Takeoff in hours,
judgement kept human.

AI construction estimating means measuring quantities from drawings and models automatically, checking them against the specification for scope gaps, and levelling subcontractor quotes, so an estimator spends the bid period pricing risk rather than counting.

Off-the-shelf AI takeoff tools read PDF drawings and recognise symbols, rooms and runs well, and many teams already use one. Three things usually stay manual. The quantities are not tied back to the specification, so an item in the spec book with no line in the estimate goes unnoticed. Rates come from a spreadsheet only one estimator fully understands. And subcontractor quotes arrive in different formats with different exclusions, so comparing them is a day’s work per package.

We build around those gaps, using your cost database and past tenders. Where an IFC model exists, quantities come from it directly and the drawing takeoff becomes a cross-check.

We rerun tenders you have already priced, ideally including ones that went to contract, so the final account shows what the quantities really were. Takeoff is judged trade by trade against those quantities, and the scope-gap check on whether it finds the items that later became variations. The results tell you which trades to trust it on and which still need a full manual measure.

Drawings arrive from the design team through Procore, ACC, Aconex or email; quantities go to your estimating system or a structured export. For the design side of the same documents, see tender responses for design firms, and once on site, RFIs and submittals.
