Every estimator knows the drill. You get a set of plans. You fire up the scale ruler — or the on-screen measuring tool — and you start counting. Doors. Windows. Linear metres of wall framing. Square metres of plasterboard. Hours of your life that you're never getting back.
It's tedious, error-prone, and slow. And in a competitive market where the first quote in the inbox wins, slow is expensive.
What AI takeoff actually does
Build Margin's AI Takeoff engine reads your uploaded plans the same way an experienced estimator would — except it does it in minutes, not hours.
Upload your PDF drawings. The AI identifies rooms, walls, openings, and annotations. It calculates areas, perimeters, counts, and lengths. It outputs a structured quantity list that flows directly into your estimate.
The 70% time saving is real
We've measured it across hundreds of projects on the platform. Estimators who use AI Takeoff spend an average of 70% less time on the measurement and quantification phase compared to manual methods.
That's not 70% less accuracy — the AI matches or exceeds manual takeoff accuracy when the plans are clean and properly scaled. You review and adjust, but you're refining, not starting from scratch.
How it fits your workflow
AI Takeoff isn't a standalone tool that lives in a separate app. It's built into the estimating flow:
- Upload plans to your project
- Run AI Takeoff — quantities populate automatically
- Review, adjust, add your rates
- Send RFQs to suppliers from the same screen
- Build your estimate and generate the quote
Everything stays in one place. No exporting CSVs, no re-keying numbers, no context switching.
When to trust it (and when to double-check)
AI Takeoff works best on clear, well-dimensioned architectural plans. For complex structural or services drawings, you'll want to review the output more carefully. The tool flags low-confidence measurements so you know exactly where to focus your attention.
Think of it as a very fast junior estimator who gets 90% right on the first pass. Your job shifts from doing the work to checking the work — and that's a fundamentally better use of your time.
