Which document defines contractor responsibilities for commissioning?

• A. Write commissioning specifications defining contractor responsibilities
• B. Establish the project schedule
• C. Review design to accommodate commissioning
• D. Develop the scope of commissioning

Answer: (A)

Focusing the contractor’s duties through the commissioning specifications is where contractor responsibilities for commissioning are defined. These specifications are part of the contract documents and spell out exactly what the contractor must perform during commissioning, including test procedures, readiness criteria, data submission, documentation, and training, along with the acceptance criteria. They translate the owner's requirements into concrete actions and accountability, ensuring everyone knows who does what and how success is verified. The project schedule merely addresses timing, not duties. Reviewing design to accommodate commissioning is about ensuring the design can be commissioned, not detailing contractor responsibilities. Developing the scope of commissioning defines what will be commissioned, not the specific duties during the actual commissioning activities.
