Which role is responsible for approving FPT summaries during the Acceptance Phase?

• A. CxA
• B. Vendor
• C. Shared
• D. CxT

Answer: (A)

The key idea here is who signs off on the tests that prove the building’s functions perform as intended during the Acceptance Phase. The person responsible for validating that the Functional Performance Test findings are complete, accurate, and meet the project requirements is the Commissioning Authority. This role oversees the testing process, reviews test results, ensures all issues are resolved, and grants formal approval of the FPT summaries so the owner can accept the systems. The vendor can conduct the tests and submit results, but the official approval rests with the CxA, who acts as the owner’s independent verifier of the commissioning process. The other roles aren’t the standard approving authority for acceptance documentation in this phase, because they don’t carry the same responsibility for verifying and certifying that the system performance meets the contract and design intent.
