Building information modelling (BIM) - Semantic modelling and linking (SML) - Part 2: Domain-specific modelling patterns
SIST EN 17632-2:2025

This document (part 2) provides extended standard semantic modelling patterns for (at least) the following domain-specific asset aspects:
-   support for distinction between two subtypes of physical objects: spatial regions and real ("tangible") objects; the latter being discrete or continuous ("bulk matter");
-   support for the materialization of physical objects, adding generic chemistry aspects directly relevant for the built environment dealing with materials like concrete, steel, wood and asphalt;
-   support for the interaction between objects including connections, interfaces and ports. Interactions being defined as activities where material, information, energy or forces are transferred;
-   support for the definition of unstructured, human-interpretable, requirements, coming from appointing party needs, laws and regulations or sector recommendations;
-   support for implicit groups having no explicit members (to model situations like "all main girders of some steel bridge");
-   support for the explicit modelling of measurements reusing the existing W3C SOSA ontology (as a lightweight but self-contained SSN core ontology);
-   support for spatial geometry (location/shape) reusing OGC GeoSPARQL (GML/WKT) and the WGS84_pos ontology (GPS).

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.

Library objects for architecture, engineering, construction and use (ISO 22014:2024)
SIST EN ISO 22014:2024

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.

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.

Building construction - Organization of information about construction works - Part 3: Framework for object-oriented information (ISO 12006-3:2022)
SIST EN ISO 12006-3:2022

This document specifies a language-independent information model which can be used for the development of dictionaries used to store or provide information about construction works. The model is extended by instantiating content, such as further objects and their relationships, allowing the content to serve as an ontology, taxonomy, meronomy, lexicon and thesaurus.
NOTE 1    Lexicons are resources for comprising lexical entries for a given language
NOTE 2    Meronomies are type of hierarchies which deals with part-whole relationships
NOTE 3    Ontologies are formal, explicit specification of a shared conceptualizationIt enables classification systems, information models, object models, data templates and process models to be cross-referenced from within a common framework.
This document provides the description of an API allowing the interconnection of data dictionaries as described in ISO 23386.

Guideline for the implementation of Exchange Information Requirements (EIR) and BIM Execution Plans (BEP) on European level based on EN ISO 19650-1 and -2
SIST-TP CEN/TR 17654:2021

This document deals with the processes involved in the procurement and delivery of information to planning and construction projects, specifically with exchange information requirement (EIR) and BIM execution plan (BEP), considering the administrative processes. This document takes into account international standards and specifications as well as recommended practice.
This document is relevant for all parties involved in the tendering of information deliverables. Including both those that require and those that deliver the information. The required information can be relevant for all processes in the life cycle such as design, construction, operation and maintenance and end-of-life processes. It applies above all to e.g. client, asset owners/operators, architects, engineer, contractors, subcontractors etc.
This document provides methodology to appointing parties on how to require and agree the right amount, quality and level of information needs.
It is also important for appointed parties to be able to assess the quality of existing EIRs and identify possible over-specification or gaps. Based on this, it is possible to estimate and calculate the necessary effort for data creation.
This document operationalizes the tendering and appointment process of information deliverables as specified in EN ISO 19650-2:2018. This document does not cover all clauses of EN ISO 19650-2:2018. Its main goal is to provide template examples and guidance for all activities conditioning specification of requirements and deliverables in the production of exchange information requirements and BIM execution plan. Specifically, it covers the “shall” and “shall consider” requirements in EN ISO 19650-2:2018, 5.2.1 (EIR), 5.3.2 (pre-appointment BEP) and 5.4.1 (confirmed BEP). For specification of Scope and out of scope see Table 1 (see Annex A for which part of EN ISO 19650-2:2018 is supported by templates).
