Which role is responsible for Review Submittals during the Construction Phase?

• A. Contractor
• B. Owner
• C. CxA
• D. CxT

Answer: (C)

The key idea is that the Commissioning Authority oversees how systems will be commissioned, which includes verifying that submittals align with the project’s commissioning plan and owner requirements. Submittals—such as product data, shop drawings, and samples—are reviewed not just for constructability, but to ensure they support the intended performance, control sequences, and verification tests that the CxA will rely on during commissioning. This early review helps catch design gaps, compatibility issues with controls, and startup requirements before installation proceeds, reducing rework and ensuring smooth validation later in the project. The Commissioning Technician is typically a support role that assists the CxA with on-site data collection and tasks but does not own the formal submittal review for commissioning. The Contractor submits submittals and the Owner/design team may review them for constructability or compliance, but the formal review to ensure everything supports commissioning activities falls under the Commissioning Authority.
