Stop if

Hold point on tdf flange corner gap: 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

Do not force a gapped corner together with hardware. Do not treat mastic as the primary fix for a bad flange fit. Do not assume random fasteners are the normal field fix.
