These are complementary approaches and are explained in further detail in later sections. Within a given business context, it may be appropriate to use both methodologies: process mapping can be used to clarify the details of a transaction identified in an interaction mapping exercise, while an interaction map can be used to rigorously understand an information transaction defined in a process map.
Where the information requirements are satisfied by a BIM, a complete information schema that covers all of the information required for all actors throughout the construction process will be large and comprehensive. Such a schema is relevant in defining all of the project information needs for all business processes at all life cycle stages, but it is not the way that project information is usually delivered.
It is more usual for information to be exchanged about a particular topic and the level of detail provided to be driven by the life cycle stage. This may be a single business process at a specific point in the project life cycle, but commonly consists of information units that may be relevant to more than one life cycle stage or business processes. This is commonly referred to as a model view and is a matter of deciding which components of the information schema should be used to meet requirements.
Elements of the overall information schema are used in a building information model (see Figure 2). For a particular business process, 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). The classes that support the business process form a unique and identifiable standard schema or model view.AS ISO 29481.1 pdf free download.
