Verify the support elevation against the approved riser-support detail, floor elevation, connector location, insulation, and movement requirements before loading it.
The riser support is set below the elevation shown on the approved detail and lands at the duct reinforcement. I measured it from the floor benchmark. Do you want the support corrected before the section is loaded?
Watch out
Do not notch duct reinforcement, stack loose shims, or change the support elevation without direction.
Check
Measure the installed support from a verified benchmark.
Check the intended duct joint and reinforcement locations.
Confirm access for hardware, insulation, and inspection.
Document the difference from the approved detail.
