TK-01Takeoff & Redline
Measure the plans. Mark the record. Price the job.
Do your takeoff in minutes with AI-assisted measurement, then raise queries, cloud revisions and stamp approvals right on the drawing — with an audit trail that shows who did what, and quantities that land straight in your estimate.
Built for Australian & NZ residential builders · Metric, GST and SOPA throughout
AI-01AI Takeoff
The first pass measures itself
Upload the drawing set, confirm the scale once, and AI Takeoff finds slabs, walls, roof planes and openings — measured, layered and ready for review. You check the work; you don't do it twice.
Scale locked in once
Calibrate against a known dimension and every tool on the page measures true — 1:100, 1:200, or anything the architect dreamt up.
Layered like a real drawing set
Structure, services, finishes, external — measurements land on colour-coded layers you can show, hide and hand to the right trade.
Viewports for detail callouts
Detail at a different scale on the same sheet? Draw a viewport around it with its own scale. No more mental arithmetic.
TK-02Measurement tools
Five tools. Every quantity on the plan.
Precision you set per page — from 0.1 m for civil works down to millimetres for steel and joinery.

RL-01Redline markups
Redline: the red pen, made official
Everything you'd scrawl on a paper set — clouds, notes, stamps, sketches — now on the digital drawing, attributed and trackable. Raise an RFI mid-takeoff without breaking stride.
Revision clouds & callouts
Cloud the ambiguous setback, attach the question, and it's on the record as RFI-04 — not lost in a phone call.
Stamps
Approved, For review, Rev A, Draft. Approval stamps are permission-gated, so a stamp on a sheet actually means something.
Freehand pen
Sketch the fix the way you would on site — a smoothed vector line that stays sharp at any zoom.
Snapshot a region
Crop the detail, copy it, drop it in the RFQ email. Composited with your markups, at print-quality resolution.
Sheet hyperlinks
"See A-201" becomes a click, not a rummage. Link any region of a drawing to the sheet it references.
Undo everything
Fifty steps of undo and redo on the canvas, with keyboard shortcuts. Mark up with confidence.
RL-02Audit trail
Who measured it. Who queried it. Who signed it off.
Every measurement and markup carries its author, date and status — permanently. Group the list by layer, trade or author; filter to open queries; and when a variation dispute lands six months later, the record is already there.
RV-01Revision compare
Rev B landed. See exactly what moved.
Overlay two revisions of the same sheet and the differences light up — additions in blue, deletions in red. No more eyeballing two printouts on the ute bonnet. Update the takeoff for what actually changed, and only what changed.
TK-03One platform
The takeoff isn't the job. The margin is.
Standalone takeoff tools stop at a quantity list. In Build Margin, measured quantities flow into your estimate, your estimate seeds the project budget, and live margin tracking follows the job to handover.
