Who is responsible for Construction Phase Track RFIs/COs/SIs?

• A. CxT
• B. CxA
• C. Shared
• D. CxP

Answer: (A)

During construction, day-to-day field questions and changes—such as RFIs, Change Orders, and Site/Special Instructions—are managed by the Construction Phase Team. This team is responsible for on-site coordination, documenting issues, tracking responses, and ensuring items are resolved before closeout. The commissioning authority (CxA) oversees the commissioning scope, verifies that responses align with the design intent, and witnesses tests, but the actual tracking of RFIs/COs/SIs sits with the Construction Phase Team. The program-level owner (CxP) sets the overall commissioning program, not the day-to-day tracking. So the Construction Phase Team is the best answer because this role specifically handles the construction-phase tracking and administration of those items.
