# Parties Involved
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**
