Who is responsible for Construction Phase Review Submittals?

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

Answer: (A)

During construction phase commissioning, the person responsible for reviewing submittals is the Commissioning Authority. They verify that submittals such as shop drawings, product data, equipment schedules, sequences of operation, and operation and maintenance manuals reflect the design intent and meet the owner’s project requirements. The contractor submits these documents, but the CxA evaluates them, checks for consistency with the design and the commissioning plan, and coordinates with the design team to identify and resolve any issues before turnover. A CxT may assist the CxA, but the primary responsibility for construction phase review of submittals lies with the CxA, ensuring that systems will operate correctly and integrate properly within the project. The owner’s role is to approve the contract and participate in key decisions, but the actual review work during construction aligns with the CxA’s commissioning responsibilities.
