Automated Fire Safety and Life Safety Evacuation Analysis in OpenBIM IFC

Evaluating egress walking distances, exit capacity bottlenecks, and fire resistance rating property sets directly inside browser-based BIM tools.

Ensuring life safety compliance requires auditing egress travel limits, fire-rated doors, and compartmentation barriers. Extracting spatial topology from IFC building models automates life-safety compliance checks before construction begins.

1. Dynamic Navigation Mesh Generation from IFC Spaces

Extracting floor plate geometries from `IfcSpace` boundaries constructs 2D navigation meshes, enabling Dijkstra or A* pathfinding algorithms to measure actual unimpeded egress travel distances to designated emergency exits.

2. Fire Compartmentation & Rating Property Audits

Inspecting `FireRating` property sets across wall (`IfcWall`) and door (`IfcDoor`) assemblies ensures continuous fire containment barriers exist around stairwell shafts and horizontal exit corridors.

3. Crowd Flow Bottleneck Simulation & BCF Reporting

Simulating egress agent flow rates through exit door clear widths calculates Required Safe Egress Time (RSET), automatically flagging capacity bottlenecks and issuing BCF compliance issues.
