Why data not documents? Strategic: Interoperability» One format, many paths Management: Checkability» One input, many checks Authoring: Re-usability» One input, many outputs
Three Key Standards BIM is about sharing structured data. IFC Information for Construction What information can be re-used. Includes designs, processes, resources, participants. IFC STEP files and IFC XML files define portable file structures. IDM Information Delivery Manuals How specific required information exchanges can be documented. How to capture your requirements for application developers to meet. Integrates with workflow management IFD International Framework Dictionary Catalogues terms and concepts. Includes multiple languages Includes proprietary dialects such as Revit-speak, Bentley-speak
