In which phase does the CxA review contractor submittals occur?

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

Answer: (B)

Submittal reviews by the CxA happen during the construction phase because that is when contractors provide shop drawings, product data, installation details, and test plans that must align with the project requirements and the commissioning plan. The CxA checks these submittals to confirm that the equipment, control sequences, interfaces with the building automation system, and installation methods will support proper performance and the planned commissioning activities. Catching issues at this stage prevents costly changes later and ensures that what gets installed can be tested and verified as intended. In design, submittals are more about design documents and specifications, not the contractor-provided items the CxA needs to validate; post-acceptance focuses on operating procedures, warranties, and training after the system is installed, not on reviewing contractor submittals.
