Digital twin standard published by BSI

The new standard builds upon ISO 30173. BS EN 18162:2026 defines the concepts and definitions and is the first part of a set of standards to define the framework for digital twins in the built environment.

According to the BSI, it includes the terms and definitions, the relation to BIM and addresses the lack of standards for the qualitative specification of a digital twin, which can include geometric, attributive, structural and infrastructural quality, as applicable.

The standard’s introduction reinforces the definition of a digital twin: “A digital twin represents a virtual system that contains all relevant information about the target entity for the [twin]’s specific uses, and is not a static representation due to its synchronisation with its target entity over time.”

In a brief LinkedIn post announcing the standard’s publication, BSI built environment sector lead Dan Rossiter FCIAT wrote: “The most interesting bit may be the taxonomy section and how different types of digital twin can relate to the built environment sector.”
