BIM OOTB
Two databases. One browser. Zero install. No permission required.
⚠ Alpha software. Expect sharp edges, breaking changes, and missing features. Not for production use.
A building is a manufactured product with coordinates. Drop an IFC file into a browser tab and watch it become what it always should have been — a thing you can query, cost, schedule, and own. No installer. No seat license. No server to rent. No salesman to call.
Beside it runs a full ERP kernel, folded from the Compiere → ADempiere → iDempiere lineage, that reproduces a real ERP's books to the cent — serverless, offline, in the same tab. The building becomes a procurement order. The order becomes accounts. All of it from one signed log you can replay and verify yourself.
Why this exists, plainly. The big tools are cathedrals — and cathedrals are worth building. They house real work, they employ brilliant engineers, they carry decades of hard-won domain knowledge. This stands on all of that, gratefully. What it adds is a bazaar beside the cathedral — open, composable, running in a browser tab — because the best ideas in this industry deserve to reach the widest possible hands. The ambition is to become the first truly unified BIM-ERP platform: not by displacing what came before, but by taking the next step nobody has taken yet.
Who's doing this. I'm Redhuan D. Oon — red1. I helped found the ADempiere ERP project in 2006, arriving with a Java ERP and PostgreSQL background — now facing an entirely new but exciting learning curve. One person, a machine, various AI led by Claude Code as pair programmer that overworks and overdrank, and a genuine curiosity about how far the discipline can actually stretch — watching a building become a procurement order, watching geometry fold into accounts, watching it all fit inside a single browser tab.
How it's built — the only three rules.
- Extract or compile, never invent. Every number traces to a real source.
- Talk is cheap. Every claim here has a witness you can run; corrupt the rule and the number goes wrong. If it doesn't reproduce, it isn't true.
- In the open, or not at all. MIT-licensed, because a tool you can't fork is a tool that owns you.
It won't replace Autodesk or SAP this year. It already does things they were never shaped to do — and it gets closer every week, mostly because it's a genuine blast to build.
This README is the doorway, not the house. The works — the proofs, the changes, the arguments — are in the docs and the commit log below. Scour them, break the thing, send a fix.
Build it like you mean it. Give it away like it's nothing.

BIM side
A browser-native IFC viewer — no server, no cloud subscription, no install. Open a URL, drop an IFC file, view a full model with scheduling, cost and clash, all in one tab.
- 3D/2D Viewer — IFC2x3 + IFC4, parsed entirely in-browser via web-ifc
- Clash Detection — rule-based spatial clash with snag tracking
- 4D Time Machine — construction sequence playback from BOM data
- 5D Cost Estimation — 17 country rate templates, Excel export
- BOM Engine — Bill of Materials extraction and verb expansion, fully in JavaScript
- Rosetta Stone benchmarks — every geometry claim verified to 0.000 mm against the original IFC extraction; position, rotation and facing each have a named witness script that must pass before a commit lands
- System Monitor — live health dashboard under the System login: service-worker version, release row linked to the auto-cut GitHub release, op-log gauge, field vitals that animate on open
- PWA — works offline after first visit
- 18 Languages — auto-detected from browser locale
