Riser Joint Cannot Be Completed With Shaft Wall Framing Installed

Fast answer

Coordinate the duct-install sequence with shaft-wall framing and close-in before the framing blocks joint access, support installation, damper access, or inspection.

What to check

1. Identify what framing is temporary and what is part of the rated assembly.
2. Check the remaining access to all joint sides and supports.
3. Verify required inspections before close-in.
4. Coordinate the approved sequence with the framing trade and superintendent.

Do not

Do not remove rated framing, cut studs, or close an incomplete joint behind the wall.

Ask the foreman

“The shaft-wall framing now blocks the backside of the next riser joint. I checked access from both floors and cannot complete the hardware. Can we coordinate the approved framing and duct sequence before continuing?”

Why it matters

Poor sequencing can bury incomplete work inside a rated shaft and force destructive rework.
