ibuilder/massing

Open, self-hosted, IFC-native AEC platform: web BIM viewer + modeling, a ~100-module GC portal (RFIs, pay apps, CPM, construction accounting — double-entry GL/WIP → QuickBooks, e-sign), AI assist, IDS authoring, estimating + embodied carbon, a development proforma, and operate/dispose (CMMS, facility condition, rent roll, waterfall).

These files are ibuilder/massing's own configuration. They tell Claude Code, Codex and OpenCode how to work on this repository, so they are not mods to install elsewhere. Copy one as a starting point and replace the parts that are about this project.
