Introduction

Building information modelling (BIM) provides a digital technology for describing and displaying

information required in the planning, design, construction and operation of constructed facilities.

Increasingly this modelling approach is expanding to encompass all aspects of the built environment,

including civil infrastructure, utilities and public space.

EN ISO 19650-1:2018 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, the significance of 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 will enable construction project stakeholders to exchange information about construction

objects used in construction works through an asset life cycle, using the same data structure, terminology,

and globally unique identifiers to enable machine-readability. Data templates will be standardized and made

available across the built environment sector through data dictionaries based on EN ISO 12006-3.

The data template structure in this standard is based on the general data template structure in

prEN ISO 23387.

In Europe, various regulations and directives lay down harmonised rules for the marketing of products and

systems, and the CEN/CENELEC standards provide a common technical language to assess the performance

of products and systems for construction works. The common technical language should be the foundation

when creating a digital terminology for the European construction industry. The digital terminology should

be used in standardized structures, data templates, for describing construction products. The regulatory

nature of the common technical language requires that the digital terminology is compatible and does not

conflict with the regulatory declaration.

Building regulations, together with standards and specifications are intended to ensure that basic

requirements for construction works (Annex I of EU Regulation 305/2011 – Construction Products

Regulation) and other technical performances are met. Basic requirements for construction works and other

technical performances should be made digitally available and used as part of the 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 modeling (BIM).

4 Terminology variation between prEN ISO 23387 and CPR

In prEN ISO 23387, a general data structure has been introduced to define data templates for construction

objects. The terminology used in prEN ISO 23387 is aligned with terminology used in other BIM standards

developed in ISO/TC 59/SC 13 and CEN/TC 442.

The CPR lays down harmonised rules for the marketing of construction products in the EU. The Regulation

provides a common technical language to assess the performance of construction products.

Both terminology approaches differ in some parts. In order to define a specialized template for the area of

CPR, the variation of terminology is explained in Table 1.

The concept names from prEN ISO 23387 are reused in the UML in Figure 1 in this document, and

clarification is provided in Table 1, to make the terminology more understandable for use cases related to

the CPR.

The terminology from prEN ISO 23387 is used throughout this document where description of creation of

concepts is provided. For text related to the content in harmonised technical specifications, CPR related

terminology is used.

Table 1 provides a list with concept names from prEN ISO 23387, together with a clarification which is more

in line with the CPR terminology.

The structure of data templates created according to this document shall follow the concepts and principles

in prEN ISO 23387. The rules given in the UML diagram in Figure 1 are according to the UML diagram in

prEN ISO 23387, whereas in this document a simplified version is provided.

Figure 1 provides a UML diagram with the data structure for data templates that will be created based on

harmonised technical specifications.
Figure 1 — Data template UML diagram

For some concepts, self-relationships are provided. This mechanism allows for relating two concepts of the

same kind to each other. There are several use cases that require self-relationships, as described below in

subclauses 5.2 to 5.4. The following UML diagrams are extracts from Figure 1.
5.2 Data templates for construction products as kits

The self-relationship supports creation of data templates for kits. For this purpose, self-relations are

applicable for construction object concepts, representing construction products, and data template concepts.

UML representations of these relationships are provided in Figures 2 and 3.

5.3 Dependency relationships for properties

Two properties can be connected by a self-relationship. This mechanism supports a value for a single

property to be based on the value of another property. UML representation of this relationship is provided

in Figure 4.
Figure 4 — Property self-relationship
5.4 Grouping properties in groups of properties

For the concept group of properties, a self-relationship is needed for the purpose of nesting properties with

different quantity kinds into the same group of property. UML representation of this relationship is provided

in Figure 5.
