Building information models — Information delivery manual — Part 2: Interaction framework
ISO 29481-2:2012 specifies a methodology and format for describing ?coordination acts' between actors in a building construction project during all life cycle stages. It therefore specifies a methodology that describes an interaction framework, an appropriate way to map responsibilities and interactions that provides a process context for information flow, a format in which the interaction framework should be specified. ISO 29481-2:2012 is intended to facilitate interoperability between software applications used in the construction process, to promote digital collaboration between actors in the building construction process, and to provide a basis for accurate, reliable, repeatable, and high-quality information exchange.
Modèles des informations de la construction — Protocole d’échange d’informations — Partie 2: Cadre d’interaction
L'ISO 29481-2:2012 spécifie une méthodologie et un format de description des «actions de coordination» entre les acteurs d'un projet de construction à toutes les étapes du cycle de vie. Par conséquent, elle spécifie: - une méthodologie qui décrit un cadre d'interaction; - une manière adaptée d'identifier les responsabilités et les interactions, qui donne un contexte aux flux d'informations du processus; - un format dans lequel il est recommandé de spécifier le cadre d'interaction. L'ISO 29481-2:2012 est destinée à faciliter l'interopérabilité entre les logiciels utilisés dans le processus de construction, afin de promouvoir la collaboration numérique entre les acteurs du processus de construction et de fournir une base pour un échange d'informations précis, fiable, répétable et de haute qualité.

Introduction
Collaboration between the participants involved during the life cycle of assets is pivotal to the efficient
delivery and operation of assets. Organizations collaborate within specific use cases to achieve higher levels
of quality and greater re-use of existing knowledge, information experience and resources. A significant
condition of collaboration is the opportunity to communicate, re-use and share information efficiently, and to
reduce the risk of loss, contradiction or misinterpretation.
The ISO 29481 series on the information delivery manual (IDM) provides significant assistance in making the
most of information management. If the necessary information is available at the right time, the quality of the
information is satisfactory and the right person is involved at the right time, the collaboration and outcome
itself is greatly improved. Since management and coordination rely heavily on communication, it benefits from
being well structured, unambiguous, explicit and timely. This is supported by a common understanding of the
purpose, the processes, the actors involved and the information needed.
This document focuses on the foundations for and execution of digital communication in accordance with the
processes and information requirements of a use case. With a focus on communication, this document offers
a natural complement to standards that focus on information management such as the ISO 19650 series,
information containers such as the ISO 21597 series and information modelling such as ISO 16739-1 and
ISO 10303-239.
This document describes how to use various components of an IDM for verifiable and traceable execution of
digital communication. The resulting interaction framework enables standardization of digital communication
in construction processes within any collaboration within and between organizations. As digital
communication spans the entire life cycle of assets and occurs in projects of all sizes and complexities, a
standardized IT approach can benefit a wide range of stakeholders. Support for this standard in various ICT
solutions means that various information management systems are connected. By doing so, it provides a basis
for reliable information exchange and sharing for users, so that they can be confident that the information
they send or receive is accurate and sufficient for the coordination activities they need to perform. This
provides a basis for using common data environment (CDE) solutions and workflows.

Part 2:
Interaction framework
1 Scope
This document specifies a methodology for describing and managing interactions and a format for digital
communication between actors in any use case associated with the management of an asset during all life cycle
stages.
It provides:
— — a methodology that describes an interaction framework for a use case;
— — an appropriate way to map responsibilities and interactions that provides a process context for
information flow;
— — a format in which the interaction framework is specified and executed.
This document is intended to promote secure, verifiable, traceable and high-quality digital IDM
communication between actors during all phases of the life cycle of assets, facilitate interoperability between
software applications used, and to provide a basis for data- and process-driven information exchange and
traceability of communication.
