ensuring that the final product meets the architect's vision. ### **2) Proportion and Spatial Relationships** Proportion and spatial relationships are crucial aspects of architectural design. Architects use proportion to create spaces that are aesthetically pleasing and functional. The relationships between spaces within a building can significantly impact the user's experience. 1. **Proportion and Shape of Spaces:** Achieving the right proportions in architectural design is akin to creating a visual harmony. Architects use mathematical ratios and principles of design to determine the size and shape of rooms and elements within them. A well-proportioned space feels balanced and comfortable, while poor proportions can lead to spaces that feel awkward or disorienting. 2. **Spatial Relationships:** How spaces within a building relate to each other is another key consideration. Architects carefully plan the flow and connectivity between spaces to create a functional and pleasant experience for occupants. \ \ For example, the sequence of spaces in a residential layout might start with an entry foyer, lead to a living room, and then transition to a dining area, all while maintaining a sense of coherence and progression. ### **3) Sequence of Spaces** The sequence of spaces is a narrative that unfolds as one moves through a building. Architects use this sequence to control the user's experience and create moments of surprise, excitement, or tranquility. Think of how a grand entrance hall leads to a breathtaking view or how a series of interconnected rooms can enhance the sense of exploration within a museum. In conclusion, architectural plans are not just technical drawings; they are the manifestation of an architect's vision, considering scale, proportion, spatial relationships, and the sequence of spaces. These plans serve as a roadmap for builders and a means of communication between architects and clients. By mastering these fundamental concepts, architects can create spaces that are not only functional but also beautiful and evocative, enriching the lives of those who inhabit them. # Sections Unveiling Vertical Relationships and Fenestrations that can enhance the Building Design
In the realm of architectural drawings, sections are a vital tool that allows architects to reveal the intricate vertical relationships within a building. Much like the previous page on architectural plans, sections play a pivotal role in conveying design intent. In this article, we will explore the importance of these elements in architectural sections. ### **1) Key Heights of Spaces** One of the primary functions of architectural sections is to elucidate the vertical dimension of a building. By depicting the heights of various spaces, sections provide a clear understanding of a building's volumetric composition. These heights include floor-to-ceiling dimensions, mezzanines, balconies, and any other significant vertical elements within the structure. Architects carefully consider these heights to create spaces that are both functional and aesthetically pleasing. High ceilings can lend a sense of grandeur, while lower ceilings can create cozy, intimate atmospheres. Highlighting these key heights in sections allows both designers and stakeholders to visualize the spatial qualities of the building. ### **2) Vertical Relationships** Sections are instrumental in portraying the vertical relationships between different levels of a building. This includes depicting staircases, elevators, ramps, and other vertical circulation elements. Understanding how people move through a building vertically is crucial for ensuring accessibility and efficient flow. Furthermore, sections reveal the connections between various floors and their relationship to each other. For instance, a section may illustrate how a double-height living room on the ground floor connects visually and spatially with a gallery or bridge on the upper level. These vertical relationships contribute to the overall spatial experience within the building. ### **3) Facade Openings and Airwells** Sections also unveil the intricate details of a building's facade, including window placements, openings, and airwells. These elements have a profound impact on the building's aesthetics, natural lighting, and ventilation. Sections provide a clear view of how these openings align with the interior spaces, emphasizing the importance of views and daylighting strategies in the design. Airwells, in particular, are essential for ventilation and can serve as vertical gardens or light wells, infusing the building with natural elements and enhancing the overall indoor environment. In essence, sections enable architects and stakeholders to assess the effectiveness of these design features. *** In conclusion, architectural sections are indispensable tools for architects to communicate the vertical dimension of their designs. These sections provide a holistic view of how a building comes together, ensuring that the design intent is not only expressed on the horizontal plane but also celebrated in the vertical realm. # Elevations Things to note when preparing architectural elevation drawings
*When preparing architectural elevation drawings, architects should consider several key aspects to ensure accuracy and clarity:* ### **Scale and Proportion** To maintain consistent scale and proportion across the elevation drawing to accurately represent the building's dimensions. This ensures that the drawing is a reliable representation of the intended design. ### **Levels and Heights** To clearly depict different levels and heights in the elevation drawing through level datum lines for all stories. This helps viewers understand the vertical dimension of the building and how different elements align vertically. ### **Detailing** To include sufficient details to convey the design intent clearly. Pay attention to features such as size of doors, windows, facades, and architectural elements. Clearly depict materials and textures to communicate the aesthetic aspects of the design using text or hatch annotations. {% hint style="success" %} ### Pay attention to how elevations are drawn By paying attention to these factors, architects can create elevation drawings that accurately convey the design intent and provide valuable information throughout the construction process. {% endhint %} # Annotation Basics: Plans, Sections & Elevations Annotate your drawings properly with the right line types and symbols on architectural plans, sections and elevations
Architectural drawings use various line types and symbols to convey information accurately. Here are common line types and symbols for architectural plans, sections, and elevations: ### Architectural Plans: 1. **Wall Lines:** * Solid thick lines for cut walls * Solid thin lines for uncut walls * Dashed lines for projected walls * Red lines for special walls (like fire rated walls) 2. **Doors:** * Symbolic representation with swing direction along walls indicated * Arcs or circles to represent doors in the closed position * Door tags to label the door type (to tally with door schedules) * Red lines for fire rated doors 3. **Windows:** * Symbolic representation with panel orientation within wall indicated * Window tags to label the window type (to tally with door schedules) * Arrows indicating window orientation and operation (if applicable, eg. sliding windows) 4. **Stairs** * Symbolic representation for stairs and landings, with arrows indicating the direction from bottom to top of stairs * Lines within staircase boundary lines showing location of step edges * Annotations for dimensions and details (riser height, tread depth, number of risers) 5. **Furniture:** * Symbols for furniture, fixtures, and equipment (FF\&E) 6. **Rooms:** * Outlined areas with tags for room names and dimensions * Room tags may also show key information such as area, finishes for floor, wall, structural or finished floor levels and ceiling and mode of ventilation. 7. **Dimensions:** * Dimension lines with arrows indicating the measurement direction (usually in mm) * Text annotations for dimension values * Clear width of doors, corridors etc 8. **Floor Levels:** 1. Text box label with suffix (eg. SFL, FFL) and a number (eg. 4.00) representing the level at the particular location on plan. 2. Placed within rooms and all key locations where there are varying levels (eg. Building apron, Lift lobby, Corridor) 9. **Symbols for Key Elements:** * Symbols for structural elements like beams, columns, and foundations * Symbols for fire-fighting equipment * Symbols for for landscaping elements such as trees and shrubs 10. **Section/Elevation Lines:** 1. Symbol with line with arrow tail indicating location and orientation of section cut/elevation on plan. 2. Text label within the symbol indicating drawing number and section/elevation number to tally with section/elevation drawing. ### Architectural Sections: 1. **Section Lines:** * Solid thick lines with hatched area to indicate the cut section of wall / floor / ceiling 2. **Materials and Textures:** * Hatching or shading to represent different materials * Annotations specifying material types ### Architectural Elevations: 1. **Outline of Building:** * Solid lines to outline the building * Dashed lines for obscured portions 2. **Doors and Windows:** * Symbols for doors and windows, similar to those in the plan * Indications of swing direction and operation 3. **Roof Pitch and Shape:** * Lines indicating the pitch and shape of the roof * Symbols for roof features like chimneys and vents {% hint style="info" %} **Drafting conventions may vary based on regional standards and individual project requirements.** It's crucial to adhere to industry standards and communicate effectively through clear and standardized symbols and line types {% endhint %} ### Why do we need Tags & Labels? Tags & labels are commonly seen for the following building elements: * Doors * Windows * Walls * Roller shutters * Columns * Beam Schedules provide a tabular format for more information of each building element. For example, you will see door schedules with corresponding labels on floor plan, that indicates the material, fire rating, width, height and other information specific to the door type. # Hatches Learn more about hatch pattern types for different building materials, and understand the significance of presenting them accurately.

Types of hatches

Hatches are 2D patterns in architectural drawings such as plans and sections that represent the type of materials for any surface (wall, floor, roof etc). These are important for effective communication of the correct building materials. *** ## Types of hatches A few basic hatches all parties must recognise in architectural drawings include: * Concrete * Earth / ground * Steel By having a standardised set of hatch patterns for building materials, we have a common understanding on the building design. There will be less miscommunication amongst designers and less errors. *** ### Fun fact Did you know Singapore has its own technical drafting standards, called CP83? It states out the industry standards for CAD drawings, including syntax for layers, linestyles and hatch patterns. # Types of Architectural Practices Scale, project types and Specialisations
There are various kinds of architecture practices, which can be broadly categorized based on scale and project types. ### Scale of practice: * **Large firms:** These firms typically have a large number of employees and handle large-scale projects such as skyscrapers, airports, and large commercial developments. * **Medium firms:** These firms typically have a moderate number of employees and handle a wide range of project types, including commercial, residential, and institutional projects. * **Small firms:** These firms typically have a smaller number of employees and handle smaller-scale projects such as single-family homes, small commercial buildings, and renovations. ### Project types: * **Residential architecture:** These practices specialize in designing homes, apartments, and other forms of residential buildings. * **Commercial architecture:** These practices specialize in designing office buildings, retail centers, hotels, and other forms of commercial buildings. * **Institutional architecture:** These practices specialize in designing schools, hospitals, government buildings, and other forms of institutional buildings. * **Industrial architecture:** These practices specialize in designing factories, warehouses, and other forms of industrial buildings. * **Landscape architecture:** These practices specialize in designing outdoor spaces such as parks, gardens, and other forms of open spaces. * **Interior architecture:** These practices specialize in designing the interiors of buildings, including spaces such as offices, homes, and other forms of living or working spaces. ### Specializations: * **Sustainability:** These practices specialize in designing buildings and spaces that are energy-efficient, environmentally friendly, and promote healthy living. * **Heritage:** These practices specialize in preserving, restoring, and adapting historical buildings and structures. * **Urban design:** These practices specialize in designing and planning for entire neighborhoods, towns, and cities, including the design of public spaces and transportation systems. * **Technology:** These practices specialize in designing buildings that incorporate the latest technology, such as smart buildings, and use of digital tools in design and construction. It's worth noting that many architecture practices will have a combination of these characteristics, and the specific focus of a practice can evolve over time. # Software & Tools for Architects With great tools comes great power!
Architecture is increasingly digitalised. As a young and future architect, software skills are essential. Software are available across all project stages, namely: * Feasibility studies * Schematic design * Detailed design * Render and visualizations * 3D modelling * Drafting and documentation Here's a list of software that architects need to be familiar with: 1. **AutoCAD:** AutoCAD is one of the most widely used software applications for architects. It is a computer-aided design (CAD) software that allows architects to create accurate 2D drawings. AutoCAD offers a range of tools and features for designing and documenting architectural projects. 2. **Revit / ArchiCAD:** Revit and ArchiCAD are building information modeling (BIM) software that are specifically designed for architects and other building professionals. They allows architects to create intelligent 3D models of buildings, which can be used for design, analysis, and documentation purposes. These software also facilitates collaboration among different disciplines involved in a project. 3. **SketchUp:** SketchUp is a versatile 3D modeling software that is popular among architects for its intuitive interface and ease of use. It allows architects to create quick conceptual models, develop detailed designs, and generate presentations. SketchUp offers a vast library of pre-built 3D models and a supportive community that provides additional resources. 4. **Rhino:** Rhino, also known as Rhinoceros 3D, is a powerful 3D modeling software widely used in architecture. It supports both NURBS (Non-Uniform Rational B-Splines) and polygonal modeling techniques, making it suitable for creating complex and organic forms. Rhino offers a wide range of plugins and scripting capabilities, making it highly customizable. It is also the best software to get started on parametric design (learn more in the next post). 5. **Adobe Creative Suite:** While not specifically designed for architects, the Adobe Creative Suite (including software like Adobe Photoshop, Illustrator, and InDesign) is commonly used by architects for graphic design, rendering, and presentation purposes. Architects use Photoshop to enhance rendered images, Illustrator for creating vector graphics, and InDesign for layout and print preparation. 6. **Rendering software (Vray / Twinmotion / Lumion):** Last but not least we need software for visualisation of spaces that can be presented to clients. Vray and Twinmotion as great software to get started to render your 3D models into beautiful 2D graphics, they can even create flythroughs videos. It's worth noting that there are many other software applications used by architects, and the choice of software may vary depending on personal preference, project requirements, and the specific tasks at hand. Most of the time you will need to be familiar with all of the above software (one from each category). If you’re looking to learn software, I highly recommend YouTube or Linkedin Learning. # Building Construction Technologies Learn more about the various building construction technologies here.

