Twelve US companies joined the consortium.
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 1639 used collaboration format in Building information modeling BIM based projects.
Such capability allows multiple IFC files to be merged deterministically, ensuring data integrity without human intervention. IfcProject encapsulates an overall project and indicates the project name, description, default units, currency, coordinate system, and other contextual information.
IfcTypeObject captures type definitions or templates such as a product type having a particular model number and common shape. This standard has been revised by ISO While IFC defines several hundred property sets for specific types, custom property sets may be defined by application vendors or end users.
Each representation is identified by IfcShapeRepresentation with a well-known name. Monday to Friday – BIM exchange format definitions that are required during the life cycle is of buildings: This page was last edited on 26 Novemberat Processes may be assigned to products indicating the output produced by the work performed.
IfcResource is the base class for resources and is subdivided into materials, labor, equipment, subcontracts, crews, and more.
Industry Foundation Classes
A valid IFC file must always include exactly one IfcProject instance, from which all other objects relate directly or indirectly. Processes may be sequenced such that a successor task may start after a predecessor task finishes, following the Critical Path Method.
Organization and digitization of information about buildings and civil engineering works, including building information modelling BIM. IfcRelationship captures relationships among objects. The following are within the scope of ISO Building information modeling BIM.
Resources may isi assigned to processes indicating tasks performed on behalf of 1739 resource. A particular MVD is defined to support one or many recognized workflows in the construction and facility management industry sector.
A property set contains one or more properties which may be a single value e. The Industry Foundation Classes specify a data schema and an exchange file format structure.
Representations may be defined for explicit 3D shape, and optionally as parametric constraints.

Proof sent to secretariat or FDIS ballot initiated: Processes may be nested into sub-processes for summary roll-up. At the most abstract level, IFC divides all entities into rooted and non-rooted io. Materials may be defined for products as a whole, or as layers, profiles, or constituents for specified parts.
Final text received or FDIS registered for formal approval. The data schema is defined in. Each workflow identifies data exchange requirements for software applications.
Check out our FAQs. This release, and upcoming releases, extend the scope to include data definitions for infrastructure assets over their life cycle as well. Because of its focus on ease of interoperability between software platforms, the Danish government has made the use of IFC format s compulsory for publicly aided building projects.
Rooted entities derive from IfcRoot and have a concept of identity having a GUIDalong with attributes for name, description, and revision control. It is a platform neutral, open file format specification that is not controlled by isso single vendor or group of vendors. From Wikipedia, the free encyclopedia.
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.
Monday to Friday – Conforming software applications need to identity the model view definition they conform to. IfcObject captures object occurrences such as a product installation having serial number and physical placement. 1673
IFC defines multiple file formats that may be used, supporting various encodings of the same underlying data.
Resources may have various costs and calendars of availability. IFC defines various quantities specific to each element type and the method of calculation according to geometry and relationships.

IFC4 as ISO standard — Welcome to
Processes may have durations and be scheduled to occur at specific time periods. The IFC model specification is open and available. Life cycle A standard is reviewed every 5 years 00 Preliminary. There are five fundamental relationship types: Occurrences and types are further subdivided into six fundamental concepts:
