Which activity is used to confirm system performance during construction and commissioning?

• A. Review submittals and plans
• B. Observe and document equipment start-ups only
• C. Carry out and document system verification checks
• D. Prepare as-built drawings only

Answer: (C)

The main idea is verifying that the system operates according to design through formal checks and documentation. During construction and commissioning you carry out and document system verification checks, following approved test procedures to exercise equipment, control sequences, setpoints, interlocks, and alarms under normal and fault conditions. This process provides objective evidence that the system meets performance criteria and will operate reliably in the field, capturing results, deviations, and acceptance when criteria are satisfied. Submittals and plans review is a planning/verification activity that happens earlier and doesn’t prove actual in-field performance. Observing and documenting equipment start-ups is useful but only captures initial operation, not the full range of performance, sequencing, and interlock validation. Preparing as-built drawings records the final documented state, not the verification of performance. Therefore, performing and documenting system verification checks best confirms system performance during construction and commissioning.
