Handover is not a last-minute export

Digital handover often fails when operational data is treated as an appendix. The model is delivered, spreadsheets are added, and operations teams then have to reconstruct information they cannot use directly.

A reliable handover starts earlier. It defines required information, data-entry responsibilities, expected formats and the checks that must be completed before delivery.

Information to stabilise

Asset and space identification.
Maintenance properties: type, manufacturer, reference, status, location and criticality.
Classifications aligned with the owner's reference system.
Data that can be exported to a spreadsheet, FM tool or COBie where required.
A trace of issues and corrections before handover.

The role of the IFC audit

An IFC audit checks that data is not merely present but actually usable. It identifies empty fields, inconsistent values, duplicates and incorrectly typed objects. It also creates an audit trail: what was checked, what is missing and what must be corrected.

That traceability matters to operations teams because they do not have to rely on implicit trust in a delivered file. The data becomes verifiable.

A use-oriented handover

A successful handover is not the most complete model possible. It is data that is sufficiently clear, controlled and useful for the intended operations. Requirements should remain proportional: too little information creates debt, while too much unmaintained information creates noise.

The right approach is to define use cases, check critical information, document issues and deliver a package that operational teams can genuinely take over.
