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. Alternative exchange file formats can be used if they conform to the conceptual schema. ISO represents an open international standard for BIM data that is exchanged and shared among software applications used by the various participants in a building construction or facility management project.
ISO consists of the data schema, represented as an EXPRESS 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. Check out our FAQs. This standard has been revised by ISO The following are within the scope of ISO 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 management; project management; client requirement management; building authority for permits and approval; BIM exchange format definitions including: project structure; physical components; spatial components; analysis items; processes; resources; controls; actors; context definition.
The following are outside the scope of ISO exchange format definitions outside of the domain of construction and facility maintenance; project structure and component breakdown structures outside of building engineering; behavioral aspects of components and other information items.

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. The standard includes definitions that cover data required for buildings over their life cycle. This release, and upcoming releases, extend the scope to include data definitions for infrastructure assets over their life cycle as well. The Industry Foundation Classes specify a data schema and an exchange file format structure.
The Industry Foundation Classes IFC data model is intended to describe architectural, building and construction industry data. It is a platform neutral, open file format specification that is not controlled by a single vendor or group of vendors. 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 architecture , engineering and construction AEC industry, and is a commonly used collaboration format in Building information modeling BIM based projects. The IFC model specification is open and available. 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. Twelve US companies joined the consortium.
