Overnight Tie-In Was Connected but Airflow and Controls Were Not Verified
Do not treat the area as complete because the sheet metal is connected. Confirm that the designated startup, controls, TAB, commissioning, or operations party verifies equipment status, damper and actuator response, airflow path, alarms, temporary conditions, and the affected occupied zones.
The overnight tie-in is physically complete, but airflow and controls have not been functionally checked. I verified the duct, access, dampers, and temporary covers. Who is completing the startup verification before this area reopens?
Watch out
Do not adjust controls, bypass alarms, or declare balanced airflow outside your assigned scope.
Check
Confirm all temporary caps, blocks, filters, covers, and isolation devices are removed or in the approved position.
Check that access doors, dampers, sensors, tubing, and controls disturbed by the tie-in are restored.
Document unusual noise, pressure, airflow, temperature, or alarm conditions.
Record who accepted the system for reopening.
