Who is accountable for developing the Cx scope during the Pre-Design Phase?

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

Answer: (C)

In the Pre-Design phase, the responsibility for developing the Cx scope falls to the Commissioning Authority. The CxA is tasked with defining what will be commissioned, how it will be tested, what acceptance criteria will be used, and what documentation and deliverables are needed to verify performance. They use the Owner’s Project Requirements and the Basis of Design to outline which systems and sequences of operations will be verified, what tests will be performed, and how the commissioning process will be integrated into the project schedule. This early scoping ensures the owner’s performance goals guide design and construction from the start and provides a clear plan for ongoing commissioning activities. While the project manager coordinates overall progress, the architect focuses on design, and the contractor handles installation, the CxA is the one responsible for shaping the commissioning scope itself.