Integrated Digital Delivery

We live in an interesting era of building design and construction technologies. Below are the various technologies available for Architects to employ in their building projects to accelerate and improve project delivery and construction. ### 1) IDD (Integrated Digital Delivery) Integrated Digital Delivery (IDD) is the use of digital technologies to integrate work processes and connect stakeholders working on the same project throughout the construction and building life-cycle. This includes design, fabrication and assembly on-site, as well as the operations and maintenance of buildings. **Read more about IDD:** [Integrated Digital Delivery (IDD)](https://www1.bca.gov.sg/buildsg/digitalisation/integrated-digital-delivery-idd) ### 2) Building Information Modelling (BIM)

Image cedit - lodplanner.com

BIM is a digital representation of a building or infrastructure project that encompasses both graphical and non-graphical information. BIM software allows architects to create intelligent 3D models that contain detailed information about the building's components, materials, systems, and performance attributes. BIM facilitates collaboration among different project stakeholders and improves the accuracy and efficiency of the design and construction process. When creating construction drawings and specifications using BIM, architects can extract relevant information from the model to generate detailed drawings, schedules, quantities, and specifications. ### 3) Precast Systems Precast systems refer to a construction method where building components, such as walls, columns, beams, and slabs, are manufactured off-site in a controlled factory environment. These precast elements are then transported to the construction site and assembled to form a complete structure. Precast systems offer numerous advantages, including improved construction speed, enhanced quality control, reduced labor requirements, and increased durability. The use of precast systems allows for efficient and precise manufacturing of building components, resulting in faster project completion, minimized on-site disruptions, and the potential for cost savings. ### 4) Prefabricated Bathroom Unit (PBU) Prefabricated bathrooms units or PBU are complete bathroom units that are manufactured off-site and then transported to the construction site for installation. These pre-assembled modules typically include fixtures, fittings, plumbing, electrical systems, and finishes. Prefabricated bathrooms offer several benefits in the construction industry, including reduced construction time, improved quality control, enhanced cost efficiency, and minimized on-site labor requirements. By being manufactured in a controlled factory environment, prefabricated bathrooms can achieve higher precision and consistency in terms of design and construction quality. The off-site construction also allows for concurrent work, where site preparation and foundation work can progress simultaneously with the production of bathroom pods, leading to time savings. Once delivered to the site, prefabricated bathrooms are quickly installed, reducing on-site construction time, and improving project efficiency. Learn more about PBU: [Prefabricated Bathroom Unit](https://www1.bca.gov.sg/buildsg/productivity/design-for-manufacturing-and-assembly-dfma/prefabricated-bathroom-unit) ### 5) Prefabricated Prefinished Volumetric Consruction (PPVC)
Image credit: Stacked Homes
Prefabricated Prefinished Volumetric Construction (PPVC) is a construction method whereby free-standing 3-dimensional modules are completed with internal finishes, fixtures and fittings in an off-site fabrication facility, before it is delivered and installed on-site. **Learn more about PPVC:** [Prefabricated Prefinished Volumetric Construction (PPVC)](https://www1.bca.gov.sg/buildsg/productivity/design-for-manufacturing-and-assembly-dfma/prefabricated-prefinished-volumetric-construction-ppvc) [PPVC Construction : Why It Matters For Investors (The Good, Bad, And Ugly)](https://stackedhomes.com/editorial/ppvc-construction-why-it-matters-for-investors-the-good-bad-and-ugly/#gs.2mf88g) ### 6) Mass Engineered Timber (MET)
Image credit: Dezeen
Mass Engineered Timber (MET) is a building material comprising engineered wood products with improved structural integrity. This includes: * **Cross Laminated Timber (CLT)**– Layers of wood are stacked cross-wise and bonded with structural adhesives. It is predominantly used for walls, floors and roofs. * **Glued Laminated Timber (Glulam)**– Produced in a similar fashion but with the grain aligned in the same direction. It is predominantly used for columns, beams and truss elements. #### **Why use MET** * **Improved productivity**– As MET is prefabricated offsite, it can achieve up to 35% in time savings at the project level. * **Better construction environment**– Less dust and noise as most work is completed offsite. * **Improved quality control**– Highly precise and automated manufacturing processes results in high quality finishing. * **Environmental sustainability**– MET is harvested from sustainably managed forests, and MET buildings have lower carbon footprint and net carbon emissions compared to steel or concrete buildings **Learn more about Gaia by Toyo Ito, the largest MET building in Asia, sited in Singapore:**

Parametric design has become more prevalent and important in the design and construction of our buildings. It has been touted as one of the biggest changes architecture will see and how work of an Architect will change in the future. *** ## What is Parametric Design? Parametric Design is a design process that utilises programming and geometric data inputs and operations to determine design outputs. To master parametric design, one needs to understand key concepts such as data and parameters, programming concepts & syntax like data structures, functions, conditionals and loops as well the software and tools to get started. The best way to understand programming is to visualise how to bake a cake. There are inputs, ingredients that you need to process step-by-step. After certain conditions are met, be it after an x amount of time or reaching a certain temperature, a cake is created, the output.

Parametric Design - Inputs, Function, Outputs

*** ## Why Parametric Design Is Becoming More Relevant? ### 1) Increasingly Data-Centric World The world is becoming increasingly data-centric. Architects have access to new types of data becoming available. New technologies and systems such as sensors, 3d photogrammetry/web maps, big data, climatic datasets and passenger ridership data allow for a measurement anything quantifiable. With this increasing scale of data sets alongside new technology enablers such as machine learning, generative design, computing, Architects can look forward to have more agency in making design decisions based on relatable data. These data become new constraints and certain criteria and parameters can be set to govern designs. By having more parameters to design problems, more realistic constraints (site plan setbacks, plot ratio, height constraints, building layout, facade design, daylighting, computational fluid dynamics) can be implemented to output numerous unexpected solutions. ‍ ### 2) Numerous Solutions, Ranked For Our Selection, Allowing Us To Make More Informed Design Decisions The parametric design process help Architects make informed design decisions through a set of defined conditions, reducing time and cost required to ideate/analyse design ideas. When design is parametric, the solution can be analysed and ranked. Each solution can be tweaked easily for further analysis, so there is convergence towards a better solution over time and exposure to large precedent datasets. There will be a clear design methodology towards an agreed solution selection. *** ## What Kinds Of Parametric Design Are There? ### Site Plan Scale Using generative design to generate 3D massing/site layout design iterations based on site boundary, setbacks, plot ratio. Constraints such as the site boundary line, building height, GFA, No of storeys etc will need to be input into the system and the system will test as many possible solutions given the parameters. Once the parameters and goals are in place, we run the generative design simulation to capture as many design solutions that fit the criteria. As each iteration is recorded, the system will indicate a numeric score. The generative design algorithm follows how nature is, where it will attempt to 'cross breed' two good solutions and/or create new offspring randomly (mutation). The goal is to keep on finding solutions with the highest score. Over time, the system will find itself converging towards a set of optimal solutions with similar high scores. When the system no longer reports better solutions, the simulation can be stopped and we can assess each solution. **An example of such system is** [**spacemaker.ai**](http://spacemaker.ai/) {% embed url="" %} ### Building Layout Within the building, plan layout of spaces based on circulation / program proximity based on user preferences in a survey can be inputs into a generative design system to create varied options for further evaluation and implementation. A project that utilised such design processes is the **Autodesk MaRS Office: Generative Design for Architecture** An example of a project utilising generative design on a building scale, the Autodesk office in Toronto. The team behind this project identified key criteria to quantify the design options and rank them. They include views to outside, adjacency, daylight, distraction etc. **Learn more about the project:** [Hands-on with Project Rediscover: Generatively Designing the Autodesk Toronto Office](https://medium.com/autodesk-university/hands-on-with-project-rediscover-generatively-designing-the-autodesk-toronto-office-4c10d78a96d3) {% embed url="" %} ### **Facade Design** **Siemens Middle East Headquarters** by Sheppard Robson Architects, Abu Dhabi, United Arab Emirates One example of parametric design being employed in facade design is the Siemens Middle East Headquarters in Abu Dhabi, UAE. The facade perforation design was based on daylighting requirements of spaces and orientation of building. Each aluminium panel is calculated and aligned to optimise the shading and view angles for the occupants within the building based on the sun ray direction along the building perimeter.

These videos are self guided and are step-by-step with visual explanations for your easy learning. In these videos, I share about the fundamentals to get started including: * Types & Application of Parametric Design * How To Get Started * Programming Basics * Data Structures & Syntax * List Syntax & Methods * Functions * Geometry Basics * Constructing Geometry * Geometric Operations {% embed url="" %} ### 2) Have A Hands On Visual Programming Tools & Plugins Use visual programming tools to demonstrate your knowledge as a start. Here is a list of visual programming parametric design tools as well as plugins for extended uses: Visual Programming tools (with the respective design software): * Rhino & Grasshopper * Revit & Dynamo, * ArchiCAD & Paramo If you are completely new, you can read up on the commonly used Rhino-Grasshopper workflow for parametric design via Youtube videos. * [Nick Senske's Youtube Channel on Rhino and Grasshopper](https://www.youtube.com/user/nsenske/playlists)(these are the videos I used to watch when I was getting started) * [Grasshopper Primer](https://www.modelab.is/grasshopper-primer/)(Starter guide to the Grasshopper interface)‍ Try out creating your own scripts based on your own problems. Once you are familiar with the interface, do search for plugins to extend the functionality. These are my recommended plugins for Grasshopper: * [Ladybug](https://www.ladybug.tools/) for environmental analysis * [Elk](https://www.food4rhino.com/en/app/elk) to generate site plans from road maps and building outlines * [Kangaroo](https://www.food4rhino.com/en/app/kangaroo-physics) for physics, force elemental analysis, catenary structures * [Galapagos](https://parametrichouse.com/galapagos/) for generative design ‍ ### 3) Work Your Way Up Lastly, once you have achieved a certain level of understanding of parametric design, spend some time to solve simple design problems towards more complex ones. You should started with parametric form finding and subsequently towards generative design. Examples of simple design projects you can work on include: * Furniture design * Facade patterns/panelisation * Form finding of skyscrapers, massing. {% embed url="" %} Examples of complex design problems include: * Circulation & program organisation based on data inputs * Building massing and orientation design based on climatic data and view corridors. *** ### Further Reading * Parametric House - Resourcses for parametric design * [Grasshopper Primer](https://www.modelab.is/grasshopper-primer/) (Starter guide to the Grasshopper interface) # Parametric Design in Construction Robots can build our buildings too?
In the previous post, we have seen how parametric design is shifting the architectural practice, changing the way we approach the built environment; adopting more data-centric workflows and thus informing the design process. Here, we dive deeper into the actualisation of this new architecture and how with input from other industries such as manufacturing, we are able to bring the construction of the built environment into the 21st century. *** ## **What Is Its Role In Construction**? Apart from generating design options and optimisation within a design space, parametric tools have the capability to bridge the design and the building process. Essentially, a building is an agglomeration of components that are manufactured separately. By specifying architecture with great detail in the 3D space, we are able to translate this information for construction by breaking it down into manufacturable components. Hence, by creating a design-to-fabrication workflow, we are able to close the gap between the digital model and the physical construction process Data-driven design approaches create nonstandard architecture, often requiring customised components. Fortunately, today’s 3D model is a more than just an onscreen geometrical representation. Using parametric tools, quantifiable parameters (shape, volume, size etc.) can be extracted for manufacturing/fabrication feasibility. > *design → optimisation + rationalisation → building components → fabrication/manufacturing strategy → manufacturing instructions → built product* *** ## How Does This Change Construction? ### **Empowering Designers** A more data driven design can be manufactured with ease by adopting a digital fabrication workflow i.e. file-to-factory documentation that allows the design to go from a design to a final form production. Complex geometries are broken down into manufacturable components to be manufactured in the process of Mass Customisation, giving the designer greater dexterity in the design process. ### Working On A Collective Model Adopting a complete digital workflow allows designers to accelerate traditionally complex modelling by building a feedback loop of design and construction information; preserving the aesthetic whilst ensuring a design is realisable. ### Improve Efficiency Of Construction Parametric design workflows open up opportunities for modular construction of components, reducing redundancy, time on site and reducing the physical workload on humans by leveraging on machinery for the manufacturing of components. *** ## **How Is It Done?** By engaging in varying manufacturing methods (e.g. additive and subtractive), we are able to mass customise construction components for the built environment, through whats known as digital fabrication. We are also able to engage digital workflows in the assembly process, allowing for larger and more complex building components. Digital fabrication is a workflow where digital data directly drives the manufacturing process, primarily from CAD models. Robotic fabrication is an extension of this sphere, leveraging on industrial robotic arms to extend the scale of manufacturable components. These methodologies are entirely possible in a 3D environment like Rhino, using parametric tools such as Grasshopper. Robust plugins have also been developed within academia and the open source [grasshopper community](https://www.food4rhino.com/en) to control industrial arms, namely, [KUKA PRC](https://www.food4rhino.com/en/app/kukaprc-parametric-robot-control-grasshopper), [TACO ABB](https://www.food4rhino.com/en/app/taco-abb), [Hal Robotics](https://www.food4rhino.com/en/app/hal-robotics-framework) etc. Using these plugins, fabrication tool paths can be directly generated from the 3D model.

*** ## **What Can It Do?** ### **Additive Manufacturing** Additive manufacturing (AM) or additive layer manufacturing (ALM) is the industrial production name for 3D printing, a computer controlled process that creates three dimensional objects by depositing materials, usually in layers. Additive Manufacturing provides a material and energy efficient way to quickly produce architectural components of varying complexity. Design information can be directly translated into additive manufacturing ready files that will be used to directly manufacture these components.

The introduction of robotic arms, extends the possibilities of CNC milling, enhancing the dexterity of the possible cuts with the higher number of axes of movement. Laser cutting and hot wire, conventional model-making techniques, also fall within this category of subtractive manufacturing.. For example, [Woodchip Barn](https://www.dezeen.com/2016/02/23/architectural-association-students-london-robotically-fabricated-barn-dorset-woodland/) built by AA’s Design & Make students, consists of 25 timber forks harvested from the forest that were 3D scanned and milled to form the interlinking connections that form the spine of the structure.

{% embed url="" %} *** ## **Examples Of Robotic Fabrication & Automation in Construction** Robotic Fabrication opens up the possibilities of digital fabrication by allowing architectural components to be made at varying scales, limited only by the working area limitations of the robots employed. Here we look at examples of robotic fabrication at differing scales. ### Small: *Facade Elements* ITeCons Laboratory's Facade At the smallest scale, robotic fabrication can be used for making decorative elements such as facade panels, interior design and product scale that can transform the quality of spaces. An example of this is the ITeCons Laboratory’s facade in Coimbra.

