Document and drawing intelligence

Estimating from drawing sets

A multi-sheet drawing set becomes a priced bill of quantities in the format the tender already asks for, with unreadable lines flagged rather than guessed.

Proof of concept
Goes in
A multi-sheet drawing set, exactly as the client sent it
What we built
Layout-aware extraction for the structured sheets, vision for the drawn ones
Comes out
A hierarchical bill of quantities in the manufacturer’s own tender spreadsheet
The line it does not cross
A line it cannot read is marked and left blank, never guessed

Note 1 · The constraint

A commercial estimator at a luxury interior fit-out manufacturer spends days reading client drawings before pricing can begin. Rushed bids lose margin. Slow bids lose the job. The company cannot install new hardware in the factory and cannot expose its ERP, so anything we build has to work from the files themselves.

Note 2 · What we built

Drawings go in as the client sent them. Layout-aware extraction handles the structured sheets, vision handles the drawn ones, and the output is a hierarchical bill of quantities in the manufacturer's own tender spreadsheet with a configurable markup cascade. Any line the system is unsure of is marked and left blank for an estimator to clear. It is never filled with a plausible guess.

Note 3 · What transfers

Any business that quotes from documents it did not author has this problem — tenders, specifications, schedules of work, supplier price lists. The reading is the bottleneck, not the arithmetic.

Start with a prototype

Two to four weeks working from your own files, and at the end you hold something real. It is the cheapest way to find out whether any of this applies to you.
