Building information models — Information delivery manual — Part 1: Methodology and format
ISO 29481-1:2016 specifies - a methodology that links the business processes undertaken during the construction of built facilities with the specification of information that is required by these processes, and - a way to map and describe the information processes across the life cycle of construction works. ISO 29481-1:2016 is intended to facilitate interoperability between software applications used during all stages of the life cycle of construction works, including briefing, design, documentation, construction, operation and maintenance, and demolition. It promotes digital collaboration between actors in the construction process and provides a basis for accurate, reliable, repeatable and high-quality information exchange.
Modèles des informations de la construction — Protocole d’échange d’informations — Partie 1: Méthodologie et format
L'ISO 29481-1:2016 spécifie: - une méthodologie qui relie les processus métier employés pendant la construction d'installations à la spécification des informations requises par ces processus; et - un moyen de cartographier et de décrire les processus d'information sur tout le cycle de vie des travaux de construction. L'ISO 29481-1:2016 est destinée à faciliter l'interopérabilité entre les applications logicielles utilisées à toutes les étapes du cycle de vie des travaux de construction, dont la préparation, la conception, la documentation, la construction, l'exploitation et la maintenance, ainsi que la déconstruction. Elle promeut la collaboration numérique entre les acteurs du processus de construction et donne une base pour un échange d'informations précis, fiable, répétable et de haute qualité.

Introduction
This document specifies the format used to present the exchange requirements for a use case and its
associated business processes. This is referred to as an information delivery manual (IDM) since it precisely
defines the “information delivery” requirements of the use case, recording those using natural language in a
“manual” that can be understood by all stakeholders. An IDM consists of three components: the use case
description, the business context and specified exchange requirements.
IDMs can be used to solve commonplace problems associated with communication between different parties
in project teams or asset management teams by ensuring the clarity of and responsibility for information. An
IDM helps all parties get the full benefits from any information model by understanding how the information
will be used. If the required information is delivered in a reliable format to support different purposes across
the life of an asset and the quality of the information is satisfactory, then the use cases and associated business
processes will be greatly improved.
This document provides a methodology that begins by identifying a use case, then defines the business context
and its associated business processes using recommended mapping techniques to finally arrive at a detailed
specification of the required exchange requirements between parties at specific times during those business
processes.
This IDM methodology has been developed specifically for the built environment sector concerned with all
aspects of the delivery and management of assets. These activities can be both contractual (such as asset
delivery) and non-contractual (such as regulatory compliance) between all stakeholders within the built
environment sector and across the whole asset life cycle.
IDM development can be streamlined in various ways as described in Annex AAnnex A. This document also
includes a brief overview of technical implementations of IDMs to support solutions provided by software
developers, and how an IDM can be configured to meet national, local and project needs.
It is often assumed that information delivery would be achieved using an information model – represented
using industry foundation classes (IFC) – and conforming to an information delivery specification to satisfy
the exchange requirements. This document significantly broadens that assumption to include any information
formats that can satisfy (in whole or in part) the exchange requirements for a given business process.
Additional standards have been published in support of information management and building information
modelling. Figure 1Figure 1 shows the position of this document within the context of these other standards.
The ISO 19650 series set out general concepts and principles for information management throughout the
whole asset life cycle, as well as specific requirements to manage information during project delivery or asset
management. It also specifies an approach for achieving information security in a collaborative working
environment and sets out criteria to be used to assess the quality of information deliverables.
The ISO 19650 series and the ISO 29481 series use the same terminology wherever possible. The IDM
specification in this document is the appropriate way to record the relationships between types of actors that
fulfil the party roles named in the ISO 19650 series and sets out the detailed information that one type of
organization requires from another.
The exchange requirements defined in an IDM specify in detail the information that is required but does this
in terms of generic actor types (e.g. what a client requires from a designer for a given business process). This
is different to the exchange information requirement described in the ISO 19650 series: it is specific to a given
appointment (e.g. what the client for project XYZ requires from their designer on that project) and the
information may be defined in whatever level of detail is deemed appropriate. This means it is possible for
one exchange information requirement to correlate to multiple exchange requirements.
v
The business context established as part of an IDM can also help define the information management
resources used in the ISO 19650 series, such as the information standard and the information production
methods and procedures. An IDM can be considered as a toolkit for information managers to identify what
information should be received or sent, the actors involved, how that information flows, for what purpose and
the milestones for pre-defined use cases.
Figure 1 — Relationships between ISO 29481-1 and other relevant standards
Working anticlockwise from the top-left in Figure 1Figure 1,, ISO 12911 defines a systematic approach for
developing information management documents as structured specifications to support the automated
checking of expected outcomes. The IDM specification in this document can be used to provide content for ISO
12911.

Avant-propos
L’ISO (Organisation internationale de normalisation) est une fédération mondiale d’organismes nationaux
de normalisation (comités membres de l’ISO). L’élaboration des Normes internationales est en général
confiée aux comités techniques de l’ISO. Chaque comité membre intéressé par une étude a le droit de faire
partie du comité technique créé à cet effet. Les organisations internationales, gouvernementales et non
gouvernementales, en liaison avec l’ISO participent également aux travaux. L’ISO collabore étroitement avec
la Commission électrotechnique internationale (IEC) en ce qui concerne la normalisation électrotechnique.
Les procédures utilisées pour élaborer le présent document et celles destinées à sa mise à jour sont
décrites dans les Directives ISO/IEC, Partie 1. Il convient, en particulier, de prendre note des différents
critères d’approbation requis pour les différents types de documents ISO. Le présent document
a été rédigé conformément aux règles de rédaction données dans les Directives ISO/IEC, Partie 2
(voir www.iso.org/directives).

pas reçu notification qu’un ou plusieurs brevets pouvaient être nécessaires à sa mise en application.
Toutefois, il y a lieu d’avertir les responsables de la mise en application du présent document que des
informations plus récentes sont susceptibles de figurer dans la base de données de brevets, disponible à
l’adresse www.iso.org/brevets. L’ISO ne saurait être tenue pour responsable de ne pas avoir identifié de tels
droits de brevet.
