OpenConstructionERP

Open-source construction cost estimation — BOQ, AI matching, CAD/BIM takeoff.

▶ After pip install, type one command: openconstructionerp

That's the only thing you need to remember. It prints a welcome, asks press o + Enter to open the app in your browser, then starts the server at http://127.0.0.1:8080 (and shows a login).

Install

pip install openconstructionerp

Python 3.12+ required. That's it — no Docker, no Postgres, no Redis.

First run

openconstructionerp

This single command:

1. Creates a local SQLite database in your home data folder
2. Seeds demo data (projects, BOQs, cost catalogues)
3. Starts the API + UI at http://127.0.0.1:8080
4. Prints demo login credentials

No config files. No environment variables. It just works.

Subsequent runs

openconstructionerp

Same command every time. Your data persists between runs.

Other commands

openconstructionerp init-db    # create the local database
openconstructionerp serve      # start the server
openconstructionerp doctor     # health check if anything looks wrong
openconstructionerp welcome    # re-print the welcome screen

CLI reference

openconstructionerp serve   [--host HOST] [--port PORT] [--data-dir DIR] [--open] [--quiet]
openconstructionerp init-db [--data-dir DIR]    # Create local SQLite DB + data dirs
openconstructionerp doctor  [--port PORT]       # Run installation health checks
openconstructionerp seed    [--demo]            # Load demo project data
openconstructionerp version                     # Show version

What you get

• BOQ editor — hierarchical bill of quantities with assemblies, formulas, multi-currency
• Cost database — import your own rates (Excel/CSV) or use the bundled example templates
• AI estimation — vector search matches line items to historical cost data
• CAD/BIM takeoff — quantities from DWG/DXF and IFC/Revit (via DDC, no IfcOpenShell)
• 4D / 5D — cost-loaded schedule, earned value (SPI/CPI), cash-flow, what-if scenarios
• Validation — DIN 276, GAEB, NRM, MasterFormat rule packs flag issues at import
• Reporting — PDF/Excel exports, dashboards, BCF issue exchange

Configuration (optional)

Everything works with zero config. To customize, pass flags or set environment variables:

openconstructionerp serve --port 9000 --data-dir /var/lib/oce

# Or via environment:
DATABASE_URL=postgresql+asyncpg://user:pass@host/db   # Use Postgres instead of SQLite
OE_CLI_PORT=9000                                       # Change the port
OE_CLI_DATA_DIR=/var/lib/oce                           # Change the data location
