About

A complete AI-powered construction estimating system that takes you from RFP to submitted bid — covering scope analysis, material takeoffs, labor estimates, subcontractor bid packages, bid narratives, RFIs, and change orders. Not a calculator. A system that produces every document you need to bid and win.

The system starts with a Scope Analyzer that interviews you about the project and produces a CSI MasterFormat-organized scope breakdown. From there, downstream prompts generate material quantities with waste factors, labor hours with RS Means productivity rates, trade-specific sub bid packages, and a professional bid narrative that reads like it was written by a 20-year GC veteran.

Built from real construction estimating workflows used on $5M-$500M projects. Every prompt uses actual industry standards — CSI divisions, AIA markup structures, RS Means productivity factors — and produces output that's ready for submission, not a rough draft.

What makes this different

  • CSI MasterFormat organization — every output follows the industry-standard division structure
  • RS Means productivity factors — labor estimates based on real data, not guesswork
  • AIA-compliant change orders — proper markup structures that hold up in disputes
  • Trade-specific sub packages — not generic scopes, but detailed per-trade bid documents with interface points

What’s included

  • 7 production-ready AI prompts (scope analyzer, material takeoff, labor estimator, subcontractor scoper, bid narrative writer, RFI drafter, change order calculator)
  • 4 reference frameworks (CSI checklist, bid pricing template, sub evaluation matrix, change order log)
  • Platform setup guides (Claude Projects, Custom GPTs)
  • OpenClaw-compatible SKILL.md for autonomous agent execution
  • Step-by-step quickstart guide
