Who is responsible for reviewing Cx specifications during the Design Phase?

• A. Project Manager
• B. CxA
• C. Architect
• D. Contractor

Answer: (B)

The key idea is that commissioning requirements are owned and verified by the person who leads the commissioning process. During the Design Phase, the CxA reviews the Cx specifications to ensure they accurately reflect the owner’s project requirements and design intent, and that they are clear, complete, measurable, and testable. This early review helps confirm that the sequences of operation, performance criteria, and acceptance tests are properly defined before construction begins, setting up a smooth path for commissioning later.

The Project Manager coordinates schedule, budget, and overall project delivery, but does not specialize in verifying the technical content of commissioning specifications. The Architect leads the design solutions and documentation, and while they may provide input on design criteria, the formal review of Cx specifications for commissioning is the CxA’s responsibility. The Contractor focuses on construction execution and conformance with the design, rather than independently validating the commissioning requirements.
