datadrivenconstruction/OpenConstructionERP

Open-source construction ERP - BOQ, PDF/CAD/BIM takeoff, AI cost matching, 293 guided cases. 55,000 priced positions, 44 languages, 195 modules. AGPL-3.0. pip install openconstructionerp

What it solves

OpenConstructionERP addresses the high cost, proprietary nature, and regional limitations of construction cost estimation and project management software. It provides a free, open-source, self-hosted alternative that supports a vast array of global regional standards and languages, preventing vendor lock-in and ensuring data privacy.

How it works

It functions as a modular platform (described as "WordPress for construction companies") where users can pick, replace, or build their own modules for specific needs. The system integrates several key technical capabilities:

  • Estimation & Takeoff: Supports BIM (RVT, IFC), CAD (DWG, DGN), and PDF quantification, linking these measurements directly to a Bill of Quantities (BOQ).
  • AI Integration: Connects to various LLM providers (such as OpenAI, Anthropic, and Gemini) to assist with smart estimation and cost finding.
  • Project Lifecycle Management: Includes 4D scheduling, 5D cost modeling, tendering, and property development tracking from lead to handover.
  • Global Support: Includes a database of over 120,000 cost items and supports 30+ regional standards and 44 languages.

Who it’s for

Construction companies, estimators, project managers, and developers who need a professional-grade ERP for BOQ management, BIM/CAD takeoff, and cost control without the high subscription fees of proprietary software.

Highlights

  • Modular Architecture: 191 backend modules allowing for highly customized software assembly.
  • Extensive Data: Built-in cost databases with 120K+ items and 7K+ priced resources.
  • ** uma Global Reach**: Support for 44 languages and 30+ regional standards (e.g., DIN 276, CSI MasterFormat).
  • Self-Hosted: Full control over data with no per-seat fees or subscriptions.
  • Multi-Format Takeoff: Native support for RVT, IFC, DWG, DGN, and PDF quantification.
