The following are within the scope of ISO This standard has been revised by ISO The standard includes definitions that cover data required for buildings over their life cycle.

This article’s use of external links may not follow Wikipedia’s policies or guidelines. The Industry Foundation Classes specify a data schema and an exchange file format structure.

Check out our FAQs. Life cycle A standard is reviewed every 5 years 00 Preliminary. Final text 17639 or FDIS registered for formal approval.

A particular model view definition is defined to support one or many recognized workflows in the building construction and facility management industry sector. Each representation is identified by IfcShapeRepresentation with a well-known name.

IfcProject encapsulates an overall project and indicates the project name, description, default units, currency, coordinate system, and other contextual information.

Industry Foundation Classes – Wikipedia

IfcObjectDefinition is split into object occurrences and object types. IfcRoot is subdivided into three abstract concepts: This page was last edited on 26 Novemberat While IFC defines several hundred property sets for specific types, custom property sets may be defined by application vendors or end users. Processes may be sequenced such that a successor task may start after a predecessor task finishes, following the Critical Path Method. Products may have associated materials, shape representations, and placement in space.


Proof sent to secretariat or FDIS ballot initiated: Twelve US companies joined the consortium.

Alternative exchange file formats can be used if they conform to the conceptual schema. 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. BIM exchange format definitions that are required during the life cycle phases of buildings: 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 167399 participants in the construction or facility management 61739 sector.

There are five fundamental relationship types: Views Read Edit View history. Projects support revision control where any 167399 entity has a unique identifier and may be marked as added, modified, deleted, or having no change.

Please improve this article by removing excessive or inappropriate external links, and converting useful links where appropriate into footnote references. Materials may be defined for products as a whole, or as layers, profiles, or constituents for specified parts.

A particular MVD is defined to support one or many recognized workflows in izo construction and 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. IfcPropertyDefinition captures dynamically extensible property sets.


Industrial computing Building Building information modeling. Please ixo this by adding secondary or tertiary sources. Retrieved from ” https: A valid IFC file must always include exactly one IfcProject instance, from which all other objects relate directly or indirectly.

Processes may be nested into sub-processes for summary roll-up. The following are outside the scope of ISO Wikipedia external links cleanup from March Wikipedia spam cleanup from March Articles lacking reliable references from March All articles lacking reliable references.

Each workflow identifies data exchange requirements for software applications. From Wikipedia, the free encyclopedia. Rooted entities derive from IfcRoot and have a concept of identity having a GUIDalong with attributes for name, description, and revision control. Conforming software applications need to identity the model view definition they conform to. Occurrences and types are further subdivided into six fundamental concepts: IFC defines various quantities specific to each element type and the method of calculation according to geometry and relationships.

Conforming software applications need to identity the model view definition they conform to. Various connectivity relationships are used for building elements such as walls having openings filled by doors or windows.

IfcResource is the base class for resources and is subdivided into materials, labor, equipment, subcontracts, crews, and more.