ITeCons Laboratory's Facade

Learn more about the project: [ITeCons Laboratory's Facade](https://dfl.arq.up.pt/portfolio/itecons-facade/) ### *Medium: Bridge* Apart from decorative elements, individual structural components can be fabricated in a single process such as concrete 3D printing. These parts can then form a larger architectural work that is fully structural and standalone, such as [Striatus](https://www.striatusbridge.com/), a project by Block Research Group (BRG) at ETH Zurich and Zaha Hadid Architects Computation and Design Group (ZHACODE) as seen in the video below. {% embed url="" %} Striatus, a project by Block Research Group (BRG) at ETH Zurich and Zaha Hadid Architects {% endembed %} Learn more about the Project: ### *Large: Prefabricated Buildings* As a response to labour shortages brought about the pandemic and a reduction in available skilled manual labour, construction industries are increasingly curious about automating building assembly processes. The key challenge to overcome at this scale is the nature of the multistage process of manufacturing. Working either autonomously or collaboratively with human beings, robots are able to streamline the design to fabrication to assembly process, reducing the workload of the human being to that of supervision and planning of fabrication and assembly processes. For example, the [Spatial Timber Assemblies ](https://dfabhouse.ch/spatial_timber_assemblies/#:~:text=Spatial%20Timber%20Assemblies%20is%20an,the%20level%20of%20structural%20complexity.)is an innovative prefabrication process for timber frame modules. It combines timber frame construction with the precision and speed of robotic fabrication, regardless of the level of structural complexity.

Designers can develop interest and research around materials and building techniques, prior to upscaling it. The flexibility of industrial robotic arms offers freedom to designers to explode the limits of the material and geometry made possible with parametric design. One example is [BUGA Fibre Pavilion](https://www.itke.uni-stuttgart.de/research/built-projects/buga-fibre-pavilion-2019/), a recent public project as part of the fibre winding research conducted at the University of Stuttgart. Researchers are intrigued by the material properties of fibre composites and speculate its use as building material. As fibre composites are usually fabricated with molds, the researchers took a winding approach to create large scale differentiated hollow structure for architectural purposes. As the building technique does not exist yet, researchers adopted robotic fabrication to generate instructions and syntaxes for this mode of construction using parametric tools from ground up.

*** ## **Digital Workflow: How Does It All Come Together?** Often, multiple software are used for architectural projects, impeding productivity. This issue is alleviated now, with increasing software interoperability. Establishing a pipeline for software to communicate and exchange information in real time allows stakeholders to work collaboratively on the fly. More importantly, this pipeline can stream data to robots for production and is capable of interpreting feedback, thus, creating a cyber-physical loop. This relationship can then enhance the product quality or foster dynamics between the human and machine within the creative domain. Following are a few examples that bridge existing software in the industry. ‍ ### Design Stage #### CAD → 3D [Rhino Worksession](http://docs.mcneel.com/rhino/5/help/en-us/commands/worksession.htm) is great for linking CAD drawings real-time within the Rhino environment. This allows stakeholder to make changes and visualise updates across computers. #### 3D ↔ BIM [Rhino.Inside.Revit](https://www.rhino3d.com/inside/revit/1.0/) allows one to use rhino+grasshopper natively within the Revit environment. It is also bi-directional. Using this, rationalised design can return to Rhino+Grasshopper as geometries for fabrication. Tool paths, target position and manufacturing constraints can be generated and simulated. ### Production Stage #### 3D → Robot As mentioned earlier, Robotic fabrication relies on a software pipeline to connects design to production. The efficiency depends largely on the smoothness of the integrated workflow. [Grasshopper](https://www.grasshopper3d.com/) is a flexible platform for connecting design directly to industrial robots. Plug-ins can also be developed to communicate with robots and embedded systems. This can be done either in real time or generating manufacturing instructions to be loaded onto the robots, otherwise known as offline programming. *** ## **How To Get Started** ### **Try The Toolkits (Grasshopper)** Here are a list of robot toolkits available. These are toolkits you can use in grasshopper to program the robots directly using geometric data coming through a rhino-grasshopper workflow. * [KUKA PRC](https://www.food4rhino.com/en/app/kukaprc-parametric-robot-control-grasshopper) * [TACO ABB](https://www.food4rhino.com/en/app/taco-abb) * [Hal Robotics](https://www.food4rhino.com/en/app/hal-robotics-framework) * [Robots by Visose on Github](https://github.com/visose/Robots) Robotic fabrication also requires entry level understanding of computation and mathematics such as matrices and inverse kinematics etc. ### **Be Familiar With Programming** Also, programming literacy is highly recommended for advancement beyond basics. Here are some of useful resources that provides easy entry in the context of design. * [Essential Mathematics for Computational Design](https://developer.rhino3d.com/guides/general/essential-mathematics/)‍ * Python, C# * C, C++ (for people who wants to start interfacing with hardware) ### **Explore Possibilities** View projects from these online resources: * [Fabricate Conference](http://www.fabricate.org/) *** ## Conclusion Digital and robotic fabrication is not about reinventing the wheel or complicating the process of making but it serves as an avenue to extend an artisan’s capability. It can unlock new design aesthetics or expedite collaboration between stakeholders. Design goes beyond the aesthetic and regulatory, and is now holistic through its ability to cater for manufacturing and assembly from the initial stages. Although scaling and efficiency remains a point of debate, the intrinsic dynamic between building science and design will continue to supercharge the development of this emerging workflow for all scales of architecture. *** ## **Special Credit - CmdR** Thanks cmdR for writing the content on this page. cmdR specialises in robot programming, workflow design and software integration.

Artificial intelligence (AI) is expected to play a significant role in the future of architectural practice by assisting architects in various stages of the design process, from conceptualization to fabrication. 1. **Generating and Evaluating Design Options**: AI can be used to generate and evaluate design options, optimize building performance, and automate tedious tasks such as building code compliance checking. 2. **Utilizing big data to inform design:** AI can be used to analyze large amounts of data, such as building usage patterns, to inform the design of buildings that are more responsive to the needs of their users. AI will not replace Architects {% hint style="info" %} ### AI will not replace Architects AI is not a replacement for the creativity and critical thinking of architects, but rather a tool to enhance and augment their abilities as well as to accelerate workflows. {% endhint %} # Social Architecture What is social architecture and why is important?
Social architecture is an approach to architecture that focuses on the social aspects of design and the role that architecture can play in shaping and improving communities. Here are five key points summarizing what social architecture is: 1. **People-centered:** Social architecture places a strong emphasis on the needs and desires of the people who will use the space, rather than simply focusing on aesthetics or functionality. 2. **Community building:** Social architecture aims to promote social interaction and community building through the design of public spaces, shared spaces, and community facilities. 3. **Inclusion:** Social architecture strives to create inclusive spaces that are accessible to all members of the community, regardless of their abilities or backgrounds. 4. **Empowerment:** Social architecture aims to empower communities by involving them in the design process and giving them a sense of ownership over their built environment. This is also called co-creation. 5. **Sustainability:** Social architecture often incorporates sustainable design principles, such as green spaces and energy-efficient building systems, to create healthy and livable communities. *** ## Why Is Social Architecture Important? People should be at the heart of any architectural design project. By understanding how people think, say and act, Architects can design for better, more holistic solutions in the buildings. Ultimately, spaces should take into account the interconnectivity between people, place and activity, through Observation & Research, Mapping & Analysis, Co-creation & User input. *** ## The Key Aspects Of Social Architecture We begin with the three aspects that makes social architecture - people, activity and place. Studying each aspect and understanding the connections/ meaning across them will aid us architectural designers to create vibrant, sustainable social spaces for the community. ### People What is social architecture without the people? Here we are looking at the following when it comes to design research and goals: * Communities * Psychology * Sociology * Mindsets * Identity ### Activity Apart from people, we should also study events that occur which can also play a part in our design decisions in social architecture. We are focusing on the following: * Events (private vs public, individual vs group) * Time of event * Routines ### Place Lastly, we should also study the importance of what makes a place 'the place', with key ideas such as: * Typologies * Climate data * Icons (cultural, social) * Landscape * Objects *** ## How to get started ### Find Meaning And Connections Architects should discover the interconnections between people, place and activity. Research can be done through Observation & Research, Mapping & Analysis, Co-creation & User input. By performing research, one will better understand the meaning of place and why people do certain activities with specific people. ### Ethnography & Research Methods We can design for a more social architecture by proper research of people, activity and place. Once there's a proper and tested hypothesis, we can proceed to design the architectural solution.

Summary of various research methods

### Behavioral Mapping - AEIOU Method The AEIOU Method is a methodology to perform a holistic analysis of a site. AEIOU stands for: Activity\ Environment\ Interactions\ Objects\ Users ### Fieldwork Techniques These techniques includes Photographs, Recorded observation of users, Timelapses, Interviews *** ## Conclusion To get started on social architecture, one can start by developing a empathy for the group of people you personally connect with. By fully understand users and occupants pains, journeys and stories, Architects can propose the most impactful design.\ \ Architects interested in social architecture should conduct interviews, gather data, seek quantitative data that justifies qualitative data to a hypothesis before starting to design. *** ### Special Thanks The Singapore University of Technology & Design Architecture & Sustainable Design course has a module called 20.31 Social Architecture: Theory and Practice conducted by Dr. Chong Keng Hua.

These projects showcase the potential for architectural interventions to breathe new life into existing buildings and transform them into iconic landmarks. # Building Compliance Basics Comply or die trying to construct your building.
## What is compliance? Compliance is process where Architects and Engineers plan site layout and design buildings according the planning parameters and statutory requirements in place by building authorities. All requirements listed in building regulations and statutory acts are required by law with possibility of incurring a fine, time imprisonment and/or both if the qualified persons (Licensed Architect/Professional Engineer)signing off falsely declare full compliance when submitting to the authorities. Most building design should be able to comply with the ‘prescriptive[^1]’ code. Otherwise, qualified persons can seek alternative ways to demonstrate compliance by simulations and/or waivers (exceptions granted by the building authority.) ### Why compliance? * To ensure the safety of occupants in the building and also neighbouring buildings * To ensure coherence of building design/site layout with the urban context * To ensure proper connection of services, drains and public utilities * To ensure adequate provision of facilities for the well-being of occupants (etc public toilets, noise control, vehicle parking) * To ensure adequate building performance, constructability, sustainability. ### Overview of the Compliance Process Plan approval is required by statutory law before the main contractor can construct the building. Architects submit to the building authorities through drawings and calculations, to show the compliance to the various building and planning codes.
Preliminary Design (Development Control) Planning parameters must be complied. Key items to be established: GFA, Strata area, Plot Ratio, Site layout, Building Setback & Building Height etc
Detailed Design (Building Plan) Building layout finalised and submitted for approval before construction. Key items to be established: Building layout, fire safety, service provisions etc
Construction To follow exactly approved plans. If not, to submit amendment plans to building authority before proceed with the changes. Architects must regularise deviations from approved plans to avoid abortive works.
Completion (Occupation) Building constructed to approved drawings, on-site inspection and verification.
*** [^1]: Prescriptive code refers to code requirements that are by default and stipulated in building codes and regulations where Qualified Persons must comply # Communication & Negotiation Key skills for Architects, explained
Architects need to be proficient in various types of communication and negotiations skills to effectively convey their design ideas, collaborate with clients and stakeholders, and coordinate with construction teams. ## Communication types required for Architects Some key types of communication architects should be aware of include: ### 1) **Visual Communication** Architects must possess strong visual communication skills to express their ideas through drawings, sketches, and 3D models.

