AI Takeoff & Estimating · Industrial

Reads the drawings. Extracts the quantities. Applies the spec.

theTakeoff reads a full industrial bid package — P&IDs, isometrics, general arrangements, schedules — and returns a priced, evidence-linked takeoff your estimators verify line by line. Click any number and land on the exact spot on the drawing it came from.

The Problem

Estimator hours are the ceiling on how much work you can win.

The piping scope alone on an industrial bid runs ~875 estimator-hours. Steel, electrical, instrumentation and insulation stack on top of it. So bids get passed on — not because the work is unwinnable, but because there aren't enough hours in the bid window to price it.

It was never a cost problem. It's a capacity problem.

Intake

Whatever the bid package gives you.

No clean data required. theTakeoff reads what actually arrives — PDFs on a shared drive, scanned sheets, native CAD, 3D model exports where they exist.

P&IDs

Line numbers, equipment and instrument tags, valve counts and classes, spec breaks, insulation and tracing codes

Piping isometrics

Lengths, fittings, flanges, valves, welds and spool breaks — plus the gaskets and stud bolts that are never drawn

General arrangements

Equipment positions, scaled routing where isometrics don't exist yet, structural context

Line lists & schedules

The tabular register that joins the whole set together

Structural drawings

Member marks and sizes, connection callouts, and the schedules issued with them

Review and verify

The product does the counting. You hold the judgment.

theTakeoff.ai is not a black box. It's a review tool that produces a draft takeoff and asks you to check it. Items below confidence threshold are flagged.

Coverage

Built for the people who own the welders.

theTakeoff is for firms that self-perform industrial work and price it themselves. Four kinds of company, one unit of work: weld diameter-inch.

Contractors — Industrial primes running several crafts in-house, usually with a fab shop and a turnaround division attached.

Subcontractors — Specialty trade contractors who self-perform a single discipline in the field.

Verification

The engine does the counting.
You stay the authority.

theTakeoff extracts about 70% of a package on the first pass. We publish that number instead of a rounder one, because the other 30% is the entire point of the product. An estimator who can't see what the machine got wrong can't sign the bid — and no number leaves this platform without an estimator putting their name to it.

A confidence score on every extracted item — the review queue sorts by uncertainty, so your time goes where the machine is least sure.

Evidence links on every number. Click a quantity, land on the exact spot on the drawing it came from.

Keyboard-first review. Bulk-accept the high-confidence items, work the rest.

A verification meter that reports measured accuracy on your project — not ours.

Excel export, evidence-linked, in your template.

The platform

One platform. Every trade in the industrial bid.

Piping is live. Structural is building. Tell us which discipline to ship next — we build in the order estimators ask for.
