Building information modelling - Information structure based on EN ISO 16739 1 to exchange data templates and data sheets for construction objects - Part 1: Data templates and configured construction objects

The digital transformation of the construction industry includes also the digital transformation of the supply change of construction products. With ISO 16739-1 exists an open language to design, transfer and maintain construction models. The construction models (eg. of a building) contain a digital twin of real-life products. The data of these products should be transported in a digital format on the way from the manufacturer to the building owner.
This product data should be expressed also in an easy and open way. The creators of product data files should be able to do this manually or automatically, as they like it. The users of product data should be able to use it to:
• Import products easily in the as-planned-bim-models to plan with the products in an early stage of development
• Import delivered real life products easily in their as-built-bim-models to document them for a later stage of development
These scenarios fit in the business models of manufacturers, planners, construction companies and facility managers.
The working group 4 of CEN-TC442 has published proposals for creating new work items in the sector of CEN regarding the storage and the transport of product data in the sector of building information modelling (BIM):
prEN ISO 23386: Building information modelling and other digital processes used in Construction – Methodology to describe, author and maintain properties in interconnected dictionaries
prEN ISO 23387: Data templates for construction works entities, Part 1:  Objects, collections, and relationships defining the general structure of data templates
This standard defines a format for exchanging empty product data templates and filled product data templates (product data) and therefore fills the missing link between the product data sources (e.g. catalogues) from the manufacturers to the construction models of the designers and owners.
The part 1 of the standard describes a way to represent information templates and configured products in a library based on a structure based on ISO 16739-1 (prEN ISO 16739-1) and how this relates to the upcoming standards prEN ISO 23386 and prEN ISO 23387.
The part 2 will define the way, how a (requirements) request can be formulated with EN ISO 16739 and how this can be used to represent variants of configurable products. The requests by part 2 will be applicable to product libraries based on part 1.
The part 2 will furthermore define a way, to create a constraint based product library for highly configurable products to
support an interactive selection process. The application of an request to a "Part1-Library" and to a "Part2-
Library" shall response same products as the result. It is up to the manufacturers to choose the way, they want to represent their products ("Part1-Library" and/or
"Part2-Library"), they just have to be sure, that all requests can be applied to both types of libraries.

Building Information Modelling (BIM) - Datenstruktur nach EN ISO 16739-1:2018 für den Austausch von Datenvorlagen und Datenblättern für Bauobjekte - Teil 1: Datenvorlagen und konfigurierte Bauobjekte

Dieses Dokument definiert die syntaktischen Merkmale einer generischen Struktur zur Übertragung von Bauobjektdaten entsprechend EN ISO 16739-1:2020, EN ISO 23386 und EN ISO 23387.
Durch die Anwendung dieses Dokuments können Interessenvertreter der Bauindustrie ihre Informationen zu Bauobjekten (z. B. Produktdaten) anhand eines maschinell interpretierbaren Formats strukturieren, steuern, aktualisieren, verwalten und übertragen.
Darüber hinaus können mehrere Interessenvertreter des Prozesses ihre Softwaretechnologien bestmöglich nutzen, wobei sie Datenduplizierung vermeiden, Zeit sparen sowie Qualität und Transparenz verbessern. Das Szenario, in dem diese Norm gilt, betrifft Hersteller, Konstrukteure, Ingenieure sowie Anlagen- und Gebäudeverwalter.
Der syntaktische Ansatz betrachtet die Möglichkeit der Wiederverwendung von Spezifikationen entsprechend der internationalen Norm EN ISO 16739-1:2020 als primäres Ziel. Dieses spezifische Ziel wird durch die Lieferung der Modell-Bereichs-Definition (MVD) „Datenansicht von Bauobjekten“ (COD) erreicht, die neben den anderen bereits veröffentlichten MVD zur Verfügung gestellt wird.
Entwickler von Softwarehäusern und Softwareanwendungen können dieses Dokument dazu nutzen, Schnittstellen zum Importieren und Exportieren von Bauobjektdaten entsprechend der offiziellen Norm EN ISO 16739-1:2020 zu implementieren.

Modélisation des informations de la construction (BIM) - Structure des informations basée sur l'EN ISO 16739-1:2018 pour l'échange de modèles de données et de feuilles de données pour les objets de construction - Partie 1: Modèles de données et objets de construction configurés

Le présent document définit les caractéristiques syntaxiques d’une structure générique pour le transport de données relatives aux objets de construction s'appuyant sur les normes EN ISO 16739-1:2020, EN ISO 23386 et EN ISO 23387.
L'application de ce document permet aux parties prenantes du secteur de la construction de structurer, encadrer, mettre à jour, maintenir et transporter leurs informations sur les objets de construction (par exemple les données de produits) dans un format interprétable par les ordinateurs.
En outre, plusieurs intervenants dans le processus peuvent tirer le meilleur parti de leurs technologies logicielles, en évitant la réplication des données, en gagnant du temps et en améliorant à la fois la qualité et la transparence. Les principaux acteurs concernés par l’application de la présente norme sont les producteurs, les concepteurs, les constructeurs, les gestionnaires d'actifs et les exploitants.
L'approche syntaxique considère comme principal objectif la possibilité de réutiliser les spécifications données dans la Norme internationale EN ISO 16739-1:2020. Cet objectif spécifique est atteint grâce à la définition de vue de modèle (MVD Model View Definition) « Construction Objects Data View - vue de données d’objets de construction » (COD) qui est disponible avec les autres MVD déjà établies.
Les éditeurs de logiciels et les développeurs d'applications logicielles peuvent utiliser ce document pour implémenter des interfaces pour l'importation et l'exportation d'objets de construction conformément à la norme officielle EN ISO 16739-1:2020.

