BSI Publishes PAS 1958 and Digital Twin Standards

Key Takeaways

• PAS 1958 maps existing built‑environment data standards.
• Developed from Innovate UK BridgeAI research.
• Guides asset managers on relevant information standards.
• BS EN 18162:2026 defines digital‑twin terminology for construction.
• Links digital twins to BIM and quality specifications.

Summary

The British Standards Institution (BSI) has released two new standards for the built environment. PAS 1958 provides a consolidated framework that maps existing data and information standards, stemming from the government‑backed BridgeAI programme aimed at accelerating AI adoption among SMEs. In parallel, BSI issued BS EN 18162:2026, the first part of a digital‑twin standard series, defining concepts, taxonomy and links to BIM while building on ISO 30173. Both documents are freely available and accompanied by a webinar on 24 March.

Pulse Analysis

The construction industry has long grappled with fragmented data sources, making it difficult to achieve seamless information flow across projects. Standard‑setting bodies like BSI play a pivotal role in harmonising terminology and protocols, which in turn drives efficiency and reduces costly rework. By publishing a unified landscape of existing standards, PAS 1958 addresses a critical gap, offering stakeholders a clear map of how data standards intersect and where they can be applied within asset lifecycles.

PAS 1958 emerges from the BridgeAI programme, a government initiative designed to accelerate artificial‑intelligence adoption among small and medium‑sized enterprises. The standard’s framework helps asset owners and managers quickly identify the most relevant data standards for their operations, prioritising information architecture over siloed datasets. This clarity is expected to boost AI‑enabled analytics, improve predictive maintenance, and foster greater collaboration between contractors, owners, and technology providers, ultimately delivering higher return on investment for digital transformation projects.

Complementing the data‑standard guide, BSI’s BS EN 18162:2026 introduces the first formal definition set for digital twins in the built environment. Building on ISO 30173, the standard establishes a taxonomy that links digital‑twin concepts directly to Building Information Modelling (BIM) processes and outlines quality criteria for geometry, attributes, and structural data. As digital twins become central to smart city initiatives and lifecycle asset management, this standard provides the necessary linguistic and technical foundation for interoperability, paving the way for a broader suite of standards that will further integrate virtual and physical infrastructure.
