Building Automated Regulatory Code Checking Engines for OpenBIM Models
Converting municipal planning laws and zoning regulations into computable JavaScript/WASM rule sets evaluated against IFC spatial structures.
Manual permit reviews for architectural drawings take weeks and introduce human error. Building an automated rule engine parses standardized IFC building models, validating door clear widths, ceiling heights, and fire safety distances in seconds.
1. Declarative Rule Definitions with buildingSMART IDS
Expressing regulatory requirements using Information Delivery Specification (IDS) XML/JSON schemas ensures property sets, classification tags, and geometric dimensional constraints are formally verified.
2. Topological Space & Pathfinding Validation
Constructing navigation mesh graphs from `IfcSpace` entities allows algorithms to measure actual egress walking distances to fire exits, verifying compliance with municipal emergency evacuation rules.
3. Visual Non-Compliance Reports & BCF Export
Highlighting failing building elements directly in the WebGL 3D viewport and exporting detailed BCF (Building Collaboration Format) issues enables design teams to resolve code violations rapidly.
