Notching Duct for Structural Conflicts

Maximum notch allowed without reinforcement? Engineer-approved detail if it exceeds that?

I'm checking notching duct for structural conflicts at [location]. I found duct section with notch cut to clear beam or structural element. Maximum notch allowed without reinforcement? Engineer-approved detail if it exceeds that?

Stop if

Hold point on notching duct for structural conflicts: I have the location, photo, drawing/detail, and what I checked. Who should verify before this gets cut, drilled, covered, lifted, connected, or signed off?

Watch out

Do not notch structural members. Do not notch or field-cut duct for a beam conflict without approved direction. Do not treat a conflict as a fabrication problem until drawings/details are checked.

Check
