At a minimum, when does the Occupancy and Operations Phase end?

• A. At project closeout
• B. After the warranty period ends
• C. Through the contractual warranty/correction period
• D. Upon final acceptance of all systems

Answer: (C)

The end of the Occupancy and Operations Phase is defined by the contract’s warranty/correction period. Once the building is in use, the commissioning team verifies that systems perform as intended and addresses any defects or performance issues that arise under the contract. This corrective window lasts for the warranty period, so the phase ends at its conclusion. Project closeout or final acceptance are separate milestones and can occur earlier or later, but they don’t establish the minimum endpoint for occupancy operations.
