IFC audit in Switzerland — quality control before coordination and handover

Verify that an IFC model is genuinely usable: correctly typed entities, required properties, coherent Swiss classifications and traceable deliverables.

By Winter Fernandes · Updated 5 August 2026

Why audit an IFC model

A model may display correctly while remaining unusable for downstream work. Proxies, missing properties, inconsistent units and free-text classifications are data issues that visual inspection alone cannot secure.

The audit measures the gap between the delivered model and the project's actual requirements, then turns that gap into actions for the project team.

Priority checks

  • IFC entity typing and excessive proxies.
  • Required Psets, properties and values.
  • Units, areas, quantities and spatial structure.
  • eCCC-Bât / CFC classifications and IDS requirements.
  • Issues that affect coordination, handover or operations.

Actionable deliverables

The result combines a decision-level summary, a detailed issue table and, where useful, BCF issues that can be reopened in BIM coordination tools.

Frequently asked questions

When should an IFC audit be performed?

Ideally before major coordination and again before final handover, so data issues are corrected while the project can still absorb them.

Does the audit modify the source model?

No. The audit identifies and documents discrepancies; corrections remain with the responsible authoring teams unless a separate scope is agreed.

Can IDS be included?

Yes, when an IDS specification or sufficiently clear information requirements are available.
