What are the four main items regarding construction commissioning during the acceptance phase?

• A. Perform FPTs; Verify TAB; Training O&M staff; Cx final report
• B. Perform FPTs; Training O&M staff; Cx final report; Verify TAB
• C. Verify TAB; Cx final report; Perform FPTs; Training O&M staff
• D. Execute and document SVCs; Cx final report; Equipment start-ups; Verify TAB

Answer: (A)

The acceptance phase focuses on proving that the building’s systems perform as intended, the operation team is prepared to run them, and there is clear documentation of what was tested. The four main items are: performing functional performance tests to demonstrate that equipment and systems operate to design criteria under real conditions; verifying TAB to ensure air and water flows are properly balanced for comfort, safety, and efficiency; training the O&M staff so they can operate and maintain the systems correctly after handover; and producing the Cx final report that documents test results, any deficiencies and remediation, warranty information, and recommendations. This combination ensures verifiable performance, proper system balance, and a ready-to-operate handover package. Other options mix in items like start-ups or early-stage verifications that belong earlier in the process or reorder elements in a way that doesn’t align with the acceptance-oriented deliverables.
