IFC stands for Industry Foundation Classes. It is an open standard that has been created by the international organization buildingSMART, which can be defined as a “standardized, digital description of the built environment” (buildingSMART). More specifically, it is an object format for open Building Information Modeling (BIM) data exchange and aims to facilitate interoperability. IFC can be used either to exchange information from one stakeholder to another, as a means of archiving project information (during the design, procurement , and construction phases), or as an “as-built” collection of information.
