openconstructionerp 6.4.0

Open-source construction cost estimation, multi-currency BOQ, AI vector matching, CAD/BIM takeoff without IfcOpenShell, resource-based cost DB import with example templates, 48 regional catalogues, 24 languages. AGPL-3.0. After install, run: openconstructionerp

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. Starts an embedded PostgreSQL database in your home data folder (no Docker, nothing to install)
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.

If openconstructionerp is not found right after install, pip most likely put the launcher in a Scripts folder that is not on your PATH (this is common on Windows). Run it through Python instead. This works from any folder and is the exact same app:

python -m openconstructionerp

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
