Which phase has coordination of the Cx process through the project schedule, Cx plan, and commissioning meetings?

• A. Design
• B. Construction
• C. Acceptance
• D. Post-Acceptance

Answer: (B)

Coordinating the Cx process with the project schedule, Cx plan, and commissioning meetings happens during construction because this is when the building systems are being installed, configured, and prepared for testing. The Cx plan outlines exactly what needs to be tested, in what order, and who is responsible. Linking that plan to the overall project schedule ensures commissioning activities align with installation milestones, submittal reviews, and permit windows, so nothing is tested or handed off before the system is ready. Regular commissioning meetings held during construction bring together the project team, contractors, and the Cx team to review progress, address open items, and confirm readiness for functional tests, enabling a smooth transition toward acceptance. While the design phase is where the plan and tests are defined and the acceptance phase focuses on verification and handover, the actual coordination of Cx activities through schedule, plan, and meetings is most effectively carried out during construction.
