Do not move seismic/sway bracing casually: using field-made brace not allowed by spec.
High-risk starter answer - stop before you change, move, drill, or attach anything tied to seismic bracing, sway control, structural support, crane work, or rigging. Verify the approved detail and the qualified person's direction before acting. Field-made brace assemblies can be rejected if they are not in the approved detail or submittal.
Ask whenever brace location, anchor, angle, attachment, or clearance changes.
Watch out
Do not modify or copy bracing/rigging from another area just because it looks similar.
Check
Identify whether you are looking at a hanger, brace, restraint, anchor, insert, structural member, rigging gear, or crane/lift-day zone.
Verify whether field-fabricated bracing is allowed before building it.
Steps
Identify whether it is a hanger, brace, restraint, or structural attachment.
Check seismic/coordination drawing if available.
Photograph full load path from duct to structure.
Focus on the actual issue: using field-made brace not allowed by spec.
Photograph or mark the condition if someone else needs to approve it.
Say this to your foreman
In Seismic Bracing, Sway Control & Structural Coordination, I'm looking at: Using field-made brace not allowed by spec. What should I verify before I cut, drill, seal, cover, move, or install?
