A property set contains one or more properties which may be a single value e. IfcRelationship captures relationships among objects. IfcTypeObject captures type definitions or templates such as a product type having a particular model number and common shape. IFC defines multiple file formats that may be used, supporting various encodings of the same oso data. The sio are outside the scope of ISO Rooted entities derive from IfcRoot and have a concept of identity having a GUIDalong with attributes for name, description, and revision control.

This release, and upcoming releases, extend the scope to include data definitions for infrastructure assets over their life cycle as well. This article’s use of external links may not follow Wikipedia’s policies or guidelines. IfcProduct is the base class for all physical objects and is subdivided into spatial elements, physical elements, structural analysis items, and other concepts. Check out our FAQs. Views Read Edit View history. Building information modeling BIM.

From Wikipedia, the free encyclopedia. Organization and digitization of information about buildings and civil engineering works, including building information modelling BIM. 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.


Each workflow identifies data exchange requirements for software applications. Processes may have durations and be scheduled to occur at specific time periods.

In addition to project-specific information, an IfcProject may also reference external projects from which shared definitions may be imported such as product types. 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.

BIM exchange format definitions that are required during the life cycle phases of buildings: Twelve US companies joined the consortium. A valid IFC file must always include exactly one IfcProject instance, from which all other objects relate directly or indirectly. Check out our FAQs. There are five fundamental relationship types: Resources may have various costs and calendars of availability. Products may have associated materials, shape representations, and placement in space.

IFC4 as ISO standard — Welcome to

A particular MVD is defined to support one or many recognized workflows in the construction and facility management industry sector.

This standard has been revised by ISO The standard includes definitions that cover data required for buildings over their life cycle. At the most abstract level, IFC divides all entities into rooted and non-rooted entities. Retrieved from ” https: Projects support revision control where any IfcRoot-based entity has a unique identifier and may be marked as added, modified, deleted, or having no change.

March Learn how and when to remove this template message. While IFC defines several hundred property sets for specific types, custom property sets may be defined by application vendors or end users.


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.

Materials may be defined for products as a whole, or as layers, profiles, or constituents for specified parts. The IFC model specification is open and ios. IfcResource is the base class for resources and is subdivided into materials, labor, equipment, subcontracts, crews, and more. Life cycle A standard is reviewed every 5 years 00 Preliminary. Processes may be assigned to products indicating the output produced by the work performed.

IfcPropertyDefinition captures dynamically extensible property sets. The Industry Foundation Classes specify a data schema and an exchange file format structure.

Final text received or FDIS registered jso formal approval. This article relies too much on references to primary sources. IFC defines various quantities specific to each element type and the method of calculation according to geometry and relationships.

IfcObject captures object occurrences iiso as a product installation having serial number and physical placement. A subset of the data schema and referenced data is referred to as a model view definition. Final text received or FDIS registered for formal approval.
