AI takeoff

AI takeoff, properly.

Most “automated” takeoff is symbol matching with a thesaurus. Ours is a vision model trained on UK construction drawings. The difference matters.

How the model sees a drawing

Pattern matching reads shapes. We read drawings.

Symbol-matching tools work like a spellchecker. They have a library of shapes and look for things that match. New symbol? Retrain or add it manually. Drawing slightly off? Misses counts.

A trained vision model reads the drawing the way an estimator does. Context matters. A circle next to a wall isn’t always the same as a circle in the middle of a room. The model has seen hundreds of thousands of drawings and learned what conventions mean.

What this gets you

The boring practical bits.

New symbols without retraining

Encounter a symbol the model hasn't seen? It learns from one or two corrections, no library update needed.

Marked-up scans handled

Red-pen revisions, contractor markups, photocopies. The model reads them the way an estimator does.

Photographs of plans handled

Phone snap of a drawing on a desk. Perspective, shadow, the corner of your hand — all handled.

By trade

The same engine, the trade-specific page.

One model handles every discipline. Pick the trade closest to the work you do for what gets counted, what gets measured, and the conventions we read.

Built carefully

Patented, funded, UK-built.

Built with Innovate UK Smart Grants funding from October 2021. The takeoff method is protected by UK patent GB2631290. The team behind it sits inside the Ensign group of UK construction software firms.

Book a demo

Bring a drawing the last tool got wrong.

The most useful demo we run is on a drawing where another tool gave you a bad count. Send it through.
