Who prepares the Cx Outline in the Pre-Design Phase?

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

Answer: (B)

The Cx Outline is an early commissioning document that defines how the project will be commissioned, including which systems will be tested, the roles and responsibilities, milestones, and the approach to verification. In the Pre-Design Phase, the Commissioning Authority prepares this outline to establish the commissioning framework before design decisions take shape, ensuring the owner’s requirements and performance criteria guide design choices from the start. This independent perspective helps align the design team with expected testing, acceptance criteria, and coordination processes, setting a solid foundation for the subsequent design and construction stages. While the project manager, architect, and contractor each have important roles, the formal outlining of how commissioning will be carried out is the responsibility of the CxA, who owns the commissioning process.
