Movement clearance at expansion/flexible connector not left
Do not move seismic/sway bracing casually: not leaving movement clearance at expansion/flexible connector.
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. Do not brace a flexible connector, expansion point, or movement joint in a way that defeats its movement.
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.
Confirm where movement is supposed to happen before adding restraint.
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: not leaving movement clearance at expansion/flexible connector.
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: Movement clearance at expansion/flexible connector not left. What should I verify before I cut, drill, seal, cover, move, or install?
