Automated IFC Staircase Geometry and Accessibility Code Compliance
Validating architectural stair risers, tread dimensions, handrail heights, and TS 9111 / ADA handicap ramp slopes programmatically from IFC building models.
Manual regulatory checks for vertical circulation elements like stairs and ramps are time-consuming and prone to oversight. Parsing semantic properties from IfcStair, IfcStairFlight, and IfcRamp entities enables automated rule verification against national building codes.
1. Analyzing Riser and Tread Proportions
Extracting vertical riser heights and horizontal goings from IfcStairFlight property sets allows algorithms to verify ergonomic formulas (e.g., 2 x Riser + Tread = Constant) instantly without manual scaling.
2. Handicap Ramp Slope and Landing Verification
Evaluating IfcRamp gradient vectors and intermediate landing lengths against accessibility regulations (such as TS 9111 and ADA standards) ensures barrier-free compliance across complex public facility layouts.
3. Generating Automated BCF Compliance Reports
Exporting failing spatial elements directly into BIM Collaboration Format (BCF) issues streamlines communication between architects, structural engineers, and code consultants.
