Who is responsible for Construction Phase Cx Schedule Integration?

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

Answer: (A)

Integrating commissioning activities into the construction schedule is led by the CxA. The reason is that the CxA is responsible for planning, coordinating, and verifying the systems’ performance throughout construction, so their work must be aligned with the project timeline. By embedding commissioning tasks—such as equipment start-up, functional performance tests, sequence checks, and training—into the construction schedule, the CxA ensures those activities have the necessary access, resources, and dependencies to be completed before turnover.

This alignment helps prevent delays where testing is rushed at the end or systems remain untested as slab-to-turnover dates approach. The owner provides the overall goals and occupancy targets, and the architect focuses on the design, but the practical integration of Cx activities into the master schedule is driven by the CxA to ensure a smooth, verifiable transition from construction to operation.
