Commissioning report
Also called: Cx report, final commissioning report
A commissioning report is the document the commissioning agent issues at the end of the commissioning process, summarizing the systems tested, the results of the pre-functional checks and functional performance tests, the issues found, and how each was corrected and retested. It is the paper trail that shows the building's systems were verified to perform, not just installed. Its required contents and format follow the commissioning plan and the owner's project requirements.
Why it matters
The report is the owner's proof that commissioning actually happened and that the systems responded the way the design intended. It also flags any issues deferred to seasonal testing or to the warranty period, so the owner knows what is still open. Without it, the owner has equipment they were told works but no record of it being tested.
What proves it
The report is built from the underlying records — completed pre-functional checklists, functional test scripts marked pass or fail, and the corrections that closed each failure. When those are captured cleanly during testing, with photos of the tested equipment, the report is a straightforward summary rather than a reconstruction, and it slots into the turnover package the owner receives.
