Pre-TAB walk found a problem before the balance crew starts. What now?
Use the pre-TAB problem as a punch item, not a guessing session. Identify whether the issue is access, labels, dampers, disconnected flex, wrong diffuser, missing grille, closed fire/smoke damper, insulation, or startup readiness.
Turn the pre-TAB issue into a clean punch item with room, tag, photo, and requested direction.