Overview

prEN 17549-1 (CEN) defines an information structure for exchanging product data templates and configured construction objects in Building Information Modelling (BIM). Based on EN ISO 16739-1 (IFC), the standard specifies a format to transport both empty data templates and filled product data (data sheets) from manufacturers through designers and contractors to owners and facility managers. It fills the interoperability gap between product catalogs and BIM models so products can be imported into as‑planned and as‑built models in a consistent, machine‑readable way.

Key topics and technical requirements

• Data templates and configured objects: Defines how to represent empty templates and fully configured construction objects in a reusable library structure based on ISO 16739-1.
• Product data exchange format: Standardizes a digital format for transporting product data (catalogues, data sheets) allowing manual or automated creation and consumption.
• Core schemas and IFC alignment: References core IFC schemas (IfcKernel, IfcProductExtension, shared element schemas) and related entity/property/quantity sets as the structural foundation.
• Declarations and associations: Covers declarations for templates, objects and classifications, plus document and classification associations to maintain provenance and semantic context.
• Units, measures and project context: Explicitly handles units, measures and project-level document information to ensure consistent interpretation across tools.
• Library models for configurable products: Part 1 defines the library format; Part 2 will define request/requirement formulations and constraint‑based configurable product libraries so interactive selection yields consistent results across Part1 and Part2 libraries.
• Transport and software identity: Includes concepts for transport packaging and software identity to support cross‑platform interoperability.

Practical applications and users

Who benefits:

• Manufacturers: publish standardized product templates and configured product data for catalogs and digital product declarations.
• Architects & planners: import product templates into as‑planned BIM early in design for accurate specification and coordination.
• Contractors & logistics: use data sheets for procurement, on‑site delivery tracking and construction site management.
• Facility managers / owners: capture as‑built product data for operations, maintenance and asset management.
• Software vendors & online platforms: implement import/export, libraries and search functions based on the standard to enable seamless data exchange.

Practical uses:

• Automated import of manufacturer product data into BIM models
• Consistent as‑built documentation for handover and FM
• Configurable product selection workflows and catalogue interoperability
• Enabling digital procurement and supply‑chain integration in construction

European foreword
This document (prEN 17549-1:2022) has been prepared by Technical Committee CEN/TC 442
“Building Information Modelling (BIM)”, the secretariat of which is held by SN.
This document is currently submitted to the CEN Enquiry.
Building Information Modelling (BIM) can be used as a method to plan build and operate buildings in a
digital and collaborative way. One core aspect of BIM is the possibility to store information about
buildings in a consistent and comprehensive digital model. The standard EN ISO 16739-1:2018 defines
an open and vendor neutral structure for these building models. The application of this standard enables
all stakeholder in the construction industry to exchange the models, or to exchange parts of the models,
based on their use cases. The present standard defines a subset of EN ISO 16739-1:2018, that can be used
to describe, store and exchange single construction objects or a set of construction objects, e.g.
construction products or other model elements. The entirety of the objects together, then again results
in the model of the building.
The standard is applicable in the phases of planning, building and operating of buildings. The standard
defines related aspects, especially how to
• store and exchange data templates for construction objects based on prEN ISO 23386 and
prEN ISO 23387
• store and exchange data sheets that include the specify information for construction objects
The seamless compatibility to EN ISO 16739-1:2018 enables the users of this standard to assembly the
information about construction objects in the model of the building.
Any feedback and questions on this document should be directed to the users’ national standards body.
A complete listing of these bodies can be found on the CEN website.
Introduction
The digital transformation of the construction industry fully interests the production chain of
construction involving related activities as manufacturing, certification, promotion, marketing,
procurement, selection, supply, transportation, transformation, assembly, installation, maintenance and
replacement over the time. Effective digital dialogues between these activities overcomes the current
exchange traditionally based on documentation, no matter if printed or digital, which for the most cases
is not digitally interpretable.
The supply chain of construction needs a complete digitalization of information transactions sharing data
and construction objects characteristics. The digital supply chain shall comply to the standards used in
the design, construction and maintenance stages.
The smart transport of construction objects data needs a clear and common understanding of the format
to express the structure and the data. The data can be transported in several ways, e.g. via direct database
connect, or via webservices or file transfer. In all cases, the sender and the receiver of the digital data
need a standard to implement import and export of data.
This standard defines the format for the exchange of construction objects data, based on the
EN ISO 16739-1:2018 and contains of two parts. The Part 1 defines formats for the exchange of data
templates, catalogues of configured construction objects and construction data. The Part 1 includes basic
structures, that are reusable also by Part 2 (shared elements). The Part 2 includes the structures that are
used to express requirement requests and responses as declarative expressions.
The following not exhaustive list of purposes is identified in the context of digital construction object data
exchange:
Detailed digital description of a construction object
In order to identify and understand the function of a construction object, a technical description is
needed. This standard allows the exchange of descriptions, technical and business properties, geometry,
information like pictures and mounting instructions in a digital data structure. This digital object
description is used for design, specification, quotation processes that converge toward Asset Information
Models.
Procurement and purchase
The digital description of construction objects, based on properties with standardized structures, makes
searches in catalogues easier and automatable. It grants the possibility to query construction object
properties across digital marketplace. The purchase of products is more reliable if features and
performances are digitally available.
