PT-TAKEOFF: Post-Tensioning Drawings to Takeoff
PT-TAKEOFF describes a tool that turns post-tensioning PDF drawings into an Excel takeoff workbook and a PDF extract, with formulas, drawing references, and confidence flags.
- For
- Post-tensioning engineers reviewing quantity takeoffs
- Worth noticing
- The page distinguishes AI-assisted register transcription from deterministic Python quantity calculations and flags each line HIGH, MEDIUM, or LOW.
Field notes
The described workflow starts with PDF drawings (up to 30 sheets) and transcribes the tendon register with AI assistance; quantities are then calculated by deterministic Python. The proposed workbook includes live formulas, a Verify sheet, drawing references, and HIGH/MEDIUM/LOW confidence flags, alongside a PDF extract. The on-page workbook values are explicitly labeled illustrative, so they do not demonstrate a completed takeoff or independently verify calculation accuracy.
