BIM Checker is an automated statutory engineering and digital twin quality assurance platform built on the Bentley iTwin Platform. It bridges the gap between high-level architectural models and strict statutory design codes—empowering engineering teams to audit spatial clearances, egress widths, headroom drops, room areas, and fire compartmentation directly against live iModel changesets.
Core Capabilities
Dashboard: Executive compliance scorecards, evaluated element totals, and statutory health indicators.
Model Quality: ISO 19650 naming conformance, duplicate geometry detection, category auditing, and historical trend tracking.
iModel Browser: Explore federated discipline models (Architectural, Structural, Mechanical, Plumbing, Electrical), changeset timelines, and repository synchronization states.
BIM Requirements: Dynamic Rule Engine executing spatial clearance, headroom under MEP duct drops, effective door clear widths ("The 900mm Illusion"), corridor bottlenecks, and firecode integrity.
3D Viewer & Workbench: High-performance 3D WebGL viewport with thematic color overlays, level isolation, and camera zoom-to-defect.
Property Analysis: Safe, interactive ECSQL query console for deep diagnostic inspection and data extraction.
Publishing & Dynamic Aspects: Permanent injection of audit verdicts into live iModel dynamic aspects (IFCDynamic.Pset_BIMChecker_ExecutionAudit, Pset_BIMChecker_Fail).
Featured Walkthrough
Walkthrough: Configuring & Validating a Hospital iModel: A complete, end-to-end tutorial using the NHS Darlington Memorial Hospital (WRSH_*.ifc / IFC_Hospital) as the reference exemplar—covering GFA targets, door clear widths, corridor bottlenecks, soffit headroom under HVAC drops, and fire barrier continuity.
