scope:

This document specifies concepts and principles to establish a methodology for specifying level of information need and information deliveries in a consistent way when using Building Information Modelling (BIM).

This document specifies the characteristics of different levels used for defining the detail and extent of information required to be exchanged and delivered throughout the life cycle of built assets. It gives guidelines for principles required to specify information needs.

The concepts and principles in this document can be applied for a general information exchange and whilst in progress, for a generally agreed way of information exchange between parties in a collaborative work process, as well as for a contractually specified information delivery.

The level of information need provides methods for describing information to be exchanged according to exchange information requirements. The exchange information requirements specify the wanted information exchange. The result of this process is an information delivery.

The concepts and principles contained in this document are applicable to all those involved in the asset life cycle. This includes, but is not limited to, the asset owner/operator, the project client, the asset manager, the design team, the construction supply chain, the equipment manufacturer, the system specialist, the regulator, and the end-user.
