  • Introduction
    to support one or many recognized work flows in the building construction and facility management industry sector Each work flow identifies data exchange requirements that are to be supported by the conforming software applications buildingSMART International publishes official model view definitions and exchange requirements as related specifications The official website for publication of this specification related model view definitions and exchange requirements and supporting materials such as implementer agreements example data sets references to development tools discussion forum and issue database and certification programs is http www buildingSMART tech org The IFC specification includes terms concepts and data specification items that originate from use within disciplines trades and professions of the construction and facility management industry sector Terms and concepts uses the plain English words the data items within the data specification follow a naming convention the data item names for types entities rules and functions start with the prefix Ifc and continue with the English words in CamelCase naming convention no underscore first letter in word in upper case the attribute names within an entity follow the CamelCase nameing convention with no prefix the property set definitions that are part of this standard start with the prefix Pset and continue with the English words in CamelCase naming convention the quantity set definitions that are part of this standard start with the prefix Qto and continue with the English words in CamelCase naming convention The data schema architecture of IFC defines four conceptual layers each individual schema is assigned to exactly one conceptual layer Figure 1 shows the schema architecture Figure 1 Data schema architecture with conceptual layers Resource layer the lowest layer includes all individual schemas containing resource definitions those definitions do not include an globally unique identifier and shall not be used independently of a definition declared at

  • Scope
    and shared among software applications used by the various participants in a building construction or facility management project This release of IFC consists of the data schema represented as an EXPRESS schema specification and alternatively as an XML schema specification and reference data represented as definitions of property and quantity names and descriptions A subset of the data schema and referenced data is referred to as a model view definition A particular model view definition is defined to support one or many recognized workflows in the building construction and facility management industry sector Each workflow identifies data exchange requirements for software applications Conforming software applications need to identity the model view definition they conform to The following are within the scope of this release of IFC BIM exchange format definitions that are required during the life cycle phases of buildings demonstrating the need conception of need outline feasibility substantive feasibility study and outline financial authority outline conceptual design full conceptual design coordinated design procurement and full financial authority production information construction operation and maintenance BIM exchange format definitions that are required by the various disciplines involved within the life cycle phases architecture building service structural engineering procurement construction planning facility
