Which statement best describes the role of the CxA in BCxP?

• A. Manages construction contracts and procurement.
• B. Designs the building systems.
• C. Independently verifies and documents system performance.
• D. Performs only energy modeling.

Answer: (C)

The main role of the CxA in BCxP is to independently verify and document that the building’s systems perform as intended and meet the owner’s requirements. This involves planning and conducting the commissioning process, including creating and following a commissioning plan, reviewing design intent and the Basis of Design, coordinating tests, and performing functional performance tests and sequence-of-operations checks. The CxA collects and documents results, verifies that systems start up correctly, interlocks and controls operate properly, and that performance meets the Owner’s Project Requirements, design intent, and design documents. Throughout construction and into occupancy, the CxA stays objective and focused on verification and documentation, rather than designing systems, managing procurement, or only doing energy modeling.
