Who is responsible for Construction Phase Document Control?

• A. CxT
• B. Shared
• C. CxA
• D. CxP

Answer: (C)

Document control during construction is handled by the Commissioning Authority because they own the commissioning process and are responsible for creating, maintaining, and verifying the records that prove the systems were tested and meet the owner’s requirements. The CxA prepares and maintains the Construction Phase Plan, test protocols, test results, logs, punch lists, and the formal commissioning report, ensuring all field observations, submittals, and tests are properly documented and tied to the design intent for turnover. The on-site technician focuses on carrying out tests and collecting data, while the Commissioning Project Manager coordinates activities across trades; they do not establish and manage the entire documentation set. Having a single responsible party avoids gaps and keeps documentation consistent and auditable.
