Building information modelling — Level of information need — Part 1: Concepts and principles

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.

Modélisation des informations de la construction (BIM) — Niveau du besoin d’information — Partie 1: Concepts et principes

Le présent document spécifie les concepts et les principes permettant d’établir une méthodologie de spécification cohérente du niveau du besoin d’information et des livraisons d’information à l’aide de la modélisation des informations de la construction (BIM). Le présent document spécifie les caractéristiques des différents niveaux utilisés pour définir le détail et l’étendue des informations qu’il est nécessaire d’échanger et de livrer tout au long du cycle de vie des actifs bâtis. Il donne des lignes directrices sur les principes requis pour spécifier les besoins d’information. Les concepts et les principes énoncés dans le présent document peuvent s’appliquer à un échange général d’informations et, dans le même temps, à un mode communément accepté d’échange d’informations entre des parties dans le cadre d’un processus de travail collaboratif, ainsi qu’à une désignation accompagnée d’une livraison d’informations spécifiée. Le présent document s’applique à la totalité du cycle de vie d’un actif bâti, y compris la planification stratégique, la conception initiale, l’ingénierie, le développement, la documentation et la construction, l’exploitation quotidienne, la maintenance, la réhabilitation, la réparation et la fin de vie.
