Who is responsible for Acceptance Phase Direct Re-Testing?

• A. CxT
• B. CxA
• C. Internal Team
• D. Shared

Answer: (B)

Direct re-testing in the Acceptance Phase is the Commissioning Authority’s responsibility. The CxA is the one who plans the acceptance activities, approves the test procedures, and ensures that any deficiencies found during acceptance are corrected and re-tested to confirm the fixes actually meet the Owners Project Requirements and the design intent. The CxA oversees the verification process, maintains the test evidence, and signs off when criteria are satisfied. While the actual hands-on testing may be performed by the internal team or a CxT under supervision, the accountability for acceptance re-testing rests with the CxA as the owner’s representative and coordinator of the commissioning process.
