Seismic Bracing Spacing and Angles

Confirm spacing, angle, and attachment point from detail. Need both longitudinal and transverse?

I'm checking seismic bracing spacing and angles at [location]. I found cables or rigid struts at angles connecting duct to structure. Confirm spacing, angle, and attachment point from detail. Need both longitudinal and transverse?

Stop if

Hold point on seismic bracing spacing and angles: 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 without engineered details. Don't guess spacing or angle. Don't attach to unrated structure.

Check
