Why audit before coordination

BIM coordination often starts when teams are focused on clashes, openings and graphical synthesis. Yet an IFC model can look perfectly readable while remaining difficult to use: objects exported as proxies, missing properties, inconsistent units or classifications stored as free text.

An IFC audit before coordination prevents this data debt from spreading. It does not replace discipline-specific review, but it stabilises the data foundation used by consultants, BIM managers and owners for decisions.

Priority checks

Verify that the main objects use appropriate IFC entities: walls, slabs, doors, windows, equipment and spaces.
Check the Psets required by the project: fire rating, load-bearing status, U-value, phase, status, cost code or FM information.
Identify empty, duplicated or incorrectly located properties.
Validate units, areas and volumes when they feed quantities or handover.
Identify missing or unstable eCCC-Bât / CFC classifications.

What a useful audit produces

A good report does not simply state whether the model is compliant. It isolates issues, assigns severity and gives a clear corrective action. BCF can then transmit model-related issues directly into coordination tools without losing context.

For an owner, the benefit is straightforward: data becomes controllable. For an engineering team, corrections are targeted and prioritised. For operations, this is the minimum foundation for a reliable digital handover.

The right moment

The best time to audit is not the day before delivery. A light check before coordination, followed by a more complete check before handover, avoids late corrections. IFC auditing should be treated as a quality step, not as a final sanction.
