The project

An estimator spends hours finding the same facts in a drawing set before pricing anything. We built tools that index the drawings once, answer takeoff questions from that index, and produce the priced bid documents.

What we built

  • A drawing analyzer that indexes a PDF set into a sheet register, an object database and a specification wiki
  • A roof takeoff estimator
  • A bid-form generator for branded priced-takeoff PDFs and spreadsheet proposals
  • The workflow behind The Takeoff Desk, our estimating service

Built with

  • Claude skills
  • Python
  • ReportLab
  • openpyxl

Collaborative Concept is not a licensed contractor. Its takeoffs carry no contractor license and no engineering seal, and are delivered under its own name, separately from any licensed partner’s work.
