During the design phase of the commissioning process, the CxA verifies the BOD with the _____?

• A. OPR
• B. Construction Documents
• C. Issues Log
• D. Commissioning Plan

Answer: (A)

The important idea here is that the Basis of Design should directly reflect what the Owner’s Project Requirements demand. In the design phase, the CxA checks that the Basis of Design translates the OPR into concrete design criteria, performance targets, equipment choices, and system concepts, so the design decisions will actually meet the owner’s needs. Verifying alignment between the BOD and the OPR creates a traceable link from owner expectations to design intent and, later, to commissioning tests and performance verification. Construction Documents implement the BOD, but they’re not the instrument used to verify that the BOD matches the OPR. The Issues Log and the Commissioning Plan serve other purposes—tracking design/installation problems and outlining the CxA’s commissioning approach, respectively.
