BIM QA Assistant

IFC checks, clash reports, and compliant deliverables. Automated QA/QC assistant for BIM models that checks against standards, detects issues, and generates reports—55% faster with 100% checklist coverage.

The Challenge

An AEC firm delivering BIM models to clients faced manual, error-prone QA/QC processes. BIM coordinators spent days checking IFC compliance, running clash detection, and verifying standards across large model sets—missing issues that surfaced later in construction.

They needed an automated assistant to validate models against IFC standards, detect clashes, ensure LOD compliance, and generate comprehensive reports before client delivery, all while reducing QA turnaround time.

Our Solution

We built a Python-based QA assistant using IfcOpenShell to parse IFC models, run automated compliance checks against ISO 19650 and client standards, perform clash detection, validate LOD requirements, and generate comprehensive PDF/Excel reports with actionable findings.

Technology Stack

BIM & Validation

IfcOpenShell for IFC parsing

IFC Compliance Checks

Automated validation against IFC4, ISO 19650, and client-specific standards with detailed non-compliance reports.

Clash Detection

Automated clash detection across disciplines with severity classification and visual clash reports.

LOD Validation

Verify Level of Development (LOD) compliance for all model elements against project requirements.

Comprehensive Reports

Generate detailed PDF/Excel reports with findings, recommendations, and compliance scores for client delivery.

The Results

The BIM QA assistant dramatically reduced quality control time, improved compliance, and eliminated pre-delivery issues, leading to higher client satisfaction and faster project turnarounds.
