Construction Intelligence Platform
Upload your construction drawings. Quantro reads every schedule, footing, column, beam, slab and wall — and turns them into a bid-ready BOQ, rebar cutting list and estimate.
01The blueprint
Drop in PDF plans and Quantro reads them like an estimator would — the plan first, then every footing, column, beam, slab and wall schedule — and builds the structure, element by element.
02Foundations
Isolated footings are counted, sized and detailed — excavation depth, concrete volume and the full bottom-mat reinforcement, both ways.

03Columns
Vertical bars, ties and hook lengths come straight off the column schedule — floor by floor, lift by lift — so your cutting list matches what gets built.

04Beams
Top and bottom bars with anchorage into the supports, stirrups across every clear span. Quantro takes off what an estimator would — and never loses count.

05Slabs
Quantro cuts a section through the frame to take off the suspended slabs — thickness, area, concrete and the 12 mm bottom mesh in both directions, bar by bar.

06Walls
Perimeter CHB walls go up block by block — net of every door and window opening — with core reinforcement and plastering on both faces.

Rebar cutting list
The same model becomes a cutting list your fabricator can work from — every bar mark with its shape, cut length and count. Then Quantro plans which stock lengths to buy so the offcuts stay small.
01Stock
3,491 pieces become a purchase of 909 stock bars across the lengths your supplier carries — grouped by diameter, one rack row per cutting pattern.
02Cut
Pieces of the same diameter share stock bars across marks. The saw follows the plan; what's left drops in the tray — 185.2 m of offcut, 1.9% of the steel bought.
03Bend
Footing U-bars, column kicks and hooks, closed ties and stirrups — bent from the cut lengths on the bar bending schedule, the same shapes you saw in the model.
04Bundle
Every piece lands in a tagged bundle — F1-BX, C1-T, B1-S… — ready to carry to the footing, column, beam, slab or wall it was cut for.
05Ready for the yard
The full list
The detailed cutting list behind the yard: bar marks, shapes, cut lengths and counts, the bars to buy, and how each stock bar is cut. Toggle the stock lengths here or on the 3D yard; both stay in sync.

The problem
Drawings and takeoffs, schedules, procurement and supplier coordination — each lives in its own tool, spreadsheet or group chat. Every hand-off is a chance for an error.
Drawings, takeoffs and quantities kept in separate files — no single source of truth.
Estimating, scheduling and reporting done by hand, leading to delays, errors and rework.
Contractors, subcontractors, suppliers and project teams working in silos.
Sourcing, quotations and purchase orders spread across channels and tools.
One platform
The quantities you just watched become the plan, the purchase orders and the supplier quotes — without re-keying a single line.
From PDF drawings to a bid-ready estimate.
From estimate to an executable project plan.
From material requirements to controlled purchasing.
The right materials, at the right price, from trusted suppliers.

Who it's for
From a single house to multi-site developments, Quantro scales with the work on your desk.
Houses, townhouses and subdivisions.
Offices, retail and mixed-use.
General and specialty contractors across all trades.
From single projects to multi-site developments.
Why Quantro
Automate takeoffs, quantities and the repetitive work between them.
Quantities traced back to the element and the drawing they came from.
Every trade and stakeholder working from the same numbers.
From small projects to enterprise and multi-site operations.
Quantro is a construction intelligence platform. You upload construction drawings and Quantro turns them into structured, bid-ready quantities: a bill of quantities, rebar cutting list, labor estimates and material costs. Project management, procurement and a supplier marketplace connect to the same data.
PDF construction drawings across disciplines: architectural, structural, MEP and plumbing.
Yes. Quantities and unit costs stay editable, and estimates export to Excel, CSV and XLSX as bid-ready reports.
Quantro is rolling out in stages, starting with Estimation. Project Management follows next, with Procurement and the Marketplace on the roadmap. Request a demo to join early access.
Builders and general contractors, specialty contractors, developers, engineers, architects, quantity surveyors and estimators working on residential, small commercial and multi-site projects.
