The Commissioning Agent: What They Do, Why Projects Need One, and How They Integrate with Construction
The commissioning agent (CxA) is the specialized consultant who verifies that building systems perform as designed. Engaged from design through post-occupancy, the CxA reviews design for commissioning needs, witnesses testing during construction, verifies functional performance before occupancy, and confirms systems work together. Good commissioning prevents the operational problems that plague buildings not commissioned well. Understanding the CxA role helps GCs integrate commissioning effectively into project delivery.
