What is the prime contractor's responsibility towards subcontractors in the A201 framework?

• A. The Owner handles subcontractor supervision directly.
• B. Subcontractors are independent and not coordinated.
• C. Architect directly manages subcontractor performance.
• D. The prime contractor coordinates, supervises, and ensures compliance of all subcontractors.

Answer: (D)

In AIA A201, the prime contractor is the central coordinator of the construction process. Their responsibility is to coordinate, supervise, and ensure the compliance of all subcontractors with the contract documents, the project schedule, safety requirements, and quality standards. This means the prime contractor must manage how subcontractors work together, align their activities with the architect’s design intent, and ensure that each subcontractor’s performance meets the contract’s terms.

The owner does not directly supervise subcontractors, and the architect’s role is to administer the contract and observe performance rather than manage subcontractors on a daily basis. Subcontractors are not independent of the prime contractor’s authority; they operate under the prime contractor’s direction and are bound to the contract documents through that relationship.

So the best answer reflects that the prime contractor coordinates, supervises, and ensures compliance of all subcontractors.
