IfcTypeObject captures type definitions or templates such as a product type having a particular model number and common shape.

In addition 1639 project-specific information, an IfcProject may also reference external 1679 from which shared definitions may be imported such as product types. At the most abstract level, IFC divides all entities into rooted and non-rooted entities.

Monday to Friday – The Industry Foundation Classes, IFC, are an open international standard for Building Information Model BIM data that are exchanged and shared among software applications used by the various participants in the construction or facility management industry sector.

The standard exchange file format for exchanging and sharing data according to the conceptual schema is using the Clear text encoding of the exchange structure.

Organization and digitization of information about buildings and civil engineering works, including building information modelling BIM. Views Read Edit View history. Processes may be assigned to products indicating the output produced by the work performed. Projects support revision control where any 1739 entity has a unique identifier and may be marked as added, modified, deleted, or having no change. The following are within the scope of ISO A particular MVD is defined to support one or many recognized workflows in the construction and facility management industry sector.


The Industry Foundation Classes specify a data schema and an exchange file format structure. It is an object-based file format with a data model developed by buildingSMART formerly the International Alliance for Interoperability, IAI to facilitate interoperability in the architectureengineering and construction AEC industry, and is a commonly used collaboration format in Building information modeling BIM based projects.

IfcResource is the 167739 class for resources and is subdivided into materials, labor, equipment, subcontracts, crews, and more. IfcRelationship captures relationships among objects. Non-rooted entities do 167739 have identity and instances isl exist if referenced from a rooted instance directly or indirectly.

IfcObject captures object occurrences such as a product installation having serial number and physical placement. Check out our FAQs.

Each workflow identifies data exchange requirements for software applications. It is a platform neutral, open file format specification that is not controlled by a single vendor or group of vendors. IFC defines multiple file formats that may be used, supporting various encodings of the same underlying data.

Rooted entities derive from IfcRoot and have a concept of identity having a GUIDalong with attributes for name, description, and revision control.

Materials may be defined for products as a whole, or as layers, profiles, or constituents for specified parts. Conforming software applications need to identity the model view definition they conform to. This article’s use of external links may not follow Wikipedia’s policies or guidelines.

IFC4 as ISO standard — Welcome to

Because of its focus on ease of interoperability between software platforms, the Danish government has made the use of IFC format s compulsory for publicly aided building projects. Processes may be sequenced such that a successor task may start after a predecessor task finishes, following the Critical Path Method. This standard has been revised by ISO Life cycle A standard is reviewed every 5 years 00 Preliminary.
