What Is COBie in Construction?

COBie stands for Construction Operations Building information exchange. It is a structured way to deliver non-geometric information about spaces, systems, equipment and related documents for building operation and maintenance.

Is COBie a 3D model?

No. A model can help supply information, but COBie focuses on usable asset data: for example, a maintainable component’s identity, type, location, manufacturer and associated records. The owner needs to define which fields and assets matter to its facilities system. A spreadsheet full of blanks or invented values does not become useful simply because it follows a template.

When should the data be collected?

Agree requirements at briefing and procurement. Designers may establish spaces and systems; suppliers and contractors contribute installed equipment details; commissioning and handover confirm what was actually delivered. Assign each field to a responsible party and set validation points through the project.

What should the owner check?

Test whether asset IDs match physical labels, locations, manuals and maintenance records. Check mandatory fields, duplicate entries, document links and import requirements with the operator before final acceptance. The contract should state the agreed exchange format and acceptance criteria.

Start with a sample asset list rather than demanding every conceivable data field. If the facilities team maintains pumps and air-handling units in a specific system, test a small import with real labels and manuals. That reveals naming and format issues while they are still fixable.

COBie is valuable when the owner can use the information after handover. See the broader handover checklist or talk to Team Vanguard about asset data.
