Special inspectionSprayed fire-resistive materials (SFRM) special inspection checklist
Fireproofing is only as good as its thickness, density and bond, and finishes hide all three. The independent inspector confirms the substrate, witnesses the testing, and records the results before the assembly is enclosed.
The checklist
Every item, and the photo evidence it needs
The photo count on each row is what RTI would require before the item can be submitted. Work the list here and watch the gate hold, or load it into RTI and let it enforce the real thing.
Substrate and materials
Structural work below the fireproofing is complete and accepted
Bolting, welding and any structural signoffs are closed before coating begins.
Substrate clean and prepared to receive the material
Surfaces free of oil, loose scale and incompatible primers per the listing.
Material and listing match the required assembly rating
Product and application match the tested assembly for the required hourly rating.
Clips, hangers and attachments to the steel installed first
Ceiling hangers, duct and pipe supports and other attachments in place before spraying, so the material is not cut later.
Air and steel temperature within the manufacturer's range
Ambient and substrate temperature and ventilation within the manufacturer's application limits; reading recorded before spraying.
Application and verification
Applied thickness verified at the specified frequency
Thickness gauge readings taken across members and recorded with locations.
Required thickness per member taken from the approved schedule
Design thickness for each member size and rating comes from the approved submittal and listing, and sampling follows the statement of special inspections.
No photoDensity verified where required
Density samples or tests witnessed and recorded against the specified value.
Bond and cohesion checked where required
Adhesion/cohesion testing performed at the specified frequency.
Coverage continuous at flanges, webs, connections and deck flutes
No bare steel, voids, cracks or delamination; flutes filled or left open as the listed design requires.
Patching and closeout
Damaged and patched areas repaired and re-verified
Areas disturbed by other trades patched to the same thickness and re-recorded.
Thin, low-density or poorly bonded areas marked with the reading
Readings below the scheduled thickness, or failed density or bond results, marked on the member and shown to the applicator before ceilings or walls close in.
No photoAreas enclosed with open fireproofing items listed by floor
Any area enclosed before a deficiency was corrected listed by floor and gridline on the report to the design professional of record and the building official.
No photo
What usually sends this back
The failures are almost always the evidence, not the work
- Material applied over a connection or member that was never signed off structurally.
- Thickness and density accepted by eye rather than by witnessed testing at the required frequency.
- Damaged or patched areas left unrecorded after other trades worked around the steel.
Common questions
6 answers
- What does this sprayed fireproofing checklist cover?
- 13 items across 3 sections, covering substrate and materials, application and verification, patching and closeout. Each item spells out what the person walking the job is actually looking for, not just a box to tick.
- Who should run this inspection?
- A third-party or owner's-rep special inspector for fire-resistive materials, with the applicator.
- When in the schedule should this walk happen?
- After the structure is accepted and the substrate is ready, during application, and before the assembly is enclosed.
- Why do these items ask for a photo?
- 10 of the 13 items call for photo evidence, 15 photos in all. A checklist answer without the photo is a claim; the photo is what makes the record worth something in a dispute and lets a reviewer approve work without re-walking the job.
- What most often fails a sprayed fireproofing inspection?
- Material applied over a connection or member that was never signed off structurally. Thickness and density accepted by eye rather than by witnessed testing at the required frequency. Damaged or patched areas left unrecorded after other trades worked around the steel.
- Can I use this checklist in RTI?
- Yes. Start a free RTI workspace, build this list as a checklist, and the Photo Gate holds the submit button until every mandatory item is answered and its photos are attached. Approved inspections roll into a branded turnover package with a tamper evident audit trail.
