Who is responsible for Construction Phase Pre-TAB Report Review?

• A. Architect
• B. Shared
• C. Contractor
• D. CxA

Answer: (D)

The key idea is that the Commissioning Authority serves as the independent reviewer of testing and balancing readiness during construction. For the Construction Phase Pre-TAB, the CxA reviews the pre-TAB documentation to confirm it reflects the design intent, that test procedures are appropriate, and that equipment controls and sequences are correctly configured. The CxA also ensures any issues found are properly documented with corrective actions and that these actions are completed before moving into TAB. The contractor is responsible for performing the tests and generating the report, but the critical verification and acceptance decisions come from the CxA to ensure the owner’s requirements are met. The architect provides design information but does not take on this independent verification role.
