Rooted entities derive from IfcRoot and have 1739 concept of identity having a GUIDalong with attributes for name, description, and revision control.

This page was last edited on 26 Novemberat IfcObject captures object occurrences such as a product installation having serial number and physical placement. Check out our FAQs. A property set contains one or more properties which may be a single value e. Monday to Friday – IfcProduct is the base class for all physical objects and is subdivided into spatial elements, physical elements, structural analysis items, and other concepts.

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.

Life cycle A standard is reviewed every 5 years 00 Preliminary. While IFC defines several hundred property sets for specific types, custom property sets may be defined by application vendors or end users.

A valid IFC file must always include exactly one IfcProject instance, from which all other objects relate directly or indirectly. From Wikipedia, the free encyclopedia.

Final text received or FDIS registered for formal approval. Each workflow identifies data exchange requirements for software applications.

Alternative exchange file formats can be used if they conform to the conceptual schema. Resources may be nested into sub-resources for granular allocation. Industrial computing Building Building information modeling. Check out our FAQs. IfcObjectDefinition is split into object occurrences and object types.

Processes may be assigned to products indicating the output produced by the work performed.

Products may have associated materials, shape representations, and placement in space. March Learn how and when to remove this template message. IFC defines multiple file formats that may be used, supporting various encodings of the same underlying data. Each representation is identified by IfcShapeRepresentation with a well-known name.


IfcRelationship captures relationships among objects. IfcPropertyDefinition captures dynamically extensible property sets. Such capability allows multiple IFC files to be merged deterministically, ensuring data integrity without human intervention. Non-rooted entities do not have identity and instances only exist if referenced from a rooted instance directly or indirectly.

Processes may have durations and be scheduled to occur at specific time periods. Monday to Friday – Organization and digitization of information about buildings and civil engineering works, including building information modelling BIM. Final text received or FDIS registered for formal approval. Processes may be sequenced such sio a successor task may start after a predecessor task finishes, following the Critical Path Method. IfcProcess is the base isp for processes and is subdivided into tasks, events, and procedures.
