Build an IFC Accessibility Ramp and Door Auditor

Inspect door clear widths and ramp inclinations in architectural IFC models to assess compliance with accessibility guidelines. Generate remedial design tasks for substandard circulation routes.

Universal Design Accessibility Auditor

Query IfcDoor and IfcRamp elements with dimensions from architectural model files.

Compare clear door opening widths against the standard 850mm barrier-free threshold.

Calculate ramp slope gradients and identify segments exceeding maximum 1:12 inclination.

Produce prioritized non-conformance action items for architectural revision.

Accessibility scorecard dashboard displaying non-compliant circulation elements with direct 3D tags.

Sample IFC building models containing internal doors and circulation ramps from open IFC repositories. Starter examples below are synthetic. They are not downloaded records.

IfcOpenShell Leverages IfcOpenShell Python schema parsing APIs and ifcbimtester test definitions for property validation.

pydantic-ai, fastapi, rich. Pydantic AI guarantees structured validation of geometric element properties and accessibility rule outputs. Fast inference model specialized in numerical condition checking and technical compliance documentation.

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.

Processes IfcDoor and IfcRamp entity parameters extracted via IfcOpenShell conventions.

Flags doors with clear width below 0.85 meters.

Flags ramps with slope gradient steeper than 8.33 percent (1:12 slope).

Accessibility audit results assist architects; official building code approval must be granted by code compliance officials. Use mock external writes. Require human review before any real deployment.
