We have a project where the general contractor is stating that the vertical penetration in the stairwell landing, where the standpipes are located, need to be sealed.
They are not asking for it to be a fire-rated seal, but they say some sort of seal will be required. I know on past projects this typically was never a requirement. I have searched NFPA and the IBC with no luck on finding something that would insinuate that no seal is required for the vertical standpipes openings within the rated stair.
Is a seal required for these stair landing penetrations?
Any input is much appreciated.
