What are the six main items regarding construction commissioning during the construction phase?

• A. Develop Cx scope; Review contractor submittals; Coordinate Cx process w/schedules & meetings; Execute and document SVCs; Equipment start-ups; TAB completes work
• B. Develop Cx scope; Review O&M manuals
• C. Review contractor submittals; Coordinate Cx process; Training O&M staff; Cx final report
• D. Equipment start-ups; TAB completes work; Start-up and testing; Documentation

Answer: (A)

During the construction phase, the commissioning effort centers on establishing a clear scope and actively validating that what gets installed meets the design intent. The six main activities are: first, develop the Cx scope so you know exactly which systems, performance criteria, and tests are in play; second, review contractor submittals to ensure equipment and controls align with the Cx plan and won’t hinder performance; third, coordinate the Cx process with project schedules and meetings so verification activities are integrated with installation milestones; fourth, execute and document System Verification Checks to prove each system operates and meets design criteria; fifth, oversee equipment start-ups to bring systems online and verify basic operation; and sixth, complete the TAB (Testing, Adjusting, and Balancing) work to ensure proper airflow, hydraulics, and overall system balance. These steps together establish verifiable performance readiness during construction and set the stage for final commissioning.