An architectural feasibility study is a method used by architects to assess the viability of a project before moving forward with its design and construction. Here are some steps an architect might undertake during a feasibility study: 1. **Research on zoning codes:** The architect initially investigates if the client's desired use and/or improvement is permissible on the intended site. 2. **Assessment of site feasibility, opportunities, and limitations:** The architect conducts a preliminary review of the potential and challenges of the site being considered for purchase, as well as the neighboring properties. 3. **Development of a project program:** The architect creates a program detailing the client's needs and specifications for the project. 4. **Consulting with an in-house real estate broker:** The architect may seek advice from an in-house real estate broker to evaluate the market potential for the proposed project. 5. **Cost analysis:** The architect carries out a cost analysis to ascertain the financial viability of the project. *** {% hint style="info" %} ### What is the difference between a feasibility study and site analysis? As for the distinction between a feasibility study and site analysis, a site analysis is the examination of a site's physical and environmental attributes, while a feasibility study evaluates the economic and technical practicality of a project. In essence, a site analysis focuses on a site's physical aspects like topography, soil conditions, and vegetation. In contrast, a feasibility study determines the financial and technical feasibility of a project. {% endhint %} # Site Planning & Analysis How to start and things to consider Here's a short summary on how an architect should approach site analysis and site layout planning: ### **1) Understand the Context** Begin by comprehending the site's physical, historical, cultural, and environmental context. This includes factors like climate, topography, neighboring structures, underground services, nearby infrastructure (roads, footpaths, bus stops) and local regulations (setbacks and buffers). Take photos for easy reference. ### **2) Obtain Existing Topographical / Survey Plan** Appoint a registered surveyor to come up with the topographical survey plan to document existing features, such as roads, trees, soil conditions, utilities, neighbouring buildings and any restrictions that may affect the design. This plan should be in CAD and adjusted to SVY21 format for accurate siting of your buildings and ease of coordination. Do check for the site boundary line and ensure all coordinates (northings and eastings) are indicated in the survey plan. ### **3) Test Out Massing and Layout** Familiarize yourself with local planning laws and building codes. Ensure that your design complies with these regulations. Plan the site's layout- start to position your buildings and driveways, considering factors like circulation, parking, landscaping, and outdoor spaces. Prioritize efficiency and accessibility. Orientate building fenestrations away from west to reduce solar heat gain in your buildings. ### **4) Accessibility** Prioritize accessibility by considering access points, clear wayfinding/pathways for all users (vehicles and pedestrians). Do consider connectivity to various transport nodes such as bus stops, cycling paths and train stations. Also consider public and private access points. ### **5) Aesthetics and Visual Appeal** Pay attention to aesthetics and visual harmony. Create a coherent design that complements the surroundings and enhances the site's beauty. Have a dialogue with the urban context. {% hint style="info" %} ### Different site, different approach. Remember that every site is unique, and the approach to site analysis and layout planning should be tailored to the specific characteristics and requirements of each project. By following these best practices, architects can create innovative, functional, and sustainable spaces that enrich the built environment. {% endhint %} # Concept Design What is a architectural design concept and things to consider. Architects wield immense creative power during the concept design phase. Architects should approach concept design, focusing on form, circulation and program, building orientation, and project brief integration. ## Key Considerations ### Form Finding: Shaping the Vision 1. **Site Context:** Analyze the surroundings, climate, and local context to shape your design. 2. **Inspiration:** Seek inspiration from various sources to develop your design concept. 3. **Conceptual Sketches:** Experiment with different forms and materials through sketches. 4. **Materiality:** Choose materials that align with your design vision and sustainability goals. ### Circulation and Program: Ensuring Functionality 1. **User-Centric Approach:** Prioritize user needs by engaging with clients and stakeholders. 2. **Flow and Accessibility:** Plan for intuitive circulation and space efficiency. 3. **Program Layout:** Allocate spaces efficiently and design for adaptability. ### Building Orientation: Harnessing Natural Elements 1. **Solar Analysis:** Optimize building orientation for natural light and energy efficiency. 2. **Ventilation and Climate Control:** Consider wind patterns and climate conditions for passive cooling. 3. **Views and Privacy:** Balance scenic views with privacy considerations. ### Incorporating Project Brief Requirements: Balancing Vision and Functionality 1. **Detailed Analysis:** Scrutinize the project brief for constraints and goals. 2. **Collaboration:** Maintain open communication with clients and adapt to changing requirements. 3. **Iterative Process:** Be prepared to refine your design based on feedback. In summary, concept design is where architectural creativity meets functionality. Architects must consider form, functionality, orientation, and project requirements in a balanced manner. Tailoring each approach to the project's context and goals leads to designs that satisfy clients' needs and leave a lasting architectural legacy. # Design Methods Exploring architectural design methods that an Architect can perform when approaching building design. Architectural design is a multifaceted process that demands creativity, innovation, and a deep understanding of various design methods. There are various types of approaches to craft buildings that not only fulfill their functional requirements but also leave a mark on the built environment. Below are some key design methods that architects can use to shape their projects. ### 1. **Site-Inspired Design: Where Context Reigns** One of the fundamental approaches to architectural design is drawing inspiration from the site context. Architects keenly observe the surroundings, climate, topography, and cultural aspects of the location to create a design that harmonizes with its environment. This method ensures that buildings become an integral part of their surroundings, blending seamlessly with nature and local aesthetics. It's an approach that values sustainability and cultural sensitivity. ### 2. **Form Finding: Geometry as Iconography** Another captivating design method is form finding, where architects focus on the visual impact and geometry of their creations. These designs often aim to become iconic landmarks within a cityscape. By playing with innovative shapes, lines, and volumes, architects create structures that capture the public's imagination and stand as symbols of their time. The emphasis here is on aesthetics and the transformative power of architecture in defining a city's identity. ### 3. **Historical and Cultural Context: Honoring Heritage** Respecting history and cultural heritage is a design method that transcends time. Architects draw from the past to create buildings that pay homage to tradition and heritage. Incorporating elements from different architectural styles or reinterpreting historical motifs can result in structures that resonate with a sense of timelessness and cultural significance. This approach bridges the past and the present, connecting people to their history. ### 4. **Research-Driven Design: Refining Through Knowledge** Architects are often scholars of their craft, and research-driven design is a method rooted in in-depth study. By researching building typologies, materials, and construction techniques, architects develop innovative solutions and hypotheses to refine their designs. This approach fuels experimentation and can lead to groundbreaking architectural advancements.

In conclusion, the importance of building height and site coverage in architectural and urban design cannot be overstated. These factors impact not only the safety of airspace and military operations but also the aesthetic, functional, and environmental aspects of a site. Achieving the right balance between building height and coverage is essential to creating sustainable, visually appealing, and harmonious urban environments that meet the needs of both residents and the larger community. Architects, urban planners, and policymakers must work together to strike this balance, taking into account the unique characteristics and goals of each site, and incorporating innovative design strategies to address the complex challenges of the modern built environment. # Clear Width & Heights Allow for tolerance; do not design too precisely Establishing clear widths and heights stands out as a fundamental task that architects and designers must undertake with utmost care. In this article, we will explore the importance of setting clear widths and heights in architectural design to ensure safety for occupants, avoid non-compliance and abortive work to rectify them. ## **Defining Clear Widths and Heights** Before delving into the reasons behind the significance of clear widths and heights, let's clarify what these terms mean in the realm of architectural design: * **Clear Width:** Clear width refers to the unobstructed, open space between two fixed points, typically measured horizontally. This measurement is crucial for various reasons, such as ensuring accessibility, defining circulation paths, and complying with safety regulations. * **Clear Height:** Clear height pertains to the vertical measurement of unobstructed space between the floor and ceiling or between two fixed points. Clear height considerations are vital for ensuring proper headroom of minimum 2 metres and creating functional spaces that adhering to design and standards. ## **Accommodating Additional Space for Finishes & Services** One of the key aspects of establishing clear widths and heights that often goes overlooked is the need to accommodate additional space for finishes. Finishes encompass a wide range of materials and elements, including wall coverings, baseboards, trim, and more. Services encompass light fittings, fire protection systems, ventilation ducts and more that usually run overhead. Setting aside extra space for finishes & services serve as a prudent design strategy for several reasons: ### **1. Accessibility Compliance** Accessibility is a crucial consideration in modern architectural design. Clear widths must adhere to accessibility standards to accommodate individuals with mobility challenges, such as those using wheelchairs or walkers. By incorporating extra space for finishes, designers can ensure that the clear width remains compliant even after the installation of finishes. ### **2. Fire Safety Requirements** Clear widths also play a pivotal role in fire safety. In the event of an emergency evacuation, unobstructed and sufficiently wide corridors are essential for safe passage. Designing with extra space for finishes can help maintain the required clear width even when considering potential protrusions like wall-mounted fire extinguishers or handrails. ### **3. Workmanship Considerations** In any construction project, achieving absolute precision in workmanship can be a challenge. Small variations or imperfections can occur during installation. By allocating extra space for finishes, architects and designers provide a buffer that can absorb these imperfections, ensuring that the final result meets the intended design standards. For example, when planning the clear width of a corridor, adding an extra 50mm (or more) for finishes along the walls can compensate for any discrepancies in the alignment of baseboards or wall coverings (eg. plastering). This attention to detail enhances the overall visual quality of the space. *** ## **Practical Applications** ### **Clear Width** Let's consider a practical example to illustrate the importance of accommodating additional space for finishes. Imagine designing a hotel corridor with a clear width requirement of 1,200mm to comply with accessibility guidelines and fire safety regulations. By planning for an extra 50mm on each side for finishes, the total clear width would be 1,300mm. In this scenario, even if the installation of wall coverings or baseboards results in slight misalignments, the corridor's clear width remains comfortably above the minimum requirement of 1,200mm. This not only ensures compliance with regulations but also enhances the corridor's appearance and functionality. ### Clear Height Consider a modern office building where architects, in pursuit of creating a sleek and minimalist interior, design a lobby with a stunningly low ceiling. However, they fail to account for the necessary overhead services like lighting fixtures, air conditioning vents, and fire sprinkler systems. As a result, these services end up infringing on the already limited headroom of min 2.0m, not only compromising the aesthetic vision but also creating an uncomfortable and cluttered space for occupants. This oversight highlights the importance of meticulously planning clear heights to ensure that both functionality and design intent are seamlessly integrated into the final architectural vision. *** ## **Conclusion** In the intricate world of architectural design, every detail matters. Establishing clear widths and heights is a foundational step that architects and designers must undertake with precision and foresight. By accounting for additional space for finishes and overhead services, especially in the context of structural elements like columns and structural floor to floor height, design professionals can address workmanship issues, maintain accessibility compliance, ensure fire safety for safe occupancy in future. # Floor Levels Definition of levels, use cases and the importance of establishing levels early on in the design.

