Who is responsible for Post-Acceptance Phase Direct 11th Month Review?

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

Answer: (C)

In commissioning practice, the Post-Acceptance Phase Direct 11th Month Review is led by the CxA. The Commissioning Authority is responsible for verifying that the building continues to meet design intent after occupancy, during the warranty period, and for closing out the commissioning process with the owner. This review typically covers open warranty issues, performance verification, and ensuring that operation and maintenance manuals, training, and preventive maintenance plans are in place and functioning. The internal team can provide data and support, and a CxT may carry out field tasks under direction, but the formal, owner-facing review and sign-off rests with the CxA.
