Which action is included in the Architect and Engineers (Designers) responsibilities regarding CxA comments?

• A. Respond to or incorporate CxA comments on construction submittals and O&M manuals
• B. Perform tests
• C. Execute construction startup tasks
• D. Provide required documentation for system manuals

Answer: (A)

The action being tested is that designers must address the Commissioning Authority’s feedback by responding to or incorporating CxA comments on construction submittals and operation and maintenance manuals. This is essential because the CxA reviews submittals to verify they support the project’s commissioning plan and design intent. By responding to comments and updating drawings, specifications, sequences, and the O&M manuals accordingly, the design team helps ensure the building will operate as intended and that the owner’s requirements are met. Tests and startup tasks are typically carried out by the commissioning team or contractors, not the designers in response to comments. Providing system manuals is a deliverable, but the specific action tied to CxA comments is to address and integrate those comments into the submittals and O&M documentation.
