8 Needs. In doing so, it provides a basis for reliable information exchange/sharing for users so that they can be confident that the information they are receiving is accurate and sufficient for the activities they need to perform. It is reliability that users need in information exchange and that motivates this standard. Terms and definitionsBuilding Construction Information Model BIM A shared digital representation of physical and functional characteristics of any built object including buildings, bridges, roads, process plants etc.

9 Forming a reliable basis for decisions NOTE Building Information Model is frequently used as a synonymfor BIM buildingSMART s framework of BIMexchange requirement ER The set of information that needs to be exchanged to support a particular business requirement at a particular process stage (or stages)process map PM A representation of the relevant characteristics of a process for a defined purposefunctional part FP A unit of information within an exchange requirement that may be fully specified in its own right business rule A statement that formally defines or constrains some aspect of the business.

10 A rule under which an organisation operates or a policy or decision that influences a process What is the IDM The Information Schema supports all business requirements at all lifecycle stagesNeed to support a business requirement at a lifecycle stage Elements of the overall information schema are used in a BIM. For a particular business requirement, only certain classes of information are required. Multiple objects are derived from each class, each object having an identity (determined by a unique identifier) and a state (determined by the values given to each attribute of the object).
