Turnover & closeout
Functional performance test
A functional performance test is the commissioning step where a system is run against a written test script through its intended operating conditions (normal, off-normal, and failure modes), with each expected response recorded as pass or fail. It proves the whole system works as a system, not just that individual components energize. A test only counts when the equipment has been installed, started up, and pre-functionally checked first.

How it shows up on site
The commissioning agent, controls contractor, and relevant trade run the script together: force a call for heating or cooling, simulate a loss of power, trip a safety, and confirm the sequence does what the design says. Air balance reports, control setpoints, and alarm responses all get exercised here rather than assumed.
What proves it
The completed test script is the evidence: every line marked pass or fail, with the date, who witnessed it, and a note on any deficiency. Failed lines drive corrections that get retested, and the closed-out scripts, photos of the tested equipment, and final results become part of the commissioning record delivered at turnover.
Guides that use it
- How to inspect a fire alarm systemObserve and document fire alarm work at rough-in and final (devices, circuits, coverage and mounting), knowing the licensed tech and AHJ run the required acceptance test.
- How to inspect a fire sprinkler systemObserve and document sprinkler rough-in and final (layout, hangers, heads and hydro test) while the licensed contractor and AHJ run the required hydrostatic and acceptance tests.
- How to run commissioning at closeoutSupport the commissioning agent as they verify systems perform as designed: schedule the tests, get systems ready, and document the functional performance tests and issues.
