Building information models - Information delivery manual - Part 2: Interaction framework (ISO/DIS 29481-2:2024)

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 (ISO/DIS 29481-2:2024)

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.

Foreword
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.
The procedures used to develop this document and those intended for its further maintenance are 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. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
