Who is responsible for document control during the Pre-Design Phase?

• A. CxA
• B. Project Manager
• C. Architect
• D. Contractor

Answer: (A)

Document control during the Pre-Design Phase is handled by the Commissioning Authority. At this stage the CxA sets up how commissioning-related documents will be created, versioned, distributed, and archived, and ensures they align with the Owner’s Project Requirements and Basis of Design from the outset. The CxA maintains the master set of commissioning documents, tracks changes, and coordinates with designers and contractors to keep information consistent and traceable. While the project manager, architect, and contractor produce their own documents, the independent control and integrity of the commissioning records rest with the CxA, ensuring the owner’s goals and system performance criteria can be verified throughout the project.
