During construction, which activity includes verifying BAS install and start-up?

• A. TAB HVAC systems
• B. Coordination efforts
• C. Equipment and systems start-ups
• D. Review submittals

Answer: (C)

Equipment and systems start-ups focus on powering the systems and confirming they operate correctly, including the Building Automation System (BAS) installations and startup sequences. This phase verifies that BAS hardware and software are properly installed, that controllers communicate with equipment, that control sequences are correct, and that sensors and actuators respond to BAS commands, followed by functional tests of the systems. TAB centers on testing, adjusting, and balancing airflow, which is a separate performance verification step, while reviewing submittals and coordination efforts are preparatory or coordination activities rather than on-site startup verification.
