In which phase are document systems verification checks carried out?

• A. Design
• B. Acceptance
• C. Construction
• D. Post-Acceptance

Answer: (C)

Document systems verification checks are best performed during the Construction phase because this is when the actual systems are being installed, tested, and wired together, and the supporting documentation is created or updated to reflect what is built. During Construction you verify that as-built drawings, equipment data sheets, sequences of operation, test and commissioning reports, manuals, and warranties match the installed equipment and control logic. This ensures the documentation package is complete and accurate before moving toward handover, reducing delays and rework later in the process.

Design happens before anything is built, so you don’t yet have the installed system or the finalized records to verify. Acceptance occurs after construction when the owner checks performance and documentation as a condition of handover; however, the critical verification of the document set should be completed during Construction to ensure a smooth, timely transition. Post-acceptance would come after handover, when changes or updates might occur, but the verification should already be in place.
