1 · Package document set

Every submittal package includes these, in this order.

Cover sheet — project, submittal number, spec section(s), date, and the submitting company
Transmittal — item list keyed to the schedule, with the reviewer/GC and the type (partial or full)
Table of contents / section dividers so the reviewer can navigate
Product data — manufacturer cut sheets marked to the exact model, options, and finish being furnished (strike what doesn't apply)
Shop drawings for anything fabricated or custom, matched to the drawings and schedules
Samples or physical mock-ups where the specification requires visual approval
Certifications & test reports the spec calls up (listings, ratings, compliance letters)
O&M data and warranties where required at this stage
Substitution request forms for any product not on the approved-manufacturer list

2 · Insulation & Firestopping scope — by spec section

Pull a submittal for each section in your scope; confirm the spec's Part 1 list.

Insulation product data for each type: R-value, thickness, facing, and where it is used (walls, roof, below slab, continuous insulation)
Fire test data for insulation, such as flame spread and smoke ratings, and the thermal barrier needed over exposed foam
Vapor retarder and accessory data where the spec calls for them
A firestop schedule listing every penetration and joint type: wall or floor type, rating, and what passes through (pipe material and size, cable, duct)
The tested system drawing for each condition on the schedule, from a recognized listing
Engineering judgments from the maker for any condition with no tested system
Product data for each firestop sealant, wrap, collar and device used in those systems
Installer qualifications and the inspection plan where the spec requires them

3 · Before you submit — common rejection reasons to rule out

Reviewers flag these first. Verify each is not an issue before you send.

Firestop product data with no tested system drawings
Tested systems that do not match the real wall or floor type, item size or rating
Penetrations from some trades missing from the firestop schedule
Engineering judgments missing, or not from the maker
Products from different firestop makers mixed within one system
Insulation without R-value or fire test data
Exposed foam insulation without the required thermal barrier