Overview of floor level annotation used in architectural practice

## What is a level? A level indicates how high an element is placed based from a universal height datum/reference. It is represented by a numeric value which specifies the height above sea level. Floor levels are to be indicated on all floor plans & sections for a few reasons: * To indicate vertical locations of floor slabs, roofs, canopies, and any horizontal surfaces. * Statutory requirements like platform level to better understand how the building is integrated with the existing terrain/context ## Types of Levels Structural Slab Level - Underside of the slab Structural Floor Level - Top level of the slab before architectural finishes Finished Floor Level - Top level above architectural finishes *** ### Fun fact - Did you know Singapore's mimimum platform level is 104m/105m above sea level? This is set by the Public Utilities Board (PUB) Code of Practice (Drainage). It is to safeguard our buildings from flood risk. For example, the platform level 104m above sea level is indicated as PL +4.00. *** ## Common levels to be established: From bottom to top: * Level outside the development * Driveway Level * Apron Level * First Storey Level (Minimum Platform Level) * Upper Storey Levels (consider floor to floor heights) * Roof Level (top of roof slab or bottom of roof eaves for sloped roofs) {% hint style="info" %} ## Pro Tip: Establish levels early It is important to establish working levels early to prevent any miscommunication and errors in the construction of the building elements. Architects are in charge of establishing the levels mentioned above as all the engineers will refer to the same levels for their designs. Should there be any changes, architects must inform all parties to follow suit. It is important to establish working levels early to prevent any miscommunication and errors in the construction of the building elements. Architects are in charge of establishing the levels mentioned above as all the engineers will refer to the same levels for their designs. Should there be any changes, architects must inform all parties to follow suit. {% endhint %} # Slope Gradients Learn the importance of establishing the right slope gradient **Slope gradient represents how steep a ramp is.**\ **It is represented by a ratio of rise to run.** Or its height and length respectively. The smaller the unit of run vs 1 unit of rise, the steeper the slope is. Thus a 1:8.3 slope is steeper than a 1:15 one. ## **Common gradients:** **(slope gradient listed are the maximum allowed and are non-exhaustive)** 1 : 2 - Steepest slope for earth without need for ERSS\* 1 : 8.3 - Steepest vehicular access slope 1 : 10 - Equipment ramp 1 : 12 - Wheelchair ramp 1 : 15 - Fire Engine deployment, heavy vehicles straight ramp 1 : 20 - Curved ramps for heavy/articulated vehicles (20/40ft trailers) 1 : 25 - Handicap Ramp without need for handrails 1 : 30 - Drainage gradient for public roads 1 : 100 - Screed to fall for roof drainage 1: 200 - Screed to fall for workshops drainage # Floorplate Efficiency Unlocking Space: Calculating Floorplate Efficiency Floorplate efficiency is a key concept in architectural and real estate design that quantifies how effectively a building's floor space is utilized. In a world where space is at a premium, understanding and maximizing floorplate efficiency can make a substantial difference in the functionality and profitability of a structure. At its core, floorplate efficiency measures the ratio of usable floor space to the total floor area. It helps architects and developers determine how efficiently a building can accommodate various functions, from offices and apartments to retail spaces. Achieving a high floorplate efficiency means making the most of every square meter or square foot. {% hint style="info" %} To calculate floorplate efficiency, divide the net usable area by the gross floor area and multiply by 100 to get a percentage. A higher percentage indicates better efficiency. {% endhint %} Efficient floorplate design not only optimizes space but also enhances user experience, reduces operational costs, and can potentially increase property value. It's a fundamental consideration in modern urban planning and architecture, where every inch matters. So, next time you step into a well-designed office, residential tower, or shopping mall, remember that the concept of floorplate efficiency played a crucial role in making the most out of that space, offering you a more functional and enjoyable environment. # Natural vs Mechanical Ventilation To achieve thermal comfort and building regulation required ventilation in their buildings, Architects need to cater for adequate natural or mechanical ventilation. In this post, we will dive into the definitions and kinds of ventilations to understand how they work and their respective advantages. ## Key Terms **Ventilation** — Natural or induced movement of air within a space **Natural Ventilation** — Ventilation without the use of any systems/technology **Mechanical Ventilation** — Ventilation via the use of systems & technology (ie. air supply and exhaust ducts — ACMV) **Area to be ventilated**- Space within the room that requires fresh air **Opening area** — Size of holes/ gaps through the façade to an external space **Effective opening area** — Area to be used for calculations which may be different from the area of the opening itself. **Airwell** — Vertical shaft that serves as ventilation for spaces abutting it **CMH** - Cubic metre per hour, a unit of measurement for airflow or flow rate: **Airflow -** CMH is used to measure the airflow of a ventilating fan. The performance of a fan is plotted on a performance curve, with CMH along the horizontal axis. *** ## **Natural Ventilation** **Definition:** Natural ventilation is a passive system that relies on the movement of outdoor air through a building's design features, such as windows, doors, vents, and thermal buoyancy, to provide fresh air and remove stale indoor air. ### **Kinds of Natural Ventilation** 1. **Cross-Ventilation:** This is the most common form of natural ventilation. It involves creating openings on opposite sides of a building, allowing outdoor air to flow through. 2. **Stack Ventilation:** In stack ventilation, the principle of warm air rising is utilized. Hot air naturally accumulates near the ceiling, creating a pressure difference that draws fresh air in through lower openings and expels warm air through higher vents or openings. 3. **Windcatchers:** Windcatchers are traditional architectural elements commonly found in arid regions. They capture and direct prevailing winds into the building, creating a cooling effect. Windcatchers are especially effective in naturally cooling indoor spaces. ### Key Design Concepts for Natural Ventilation 1. **Proximity to Airwells and External Spaces**: 1. Airwells and external spaces play a pivotal role in facilitating airflow. Buildings are often designed with strategically placed airwells or courtyards to enhance cross-ventilation (within 12m from all areas of the space to be naturally ventilated), drawing cooler air into the interior and allowing warm air to escape. 2. Direct access to external spaces maximizes exposure to prevailing winds, typically from the northeast and southeast due to Singapore’s monsoon seasons. 2. **Effective Area of Openings Relative to Room Size**: 1. For optimal ventilation, the effective area of openings (windows, vents, or louvers) should be at least **15-20% of the room's floor area**. Larger openings promote better airflow, while their placement—such as on opposite or adjacent walls—supports cross-ventilation. 2. **Influence of Louvres and Sliding Windows**: * **Louvres**: While louvered windows allow airflow even when partially closed, they reduce the effective area by 50% compared to fully open windows due to the inclined slats, which can obstruct some airflow. * **Sliding Windows**: Sliding windows often result in a reduced effective ventilation area, as only half of the window's total area is open at any time. Careful placement and sizing are needed to offset this limitation. 3. **Ventilation Pathways and Height Differences**: * Incorporating high and low openings in the same space enhances natural ventilation by leveraging the stack effect, where warm air rises and exits through higher openings, drawing cooler air in from below. ### **Advantages of Natural Ventilation** * Energy Efficiency: Natural ventilation requires no mechanical systems, reducing energy consumption and operational costs. * Connection to Nature: It enhances occupants' connection to the outdoor environment, promoting well-being. * Sustainability: It aligns with sustainable design principles by reducing reliance on artificial cooling and heating systems. ### Practical Applications To achieve effective natural ventilation: * Align openings with prevailing wind directions. * Incorporate airwells or courtyards in dense developments. This approach balances functionality with urban context and humid climate, ensuring sustainable and comfortable indoor environments. *** ## **Mechanical Ventilation:** **Definition:** Mechanical ventilation is an active system that uses mechanical devices, such as fans, to supply and exhaust air. It is designed to provide consistent and controlled indoor air quality. It is measured by air changes per hour (ACH). ### **Kinds of Mechanical Ventilation:** 1. **Supply-Only Ventilation:** In this system, fans supply fresh outdoor air into a building, creating a positive pressure environment. Stale air is allowed to exit through natural leakage points. 2. **Exhaust-Only Ventilation:** Here, fans are used to remove indoor air, creating a negative pressure that draws fresh outdoor air in through openings like windows and vents. 3. **Balanced Ventilation:** Balanced ventilation systems use both supply and exhaust fans to maintain a neutral pressure within the building. This allows for precise control over indoor air quality. ### **Advantages of Mechanical Ventilation** * Consistency: Mechanical ventilation systems can maintain a consistent indoor air quality regardless of external conditions. * Precision: They allow for precise control of ventilation rates, humidity levels, and filtration, which can be essential in healthcare and laboratory settings. * Adaptability: Mechanical systems can be integrated with heating, cooling, and air purification systems, offering comprehensive climate control. *** ### **Choosing the Right Ventilation Strategy** The choice between natural and mechanical ventilation depends on various factors, including climate, building design, occupancy, and energy goals. In some cases, a hybrid approach may be suitable, combining the benefits of both strategies. Ultimately, the goal of any ventilation system is to provide occupants with clean, comfortable, and healthy indoor air. Whether achieved through the passive elegance of natural ventilation or the precise control of mechanical systems, proper ventilation is a cornerstone of modern building design and occupant well-being. Architects and engineers carefully consider these strategies to ensure that the spaces they create are not only aesthetically pleasing but also conducive to a healthy and comfortable lifestyle. # Driveway Design Catering for vehicular access Designing driveways is an essential aspect of architectural practice that blends functionality, safety, and accessibility. Typically, these driveways do not only serve cars, but service vehicles such as fire engines, ambulances, lorry/trucks for loading and unloading, refuse trucks and buses. Thus, we need to ensure proper driveway design that will cater for all of these vehicles. Here are the key concepts to grasp when planning driveways: *** **1. Access Points** * The location and number of driveway access points significantly impact traffic flow and safety. Do check with the urban design guidelines in your country to set the access points. * Ensure access points are strategically located to minimize congestion and align with road junctions or pedestrian pathways. Note access points cannot be too close to bus stop, pedestrian crossings and junctions (about 20-25m). * For separate ingress and egress along the same road, as a rule of thumb, the ingress should be positioned first before the egress for smooth traffic flow. * For mixed developments, separate entry and exit points for the public and private access to enhance circulation and reduce potential conflicts. * Try to position access point near destinations (carparks etc) *** **2. Driveway Width** * The width of the driveway depends on the number of lanes and the presence of dividers: * Single-lane driveways typically require **3.0–3.6 meters**. * Dual-lane driveways should have a minimum width of **6.0 meters**. * Include extra width if a divider is present to accommodate turning movements. * Always check your country building codes for the latest requirements. *** **3. Driveway Turning Radius** * Adequate turning radii ensure smooth vehicular movement, especially for large vehicles like fire engines and refuse trucks. * Plan intersections and corners with generous curves to avoid vehicle overhang or conflict. * Use simulation software such as AutoTURN to access driveway width and turning radii required. Check out the required vehicle dimensions and wheelbase setting out for proper simulations. *** **4. Driveway Length and Perimeter Access** * For fire safety, ensure the driveway provides access around the **building’s perimeter**. * In high-rise developments, fire engines must have clear and unimpeded routes to critical points, such as the building’s entrance or designated staging areas (example: hydrants, breeching inlets, fire escape staircases). * Maintain driveway lengths that allow vehicles to queue without obstructing public roads. (Example: entrances should allow for 2 cars waiting space without affecting public road) *** **5. Driveway Gradients** * Gradients affect both accessibility and safety: * **Maximum incline:** **1:8.3 (12%)** for general use. * **Fire engine deployment incline:** No steeper than **1:15 (6.67%)** to enable stable positioning. * **Entrance approach gradient:** Keep transitions gentle with a maximum of **1:10 (10%)** for a smooth and safe approach. *** **6. Driveway Cul-de-Sac (Dead Ends)** * Dead-end driveways should include a cul-de-sac or a turning area for vehicles to maneuver efficiently. * For larger vehicles, design a hammerhead turning area for 3 point turns. *** {% hint style="info" %} Driveway design is more than just creating a path for vehicles; it requires a detailed understanding of safety codes, vehicular dynamics, and site functionality. Balancing these factors will not only ensure compliance with regulations but also enhance user experience and safety. By mastering these key principles, you can integrate driveway design seamlessly into your projects, contributing to efficient and well-thought-out developments. {% endhint %} # Lighting (Daylighting vs Artificial) Let there be light. Lighting is a critical component of architectural design, influencing functionality, aesthetics, and sustainability. Effective integration of daylighting and artificial lighting ensures comfortable, energy-efficient, and visually appealing spaces. Below are the key considerations for each type of lighting. *** ### **Daylighting Design Considerations** Daylighting uses natural light to illuminate interiors, reducing reliance on artificial lighting while creating a connection to the outdoors. Key factors include: 1. **Building Orientation** * Align windows and openings to maximize exposure to natural light. * In tropical climates like Singapore, prioritize east-west shading to reduce glare and heat gain. 2. **Window Placement and Size** * Position windows to achieve even light distribution. * Larger windows on north- and south-facing walls provide consistent daylight without excessive glare. * Use clerestory windows or skylights for deeper penetration of light. 