Data structures for electronic product catalogues for building services - Part 5: Product catalogue exchange format (ISO/DIS 16757-5:2024)

Data structures for electronic product catalogues for building services - Part 5: Product catalogue exchange format (ISO/DIS 16757-5:2024)

The focus of ISO 16757 is the support of manufacturers to provide their product data in electronic product catalogues.
This part of the standard – ISO 16757 Part 5: Product catalogue exchange format - describes how product catalogue data is exchanged as IFC format according to ISO 16739-1 from manufacturers to designers of building services systems.
With ISO 16739-1 (IFC), an open language exists for the creation, transfer and maintenance of design models.
prEN 17549-1 and prEN 17549-2 define the data exchange of scalable product properties within IFC. These standards provide a Model View Definition (MVD), a subset of ISO 16739-1 from an information technology perspective. It focuses on core classes and relies on external data dictionaries to describe business semantics.
This document completes the description of the IFC-based data exchange format for manufacturer catalogues by describing how to model:
•   Catalogue metadata
•   Product classes
•   Constraints for parametric data
•   Product accessory structures
•   Constraints for assembling composable products and accessories
•   Reusable and multiply used data blocks
•   Product properties as defined in the related library  
•   Static product properties
•   Dynamic computable properties
•   Geometric data of product spaces
•   Geometric data of product symbols
•   Geometric data of product shape
•   Geometric data of product ports
•   Article numbers
•   Etc.
This document focuses only on the format of the data exchanged and not on how to process it.
This document is aimed at both software manufacturers for the construction sector and professionals in the sector who use their software.

CEN/TR 18093:2024(Main)
Framework and Implementation of Common Data Environment solutions and workflow, in accordance with EN ISO 19650
SIST-TP CEN/TR 18093:2024

This New Work Item will extend the basic information given in the EN ISO19650 and in the "Guidance to EN ISO 19650". It will detail and structure the concept of a Common Data Environment (CDE) as a workflow for the collaborative process of managing the information and information containers as solutions that fit to the management and project processes inherent for BIM
It may be necessary to introduce further concept details as elements for understanding and implementation. Archiving and versioning of information containers can become very complex when considering various typical information situations of a project.
Further elements, rules and terminology for information management and digitisation may need to be explained and technically framed in the context of a CDE. It will be a large advantage developing at the same time the "Open API for CDE" in TC442 WG2
In particular this Work Item will describe
- how to link a CDE according to EN ISO 19650 to an already existing Asset Management Systems of the Asset Owner.
- how to maintain and manage "living documents" like Information Models (AIM, PIM)
- how to maintain, exchange and manage Information Requirements like (OIR, AIR, EIR) as well as BIM Execution Plans (BEP)
- how to use and implement Information Delivery Plans for the above entities (MIDP and TIDP in ISO 19650)
- how to manage and collaborate between various Information Containers like models, requirements, container states
- how to support Process Workflow by a CDE based on the IDM concept
It will simply have to describe how to provide "Common Data Environment" throughout the whole life cycle (horizontal aspect) and throughout the spectrum of management levels and stakeholders (vertical aspect).
In the work item proposed here, all important terms, processes and targets are to be expanded around the CDE concept. Relations to already existing normatives will be given.
Informative attachments such as templates and examples could be provided to the benefit of planner, supplier and operator as further guidelines.

This document specifies requirements for defining structure and content for library objects to support project inception, brief, design, tendering, construction, operations, use and demolition, supporting the development of information throughout the process, in connection with building information modelling (BIM) and the organization of the objects into libraries.
This document does the following:
Establishes requirements for defining template objects, generic objects and product objects in data-driven library and design processes.
Establishes requirements for graphical symbols and other graphic conventions for use on drawings for the built environment, giving principles and definitions for the symbolic and simplified visual presentation of objects. It also describes a rationale of symbolism which establishes rules for the design of graphical symbols and other graphic conventions and gives recommendations for the application of those rules and the ways in which symbolism should be used.
Defines the purposes of characterizing the shape and measurement of library objects.
Defines the purposes of specifying and assessing properties for library objects. It defines the information appropriate for specific uses, including specification of the desired outcome (typically by designers and engineers) and the selection of identified products (typically by contractors and subcontractors). It also gives recommendations for the application of assemblies in integrated BIM working.
Refers to the Industry Foundation Classes (IFC) schema as a common object model.
This document is applicable to all professionals and service providers who produce and use library objects with generic and product-specific information. This group includes, but is not limited to, product manufacturers and suppliers, library authors, designers and engineers, contractors, owners, maintainers and commissioners.

Industry Foundation Classes (IFC) for data sharing in the construction and facility management industries - Part 1: Data schema (ISO 16739-1:2024)
SIST EN ISO 16739-1:2024

This document represents an open international standard for information used in Building Information Modeling (BIM) that is exchanged and shared among software applications used by the various participants in the construction or facility management industry sector. This document includes definitions that cover information required for buildings and infrastructure works over their life cycle. This edition of the document added coverage of information required for infrastructure facilities including bridges, roads, railways, waterways and port facilities.
This document comprises the publication of a data schema, its documentation, the property and quantity set definitions and the mechanism of an exchange file format structure.
Definitions from this document are used to support different recognized work flows in the construction and facility management industry sector, representing information deliveries. Such information deliveries can be described according to ISO 29481.
Different implementation levels of this document can be defined to better support multiple information deliveries, they are referred to as a Model View Definition (MVD). Each MVD identifies which subset of the definitions of this document imposes requirements for implementation in software applications. Conforming software applications need to identify the model view definition they conform to when applying for software certification.
The following are within the scope of this edition of this document:
BIM exchange format definitions that are required during the life cycle phases of buildings and infrastructure:
demonstrating the need;
conception of need;
outline feasibility;

