CPM (Construction Project Master) — A free MCP server connecting Claude & ChatGPT to full project planning automation
Every civil engineering project starts the same way. You call a consultant for a rough cost estimate. You dig through ministry guidelines to confirm permitting requirements. You build the BOQ spreadsheet by hand. Again. Engineers at small municipalities or contractors do it alone.
CPM changes that to a single conversation. Tell Claude or ChatGPT what you want to build — it handles cost estimation, legal procedures, BOQ Excel, investment report DOCX, and drawings automatically.
"The goal of this project is to reduce the inequality of access to expert knowledge.
Anyone should be able to run a proper preliminary project review — no consulting budget required."

comparison
Why Existing Approaches Fall Short
| Approach | Time | Cost | Limitation |
|---|
| Consulting firm | 1–4 weeks | Millions of KRW | Only for well-funded organizations |
| Manual preparation | Days to weeks | Staff hours | Requires deep expertise, error-prone |
| Estimating software | Hours | Paid subscription | Detailed design phase only |
| CPM (MCP) | Minutes | Free | Natural language, AI handles everything |
