Building Information Modelling - Level of Information Need - Part 1 Concepts and principles (ISO 7817-1:2024)
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 while in progress, for a generally agreed way of information exchange between parties in a collaborative work process, as well as for an appointment with specified information delivery.
This document is applicable to the whole life cycle of any built asset, including strategic planning, initial design, engineering, development, documentation and construction, day-to-day operation, maintenance, refurbishment, repair and end-of-life.

ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.

described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted (see www.iso.org/directives).

Introduction
This document sets out the concepts and principles for defining the level of information need and
information deliveries being part of the information exchange processes during the life cycle of built
assets when using building information modelling (BIM). Those concepts and principles can deliver
clear benefits to all participants in the various life cycle phases of built assets as they provide a common
understanding on the right level of information needed at a certain time. One purpose of defining the
level of information need is to prevent delivery of too much information. Information exchange should
ensure the required information to be delivered at the agreed time for the agreed purpose to facilitate
verification and validation processes.
This document 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.
There is a need that these concepts and principles are described in a common and comparable way to
allow services related to building information modelling to be procured and offered on a global scale.
The need has arisen by the fact that there are several conflicting terms, concepts and usages in place,
internationally, that hinder the objective of having a common understanding and practise in describing
the level of information need. It is therefore helpful not to use an acronym to refer to level of information
need as this can oversimplify these concepts.
The concepts and principles contained in this document are aimed at all those involved in the asset life
cycle. This includes, but is not limited to, the asset owner/operator, the client, the asset manager, the
design team, th
