Stop if

Hold point on ductwork in high-rise buildings: I have the location, photo, drawing/detail, and what was checked. Who should verify before this gets cut, covered, lifted, sealed, energized, or signed off?

Watch out

Don't install high-rise duct without understanding shaft requirements. Don't ignore floor isolation.

Check
