Firestopping estimating starts with the life safety plan.
Firestopping is priced by penetration and joint, but those quantities come from overlaying rated assemblies on the life safety plan with every MEP penetration. RenderDraw helps by proposing rated wall lengths and MEP runs crossing them, with the source attached for review.

- Rated assemblies from life safety plans
- Penetrations by trade
- Joints and head-of-wall

What to count.
| Item | Unit | Source |
|---|---|---|
| Rated wall length by rating | LF | Life safety plans |
| Head-of-wall joints | LF | Rated wall LF, partition details |
| Penetrations by trade and size | Each | MEP plans crossing rated walls and floors |
| Floor penetrations | Each | MEP risers, plans |
| Perimeter joints | LF | Curtain wall, slab edge details |
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 |

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.

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 firestopping estimated?
Count penetrations and measure joints in rated assemblies, by type and size, and price by tested system.
Can AI find penetrations?
RenderDraw proposes rated walls and MEP runs; crossings are flagged for estimator review.
What should we send?
Life safety plans, partition types, MEP plans and the firestopping spec.
Who usually does firestopping?
It varies by contract: a specialty sub or each MEP trade. Confirm in the spec.

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.
