During the Construction phase, which task is performed as part of Commissioning?

• A. TAB agency completes and documents test and balance work.
• B. Finish lighting retrofits only.
• C. Owner training only.
• D. Final warranty review only.

Answer: (A)

During construction, Commissioning centers on verifying system performance through testing, adjusting, and balancing. The TAB (testing, adjusting, and balancing) agency completes and documents the test and balance work, ensuring HVAC systems meet design intent and operating requirements. They perform measurements of airflow, pressures, temperatures, and control sequences, adjust setpoints and damper positions as needed, and compile a TAB report that captures results and any deficiencies for resolution before turnover. This makes TAB documentation essential for a clean handover and reliable operation. Other activities listed—finishing lighting retrofits, owner training, or a final warranty review—are typically broader project tasks or actions that occur at different stages and are not the primary commissioning work performed by the TAB process during construction.
