Studio 04 — BOQ
Drawings in. A priced BOQ you can defend.
Upload structural drawings. AI extracts every column, beam, slab and footing — then stops. You confirm each value against the sheet before a single quantity is computed. Unconfirmed data is never priced. Zero numbers in your bill are AI-generated.
How it works
The AI drafts. You confirm. Code computes.
Upload the drawings
Drop in structural PDFs. Each sheet is rendered at 300+ DPI — the resolution the small text on real drawings actually needs — and, where a sheet is large, tiled into overlapping quadrants so nothing gets lost to downscaling.
Vision extracts every element
A vision model reads each sheet and returns every column, beam, slab and footing — id, type, dimensions, grade, main bars and links — with a confidence on each. Anything inferred rather than explicitly dimensioned is marked low-confidence, with a source note.
Unclear reads become questions
Every low or medium-confidence field turns into one specific, one-line question — "Sheet 3, C4: how many 16 mm main bars?" — consolidated by sheet and element. The AI never guesses and quietly proceeds; it asks, or excludes the element as pending.
Confirm against the sheet
The review screen puts the extracted table beside the source drawing, low-confidence rows highlighted amber. You confirm, correct or exclude each element. Answers that look physically implausible trigger a follow-up rather than being accepted silently.
Deterministic takeoff, priced and exported
Confirmed elements only flow into the engine: concrete by shape, rebar at 0.00785·d² with lap length per your code, formwork per face. Add masonry and roof by hand, apply rates, and export a grouped, subtotalled BOQ to Excel — pending items listed but never priced.
Why the number holds
Three non-negotiables.
Wrong quantities become wrong material orders on real sites. One mistake ends trust — so the workflow is built to make that mistake structurally impossible.
No unconfirmed math
Extracted values are always "pending" until a human confirms them. The calculation engine never runs on unconfirmed data.
A question, not a guess
Every low or medium-confidence field produces a specific, answerable question, grouped by sheet and element id.
Numbers from formulas
All quantity math is deterministic code — never an AI-generated number. Every applied default is stated in the output.
