Which activity is explicitly listed as a Trade Contractor responsibility in the commissioning process?

• A. Review the commissioning plan
• B. Correcting identified deficiencies within their scope
• C. Attending selected commissioning meetings
• D. Update design narratives in the BOD to reflect as-built conditions

Answer: (B)

In commissioning, responsibilities are assigned to different players, and trade contractors are specifically accountable for fixing issues that fall within their scope. When deficiencies are identified during testing, a trade contractor must implement corrective actions, adjust installations, re-test to verify the fix, and provide documentation showing that the problem is resolved. This ensures the equipment and systems they installed meet the design intent and performance requirements.

Reviewing the commissioning plan is typically led by the commissioning authority or the project team, not the trade contractor. Attending selected commissioning meetings can happen, but it isn’t an explicit primary duty of a trade contractor. Updating design narratives in the Basis of Design to reflect as-built conditions is usually handled by the design team or commissioning authority, not the trade contractor, so it isn’t their explicit responsibility.
