BSI publishes PAS 1958 and digital twin standards

“It is principally aimed at helping those managing asset-related information understand which standards are relevant, putting information first in relation to how it flows and how it is structured.”

PAS 1958 can be downloaded for free.

Those interested in PAS 1958 can register to watch a BSI webinar about it on 24 March.

Meanwhile, the BSI has published BS EN 18162:2026, which sets out the concept and definitions for digital twins applied to the built environment.

The new standard builds on ISO 30173. It 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.”
