Who is responsible for implementing re-testing during the Acceptance Phase?

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

Answer: (A)

Re-testing during the Acceptance Phase is a shared task because it combines execution and verification. The party installing and testing the systems (the vendor/contractor) runs the re-tests, implements any corrective actions, and provides the evidence of those tests. At the same time, the commissioning authority coordinates the plan, reviews the results, ensures the test procedures align with the acceptance criteria, and documents the outcomes for handover. This collaboration ensures tests are performed properly, results are independent and verifiable, and any remaining issues are clearly addressed before occupancy. Relying on just one party would either place the burden solely on those who implement the work or leave the verification and documentation without proper oversight. The commissioning team, including the CxA and the broader CxT, shares responsibility to ensure a thorough, traceable acceptance process.
