Who reviews and approves acceptance phase documents?

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

Answer: (B)

Acceptance phase documents are formalized through a joint sign-off by the commissioning authority and the owner (or the owner’s representative). This shared review makes sense because the CxA verifies that testing was performed correctly, that the system meets the specified performance and commissioning criteria, and that all documentation is complete. The owner then confirms that the system fulfills their needs, is ready for operation, and that warranties, O&M manuals, and training meet their expectations. Requiring both parties to approve ensures accountability and that no single party bears the risk of acceptance alone. The vendor can provide documentation, but they are not the approving authority for acceptance, and a sole approval by the on-site technician is insufficient for formal handover.
