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

• A. CxA
• B. Shared
• C. Owner
• D. End user

Answer: (B)

The 11th-month Post-Acceptance Review is a collaborative activity between the commissioning authority and the building owner. The CxA leads the process by collecting performance data, verifying that corrective actions have been completed, and coordinating with contractors to confirm systems operate as intended under real occupancy conditions. The owner supports by providing access, resources, and confirmation that warranty items are addressed and that the building continues to meet the design intent in operation and maintenance. The end user offers practical feedback on day-to-day use, but the formal review and warranty follow-up are shared responsibilities, requiring both parties to work together to close any outstanding items before the warranty period expires.
