Please improve this by adding secondary or tertiary oso. Distribution elements HVACelectricalplumbing have a concept of ports where elements may have specific connections for various services, and connected together using cables, pipes, or ducts to form a system.

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. Final text received or FDIS registered for formal approval.

Resources may be assigned to processes indicating tasks performed on behalf of a resource. IfcObjectDefinition is split into object occurrences and object types.

The standard includes definitions that cover data required for buildings over their life cycle. Occurrences and types are further subdivided into six fundamental concepts: From Wikipedia, the free encyclopedia. The Industry Foundation Classes specify a data schema and an exchange file format structure. BIM exchange format definitions that are required during the life cycle phases of buildings: Processes may be assigned to products indicating the output produced by the work performed.


Organization and digitization of information about buildings and civil engineering works, including building information modelling BIM. The IFC model specification is open and available. A valid IFC file must always include exactly one IfcProject instance, from which all other objects relate directly or indirectly. Alternative exchange file formats can be used isp they conform to the conceptual schema.

Check out our FAQs. A subset of the data schema and referenced data is referred to as a model view 16379. Conforming software applications need to identity the model view definition they conform to.

Industry Foundation Classes – Wikipedia

IFC defines various quantities specific to each element type and the method of calculation according to geometry and relationships. Each representation is identified by IfcShapeRepresentation with a well-known name.

IfcPropertyDefinition captures dynamically extensible property sets. Final text received or FDIS registered oso formal approval. Wikipedia external links cleanup from March Wikipedia spam cleanup from March Articles lacking reliable references from March All articles lacking reliable references.

At the most abstract level, IFC divides all entities into rooted and non-rooted entities. Building information modeling BIM.

Processes may be nested into sub-processes for lso roll-up. Each workflow identifies data exchange requirements for software applications.

A particular MVD is defined to support one or many recognized workflows in the construction and facility management industry sector. The data schema is defined in. A particular model view definition is defined to ixo one or many recognized workflows in the building construction and facility management industry sector. Resources may have various costs and calendars of availability. Resources may be nested into sub-resources for granular allocation. IfcProcess is the base class for processes and is subdivided into tasks, events, and procedures.
