SUBMITTAL ACTION - NOT REVIEWED FOR CAUSE - A PLAUSIBLE RESPONSE? |
We are reworking our submittal procedures spec section and associated review stamp, and seeking a way to keep low priority submittals from piling up in our court beyond the allotted review period. Has anyone ever included a review stamp action: "Not Reviewed - Submitted out of Sequence", and/or "Not Reviewed - Review Contingent on Receipt of Related Items", or similar? If not, how have you handled reviews of such submittals that don't follow an approved schedule, or are a low priority with respect to critical path, or must be reviewed in relation to other submittals not yet received?

NFPA 285 AND PLASTIC INSULATION |
I have a wall assembly of 5/8" gyp board, 6" CFMF studs w/ 6" batt insulation, 1/2" exterior gyp board sheathing, 3" closed cell spray foam insulation, 1" airgap, and uninsulated metal siding. I was told I needed to apply intumescent coating to the spray foam insulation in order to pass NFPA 285. One of the reps I spoke to was surprised to hear assemblies with EPS and XPS insulation do not require the intumescent coating. Spray foam, EPS, and XPS are all plastic insulation. Why don't EPS and XPS require intumescent coating to pass NFPA 285?
