Fireproofing takeoff from the steel takeoff.
Spray-applied and intumescent fireproofing are priced from the same members a steel estimator counts, plus ratings and UL designs. RenderDraw proposes members by size from framing plans, with the source attached, so fireproofing estimators can apply ratings and thickness rules.

What to capture.
| Item | Unit | Source |
|---|---|---|
| Beams and columns by size | LF | Framing plans, schedules |
| Rating and UL design | By area | Life safety plans, spec |
| Deck | SF | Framing plans |
| Thickness | By member and rating | UL design tables |
The quantities a insulation estimator actually needs
These are the items RenderDraw proposes from the drawings, each linked to the sheet it came from, for your estimator to accept, correct or reject.
| Item | What is measured or counted | Where it comes from |
|---|---|---|
| Wall insulation | Area by type and R-value | Wall sections, partition types |
| Roof insulation | Area by thickness and system | Roof plans, sections |
| Spray foam | Area × thickness to board feet | Sections, spec |
| Firestopping | Penetration counts by rating | Plans, UL details |
| Acoustic | Sound batts by partition type | Partition legend |
From plan set to reviewed quantities.
AI-powered, human-approved. Each stage records what ran, what changed and who approved it.
Start with your bid package
Drawings, specs and addenda together: wall sections, partition types, roof sections and the Division 07 insulation spec.
AI proposes quantities
Counts, lengths and areas come back with the source sheet and location attached to every row.
Estimator review
Low-confidence items surface first. Your estimator accepts, corrects or rejects each one.
Map to your assemblies
Approved quantities map to your items, assemblies and estimating assumptions.
Price reviewed rows
Labor units, material pricing and supplier quotes apply only to rows that passed review.
Hand off with evidence
Approved quantities move on to pricing and visual CPQ with the evidence trail still attached.

What we checked (November 2026)
- Code (IBC 2021, §704.13): SFRM must match the listing. Sprayed fire-resistant material has to be applied in line with the fire-resistance rating and its listing. That covers minimum thickness and dry density, method of application, substrate condition and any bonding adhesives or sealants (§704.13.1).
- Substrate condition (§704.13.3):
- Steel must be free of dirt, oil, loose scale and anything that prevents adhesion.
- Primed or painted steel is allowed only where testing shows adhesion is maintained.
- Check the paint spec. A shop primer on beams that get fireproofing can change both the product and the price.
- Thickness comes from the listed design. Thickness depends on the UL (or other listed) design, the rating and the member's size, usually expressed as its W/D ratio. Takeoff gives you members by size and length; the fireproofing estimator applies thickness from the design.
- Intumescent coatings are priced by dry film thickness and surface area per foot. They are more sensitive to member size than SFRM.
The AI drafts. Your estimator decides.
Speed is easy to promise. Defensible numbers are the job, so RenderDraw keeps the estimator in control of every quantity that gets priced.
- Source on every row. Each quantity keeps its source sheet, location and reviewer decision.
- Lowest confidence first. The review queue shows the drawing tile with the detection highlighted and the extracted value.
- Uncertain items flagged, not hidden. Anything the AI can't confirm goes to the estimator rather than being guessed.
- Nothing priced before approval. Rows move on to pricing only after they are accepted.
Questions estimators ask
How is fireproofing estimated?
From member sizes and lengths, ratings and UL designs, converted to surface area and thickness, then material and labor.
Does RenderDraw calculate thickness?
No. It provides members by size; thickness comes from the UL design and spec.
What should we send?
Structural framing plans, schedules, life safety plans and the fireproofing spec.
Does it handle intumescent?
Member quantities apply to any system; system rules apply in pricing.
See what the AI reads on your own drawings.
Send one representative insulation plan set. RenderDraw reviews it and follows up with what the AI extracted and what it flagged for review. Your files remain private while the request is assessed, and there is no obligation.
- Upload wall sections, partition types, roof sections and the Division 07 insulation spec.
- RenderDraw reviews the set and the scope you want tested.
- We follow up with extracted quantities, flagged items and next steps.
