Clean handover: structuring BIM documentation your FM team can actually run with.

An as-built model only the design team can navigate isn't a handover — it's a liability with a bow on it. Here's what FM-ready documentation looks like.
The gap between a design model and an FM-ready model is wider than most project teams realise, and it almost never gets addressed until the project is under programme pressure at Stage 6. By that point, the opportunity to structure the model correctly has passed, and the FM team inherits a document set that is technically compliant and practically useless.
An FM-ready model is not primarily about geometry. The geometry in an as-built model is relatively straightforward to produce — it is a record of what was built, updated from the construction model. The FM value is in the asset data attached to each object: maintenance schedules, warranty periods, manufacturer references, spare parts information, and the relationship between a model object and the physical asset in the building.
That data has to be specified before it can be delivered. An employer information requirement that does not include an asset data schema — a defined list of parameters, acceptable values, and the system those values need to be compatible with — will not produce usable FM data at handover. The contractor will deliver whatever the authoring software defaults to, which is almost never what the FM team needs.
The second piece is the CDE handover structure. The folder hierarchy and naming convention that supported design coordination does not match the query patterns of an FM team. A facilities manager looking for the maintenance manual for a specific AHU is not thinking in terms of discipline, stage, and revision — they are thinking in terms of system, floor, and asset reference. The handover CDE needs to be structured around those query patterns.
We include a handover specification in every BEP we write, agreed at Stage 2, that defines the asset data schema, the handover CDE structure, and the acceptance criteria for the as-built model. That specification becomes the basis for the Stage 6 review, and it gives the FM team a document they can use to verify what they have received rather than discovering the gaps after the design team has moved on.
