Automated Building Code Checking: Regulatory Compliance via IFC-SG Standard
Explore how modern municipalities transition from 2D plan approvals to automated 3D OpenBIM verification using standardized regulatory IFC schemas.
Traditional building permit checks require manual review of hundreds of 2D CAD drawings. Regulatory BIM initiatives like Singapore’s IFC-SG set a global precedent for automated machine-readable code compliance.
1. Structuring Models for Machine-Readable Code Audit
Automated checking engines require standardized parameter naming and space boundary definitions. Enforcing schema rules like IfcSpace and property set extensions guarantees spatial clearance validation.
2. Writing Rulesets via Open Source Rule Engines (Solibri / IfcOpenShell)
By combining Python scripts via ifcopenshell with buildingSMART IDS rules, municipal servers validate egress widths, accessibility slopes, and fire compartmentation automatically.
3. Eliminating Plan Approval Bottlenecks with BCF Integration
Instead of rejecting entire model submissions, automated checkers return pinpointed BCF (BIM Collaboration Format) markers directly into the architect’s CAD authoring software for immediate revision.
