The _____ _____ forms the core of the final commissioning report.

• A. The Cx Plan
• B. OPR
• C. Basis of Design
• D. Commissioning plan

Answer: (D)

The main idea being tested is what organizes and anchors the entire final commissioning report. The Commissioning Plan defines how verification will be done—scope, sequence, responsibilities, and the acceptance criteria for each system. Because the final report records results, deviations, and resolutions, it is built around that plan. It provides the backbone that links the tests performed to the objectives and criteria established at the start, making the report coherent and traceable.

Inputs like the Owner’s Project Requirements and the Basis of Design guide what needs to be achieved and how the design intends to meet it, but they describe intent and goals rather than the verification process itself. The formal term used for the document that drives and structures the testing and verification is Commissioning Plan, not just an informal “Cx Plan,” which is why this option is considered the core reference for the final report.
