Who handles direct re-testing during the Acceptance Phase?

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

Answer: (D)

In the Acceptance Phase, the Commissioning Authority is the one who directly executes retests. They oversee the owner’s acceptance testing, verify that corrective actions have been completed, and re-run tests to prove the system now meets the required performance and the project’s acceptance criteria. The CxA maintains objectivity, documents the results, and prepares the formal acceptance package when the system passes. The vendor can support with data and test evidence, but the direct testing and validation of retests fall under the CxA’s responsibility to ensure a proper, independent closeout.
