Building Systems Commissioning becomes involved at what stage of the project?

• A. During schematic design
• B. Near completion of construction
• C. After occupancy
• D. During construction documents

Answer: (B)

Building Systems Commissioning is about proving that the installed systems operate as intended, which requires actually testing and tuning equipment, controls, and sequences. That can’t happen until the systems are in place and wired up, so the commissioning effort is tied to the late construction phase—near completion of construction—when startup, functional tests, and final adjustments can be performed before occupancy. If you try to commission during the early design stages, nothing has been installed to test. Waiting until after occupants are using the building makes it harder to fix issues and optimize performance. So, near completion of construction is the most practical and effective time to involve commissioning.