3. **Glazing and Shading** * Opt for high-performance glazing to minimize heat gain and UV exposure while maximizing light transmission. * Incorporate shading devices like louvers, overhangs, or blinds to control glare and prevent overheating. 4. **Light Shelves** * Horizontal shelves placed near windows reflect daylight deeper into the interior, improving light distribution while reducing direct sunlight and glare. 5. **Reflective Surfaces** * Use light-colored walls, ceilings, and finishes to enhance the spread of daylight. * Reflective surfaces can amplify daylighting in spaces with limited openings. 6. **Zoning for Daylight Use** * Design workspaces, reading areas, or communal zones to take advantage of natural light. * Private or less-used areas can rely more on artificial lighting. *** ### **Artificial Lighting Design Considerations** Artificial lighting complements daylighting and ensures functional illumination during the night or in spaces without access to natural light. Consider the following: 1. **Lighting Levels** * Follow standard recommendations for illumination based on activity: * **Task lighting**: 300–500 lux for workspaces. * **Ambient lighting**: 100–200 lux for general areas. * **Accent lighting**: To highlight architectural features or décor. 2. **Lighting Types** * **Ambient Lighting**: Provides overall illumination, typically using ceiling-mounted fixtures or recessed lights. * **Task Lighting**: Focused light for specific activities like reading or cooking. * **Accent Lighting**: Adds visual interest by highlighting architectural features, artworks, or textures. 3. **Lighting Fixtures** * Choose fixtures that suit the space's function and aesthetic. * Ensure easy maintenance, especially in high-traffic areas. 4. **Energy Efficiency** * Use LED lights for lower energy consumption and longer lifespan. * Incorporate smart lighting controls, such as dimmers and motion sensors, to reduce energy use. 5. **Color Temperature** * Select appropriate color temperatures based on mood and activity: * Warm light (2700–3000K): Creates a cozy, relaxing ambiance for homes or hospitality spaces. * Neutral light (3500–4000K): Suits offices and retail environments for clarity and focus. * Cool light (5000–6500K): Ideal for task-intensive areas like hospitals or laboratories. 6. **Integration with Daylighting** * Design lighting systems that adjust to natural light levels, using daylight sensors or dimmable fixtures. * Reduce artificial lighting in areas with abundant daylight. 7. **Glare and Visual Comfort** * Avoid excessive brightness contrasts by carefully positioning lights and using diffusers or indirect lighting. *** {% hint style="info" %} Successful lighting design is a balance between daylighting and artificial lighting, each complementing the other to create functional and sustainable spaces. By considering orientation, materials, and modern lighting technologies, architects can enhance user comfort, reduce energy consumption, and add aesthetic value to their designs. Thoughtful integration of lighting ensures that both natural and artificial illumination work harmoniously to enrich the built environment. {% endhint %} # Designing for Fire Safety Overview of Fire Safety in Architectural Design Fire safety is a fundamental aspect of architectural design, ensuring the protection of occupants, property, and emergency responders in the event of a fire. Here’s an overview of fire safety principles for both **building scale** and **site layout**, with key considerations for each. *** ### **1. Purpose Group** **Fire safety requirements will depend on the Purpose Group (PG), which is the main function of the building.** For example, Singapore classifies the buildngs into various Purpose Group starting from least hazardous to most. The more hazardous the PG is, the more strict requirements are. PG 1 - Small residential (Residential dwelling house, such as: bungalow, detached house, semi-detached house & terrace house) PG 2 - Other residential (Accommodation for residential purposes other than any premises comprised in PG I, such as: apartment, cluster housing, condominium flat, maisonette, town house) PG 3 - Institutional (Education/Training facilities, Worker lodging, Healthcare) PG 4 - Offices PG 5 - Shops PG 6 - Factory PG 7 - Place of Public Resort (Communal facilities, Hotels, Museums, Auditoriums, Stadiums, Transport Facilities) PG 8 - Warehouse (storage of goods/vehicles eg: Carpark, Coldroom) *** ### **2. Building Scale** **Compartmentation** * Compartmentation is the limitation of extents of a space that is protected by fire rated elements (walls, slab) by height and/or cubic volume. * Also used to separate spaces of different purpose groups. * Fire rated walls and doors are used to 'compartment' these spaces to prevent fire spread. * Fire rating will depend on purpose of the space. The more hazardous the use, the higher fire rating required. * If compartmentation is not feasible, the provision of sprinkler is required. **Means of Escape vs. Occupant Load Calculations** * **Occupant Load**: Determine the maximum number of occupants for each space based on its use and size. * **Means of Escape**: Ensure exits are adequate to accommodate the calculated occupant load, factoring in capacity and evacuation time. **Travel Distance to Nearest Exit** * Limit the maximum travel distance to the nearest exit to ensure swift evacuation. * Check your local fire code for the applicable max travel distance (1-way and 2-way, depending on program) **Exit Provisions** * **Number of Exits**: Provide at least two exits for rooms and spaces exceeding the occupant load threshold. * **Clear Width of Exits**: Maintain clear widths (e.g., **900mm for single exits**, more for larger loads). * **Separation of Exits**: Ensure exits are well-separated to prevent a single fire from obstructing all routes. * **Protected Corridors/Staircases**: Design fire-rated, smoke-free paths leading directly to external spaces. * **Exit signs and exit directional signs:** To direct occupants towards nearest exit. **Firemen Access** * **Facade Openings**: Incorporate accessible openings for fire brigade operations. * **Breeching Inlet**: Provide inlets at strategic locations to allow firefighters to connect water supplies. * **Fire Lifts**: Include fire-rated lifts with independent power and fireproof shafts for firefighter use. * **Hosereels**: Position hosereels for coverage of all spaces within 30 meters. **Building Materials and Fire Safety Products** * Use fire-rated materials for walls, floors, and structural elements, ensuring compliance with required fire-resistance durations (e.g., **1–4 hours**). * Install certified fire doors, fire stops, and smoke seals in critical areas. **Fire Protection Systems** * **Sprinkler Systems**: Automatically suppress fires in sprinklered buildings. * **Detectors and Alarms**: Install smoke and heat detectors to alert occupants promptly. * **Manual Call Points**: Place at exits and in prominent locations for manual alarm activation. * **Emergency Voice Communication Systems and alarm monitoring**: For real-time monitoring and communication with fire post during emergencies. *** ### **3. Site Layout** **Fire Engine Accessway Provision** * **Length and Perimeter**: Ensure accessibility for fire engines, with a minimum clearance width of **4.0 meters for access road**. **6.0 meters for fire engine accessway.** * **Turning Radius**: Design accessways with turning radii suitable for fire engines. **Hydrant and Breeching Inlet Locations** * **Hydrant Placement**: Position fire hydrants within **50 meters** of a breeching inlet or building entry points. * **Breeching Inlets**: Locate inlets near main accessways for easy connection by the firefighters. *** ### **Integration and Compliance** * Follow local fire codes and regulations to ensure designs meet the fire safety requirements * Typically, the more hazardous the building program, the more strict the requirements are. * Fire safety plans are to be submitted and approved before construction. * There are 2 kinds of compliance: Prescriptive and Performance Based. * Prescriptive: Where the design is following the applicable Fire Code. * Performance-based: Where the design cannot comply to Fire Code and requires additional fire engineering assessment. Do engage early with fire safety engineers and authorities to review plans for compliance. *** {% hint style="info" %} Fire safety design requires a comprehensive approach that considers both the building's internal layout and its integration with the surrounding site. By addressing means of escape, fire protection systems, and access provisions for emergency responders, architects can create environments that prioritize occupant safety while meeting regulatory requirements. Balancing functionality and safety is key to effective fire safety planning. {% endhint %} # Sustainable Design Saving the world one building at a time. Sustainable design is integral to modern architecture, aligning environmental responsibility with occupant comfort and operational efficiency. The [**BCA Green Mark 2021**](https://www1.bca.gov.sg/buildsg/sustainability/green-mark-certification-scheme/green-mark-2021) provides a comprehensive framework for sustainability. Here are key design considerations based on its principles: *** ### **1. Energy Efficiency** Efficient energy use reduces operational carbon footprint and energy costs. * **Building Envelope**: Optimize **RETV** (Residential Envelope Thermal Value) and **ETTV** (Envelope Thermal Transfer Value) with low **U-values** for walls and windows, and incorporate sunshading devices. * **Active Systems**: Use energy-efficient ACMV (air conditioning and mechanical ventilation) systems, and aim for zero/positive energy buildings. * **Renewable Energy**: Integrate on-site solar panels or other energy generation systems. * **Daylighting and Natural Ventilation**: Design for optimal daylight access and cross-ventilation, using strategic building orientation and layouts. *** ### **2. Whole Life Carbon** Address the full lifecycle impact of materials and construction. * **Embodied Carbon**: Select sustainable materials and reduce carbon-intensive processes. * **Concrete Usage Index**: Minimize traditional concrete use by adopting **green concrete** or recycled concrete aggregates. * **Sustainable Systems**: Opt for prefabrication, modular construction, and **Mass Engineered Timber (MET)** for reduced waste and emissions. *** ### **3. Resilience** Enhance the building's adaptability to environmental challenges. * **Urban Heat Island (UHI) Mitigation**: Use reflective materials, green roofs, and high-albedo finishes. * **Green Plot Ratio**: Maximize greenery with native plants, vertical gardens, and green roofs. * **Circularity**: Incorporate waste management systems and facilities for composting and recycling. *** ### **4. Intelligence** Leverage technology for smarter, more efficient buildings. * **Active Demand Control**: Install systems to adjust energy usage based on demand. * **Digital Twin**: Use digital models for efficient facility management and predictive maintenance. * **Energy Monitoring**: Provide dashboards for real-time tracking of energy consumption. *** ### **5. Health & Wellbeing** Design for occupant comfort and wellness. * **Indoor Air Quality**: Use low-VOC materials and ensure effective ventilation systems. * **Acoustics**: Incorporate noise mitigation measures for occupant comfort. * **Green & Blue Spaces**: Provide access to nature, such as gardens or water features, and ensure proximity to parks or green corridors. * **Mobility**: Include bicycle racks, end-of-trip facilities, footpaths, and spaces for inclusive activities. *** ### **6. Maintainability** Ensure buildings are easy to maintain over their lifespan. * Design with safe and accessible maintenance zones, such as walkways on rooftops or accessible service shafts. * Use durable, low-maintenance materials to minimize lifecycle costs and disruptions. *** ### Conclusion Sustainable design is a multifaceted approach that integrates energy efficiency, material consciousness, resilience, intelligence, occupant wellbeing, and maintainability. By adopting the [**BCA Green Mark 2021**](https://www1.bca.gov.sg/buildsg/sustainability/green-mark-certification-scheme/green-mark-2021) framework, architects can create buildings that are not only environmentally responsible but also adaptive, comfortable, and efficient for long-term use. # 03 - Building Components, Materials & Specifications In this chapter, learn more about the parts that make a building a building.

