Who is responsible for Construction Phase Facilitate Start-Up of Commissioned Systems?

• A. CxT
• B. Shared
• C. CxA
• D. Contractor

Answer: (A)

During construction, the on-site start-up of commissioned systems is carried out by the Commissioning Technician. This role leads the actual activation, follows the start-up procedures step by step, checks control sequences, coordinates with trades to power up equipment, and records results. The Commissioning Authority provides the plan, defines acceptance criteria, and reviews the outcomes to verify the system meets the design intent, but hands-on start-up tasks are executed by the Commissioning Technician as part of the commissioning team. The contractor supplies and installs equipment, but the day-to-day start-up facilitation is the technician’s responsibility.
