"There are no wheels yet, but the thing is running"

TL;DR

This project explores IFC5 and Native IFC collaborative worklows based on Git.

The Challenge

• AEC/O Hackathon 2025 Munich Edition
• Problem statement

Problem Statement

• Architects and planners rely on a broad ecosystem of software tools,
• yet poor data integration between these tools creates major bottlenecks in the design process.
• This fragmentation prevents holistic project optimization and slows down coordination.

Data Stream

• Although OpenBIM ✅ aims to support interoperability, it still lacks robust mechanisms for

bi-directional data exchange ✅

• —particularly when it comes to re-integrating data into CAD and CDE environments.
• Existing initiatives often do not prioritize full OpenBIM compliance, leaving a clear opportunity for alternative, standards-aligned solutions.

'Flat Modules' vs 'Monolithic Blob'

At the same time, the emerging modularized and layerized IFC5 standard ✅

• introduces new capabilities for more flexible, fine-grained, and machine-friendly data handling.
• These advances open the door to new workflows built around decentralized, event-driven data exchange rather than monolithic file transfers.
