Post-tensioning quantity takeoffs

Turn PT drawings into a traceable takeoff — in minutes, not days.

Upload your post-tensioning drawings as PDF. PT-TAKEOFF returns a detailed quantity takeoff you can defend line by line: an Excel workbook with live formulas and a PDF extract. Every quantity is computed by deterministic code — never guessed.

Illustrative. Values you see in your workbook are computed from your drawings, each traceable to a sheet and a formula.

How it works

Three steps. Full traceability at every one.

Upload your drawings

Drop in PT drawings exported from CAD as PDF — up to 30 sheets per takeoff. Nothing leaves your account without your action.

We read the tendon register

The tendon register is transcribed with AI assistance, then every quantity is derived by deterministic Python — lengths, strand, anchorages, duct, grout.

Download & verify

Get an Excel workbook with live formulas and a PDF extract. Filter by confidence, check the Verify sheet, and sign off with the audit trail intact.

Built for engineers

Every number is defensible.

Never invented

Quantities come only from deterministic code applied to what's on the drawing. The AI transcribes the register; it does not estimate quantities.

Confidence on every line

Each row is flagged HIGH MEDIUM LOW so you know exactly where to focus your review.

Live formulas

The Excel workbook ships with working formulas, not flat values — change an input and the totals recompute. Nothing is hidden.

Drawing references

Every line cites the sheet it came from, so a reviewer can trace any quantity straight back to the source drawing.

Verify sheet

A dedicated Verify tab surfaces cross-checks and anything that needs a human decision — before it reaches your BOQ.
