From Revit Model to Handover Data: A COBie Workflow Walkthrough

Every project team eventually reaches the same moment: the building is built, and someone has to turn a large BIM model into information the owner can run a facility with. This walkthrough follows that path step by step, using COBie as the exchange format.

Step 1: Decide what the owner needs

COBie works best when requirements are set at the start. Teams that agree early on which assets, attributes and classifications matter can build the model with the end in mind. Writing those requirements into the BIM execution plan means designers, contractors and suppliers all know what to supply and when.

Step 2: Build the model with data in mind

A native BIM model holds geometry and engineering data in great volume. COBie only needs the part that serves operations. That makes model quality the deciding factor, because the spreadsheet can only report what the model contains. When teams look into BIM for facility management, the lesson is usually the same: asset attributes added during modeling save far more effort than data chased down after construction.

Step 3: Capture data progressively

Instead of collecting everything at closeout, COBie data is gathered as the project moves from design to construction to commissioning. Subcontractors and suppliers add manufacturer names, model numbers and serial numbers as products are chosen and installed. This progressive capture reduces transcription errors and lost information.

Step 4: Verify the workbook

Before handover, the team checks that the tabs are complete and consistent. Floors and spaces should exist before components refer to them. Each component should belong to a type and sit in a space. Systems should list the components that make them up. A few minutes spent on these relationships prevents days of cleanup later.

Step 5: Deliver and import

The finished spreadsheet goes to the owner, who imports it into a CMMS or CAFM system. From that point the facility team has locations, warranties, spare parts lists and preventive maintenance schedules from day one, rather than a pile of paper manuals.

Step 6: Keep the data alive

The delivered file is a snapshot of the as-built condition. Facility teams are expected to update it with maintenance records, replacements and refurbishments so that it remains an accurate asset register.
