Build an IFC Staircase Egress Compliance Auditor

Inspect emergency staircases in architectural IFC models to assess life safety compliance. Validate tread depths and riser heights against standard building codes to flag evacuation hazards.

Life Safety Code Inspector

Upload an architectural IFC model into the compliance analysis engine.

Extract IfcStair and IfcStairFlight entities with associated dimensional boundaries.

Calculate average tread run and riser height dimensions.

Output a life safety audit summary highlighting non-compliant staircase geometries.

Audit dashboard showing 3D stair elements color-coded by geometric compliance, detailed riser/tread metrics, and an exportable PDF report.

Download public hospital and school IFC sample designs from open-source BuildingSMART test libraries. Starter examples below are synthetic. They are not downloaded records.

IfcOpenShell Parses IfcStair and IfcStairFlight geometry and dimensional attributes using IfcOpenShell Python.

pydantic-ai, ifcopenshell, fastapi. Pydantic AI ensures validated output structures conforming strictly to safety reporting standards. API-based instruction model capable of interpreting architectural safety criteria and summarizing violations.

Submit runnable source, pinned dependencies, setup commands, a working interface, example outputs, and a recorded end-to-end demo. Include tests and an action log.

Identifies all stair flight instances and extracts vertical riser and horizontal tread dimensions.

Flags any stair flight with a riser height exceeding 180mm or tread depth below 280mm.

Validates stair widths against the minimum 1000mm standard clearance.

Audit outcomes provide guidance for design revisions. On-site field measurements remain mandatory before municipal occupancy certification. Use mock external writes. Require human review before any real deployment.
