Pre-TAB Walk Checklist

Use this before TAB/balance starts so obvious install problems do not turn into startup drama.

TAB is scheduled soon, systems are being started, or a foreman asks for a final airflow/access readiness walk.

Do not wait for TAB to discover blocked dampers, missing labels, kinked flex, or inaccessible VAVs.
Do not randomly adjust dampers without TAB/foreman direction.
Do not close ceiling over unknown access points.

Walk by system and room. Make a punch list before TAB finds it for you.
Confirm every diffuser, grille, register, VAV, damper, coil, and access panel is installed, tagged, and reachable.
Check flex for kinks, sag, excess length, crushed liner, and bad support.
Check branch takeoffs, taps, transitions, and fittings for obvious restrictions or wrong orientation.
Check damper handles and test/balance access are not hidden by ceiling, insulation, or walls.
Check visible joints, collars, boots, access doors, and openings for leakage or missing seal.
Record not-ready items by room/grid/system with a wide photo and close-up.

TAB starts [date]. Do you want me to run this pre-TAB walk and send a room-by-room punch list before they arrive?
