Apprentice question
Stop and ask
Stop. Get direction before you touch it.
Do not drill a marked no-drill post-tension slab. Stop the hanger layout and use approved structural direction, GPR, or an engineered alternate support path.
['A post-tension no-drill zone is not a normal hanger layout problem. It means the structure may contain stressed cables that cannot be nicked, cut, or guessed around.', 'Hold the drill, mark the location, and bring the foreman the bay, hanger load, and conflict. The likely recovery is a GPR-scanned anchor path, a shifted approved support point, beam/column attachment, or an engineered bridging strut/header system.']