Building information modelling - Information structure based on EN ISO 16739 1 to exchange data templates and data sheets for construction objects - Part 2: Configurable construction objects and requirements
SIST EN 17549-2:2023

The digital transformation of the construction industry includes also the digital transformation of the supply chaine of construction products. With EN ISO 16739-1 exists an open language to design, transfer and maintain construction models. The construction models (e.g. 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 factory 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:
•   Express their requirements related to products
•   Describe configurable products
•   Import product data easily in the BIM models at any stage of the project (design, construction, operation)
•   Export product data easily from the BIM models at any stage of the project (design, construction, operation)
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):
EN ISO 16739-1:2018: Industry Foundation Classes (IFC) for data sharing in the construction and facility management industries- Part 1: Data schema
EN ISO 12006-3: Building construction – Organization of information about construction works – Part 3: Framework for object-oriented information
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 to negotiate product data templates, express requirements and describe configurable products and therefore fills the missing link between the product data sources (e.g. catalogs) from the manufacturers and the BIM models of the designers, builders, and owners.

BIM in infrastructure - Standardization need and recommendations
SIST-TP CEN/TR 17920:2023

The scope of this document is as per the scope of CEN/TC 442/WG 6, that is:
-   Identify key stakeholders.
-   Investigate existing activities within standardization for BIM in infrastructure (3.1).
-   Formulate the need for standardization related to the implementation of BIM for infrastructure (3.1) in Europe, not covered by existing standards and ongoing standards development.
-   Make recommendation on whether standards are to be developed and if so, how this can be done.
For the purpose of this document, the term 'BIM standards' is a loose reference to standards available for the use of BIM, including those under the responsibility of CEN/TC 442, ISO/TC 211 and ISO/TC 59. It is not a defined term.

EN 17632-1:2022(Main)
Building information modelling (BIM) - Semantic modelling and linking (SML) - Part 1: Generic modelling patterns
SIST EN 17632-1:2023

This document addresses syntactic and semantic interoperability for information describing assets going through their life cycle in the built environment. It assumes the underlying technical interoperability provided already by the Internet/World Wide Web (WWW) technology-stack. The syntactic aspects relate to the Linked Data (LD)/Semantic Web (SW) formats and the SPARQL direct access method provided. The semantic aspects relate to the LD/SW-based information models in the form of thesauri and ontologies giving meaning to the information.
The following information architecture (Figure 1) applies.
This document specifies:
- a conceptual "L1: Information language" with four RDF-based language bindings being SKOS, RDFS, OWL and SHACL, including:
- a choice of 'linked data'/RDF-based formats (to be used for all modelling and language levels); and
- a generic Top Level Information Model of a total "M1: Information model", here "an upper ontology", including:
- a set of generic information modelling patterns for identification, annotation, enumeration datatypes, complex quality/quantity modelling, decomposition and grouping.
This modelling approach for information models and information sets is relevant within the built environment from multiple perspectives such as:
- Building information modelling (BIM);
- Geographical information systems (GIS);
- Systems engineering (SE);
- Monitoring & control (M&C); and
- Electronic document management (EDM).
Annex E discusses in an informative way how the information models and sets relevant for these different worlds can be linked together using LD/SW technology.
This document does not specify a full meta-'information model', sometimes referred to as a 'Knowledge Model (KM)'. EN ISO 12006-3 provides such an often used model for the built environment. In Annex D, Subclause D.3 it is shown how this existing model can be made compliant to this document. The only direct support for this meta level comes in the form of the possibility to define 'types' (enumeration types or concept types) and 'objectifications' as metaconcepts.
This document does not specify a meta-'information language' since this is already provided by the concrete RDF-based language bindings (being RDFS).
The scope of this document in general excludes the following:
- Business process modelling;
- Software implementation aspects;
- Information packaging and transportation/transaction aspects already handled by ISO TC59/SC13 Information container for linked document delivery (ICDD) ([13]) respectively various information delivery manual (IDM) / information exchange requirements (EIR)-related initiatives; and
- Domain-specific (here: 'built environment'-specific) content modelling in the form of concepts, attributes and relations at end-user level (the actual ontologies themselves) beyond a generic top level information model ('upper ontology') and modelling and linking patterns.

Organization and digitization of information about buildings and civil engineering works, including building information modelling (BIM) - Information management using building information modelling - Part 4: Information exchange (ISO 19650-4:2022)
SIST EN ISO 19650-4:2023

This document specifies the detailed process and criteria for decision makings when executing an information exchange as specified by the ISO 19650 series to ensure the quality of the resulting project information model or asset information model. It details the implementation of the concepts in ISO 19650-1 and is applicable to any information exchange within the delivery stages covered by ISO 19650-2 and operational trigger events covered by ISO 19650-3.
This document is applicable to assets of all sizes and all levels of complexity. This includes portfolios of buildings, campuses, infrastructure networks, individual buildings and pieces of infrastructure. The requirements in this document should be applied in a way that is appropriate to the scale and complexity of the asset. This document makes use of the phrase “shall consider”. This phrase is used to introduce a list of items that the person in question is required to think about carefully in connection with the primary requirement described in the subclause. The amount of thought involved, the time taken to complete it, and the need for supporting evidence depend on the complexity of the asset, the experience of the person(s) involved, and the requirements of any national policy on introducing building information modelling. On a relatively small or straightforward asset, it can be possible to complete, or dismiss as not relevant, some of these “shall consider” items very quickly. One way to help identify which of the “shall consider” statements are relevant can be to review each statement and create templates for assets of different sizes and complexity.
