TinnerFlow™3rd YearSeismic / Trade ConflictsRED · Stop and get direction
A rigid brace should not pin or rub another trade line. Stop, clear the conflict, and revise the brace angle/attachment by approved direction.
Metal-to-metal contact between a seismic brace and a high-consequence line is not acceptable field “clearance.” It can rub, wear, and damage the other system.
Hold the brace, identify the affected trade, and coordinate a revised brace angle, clamp location, anchor point, or route that keeps the brace independent of other utilities.
Do not let a seismic brace use another trade pipe, conduit, or cable tray as a bumper.
A brace that rubs another system can damage critical utilities and fail seismic/coordination inspection.
Final direction still comes from approved drawings, specs, manufacturer instructions, employer policy, foreman/detailer direction, structural/seismic details, and AHJ/code requirements.
