Which activity is part of the Architect and Engineers (Designers) responsibilities?

• A. Review the commissioning plan
• B. Update design narratives in the BOD to reflect as-built conditions
• C. Provide input into commissioning plan for CxA's review and approval
• D. Attend selected commissioning meetings

Answer: (B)

Updating design narratives in the Basis of Design to reflect as-built conditions is something designers do to keep the project documentation accurate. As construction progresses, changes often occur from what was originally planned. The Basis of Design captures the design intent, criteria, and equipment selections, so when actual conditions differ, the design narratives must be revised to match what was built. This ensures that operation, maintenance, and future modifications are based on the true installed system, and it provides a reliable reference for commissioning activities and facilities management. The other tasks—reviewing or contributing to the commissioning plan and attending commissioning meetings—are actions typically led or coordinated by the commissioning authority and the project team rather than the designers.
