Building information modelling (BIM) - Data templates for construction objects used in the life cycle of built assets - Concepts and principles (ISO 23387:2020)

This document sets out the principles and structure for data templates for construction objects. It is developed to support digital processes using machine-readable formats using a standard data structure to exchange information about any type of construction object, e.g. product, system, assembly, space, building etc., used in the inception, brief, design, production, operation and demolition of facilities.
This document provides the specification of a taxonomy model that defines concepts from ISO 12006-3:2007, i.e. objects, collections and relationships between them, to support the information need for the specific purpose of the data template.
This document provides an EXPRESS specification with extensions of the EXPRESS-G notation and specification from ISO 12006-3:2007. These extensions have been provided to support market needs developed since the publication of ISO 12006-3 in 2007.
This document provides the rules for linking between data templates and IFC classes within a data dictionary based on ISO 12006-3:2007.
This document provides the rules for linking between data templates and classification systems within a data dictionary based on ISO 12006-3:2007.
The target audience of this document is software developers and not construction industry domain experts appointed to create data templates based on sources describing information needs.
It is not in the scope of this document to provide the content of any data templates. The data structure provided is intended to be used for developing specific data templates based on standards developed in ISO/IEC, CEN/CENELEC, national standardization organizations, or other sources describing information needs.

Bauwerksinformationsmodellierung (BIM) - Datenvorlagen für Bauobjekte während des Lebenszyklus eines baulichen Vermögensgegenstandes - Konzepte und Grundsätze (ISO 23387:2020)

Dieses Dokument legt die Grundlagen und die Struktur für Datenvorlagen für Bauobjekte dar. Es unterstützt digitale Prozesse durch die Verwendung maschinenlesbarer Formate auf der Grundlage einer genormten Datenstruktur zum Austausch von Informationen zu jeder Art von Bauobjekten, z. B. Produkt, System, Baugruppe, Raum, Gebäude usw., während anfänglichem Entwurf, Beauftragung, Konstruktion, Bau, Betrieb und Rückbau.
Dieses Dokument enthält die Spezifikation einer Taxonomie, die Konzepte aus ISO 12006 3:2007, d. h. Objekte, Sammlungen und deren Beziehungen zueinander definiert, um den Informationsbedarf für den speziellen Zweck der Datenvorlage zu unterstützen.
Dieses Dokument enthält eine EXPRESS Spezifikation mit Erweiterungen der EXPRESS G Notation und  Spezifikation aus ISO 12006 3:2007. Diese Erweiterungen wurden zur Unterstützung der Marktanforderungen bereitgestellt, die sich seit Veröffentlichung von ISO 12006 3 im Jahr 2007 entwickelt haben.
Dieses Dokument stellt Regeln für die Verknüpfung zwischen Datenvorlagen und IFC Klassen innerhalb eines auf ISO 12006 3:2007 basierenden Datenkatalogs auf.
Dieses Dokument stellt Regeln für die Verknüpfung zwischen Datenvorlagen und Klassifikationssystemen innerhalb eines auf ISO 12006 3:2007 basierenden Datenkatalogs auf.
Die Zielgruppe dieses Dokuments sind Softwareentwickler und nicht Experten für den Bereich der Bauindustrie, die ernannt wurden, um Datenvorlagen auf Grundlage von Quellen zu erstellen, die sich mit der Beschreibung von Informationsanforderungen befassen.
Die Bereitstellung des Inhalts von Datenvorlagen liegt außerhalb des Anwendungsbereichs dieses Dokuments. Die vorgestellte Datenstruktur soll für die Entwicklung spezifischer Datenvorlagen verwendet werden, die auf Normen beruhen, die von ISO/IEC, CEN/CENELEC, nationalen Normungsorganisationen oder anderen Quellen, die sich mit der Beschreibung von Informationsanforderungen befassen, erarbeitet wurden.

Modélisation des informations de la construction (BIM) - Modèles de données pour les objets de construction utilisés durant le cycle de vie des biens construits - Concepts et principes (ISO 23387:2020)

Le présent document définit les principes et la structure des modèles de données pour les objets de construction. Il est élaboré afin de prendre en charge les processus numériques utilisant des formats exploitables par ordinateur dotés d'une structure de données normalisée pour échanger des informations sur tout type d'objet de construction, par exemple produit, système, assemblage, espace, bâtiment, etc. utilisé dans le démarrage, le programme, la conception, la production, la mise en service et la démolition des installations.
Le présent document propose la spécification d'un modèle taxonomique qui définit les concepts provenant de l'ISO 12006-3:2007, c'est-à-dire objets, collections et les relations entre eux, afin de prendre en charge le besoin d'information dans l'objectif spécifique du modèle de données.
Le présent document fournit une spécification EXPRESS ainsi que les extensions de la notation EXPRESS‑G et de la spécification de l'ISO 12006-3:2007. Ces extensions sont destinées à prendre en charge les besoins commerciaux apparus depuis la publication de l'ISO 12006-3 en 2007.
Le présent document donne les règles de liaison entre les modèles de données et les classes IFC dans un dictionnaire de données, sur la base de l'ISO 12006-3:2007.
Le présent document donne les règles de liaison entre les modèles de données et les systèmes de classification dans un dictionnaire de données, sur la base de l'ISO 12006-3:2007.
Le public cible du présent document est constitué des développeurs logiciels, et non des experts de l'industrie de la construction en charge de créer des modèles de données sur la base de sources décrivant des besoins d'information.
La fourniture du contenu des modèles de données ne fait pas partie du domaine d'application du présent document. La structure de données proposée doit être utilisée pour développer des modèles de données spécifiques basés sur les normes développées par l'ISO, l'IEC, le CEN/CENELEC, les organismes nationaux de normalisation ou d'autres sources décrivant les besoins d'information.

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.

Introduction
Building information modelling (BIM) provides a digital process for describing and displaying
information required in the planning, design, construction and operation of constructed facilities. This
approach encompasses all aspects of the built environment, including civil infrastructure, utilities and
public space.
ISO 19650 (all parts) sets out the recommended concepts and principles for business processes across
the built environment sector in support of the management and production of information during the
life cycle of built assets when using building information modelling (BIM). To support the management
and production of information in these business processes, standardization is of the highest importance.
Machine-readable data is essential to provide a reliable and sustainable exchange of information in an
asset life cycle process.
Data templates provide a standardized data structure to describe the characteristics of construction
objects, enabling seamless information exchanges of construction industry business semantics through
the life cycle of any built asset.
Data templates should be standardized and made available across the built environment sector through
data dictionaries based on ISO 12006-3:2007.
Data templates should be used in conjunction with Industry Foundation Classes (IFC) in ISO 16739-1 to
enable and sup
