How it works
Three steps, and the surveyor stays in control.
QuantiFlow does the measuring. You keep the judgement — confirming the parameters that drawings alone don't settle.
Upload the drawing set
Drop in your PDF drawings. QuantiFlow reads the geometry, annotations, and schedules — no manual scaling, no digitiser.
Confirm the parameters
The AI measures linear metres per floor; you confirm storey heights and specifics in an editable column. Measurement meets judgement.
Export the estimate
A priced Bill of Quantities with quantities measured in accordance with RICS NRM2. Export to PDF or Excel in a click, every quantity traceable to the drawing it came from.
Why QuantiFlow
Built around how QS work actually gets done.
Save hours on takeoffs
What used to take a full day takes minutes. Upload a PDF set and let the AI extract every dimension, material, and quantity — no manual measurement.
Eliminate double-counting
The cross-referencing engine tracks every item across revisions and flags discrepancies before they become pricing errors — or contractual disputes.
Current UK rates
Each line is priced against a maintained UK rate library, kept current — so your Bill reflects today's market, not last quarter's spreadsheet.
Features
Everything your practice needs, in one platform.
AI quantity takeoff
Extract quantities straight from your drawings.
Upload your PDF drawings and QuantiFlow reads the geometry, annotations, and schedules automatically. No manual scaling, no digitiser — just measured quantities, referenced back to the drawing.

Drawing cross-referencing
Catch double-counting before it costs you.
QuantiFlow checks every uploaded drawing against the others, identifying overlapping measurement zones and conflicting annotations. Every conflict flagged, every saving logged in the audit trail.
Conflict detectionFloor slab area measured twice: 24.6 m² overlap between structural and architectural plans.
Brickwork elevation measured on two drawings with conflicting window openings.
UK rate library
Every item priced against UK market rates.
Each line in your BoQ is priced against a maintained UK materials rate library, kept current. No more manual rate lookups, no more outdated price books — with the final rate always yours to adjust.

The quality gate
“Every measurement pattern is benchmarked against projects I've priced by hand. If it doesn't match a surveyor's own take-off, it doesn't ship.”
