IFC and COBie
COBie (Construction-Operations Building Information Exchange) is the facility-management handover dataset: the non-graphic data an owner needs to populate a maintenance and asset-management system. In IFC terms COBie is a MODEL VIEW DEFINITION SUBSET, realised as the Basic FM Handover View. It captures spaces, zones, components, types, systems, spares, resources, jobs, documents, and attributes. It is NOT a geometry format.
This skill covers the COBie worksheet to IFC entity map, the IFC2x3 and IFC4 bindings, the STEP versus spreadsheet exchange forms, and extracting a COBie subset from a full model.
Verified against the buildingSMART MVD database and the IFC 4.3.2 specification (ISO 16739-1:2024). The Basic FM Handover View is verified as an IFC2x3 TC1 MVD with status Final. COBie applies to IFC2x3, IFC4, IFC4.3.
