What do I do when a 45-degree offset travel piece hits a seismic brace or cable?

Seismic Bracing, Sway Control & Structural Coordination⚠️ CHECK BEFORE YOU FIXField answer expansion

📖 Verified core answer

Do not cut, bend, or tension someone else’s seismic brace. Rework your duct path or coordinate the brace conflict with the foreman.

Open in Field Rescue Open category

Field verification checklist

Identify whose seismic brace or cable it is.
Check whether it is under tension or connected to equipment.
Do not loosen or move it without direction.
Lay out an alternate offset path around the brace.
Document the conflict for coordination if clearance is tight.

Ask foreman

Our 45 offset travel piece is hitting a seismic brace at [location]. I did not touch the brace. I can adjust our elbow path or hold for coordination. What do you want?

Text to foreman

Route options

A Correct it only if the fix is within your assignment and approved method.

B Hold and document if it affects pressure class, listed assembly, material spec, support load path, fire barrier, equipment, TAB, or another trade.

C Bring the foreman/detailer the location, what you checked, and what decision you need before sealing, testing, cover, or startup.

Do not do this

Do not cut, bend, loosen, or pull on a seismic cable to make duct fit.

Why this matters

Altering seismic bracing can create a structural safety issue and fail inspection.

Final verification

Use this as field training guidance. Final direction still comes from the foreman, approved drawings, project specs, manufacturer installation instructions, employer safety policy, pressure/material schedule, and AHJ/code requirements.
