IFC traces back to 1994, when Autodesk invited twelve US companies to advise on a common set of C++ classes for building software interoperability \u2014 the effort that became the International Alliance for Interoperability (IAI), opened to all members in 1995. The IAI published IFC 1.0 in 1997, and the standard has been revised through IFC2x, IFC4, and the current IFC4.3 (which added infrastructure \u2014 roads, bridges, rail \u2014 to the original buildings-only scope). In 2005 the organization renamed itself buildingSMART, which still maintains IFC today as an ISO standard (ISO 16739) alongside its own certification program for software vendors.<\/p>
What makes IFC matter for a DAM is precisely what makes it different from a proprietary CAD format: no single vendor controls it, so a model exported to IFC from Revit can be opened, checked, and coordinated in ArchiCAD, Solibri, or a free viewer without licensing Autodesk software. AEC firms are a real DAM vertical distinct from photo or video asset management \u2014 architecture and engineering teams need the same governed storage, versioning, and search applied to building models, drawings, and site documentation \u2014 and IFC is the format that lets a DAM store one archival copy of a building model that stays usable regardless of which authoring tool produced it or which tool a downstream consultant uses.<\/p>","protected":false},"excerpt":{"rendered":"
