Who is responsible for performing design reviews during the Design Phase?

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

Answer: (A)

During the Design Phase, the Commissioning Authority leads the design reviews. The CxA checks design documents to ensure they reflect the owner’s project requirements and the commissioning plan, focusing on how the system will be operated, controlled, and tested. They verify that performance criteria, sequences of operation, control strategies, energy targets, and testing requirements are clearly defined and verifiable in the design. This early scrutiny helps catch issues that would hinder successful startup and verification later, ensuring the design is ready for commissioning and meets measurable performance goals. The Architect develops the design, the Project Manager guides the process, and the Contractor implements it, but the formal design reviews in this phase are the responsibility of the CxA.
