A rigid brace should not pin or rub another trade line. Stop, clear the conflict, and revise the brace angle/attachment by approved direction.

Open in Field Rescue Open category

Field verification checklist

Identify the other trade line and its risk level.
Look for hard contact, rub marks, or pipe deflection.
Check whether the brace can pivot on the duct clamp.
Keep required clearance per approved coordination/detail.
Notify foreman before altering seismic layout.

Ask foreman

Our rigid seismic brace at [location] is hard against [other trade line]. I stopped tightening it. Do you want the brace angle/anchor revised and the other trade notified?

Route options

AMake the field correction only if it is within your assignment and the approved method.

BHold and document the condition if the fix affects support load path, structural steel, seismic restraint, life safety, another trade, or inspection.

CBring the foreman/detailer the location, what you checked, and what decision you need before loading, cover, startup, or rework.

Do not do this

Do not let a seismic brace use another trade pipe, conduit, or cable tray as a bumper.

Why this matters

A brace that rubs another system can damage critical utilities and fail seismic/coordination 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, structural/seismic detail, and AHJ/code requirements.
