Double-entry between take-off and estimate
You measure in one tool, then key every quantity into Excel by hand — twice the work, twice the chance of a slip.
One measurement, priced automaticallyBuilt for South African quantity surveyors
Take-off & estimatingthat prices itself.
Corbel is cloud take-off & estimating software for South African quantity surveyors. Draw your take-off once and the quantities and rates carry through to a priced ASAQS bill of quantities — automatically, in rands.

The problem
The measurement's done. Now do it all again in Excel.
Take-off lives in one tool, the estimate in another. Every measurement gets keyed twice — and every revision means rebuilding the bill by hand.
Quantities and rates drift apart
Dimensions live in one file, pricing in another. Change one and the other quietly goes stale — until a number in the bill is wrong.
Dimensions + recipe stay togetherRebuilding the BoQ every revision
A drawing revision lands and you rebuild the bill from scratch — re-measuring, re-keying and re-checking every affected line.
Re-measure and the bill updates itselfGeneric tools, local standards bolted on
Imported software assumes foreign units and formats — ASAQS, JBCC and VAT get bolted on afterwards, never built in.
ASAQS bills, JBCC, ZAR & VAT — built inHow it works
From drawing to priced BoQ in four moves.
The whole loop, start to finish — upload, measure, price, export. Not another estimating suite you'll spend a month configuring first.
1
Upload the drawing
Drop in a PDF. Corbel preps every page for measurement.
2
Confirm what it read
Corbel reads the schedule, room areas and scale. You confirm each reading and draw only what the drawing does not state.
3
Quantities price themselves
Measurements roll up live and price into the bill — no double-entry.
4
Export the BoQ
Send an ASAQS bill of quantities to Excel, PDF or CSV.
Measured in the browser. Priced in rands. Exported to Excel.
See it in action
One tool, from drawing to priced bill.
Measure straight off the drawing, watch the quantities price themselves into a bill, and send an ASAQS BoQ to Excel — all in one place, in the cloud.
Measure on the drawing
Calibrated lengths, areas and counts, drawn right on the PDF — the take-off viewer is the workspace, not a separate step.
Lengths · areas · counts — calibrated on the PDF
Prices itself into a BoQ
Every condition carries its rate, so quantities roll up into a priced ASAQS bill as you draw. No re-keying, no drift.

What you get
Everything from measure to bill, in one place.
Measure, price and export from one tool — built around the Condition, so every quantity carries its own rate and rolls up across the drawing.

The Condition
Dimensions + pricing recipe in one object, reused across pages.
Live quantities
Measurements roll up and reprice as you draw. No double-entry.
