AI Takeoff & Estimating

Takeoffs and estimates in minutes, not days

Stop losing jobs to whoever quotes first — and stop losing margin to manual measuring errors.

Run a takeoff on your own plans

Upload a PDF and watch the AI mark up quantities, score its confidence, and seed a priced estimate.

Every builder knows the scene: a stack of plans, a scale ruler and an afternoon gone. Build Margin does the takeoff for you — drag in a PDF and the AI marks up quantities on the drawing, scores how confident it is on each one, and feeds them straight into a priced estimate seeded from your own assemblies. You review and confirm. No re-entry, no transcription errors, no quoting in two days when the builder up the road quoted in two hours.

The AI measures, you confirm

Quantities are marked up automatically on your PDF plans, each with a confidence score so you can check the low-confidence lines before they hit your estimate.

Estimates seeded, not built from scratch

Detected items flow into an estimate built from your own assembly recipes and rates — so the numbers reflect how you actually build, not a generic template.

Version every estimate

Track multiple versions of an estimate against one project. Revise with confidence and never lose the quote you sent last week.

Common questions

Does the AI replace my estimator?

No. It does the repetitive takeoff and seeds the estimate from your own assembly recipes — you confirm every line. It removes the grunt work, not the judgement.

What plan formats can I upload?

PDF plans. The takeoff marks up quantities directly on the drawing so you can see exactly what was measured and where.

Does it handle metric units and Australian Standards?

Yes. Build Margin is built for Australian metric units and AS standards from the ground up — it is not a US tool with the units swapped.

How accurate is the AI takeoff?

Every detected item carries a confidence score. You review the low-confidence lines before they reach your estimate, so accuracy stays in your hands.
