Firestopping

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.

What gets taken off

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.

How it works

From plan set to reviewed quantities.

AI-powered, human-approved. Each stage records what ran, what changed and who approved it.

Send one plan set

Upload wall sections, partition types, roof sections and the Division 07 insulation spec. Add an addendum if you have one.

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.

Supported files and tasks depend on your trade and implementation. Confirm them in the free sample run.

Human review, by design

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.

FAQ

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.

Start small

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.

  1. Upload wall sections, partition types, roof sections and the Division 07 insulation spec.
  2. RenderDraw reviews the set and the scope you want tested.
  3. We follow up with extracted quantities, flagged items and next steps.
