Who is responsible for Construction Phase Document Control?

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

Answer: (C)

During construction, the person who coordinates and controls all commissioning documentation acts as the central owner of the project’s records. The Commissioning Authority is responsible for collecting, organizing, reviewing, and archiving all documentation related to commissioning activities—such as test plans and procedures, test results, vibration of deficiencies, punch lists, field observations, equipment submittals, and the final commissioning report. This role ensures a consistent, traceable record that reflects the design intent and confirms that systems meet the required performance before occupancy.

The owner and contractor generate and provide documents, but the CxA consolidates them and tracks their status, handles the documentation flow, and verifies that items are closed out. Having a single point of control prevents fragmented records and maintains objectivity in verification, which is essential for acceptance and handover. Shared responsibility can lead to confusion and gaps, whereas the CxA’s established process keeps the documentation cohesive and aligned with project goals.
