INTRODUCTION
Building information modelling (BIM) is an optimizing design process for the construction and
operation of buildings. The information in the model remains coordinated and consistent
throughout the lifecycle of the project to better optimise its construction schedule and operation
(see Figure 1). BIM is a digital process enabled by a set of software, dictionaries, BIM objects
and data which aims to increase efficiency around the building lifecycle, through the design,
operation, maintenance and destruction phases. BIM was initially mainly used at the design
stage to avoid collisions between the different elements of the construction. However, BIM
offers many other possible use cases to be investigated, such as extracting electrical load
demands, simulating photovoltaic production capacity, and simulating thermal and energy
behaviour of the building, etc.

Figure 1 – BIM and the building lifecycle
The main intended benefits of BIM are:
– increasing design dependability and process transparency;
– improving project communication and project marketing;
– shortening construction periods;
– minimizing risks in execution and reducing construction costs;
– increasing the degree of prefabrication;
– use information for building operation purposes.
Governments worldwide recommend or require the use of digitalised information for public
construction projects, recognizing its value for helping to deliver projects successfully.
BIM is a standardised process by ISO TC 59/SC 13 and includes a 3D representation and an
optimised set of data, which can be enhanced by adding further information, such as technical
features.
BuildingSMART is a global community committed to creating and developing open digital ways
of working for built asset environment. BuildingSMART promotes international consensus
among stakeholders on specific standards to accelerate implementation and uptake and
propose standards to ISO TC 59.
ISO 19650 defines the information management process.
IEC 62683-2-2:2025 © IEC 2025
Other standards such as ISO 16739 and dictionaries such as ISO 12006 specifically address
the exchange format. An overview is shown in Figure 2.

Figure 2 – BIM data standard overview
The main elements of the BIM process are:
– Industry foundation class (IFC – ISO 16739-1)
IFC is a standardized, digital description of the built asset industry. It is an open,
international standard (ISO 16739-1) and promotes vendor-neutral or agnostic, and usable
capabilities across a wide range of hardware devices, software platforms, and interfaces for
many different use cases.
– Information delivery specifications (IDS)
An IDS is a computer interpretable document that defines the exchange requirements of
model-based exchange. It defines how objects, classifications, materials, properties, and
even values should be delivered and exchanged. This is often done based on industry
foundation classes (IFC) and additional classifications, materials and properties (national
agreements or company specific ones; either stored in bSDD or somewhere else). This is
the standard to use to define the level of information needs (CEN term), the exchange
information requirements (ISO 19650 term) or even to exchange product data templates
with some more details.
– Building smart data dictionary (bSDD ISO 12006-3, ISO 23386)
The buildingSMART Data Dictionary (bSDD) is a library of classes, properties, relations and
units. It is an online service that hosts classifications and their properties, allowed values,
units and translations. The bSDD allows linking between all the content inside the database.
It provides a standardized workflow to guarantee data quality and information consistency.
– BIM Collaboration Format (BCF)
The BIM Collaboration Format (BCF) allows different BIM applications to communicate
model-based issues with each other by leveraging IFC data that have been previously
shared among project collaborators. BCF was created for facilitating open communications
and improving IFC-based processes to more readily identify and exchange model-based
issues between BIM software tools, bypassing proprietary formats and workflows.
IEC 62683-2-2:2025 © IEC 2025
– Information delivery manual (IDM, ISO 29481-1)
The built asset industry (including buildings and civil infrastructure) is characterized by
bringing many different companies and authorities together in a project specific
organisation. In order to work efficiently, it is necessary for all participants in the
organisation to know which and when different kinds of information have to be
communicated. The issue is even more important when digital tools are applied, since most
industry tools have a very low threshold of tolerance when it comes to the ability to interpret
digital data. The “building information modelling – Information delivery manual” standard
has been developed by buildingSMART in order to have a methodology to capture and
specify processes and information flow during the lifecycle of a facility.
Up to now, electrical engineering has not been adequately represented in BIM (IFC, IDS, BSDD)
although electrical engineering is an essential trade within every property.
Particularly in electrical systems engineering, the expectation is to cover from planning,
execution, operation, to demolition and improve ease of exchange and interoperability between,
different phases, electrical personas and CAD and CAE software.
BIM is the right approach as a working method in the electrotechnical trade of a building (low
voltage and medium voltage). But objects of electrical assemblies should be further detailed
and standardised.
BIM design software should be supplied with objects. The properties of these objects, for
example, the functional description of an electrical distribution panel, will be easier to be
handled by a building designer if this description is based on a common ontology defined by
recognised electrical standards.
This part of IEC 62683-2 series is intended to be used in combination with the following part:
– IEC 62683-1, Catalogue data
The described data models including in this part is intended to be hosted within IEC CDD in the
class tree dedicated to engineering data of low-voltage switchgear, controlgear and their
assemblies. This branch of the IEC 62683 DB dictionary is intended to be used by catalogue
consortia, other database standards and engineering software editors as reference to low-
voltage switchgear and controlgear standards.
IEC CDD ontology data model followings IEC 61360-2 and ISO 13584-42. It includes the unique
identification of each dictionary and dictionary element according to ISO 29002-5 called
"international registration data identifier" (IRDI). This identifier includes the IEC International
Code Designator (ICD) “0112” registered according to the registration authority identification
concept as defined in ISO/IEC 6523-1.
