Exterior Duct Expansion Joint Is Installed at the Wrong Location
Verify the approved expansion-joint location, orientation, movement direction, support arrangement, and adjoining fixed or guided points before connecting the run.
The expansion joint is installed one bay from the detail location and is already offset before the run is complete. I checked the supports and fixed points. Can we verify whether it must be relocated?
Watch out
Do not relocate, lock, stretch, or use the expansion joint to absorb a layout error without engineering or manufacturer direction.
Check
Compare the installed location with current drawings and details.
Identify nearby anchors, guides, supports, equipment, and penetrations.
Check whether the joint is compressed, stretched, twisted, or carrying weight.
Document actual dimensions and temperature conditions.
