C&C Engineering & BIM Validation Tools
Practical, high-performance web applications and BIM IDS validation utilities for digital engineering, OpenBIM (IFC 4 / 4.3), and Bentley iTwin asset management.
1. BIM Checker (bim-check.itwin.app)
Automate statutory building code compliance, 3D spatial clearance sweeps, and IDS validation workflows on federated digital twins.
- Relational GFA & Brief Reconciliation: Reconcile multi-storey Gross Floor Area (GFA) and NHS HBN 00-01 clinical room areas against project briefs, automatically detecting uncomputed
NULL spaces and unit mismatches ($\text{ft}^2$ vs $\text{m}^2$).
- Effective Door & Corridor Clearances: Evaluate real unobstructed door opening widths ("The 900mm Illusion"), 3D door swing arcs, true-geometry corridor distance-field bottlenecks, and MEP soffit headroom drops.
- Zero-Connectivity & Dynamic BIS Aspect Publishing: Run audits in cloud or zero-connectivity BIM checking environments and publish verified compliance aspects (
Pset_BIMChecker_ExecutionAudit) directly into live iModels.

2. iTwin Digital Index (index.itwin.app)
Assess the quality, maturity, carbon footprint, and statutory completeness of engineering information in Bentley iModels and OpenBIM IFC datasets.
- Automated Property & IDS Validation: Detect missing, incomplete, or non-standard property sets across architectural, structural, and MEP discipline models (Validation Engine).
- Fire Safety Index (BS 8644-1): Audit Building Safety Act Gateway 2 fire compartmentation and door/wall fire ratings in 3D (Fire Index | Docs).
- Carbon Index (RICS WLCA & EC3): Calculate A1–A5 and whole-life embodied carbon directly from 3D solid geometry (Carbon Index | Docs).
- Asset & Class Index: Audit Location (LBS), Classification (CBS / Uniclass), and System (SBS) hierarchies (Asset Index | Class Index).
- Launch Digital Index | Read Digital Index Documentation
3. iTwin Toolbox (toolbox.itwin.app)
Comprehensive analysis, ISO 19650 data hygiene indicators, and interactive ECSQL query tools for engineering teams.
- ECSQL Query Builder & Execution Plans: Construct performant ECSQL queries with live schema discovery and
PRAGMA explain_query optimization (Query Builder).
- Model Quality & Health Indicators: Audit model naming, category codification, duplicate bounding boxes, and rogue extent geometry (Quality Dashboard).
- Cross-Changeset Benchmarking: Track completeness trends and issue registers across design stages (Analysis).
