During Construction Commissioning (Planning), which activity is performed?

• A. Carry out a survey to gather and document needed information
• B. Review system operation and control sequences in detail
• C. The owner selects the commissioning authority
• D. Prepare commissioning plan

Answer: (D)

Planning in Construction Commissioning focuses on establishing how the work will be carried out, documented, and verified, and that is done by preparing the commissioning plan. This plan defines the overall approach, scope, responsibilities, schedule, required resources, testing and acceptance criteria, documentation flow, and the sequence of commissioning tasks. It provides the framework that guides all later activities—field verification, functional testing, system start-up, and occupancy readiness—and aligns owner expectations with design and construction teams.

While gathering information from surveys can inform the plan, and detailed review of system operation and control sequences is important, those activities occur as part of executing and refining the commissioning process, not as the primary planning deliverable. Similarly, the owner selecting the commissioning authority is an early project decision, but it isn’t the planning activity within the Construction Commissioning phase.