Finishes in architecture serve two main functions: **protection** and **aesthetics**. They enhance the durability of materials, improve resistance to environmental factors, and contribute to the overall look and feel of a space. Choosing the right finish is as important as choosing the material itself, as incompatible finishes can reduce performance and even cause material failure. This article provides a summary of **common finishes**, their correct applications on various building materials, and highlights commonly misunderstood or misapplied combinations. *** ## **Types of Finishes** #### **1. Paint** A liquid or mastic composition that, when applied to a surface, forms a protective and decorative coating. * **Acrylic Emulsion Paint** – Used for interior walls and ceilings * **Enamel/Alkyd / Oil-Based Paint** – Durable, used for timber and metal surfaces * **Epoxy Paint** – Industrial-grade, highly resistant to chemicals and abrasion * **Intumescent Paint** – Fire-resistant coating used on steel #### **2. Powder Coating** A dry finishing process where a free-flowing, dry powder is electrostatically applied and cured under heat. Provides a **durable, uniform, high-quality** finish. #### **3. Laminate** A thin layer of material (plastic, veneer, or film) bonded to a substrate. Commonly used for **timber products, furniture, cabinetry, and interior wall panels**. *** ## **Common Building Materials and Compatible Finishes** | Material | Suitable Finishes | Common Locations | Notes | | -------------------- | ------------------------------------------------------------------------- | ------------------------------------------------------------ | ------------------------------------------------------------------------------------------------------- | | **Stainless Steel** | Brushed, polished, hairline, bead-blasted | Railings, lift interiors, signage | Avoid painting unless special primers are used. Maintains self-protecting oxide layer. | | **Galvanised Steel** | Paint (with primer), powder coat (if degreased and primed), epoxy coating | Railing, linkway/roof structures, fences, structural framing | ⚠️ *Powder coating directly over galvanised steel without surface prep can cause peeling (outgassing)*. | | **Aluminum** | Anodising, powder coating, fluoropolymer coating | Facade cladding / rainscreens, window frames | ⚠️ *Painting directly on aluminum without etching primer leads to poor adhesion*. | | **Timber** | Stain, varnish, lacquer, oil, paint | Doors, feature walls panels, flooring | Depends on wood species.

Understanding the right finish for the right material is critical to delivering a building that stands the test of time and climate, especially in humid tropical climates like Singapore. In future articles, we’ll dive deeper into **performance-based selection of coatings**, **green-certified finishes**, and **detailing for long-lasting performance** in architecture. # Tile Types and Design Considerations Master the basics of tiles, the most common architectural finishes in any building project Tiles are one of the most commonly used architectural finishes, known for their durability, versatility, and aesthetic appeal. Whether used for floors, walls, bathrooms, or thresholds, proper selection and detailing are critical to ensuring long-term performance and visual consistency. This article outlines the different types of tiles, materials, key design considerations, and common on-site mistakes to avoid. *** ## **Classification of Tiles by Use** | Application Area | Typical Tile Type | | ----------------------------- | --------------------------------------------------- | | **Internal Floors** | Homogeneous, ceramic, porcelain, timber-look tiles | | **External Floors** | Porcelain (R11+), granite, anti-slip textured tiles | | **Bathroom Floors** | Slip-resistant ceramic or porcelain (R10–R11) | | **Wall Tiles (Accent Tiles)** | Glazed ceramic, porcelain, decorative tiles | | **Threshold Tiles** | Wide transition tiles at door/entrances | | **Nosing Tiles** | Nosing tiles with anti-slip finish (50mm - 75mm) | *** ## **Tile Materials** * **Porcelain Tiles**: Dense, low water absorption, ideal for high-traffic areas. * **Ceramic Tiles**: More porous than porcelain, suitable for light-use areas. * **Homogeneous Tiles**: Uniform colour throughout; scratch and wear-resistant. * **Timber-look Tiles**: Porcelain or ceramic with woodgrain design. * **Stone-look Tiles**: Mimic granite or marble with textured finishes. * **Granite Tiles**: Natural stone, highly durable but more expensive. *** ## **Slip Resistance Ratings (Singapore Standards)** Slip resistance is critical, especially in wet or outdoor areas. In Singapore, slip resistance is generally specified using **DIN 51130 ramp test ratings**: | Rating | Application | | ------- | --------------------------------------------- | | **R9** | Dry indoor areas only | | **R10** | Bathrooms, kitchens, semi-wet zones | | **R11** | Outdoor areas, wet rooms, commercial kitchens | > Refer to BCA's "Good Industry Practices – Flooring" and SS 485:2011 (Singapore Standard for Slip Resistance Classification). *** ## **Typical Tile Sizes** | Size (mm) | Common Usage | | ----------------------------------- | ----------------------------------------------- | | 300 x 300 | Bathrooms, feature walls | | 300 x 600 | Residential floors and walls | | 600 x 600 | Living and dining floors | | 900 x 150 | Timber-look tile planks | | Large Format (1200 x 600 or larger) | Commercial or high-end residential floors/walls | *** ### **Types of Tile Patterns** * **Stacked/Aligned**: Aligned grout lines, clean and modern look * **Offset**: Staggered tile patterns for a more dyanmic look * Herringbone: Staggered in 2 directions. *** ### **Best Practices in Tile Installation** * Avoid small cut tiles (<50mm) at edges and thresholds * Minimise **lippage** (height difference between adjacent tiles) * Align floor and wall tiles, especially in bathrooms * Choose tile size that fits the room with minimal cutting * **Size rooms in increments of 50mm** for easier tile setting out * Used mitre joints at corners to eliminate visible edge trims *** ### **Tips for Tile Setting Out** * Start tile layout from the entrance and work inwards * Align tiles with major features: **windows, doors, cabinetry** * Avoid narrow tile strips at room entrances * Maintain alignment across rooms and wall junctions * Dry lay tiles to check pattern and symmetry before installation *** ### **Communicating Tiled Finishes to Contractors** Architects typically communicate tile finishes through the following documents: * **Architectural Specifications**: Describe tile material, size, slip resistance rating, joint types, adhesives, and grout colour. * **Finishes Schedule / Finishes Plan**: Annotated floor plans showing location, type, and code of finishes in each space (e.g. 600x600 homogeneous tile, R10). * **Tile Setting Out Plans & Elevations**: Detailed drawings indicating setting out point, layout grids, alignment and joint lines in relation to fixtures and openings. These help avoid cut tiles at doors and ensure continuity across rooms as well as alignment of tile lines from floor to wall. * **Section Details**: Include thresholds, skirting junctions, transitions to other finishes (e.g. carpet or vinyl), and waterproofing build-up in wet areas. > Tip: Always coordinate tile setting out with floor traps, doorways, and window frames early in the design stage to reduce site improvisation and rework. *** ### **9. Common Errors to Avoid** | Mistake | Result | | -------------------------------- | ------------------------------------ | | Using wrong slip-resistance tile | Safety hazards in wet areas | | Misaligned tiles | Poor visual outcome, rework needed | | Small cut tiles at entrances | Unprofessional finish | | Poor setting out | Visible tiling errors, poor symmetry | | Grout colour mismatch | Distracts from tile pattern | *** ### **Conclusion** Tiles, while common, require thoughtful design and precise execution. Choosing the right material, slip rating, size, and layout approach will go a long way in delivering a high-quality finish that is both functional and visually consistent. Proper setting out, coordination with architectural elements, and knowledge of best practices will significantly improve workmanship and performance. *** **References:** * SS 485:2011 – Slip Resistance Classification (Singapore) # Types of Walls and Wall Systems Walls are fundamental elements of a building that serve both structural and spatial functions. Choosing the right type of wall is not just about structural requirements—it also involves considerations of constructability, acoustic and fire performance, cost, sustainability, and compliance with regulatory frameworks like BCA's Buildability Framework and Green Mark in Singapore. This guide breaks down the different types of walls, their characteristics, and key considerations for architects to make informed decisions during design and documentation. *** ## **1. Classification of Wall Types** ### **1.1 Load-Bearing Walls** These walls support the weight of structural elements above, such as slabs, beams, and roofs. * **Examples**: Reinforced concrete walls, AAC load-bearing walls, brick masonry walls (low-rise) * **Use Case**: Core walls, external structural walls, party walls in landed houses ### **1.2 Non-Load-Bearing Walls** These walls serve only as partitions or enclosures. * **Examples**: Drywalls (gypsum), lightweight block walls, partition walls * **Use Case**: Internal partitioning, room subdivisions, corridor enclosures *** ## **2. Key Design Considerations for Selecting Wall Types** | Consideration | Impact on Selection | | ------------------------- | -------------------------------------------------------------------------------------------------------------------------------------- | | **Labour Intensity** | Wet trades (e.g., RC walls, brick walls) are labour-intensive. Drywall systems reduce manpower. | | **Sustainability** | Use Green Mark certified systems and recyclable materials like drywall and AAC blocks. | | **Cost** | Includes material, installation, and finishing costs. Lightweight systems may reduce structural load and cost. | | **Acoustic Performance** | Critical for party walls, residential units, and offices. Drywall with insulation can perform well. | | **Fire Rating** | Certain spaces (e.g., riser shafts, escape corridors) require FRL-compliant walls. | | **Wall Thickness** | Impacts usable floor area. Drywalls offer thinner profiles than block or RC walls. | | **Finish Compatibility** | Heavier finishes (tiles, stone cladding) require walls with sufficient load-bearing capacity. | | **Buildable Score** | Lightweight and prefabricated wall systems score higher under BCA’s buildability framework for Labour Saving Index (LSI) | | **Green Mark Compliance** | Materials with low embodied carbon and good lifecycle ratings contribute positively. SGBC labelled products are best for this purpose. | *** ## **3. Common Wall Systems – Summary Table** | Wall System | Load Bearing | Advantages | Disadvantages | | ------------------------------------------------ | ------------------ | ---------------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------- | | **Drywall (Gypsum Board)** | No | Lightweight, fast installation, good acoustic rating (with insulation), Green Mark certified options | Limited impact resistance, not suitable for wet areas without treatment | | **Lightweight Precast Concrete Panel** | Yes/No | Prefabricated, high buildable score, consistent quality | Crane required, heavy, transportation and coordination needed | | **Autoclaved Aerated Concrete (AAC) Block Wall** | Depends on density | Lightweight, fire resistant, good thermal insulation, easy to cut | Brittle, not ideal for anchoring heavy items without support | | **Precision Block Wall (e.g., hollow blocks)** | No | Good dimensional accuracy, less finishing required | Labour intensive, moderate acoustic performance | | **RC Wall (cast-in-situ)** | Yes | High structural integrity, excellent fire rating | Time-consuming, wet trade, low buildability score | | **Brick Wall (Clay or Cement Bricks)** | Depends on density | Traditional aesthetics, high durability | Very labour intensive, low speed of construction | *** ### **4. Actionable Tips for Architects** * **Match wall type with function**: Use drywall or AAC for internal partitions; RC or precast concrete for structural cores or wet areas. * **Factor in wall thickness early**: Coordinate wall types with M\&E and space planning to avoid clashes and lost space. * **Think buildability from Day 1**: Propose wall systems that improve BCA Buildable Design Score. Use precast wall systems for higher LSI and Buildable Score. * **Align with Green Mark**: Select certified wall systems and finishes with environmental declarations (SGBC products) * **Plan finishes accordingly**: Tiled or heavy cladded walls require stronger substrates—coordinate wall types with finishes. * **Acoustic Ratings -** Refer to product specifications for acoustic ratings eg. STC * **Fire Requirements**: Refer to SCDF codes for wall ratings required in different building types (e.g. 1-hour fire rating for risers). *** ### **Conclusion** Understanding wall systems goes beyond technical specs—it impacts cost, speed, compliance, and user comfort. Architects play a key role in proposing practical, code-compliant wall types that enhance constructability while aligning with sustainability goals. Always balance performance with practicality, and communicate clearly through specifications, wall type legends, and detailed drawings. *** **References:** * BCA Buildable Design Appraisal System (2022) * SCDF Fire Code * Green Mark Certification Standard for New Buildings (GM:2021) # Common Mistakes in Covered Linkway Design Covered linkways are a staple in public and residential developments across Singapore, providing sheltered connections between buildings, transport nodes, and communal amenities. While they may seem like straightforward structures, poor detailing or coordination can lead to major functional and maintenance issues down the line. Based on common pain points observed in practice, here are seven key mistakes to avoid when designing covered linkways — especially those with free-fall roofs discharging to house drains. *** ## 1. **Overcomplicating Roof Geometry with Curved Structures** While curved linkway roofs may appear more elegant, they introduce complexity at intersections. When connecting to other perpendicular roofs, a seamless connection is hard to achieve without: * Having a separate roof at the connection, or * Raising the height of one roof to allow rainwater to fall cleanly onto another (i.e., free-fall principle). **Good Practice:**\ Use simple pitched roofs for easier interfacing. This allows for clearer rain discharge routes and simplifies structural and flashing details. *** ## 2. Roofs should not f**ollow ramp gradients without Proper Roof Discharge** It may seem logical to follow the slope of an accessibility ramp with the linkway roof, but without a proper rain discharge strategy, water can stagnate. **Why It’s a Problem:** * No gutters are allowed (due to mosquito breeding risk per NEA regulations). * Sloped roofs without fixed discharge levels may direct water back toward pedestrian walkways. **Good Practice:**\ Maintain a *fixed roof level* independent of ramp gradients. Let rainwater discharge via eaves away from the walkway, with downflow directed to adjacent drains. *** ## 3. **Inadequate Sections — Especially at Building Interfaces** Failing to draw enough sections, particularly where the linkway connects to a building, often results in unclear flashing details. **Result:**\ Contractors may improvise or dispute missing information, leading to water ingress or compliance issues. **Good Practice:**\ Cut detailed cross and longitudinal sections showing roof-to-wall connections, flashing, and junction details clearly. *** ## 4. **Misaligned Roof Eaves and House Drains** When the eave of the linkway roof doesn’t line up with the house drain, rainwater splashes onto walkways instead of being captured effectively. **Good Practice:**\ Align the drip edge of the roof directly over the house drain, ensuring water falls cleanly into it. *** ## 5. **Inadequate Coverage from Rain** A frequent complaint is that rain still gets into covered walkways due to poor sizing or misalignment of the roof. **Good Practice:**\ Design for lateral rain (driven by wind) by ensuring: * Sufficient roof width and overhang (exceeding 1:1 ratio of height and width) * Vertical rainscreen can be added to mitigate wind-blown rain from side directions. * Consider prevailing wind directions in your orientation of linkways to mitigate wind-driven rain. *** ## 6. **Incorrect Column Positioning** Columns that are too close to the edge of the roof may lead to constructability issues or affect flow of rainwater. **Good Practice:**\ Set columns *at least 300–600mm inboard* from the roof eaves to allow for proper overhang, maintenance access, and visual clarity. *** ## 7. **Roof Eaves Too Close to Driveways** If the eaves of a low linkway roof overhang too close to driveways, they are at risk of vehicular damage (e.g., by tall vans or service vehicles). **Good Practice:**\ Maintain *a minimum 600mm setback* between the eave and any vehicular path. Coordinate with traffic movement paths and height clearances. *** ## Final Thoughts Designing covered linkways requires an appreciation of function, maintenance, and alignment with urban infrastructure. Many of these mistakes stem from insufficient coordination between architectural, civil, and structural inputs — so early-stage cross-discipline reviews are key. # 04 - Building Project & Contract Administration In this section, we will cover key concepts and tips on project & contract administration.

