eCCC-Bât and CFC: make classifications usable in IFC

Swiss classifications become genuinely useful when they are carried structurally by objects, rather than written only in labels.

A code should not remain a comment

In a BIM model, a CFC or eCCC-Bât code can be present without being truly usable. It may be entered in an object name, a free property or a software-specific convention. That may work for human reading, but it limits automated checks and reliable exports.

A quality audit asks whether classification is structured, stable and coherent with the object. The data should be filterable, comparable and transferable without depending on manual interpretation.

What to verify

  • The code is attached to the relevant object, not only to a group or label.
  • The classification source is identifiable: CFC, eCCC-Bât or another reference.
  • The format is consistent throughout the model.
  • Multi-position mappings are documented when an object relates to several work packages.
  • Values are coherent with the IFC element type.

Why this matters to the owner

Clean classification supports quantities, cost analysis, work-package comparison and preparation of operational data. It also avoids rebuilding spreadsheets manually at the end of the project.

For a BIM manager, structured classification simplifies control: objects without codes, inconsistent codes or elements assigned to the wrong category can be isolated automatically.

A progressive approach

Not every project needs the same level of detail. Classification depth should match the intended use: coordination, estimation, operations or handover. An audit can start with critical families and expand as the model matures.
