CEN/TR 17920:2023 (E)
Introduction
CEN/TC 442 is the European technical committee for standardization in the field of structured
semantic life cycle information for the built environment. CEN/TC 442 has published numerous
European standards for BIM in recent years, and many others are in development. Most of this
standardization effort has been in collaboration with international organizations, especially ISO/TC
59/SC 13, the international standardization committee for organization and digitization of
information about buildings and civil engineering works, including building information modelling
(BIM).There is a perception that the information requirements of stakeholders in the infrastructure (3.1)
domain are not as well served by European and international standards as the requirements of those
in the buildings domain. CEN/TC 442 Working Group 6 (WG 6), Infrastructure, was established to
identify stakeholders in the infrastructure (3.1) domain, ascertain their needs in relation to
standardization for BIM, review if those needs are met by current and forthcoming standards, and,
accordingly, make recommendations for the development or revision of standards.This document presents the findings and recommendations of CEN/TC 442/WG 6. The report is
intended to inform future work of CEN/TC 442. In its current work-in-progress state, this report is
also intended to support consultation by WG 6 with other working groups within CEN/TC 442 on the
basis that those working groups are more familiar with the standards for which they are responsible
and the associated standardization efforts.The process for identification of relevant stakeholder groupings and the results of engagement with
selected stakeholders are presented in Clause 4. Engagement included discussions with stakeholders
at a national level and survey of stakeholders across Europe. Selected current initiatives for
standardization of BIM for infrastructure (3.1) are discussed in Clause 5. Clauses 6 through 13 are
structured to correspond to EN ISO 19650-1:2018, Clauses 5 through 12. Based on the analyses
conducted by Working Group 6, each clause discusses the characteristics of BIM for infrastructure
(3.1) relative to those of BIM for buildings, in the context of the relevant standards. The key question
asked in each case is if the standards suitably meet the needs of infrastructure. Key findings are then
presented in each case.The findings are summarized in Clause 14 and recommendations are provided in Clause 15. In
addition to looking broadly across the range of BIM standards, Working Group 6 investigated some
detailed use cases to enable contextualisation of analyses within real-life industry practice. Annex A
presents details of selected case studies analysed. Annex B provides the questions fromt the industry
survey.As of August 2022, Working Group 6 is in the processes of final editing and refinement of this report.
This should be borne in mind by those reviewing this work-in-progress report issued for the purpose
of internal CEN/TC 442 consideration.---------------------- Page: 8 ----------------------

4 Stakeholder engagement
4.1 Stakeholder analysis
The scope of work for this document included identifying key stakeholders and investigating existing
activities. At the outset, a list of typical stakeholder types was identified, broadly grouped under
organization types and professions. The stakeholder types were classified under two criteria with
regard to international standardization of BIM for infrastructure (3.1) in Europe:
— Their power to influence adoption of standards.— Their interest in the adoption of standards.
Refer to Figure 1 for a matrix of the analysis results. This represents a typical condition rather than
that in any one country. Selected stakeholders were omitted or grouped for ease of presentation. Key
stakeholders for engagement during the development of this document were identified as those with
high power and high interest.---------------------- Page: 10 ----------------------

4.2 Stakeholder consultations
4.2.1 General
Based on the results of the stakeholder analysis, stakeholders were engaged as discussed below. This
engagement was either direct as part of this study or indirect as part of the authors’ activities with
national standards organizations, industry bodies, research or professional work. The engagement
considered the stakeholders’ perspectives on the need for standardization related to the
implementation of BIM for infrastructure (3.1) in Europe, and whether or not current European
standards address that need.---------------------- Page: 11 ----------------------