For young architects, understanding this is critical — not only for proper project execution but also for protecting yourself and your client throughout the construction process. *** ## 1. Types of Building Contracts There are various types of contracts used in the Singapore construction industry, depending on the project scale, delivery method, and party relationships. Here’s a breakdown: ### By Mechanism * **Measurement Contracts**\ Payment is based on actual quantities of work done, typically measured from drawings and site progress. Suitable when the scope is not fully defined.\ *Contractor prices per item or work unit (e.g., per m² of tiling). Final contract value depends on actual work.* * **Lump Sum / Fixed Price Contracts**\ A single contract price is agreed upon for the entire project. Variations can still occur, but the base price remains unchanged unless adjusted.\ *Common for traditional SIA contracts or Design & Build.* * **Design & Build (D\&B)**\ A single entity (contractor) is responsible for both design and construction. Employer sets out **Employers’ Requirements (ERs)** and **Employers’ Notional Design**, which contractors use as a basis to bid a **lump sum price**.\ *Faster delivery but less design control for the architect unless engaged directly.* ### By Standard Form * **SIA Building Contract (Singapore Institute of Architects)**\ Commonly used for private-sector projects. Architect is the contract administrator and impartial certifier. * **PSSCOC (Public Sector Standard Conditions of Contract)**\ Standard for government projects (HDB, LTA, BCA, etc.). Typically used with measurement contracts and more procedural requirements. * **REDAS Design & Build Contract**\ Used by private developers for design-and-build developments. Prioritises speed and single responsibility through the contractor. * **Subcontract Agreements**\ Used between main contractor and subcontractors (e.g., M\&E trades). Architects typically do not administer these. * **Minor Works Contract**\ For projects with smaller scopes (e.g., under $1M). Simpler terms and processes, fewer formalities. * **NEC4 Contract (Collaborative Contracting)** \ According to Mr. Sathia Jagateesan, Partner at law firm Allen & Gledhill LLP, said “Collaborative contracting allows project parties to have better time and cost control, better management of risks and efficient project management. Compared to conventional lump-sum contracts, collaborative contracts such as NEC4 contract provides a target cost option which allows project parties to share cost savings or overruns when they occur. This could encourage project parties to resolve issues early and explore more productive solutions together.” Check out my list of building contracts here: {% content-ref url="/pages/H7z87q34U04BlNcDnldM" %} [Contract Types (Singapore)](/contract-types-singapore) {% endcontent-ref %} *** ## 2. Key Contract Mechanisms (Chronological Order) Here are the main mechanisms and milestones that occur in a typical project timeline. The list is not exhaustive. 1. **Commencement of Works**\ Contract signed, site handed over, and Notice of Commencement issued. 2. **Submittals and Approvals**\ Contractor submits shop drawings, material samples, and method statements for approval by consultants. 3. **Progress Claims and Payment Certificates**\ Contractor submits monthly claims. Architect or QS assesses and certifies payments via interim certificates. 4. **Variations (VOs)**\ Any change to the contract scope or specifications. Can add or omit works and affect cost/time. 5. **Extensions of Time (EOT)**\ If delays are not the contractor’s fault (e.g., weather, late approvals), they can apply for more time. Usually within 14 days of the event (check contract clause). 6. **Retention Sum**\ A portion (commonly 5-10%) of each payment is withheld to ensure the contractor completes outstanding works and fixes defects. Half is released upon Practical Completion, the rest after the Defects Liability Period. 7. **Delays and Liquidated Damages (LDs)**\ If the contractor delays the project without approved EOT, LDs are imposed as pre-agreed damages (e.g., $5,000/day). 8. **Disputes**\ Arise from payment issues, rejected variations, or EOT claims. Resolved through mediation, adjudication (SOPA), arbitration or litigation depending on contract. 9. **Practical Completion**\ Architect certifies the project is substantially complete and usable. Triggers start of the Defects Liability Period (usually 12 months). 10. **Defects Rectification**\ Contractor fixes any defects noted before and during the DLP. Owner can use retention money if the contractor fails to rectify. 11. **Final Account and Completion Certificate**\ Final cost of project tallied. No further claims allowed once this is signed off. *** ## 3. Appointment of Architect: Employer vs Contractor The architect’s role and duties differ based on who appoints them: * **Traditional Contract (e.g. SIA)**\ The **Employer** appoints the architect directly. The architect acts as designer, lead consultant, and impartial contract administrator.\ You certify payments, assess variations, grant EOTs, and issue practical completion. * **Design & Build Contract (e.g. REDAS D\&B)**\ The **Contractor** appoints the architect, usually as a **Consultant Architect** to help fulfil the Employers’ Requirements.\ The architect has no impartial role and acts more as a technical designer. The Employer may separately engage an independent **Employer’s Representative** to oversee compliance. *** ## 4. Design and Build vs Measurement Contract | Feature | Design and Build | Traditional (Measurement or SIA Lump Sum) | | ------------------------- | --------------------------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------- | | **Design Responsibility** | Contractor (based on ERs & Notional Design) | Architect/Consultant | | **Tender Basis** | Based on **Employers’ Requirements** and outline drawings. Contractor submits a **lump sum** offer. | Based on fully detailed drawings and BOQ. Contractor prices **per unit rate**, contract sum varies. | | **Architect’s Role** | Consultant to Contractor (no admin role) | Architect as contract administrator and certifier | | **Speed** | Faster | Slower due to full design first | | **Cost Certainty** | Higher (fixed sum) | Variable (measured quantities) | | **Design Control** | Lower (unless tightly specified) | Higher | *** ## 5. Things to Note for Architects Administering Contracts Whether you’re certifying claims, assessing delays or evaluating defects, here are some must-know practices: * **Timelines and Notices**\ For example, under SIA, EOT claims must be submitted within **14 days** of delay events. Late notices = no entitlement. * **Proper Documentation**\ All variations, approvals, and instructions should be in writing. Meeting minutes, site memos and photographs are your best defence in disputes. * **Impartiality**\ Even if appointed by the Employer, the architect must act fairly under the contract. Biased decisions can be challenged legally. * **Dispute Resolution Path** * **SIA Contract**: Arbitration * **PSSCOC**: Adjudication (via SOPA) * **REDAS**: Mediation > Arbitration * **Common Pitfalls** * Delayed VOs or EOT assessments * Certifying payments without site verification * Issuing instructions without cost/time implications considered *** ## Conclusion Understanding contract administration helps architects safeguard project quality, timelines, and relationships. Whether under a traditional SIA contract or a Design & Build delivery model, your ability to interpret and apply contract terms fairly is essential to your credibility and success. *** #### Recommended References (Singapore) * **SIA Building Contracts 9th Edition** – Singapore Institute of Architects * **PSSCOC Standard Forms** – Building and Construction Authority (BCA) * **REDAS Design & Build Standard Form** – Real Estate Developers' Association of Singapore * **Security of Payment Act (SOPA)** – [https://sopa-bca.gov.sg](https://sopa-bca.gov.sg/) # Tender Process for a Measurement Contract Here's a structured and easy-to-understand article on the stages of a measurement contract tender process, tailored for young architects and architectural graduates in Singapore Measurement contracts remain widely used in both public and private sector construction projects in Singapore, particularly when the design is sufficiently developed to allow for accurate pricing based on **quantities of work**. Unlike lump sum or design-and-build contracts, measurement contracts require detailed documentation and careful preparation. This article outlines the **key stages of the measurement contract tender process**, from early cost planning to tender award. *** ### 1. Preliminary Cost Estimates Before preparing the tender documents, the architect or quantity surveyor (QS) will prepare **preliminary cost estimates** based on early design proposals. This is often called the **Cost Plan** or **Pre-Tender Estimate**. The purpose is to ensure that the proposed design aligns with the project budget and to inform decision-making before going to tender. > **Note:** In government projects under PSSCOC, this is required for internal approvals and tender board submission. *** ### 2. Tender Drawing Preparations Once the design is sufficiently developed, the **tender drawings** are prepared. These include: * Architectural layout and detail drawings * Structural drawings * M\&E drawings Drawings must be coordinated and sufficiently detailed to allow **accurate quantity take-off** and to avoid discrepancies between trades. *** ### 3. Establishing Prime Cost and Provisional Sums Certain elements in the project may not be fully defined at the time of tender. In such cases, the QS includes: * **Prime Cost (PC) Sums** – For supply items (e.g., tiles, sanitary fittings) where the final selection is pending. * **Provisional Sums** – For works not fully scoped (e.g., external works, contingency), to be adjusted later based on actual cost. These allow flexibility during contract administration while maintaining price comparability during tender evaluation. *** ### 4. Specification Preparation A critical component of any tender package is the **Specifications**, which describe the materials, workmanship, and performance standards required. These typically include: * **Architectural Specifications** (e.g., floor finishes, door hardware) * **Performance or Prescriptive Specifications** depending on the approach * References to Singapore Standards (SS), BCA requirements, or proprietary systems * Workmanship clauses and compliance with Green Mark/Buildability Score > **Tip for Architects:** Use **standard specifications frameworks** (e.g. SIA Archspec) to ensure completeness and consistency. *** ### 5. Preparation of Tender Documents All components are compiled into the full tender document, which generally includes: * Instructions to Tenderers * Form of Tender * Conditions of Contract (e.g., SIA or PSSCOC) * Preliminaries * Bill of Quantities (BOQ) * Drawings and Specifications This full package forms the basis on which contractors will submit their prices. *** ### 6. Invitation to Tender (ITT) An **Invitation to Tender (ITT)** is issued to selected pre-qualified contractors, often drawn from an **approved panel** or following a **prequalification exercise**. For public projects, this is published via **GeBIZ** or similar platforms. The ITT specifies: * Closing date and time * Submission format (hardcopy/online) * Tender briefing or site showround date (if any) *** ### 7. Form of Tender This is the legal form the contractor signs to acknowledge: * Their offer is valid for a specific duration (e.g. 90 days) * They agree to the conditions and scope * Their total tendered price (sum of BOQ + PC/Provisional Sums) This form must be signed and submitted as part of the tender submission. *** ### 8. Tender Call The **tender is officially opened** for submissions, often lasting 3 to 6 weeks depending on the scale and complexity of the project. During this period: * Tender queries may be submitted by contractors * Clarifications are issued via **Addenda** (which form part of the contract) * No major changes should be made unless all parties are notified equally *** ### 9. Tender Close At the stated deadline, the tender is **closed** and submissions are collected. In public tenders, the opening is often done in the presence of witnesses to ensure transparency. All received submissions are recorded, including: * Tenderer names * Price * Variations or alternative offers *** ### 10. Tender Interview / Clarifications For shortlisted tenderers, the QS and consultants may conduct **tender interviews** to: * Clarify abnormal rates or lump sum items * Assess technical approach and resourcing * Confirm understanding of scope and timelines This is especially useful for complex projects with high provisional items or multiple interfaces. *** ### 11. Tender Evaluation The evaluation considers more than just the lowest price. It typically includes: * **Price comparison** – BOQ and unit rates * **Compliance check** – Submission completeness, specifications, programme * **Past performance** – Safety record, financial standing, track record * **Buildability and methodology** For government projects, a **Quality Fee Method (QFM)** or **two-envelope system** may be used to assess technical and price proposals separately. *** ### 12. Tender Recommendation & Award After evaluation: * A **Tender Evaluation Report** is prepared by the QS and architect * A recommendation is made to the Employer or Approving Authority * Upon approval, a **Letter of Acceptance (LOA)** is issued to the selected contractor The contract sum is fixed based on the successful tender and the contractor proceeds to mobilise on site. *** ### Additional Considerations * **Prequalification (Optional)**: For larger or specialised works, prequalification ensures only capable contractors are invited. * **Site Showround / Briefing**: Allows contractors to familiarise with the site conditions. * **Addenda / Clarifications**: Any changes or clarifications to the tender are formalised and issued equally to all bidders. *** ### Conclusion Understanding the full tender process for a measurement contract helps architects deliver well-scoped, competitive, and fair construction tenders. The more complete and coordinated the tender package, the fewer the variations and disputes down the line. Architects working closely with the QS and consultants at every stage can ensure a smoother project start and stronger control throughout the construction phase. # Project Management for Young Architects: From Design to Completion Here's a clear and concise article on project management for young architects, covering responsibilities from design through to construction and project completion — with an emphasis on key milestones Being a great architect isn't just about producing beautiful drawings. One of the most important (and often overlooked) parts of your career is **project management** — keeping a project on track from concept to completion. As a young architect, you play a vital role in guiding the project team, coordinating between consultants and contractors, and ensuring your design vision is realised **on time**, **on budget**, and **to specification**. This guide will walk you through what to expect at each project stage, and how to contribute meaningfully. *** ## 1. Design Stage: From Vision to Approvals #### Your Key Roles: * Develop coordinated design drawings in tandem with engineers and consultants * Prepare for and attend various **project meetings and presentations** * Submit design for **authority clearances** (e.g., Design Gateway, Construction Gateway, Completion Gateway) #### Types of Meetings to Attend: * **Client-Consultant Meetings (CCMs)**: Align on design direction, functional requirements, budget. * **Design Reviews**: Present architectural proposals to internal team, client, and stakeholders. * **Technical Coordination Meetings (TCMs)**: Resolve clashes between architectural, structural, and M\&E elements with consultants and/or contractors. #### Milestones to Track: * **Design Freeze/Sign-Off** by client * **Authority Submissions** * **In-Principle Approvals (IPA)** * **Tender Documentation Finalisation** – coordinated drawings, specifications, and BOQ > **Tip:** Design sign-offs must be documented. Avoid major changes after tender call to minimise costly variations later. *** ### 2. Tender Stage: Pricing and Contract Award #### Your Key Roles: * Coordinate tender documentation with QS and consultants * Answer tender queries from contractors * Evaluate technical submissions (with QS on pricing) #### Important Documents: * **Architectural Drawings** – properly coordinated with consultants * **Specifications** – clear descriptions of materials, finishes, and standards * **Addenda** – issued to all tenderers if clarifications are made during tender period #### Milestone: * **Tender Award & LOA Issuance** – Project enters the construction phase *** ### 3. Construction Stage: Managing Progress On Site Now the real action begins. As a young architect, you'll likely take on a **Contract Administrator** or **Project Architect** role. #### Key Responsibilities: * Attend **monthly site meetings** with contractor and consultants * Monitor construction progress and milestone tracking * Respond to **Requests for Information (RFI)** and **Requests for Approval (RFA)** * Review **shop drawings** and **material submissions** * Track **Variation Orders (VOs)** and assess impact * Review **Extension of Time (EOT)** claims (often raised monthly) #### Key Project Management Concepts: **S-Curve (Progress Tracking)** * Graphical representation of cumulative progress vs time * Tracks **early start**, **planned progress**, and **late finish** * Used in monthly meetings to evaluate delays or acceleration **RC Cycle (Reinforced Concrete Cycle)** * Describes time taken for each structural floor slab to be cast * Important for high-rise projects to assess construction efficiency * RC cycle affects scheduling for architectural and M\&E trades **Tracking Logs to Maintain:** * **RFI/RFA Logs** – Ensure timely responses to avoid site delays * **VO Logs** – Keep tabs on design changes and cost implications * **Shop Drawing Logs** – Prevent rework due to outdated drawings * **EOT Logs** – Document reasons, assessments, and approvals of delay claims *** ### 4. Construction Milestones to Watch #### Coordinated Services Drawings (CSDs) Must be approved and resolved before major construction phases: * **Underground Services** – Drain lines, manholes, incoming water/electrical mains * **1st Storey High Level Services** – Soffit M\&E services to coordinate with beam layout * **Typical Floor Services** – Ensure no clash between ducts, conduits, and slabs * **Roof Services** – Water tanks, lightning protection, mechanical exhausts #### Physical Construction Milestones: * **Topping Out / Structural Completion** – End of major concrete works * **Service Turn-On** – Incoming power and water supply activated * **Dry Runs for TOP** – Internal checks before inviting BCA, SCDF, PUB for inspections * **External Works** – Carparks, drain channels, landscape must be completed before TOP * **Application for Temporary Occupation Permit (TOP)** – Key handover milestone > **Why These Matter:** Missing or delaying these milestones means: > > * Delay in TOP and key handover > * Penalties under contract (e.g. Liquidated Damages) > * Frustrated clients and end-users *** ### 5. Completion and Close-Out #### Final Roles: * Conduct defect inspections with client and contractor * Issue **Architect’s Completion Certificate** * Track and coordinate **Defects Rectification** * Assist QS with **Final Account** sign-off *** ### Final Advice for Young Architects * **Take Ownership**: You may not be the most senior in the room, but your diligence sets the tone for the team. * **Know Your Drawings and Site Conditions**: Don’t just rely on the contractor. Visit the site often. * **Document Everything**: Meeting minutes, RFIs, approvals — your best defence against disputes. * **Understand the Milestones**: These aren't just administrative dates. They're contractual obligations. *** ### Conclusion Project management is a crucial skillset for any architect — not just for ensuring the design is built correctly, but also for navigating the legal, contractual, and logistical realities of construction. Learning to manage meetings, track milestones, and coordinate effectively with your team puts you on the path from being a good architect to becoming a reliable project leader. # Common Mistakes Architects Make During Construction Stage (And How to Avoid Them) For young architects involved in project delivery, construction stage is often where everything becomes real — drawings are interpreted, built, and evaluated. Mistakes at this stage can result in costly rectifications or time-consuming delays. Here’s a breakdown of common pitfalls and how to avoid them: *** ## 1. **Blind Approval of Submittals** **What’s the mistake?**\ Approving shop drawings, material samples, and method statements without cross-checking against tender drawings, specifications, or coordination with other trades. **Impact:** * **Cost:** Wrong materials or systems installed that do not meet the design intent. * **Time:** Rework and site instructions needed to rectify, delaying progress. **How to prevent it:** * Develop a **submittal review checklist**: check alignment with tender drawings, specifications, and coordination with other trades. * Loop in relevant consultants during reviews (e.g. M\&E for coordinated drawings). * Always mark up submittals with “Approved with Comments” or "No Exceptions Taken" with disclaimers to protect yourself. The onus is on contractor to comply to tender drawings and specifications regardless. * When in doubt, do not approve and seek your QP's view on the submittal. *** ## 2. **Not Reviewing Combined Services Layouts** **What’s the mistake?**\ Skipping thorough reviews of Integrated Concurrent Engineering (ICE) sessions, Combined Services Drawings (CSD) review, which integrate architectural, structural and M\&E services. **Impact:** * **Cost:** Clash between structure, ceiling heights, and services like ducts or sprinklers may require site rework. * **Time:** Delay in completion due to late clash discovery and need for rework. **How to prevent it:** * Conduct **combined services coordination meetings** with consultants and contractor before installation. * Mark underground structural footing locations, critical service zones and service corridors early in design. * Use BIM or clash detection software when available, like Navisworks. *** ## 3. **Not Reviewing Construction Drawings Post-Tender** **What’s the mistake?**\ Assuming the tender drawings are complete and skipping detailed design development during the construction stage. **Impact:** * **Cost:** Missing details lead to contractor assumptions or disputes. * **Time:** Late RFIs, site queries, or mock-up rejections. **How to prevent it:** * Do a **post-award drawing audit**: identify gaps and ambiguous detailing. * Update and issue **construction issue drawings** in a timely and coordinated manner. * Hold internal QA reviews before releasing drawings. *** ## 4. **Starting Work Without Necessary Approvals** **What’s the mistake?**\ Proceeding with works (e.g., structural elements or site clearance) before receiving approval from authorities or QP endorsements. **Impact:** * **Cost:** Possible stop-work orders and penalties. * **Time:** Project halts until retrospective submissions are cleared. **How to prevent it:** * Maintain a **construction start checklist** tied to approval statuses. * Coordinate with the C\&S, M\&E, and other QPs for endorsements before issuing approval to proceed. * Include authority approval milestones in the construction program. Monthly progress meetings should include tracking for authority clearances. *** ## 5. **Amendment Plans Not Submitted** **What’s the mistake?**\ Failing to submit updated plans to authorities after design changes or value engineering decisions. **Impact:** * **Cost:** Non-compliance can result in rejected TOP/CSC submissions. Rework might be required to tally approved plans. * **Time:** Back-and-forth with authorities during TOP period delays occupation. **How to prevent it:** * Track **all design changes** via an amendment log. * Schedule regular reviews to determine if submission of amendment plans is required. * Communicate clearly with your submission consultant to align timelines. *** ## 6. **Not Visiting the Site Regularly** **What’s the mistake?**\ Relying too much on drawings and reports without physically inspecting progress, workmanship, or site challenges. **Impact:** * **Cost:** Missed quality issues or incorrect installations become permanent. * **Time:** Late identification means more work to undo and redo. **How to prevent it:** * Set a **routine for site inspections** — even once a week can make a difference. * Attend key milestone checks: e.g., rebar inspection, waterproofing works, service mock-ups. * Document site walks with photo reports and issue timely architect's instructions (AIs) when needed. *** ## Final Takeaway: A successful construction phase depends on *proactive involvement*, *structured checks*, and *coordination*. Young architects must go beyond design and become accountable for delivery — because at this stage, *errors cost money and time*. **Build good habits now**: Review carefully, ask questions, walk the site often. That’s how you’ll grow from a drawing architect into a trusted project leader. # Singapore Building Codes & Guides Looking for a summary of the various authority code of practice and guidelines?

In Singapore, there are several contract types based either measurement or lumpsum, build only vs design & build contracts. There are also various institutes in Singapore that your project may be adopting the contracts. This is dependent on the project typology and whether it is a public government or private project. ## **Singapore Institute of Architects (SIA) Form of Building Contracts (**[**Purchase link**](https://sia.org.sg/publications/)**)** 1. SIA Building Contract 2016 (WithoutQuantities) Domestic & International 2. SIA Building Contract 2016 (With Quantities) Domestic & International 3. SIA Building Contract 2016 (Design & Build) Domestic & International 4. SIA Sub-Contract 2016 Domestic & International 5. SIA Minor Works Contract 2012 6. SIA Minor Works Sub-Contract 2019 7.