4.2.2 Infrastructure asset owners
With reference to the clause on national transport authorities, the focal point of this part looks into
different type of asset owners as road, rail, airports, waterways etc. Multiple asset owners from every
country are managing their assets to the best of their ability but may be limiting active sharing of
their management methods and structures, with the potential to benefit other asset owners of the
same category. Figure 2 shows collaboration between infrastructure owners.Infrastructure asset owners and operators are largely the same; the owners take over from the
contractor after a new construction is done or when an ongoing operation task is done, by way of
renovated/replaced assets, whereas the operators assume the responsibility for the on-going
maintenance. Owners of infrastructure (3.1), being either state owned or privately owned (private
networks, railways located on industrial production sites, etc.), usually focus on the return on
investment (profit/service achieved) (ISO/TR 21245). Power supply companies are themselves
infrastructure asset owners, e.g. owning their pipelines as well as network supply companies are
owning their cables, where others telecom suppliers are renting to the infrastructure (3.1). Usually,
infrastructure (3.1) as road, rail, runways are owned and maintained by the owners (national
government authorities or agencies), while transport modes as(train/vehicle/heating/water/network) running on rail-tracks/roads/pipes, will be owned by
private people or companies.Figure 2 — Collaboration across infrastructure owners
In the life cycle of assets, we again look to the following succession of life cycle stages (Figure 4, 7.2)
belonging to the infrastructure (3.1) asset owners: stage 1 is planning and, after construction in
stage 4, when the asset owner takes over, they act in stage 5, which is handover. Stage 6, which is
operation, and stage 7, which is demolition. The delivery period of an infrastructure (3.1) project is
often extended and can have several starts and stops in the process, due to environmental, public
involvement, political or economic reasons. As such, stage 2-4 can span several years, which is why
the delivery of project data needs to be predictable, well-structured and can be applied to the
handover and operations in a systematic way.Asset ownership demands can be enforced from the very beginning of an early design phase and
requires satisfactory deliverables in each subsequent stage. EN ISO 19650-3 [3] emphasizes the
importance of setting up a clear information standard as well as information production methods
---------------------- Page: 12 ----------------------SIST-TP CEN/TR 17920:2023
CEN/TR 17920:2023 (E)
and procedures. This entails the structuring and classification (3.3) of information between asset
owners, to ensure that information is useful in a handover to any future operational phase delivery.
A progressive delivery of information needs to satisfy, at any all stage, the infrastructure (3.1) asset
owner. They need to be eligible to look back through the asset information, e.g. to analyse the purpose
of the asset, executed pre-scheduled maintenance and activities as well as reasons for any
unscheduled maintenance activities, in the prior life of the asset. It is very important in the delivery
phase, that information not only describes the finished and delivered construction, but also provides
critical information for owners to maintain their assets.Industry collaboration
Infrastructure asset owners need a common toolbox that helps them align with each of their projects,
allowing for easier collaboration with fewer misunderstandings. The required toolbox could include
specialized software, Common data environments or organizational structures that lend themselves
to integrated, knowledge-sharing practices in asset management, to incentivize new collaboration
between asset owners, in the exchange of methods and processes for common, continuous
improvement.Collaboration across infrastructure asset owners could lead to multiple benefits by sharing
integration and co-working solutions, or the appropriate way to apply the softwares they use to
manage their project to execute a work order. One obvious development could be to engage in cross-
organizational pilot projects with multiple asset owners, where they each provide input by sharing
experiences. The diagram shown in Figure 2 above is a proposed workflow, potentially ensuring the
collaboration of asset management ownership e.g. between national authorities/infrastructure
owners and private companies (client/contractors), to benefit from each other’s data.
On the basis of this process, retrieving classified object data according to the needs of other asset
owners to compare work differences would be a valuable enhancement, e.g. by having an object
library to benefit both asset owners, knowing the object by the same name, settling for a common
syntax and name attribution. Infrastructure assets are not necessarily physical construction objects,
but it can be virtual and that information, in and of itself, should be treated as an asset too. It can be
represented by a part of or a collection or a derivative of physical components.When looking at infrastructure asset owners who have their individual asset systems without
collaboration, the individual initiatives can be useful on their own, but not across the several projects
that make up national infrastructure. For this reason it is useful to make a common classification
(3.3) library which indicates similar or equal classification (3.3) codes across projects. Infrastructure
asset owners can benefit from using classification (3.3) to have control of information models,
tender/bidding material, asset information mode...
