EN ISO 23387:2025 – Building Information Modelling (BIM) — Data Templates for Objects Used in the Life Cycle of Assets

Building information modelling (BIM) — Data templates for objects used in the life cycle of assets (ISO 23387:2025)

EN ISO 23387:2025 presents an essential step toward a digitalized, machine-interpretable approach to describing construction objects throughout their lifecycle. It establishes the standardized structures and concepts for data templates—predefined formats used to consistently store and exchange alphanumerical information for any building or infrastructure object. The focus is on enabling consistent and efficient digital information exchange between software, practitioners, and stakeholders, making BIM implementation more robust, scalable, and reliable.

The standard aligns with ISO 12006-3 and provides the methodology for creating and managing templates in data dictionaries, as well as guidance for linking templates and classification systems. It specifies a UML-based model for templates and an XML Schema Definition (XSD) for implementation. This approach guarantees that manufacturers, designers, operators, and regulators reference and exchange data that is unambiguous and interoperable. It is especially impactful for:

• Software developers (BIM tools, asset management platforms)
• Construction product manufacturers
• Specifiers, designers, and contractors
• Facility/asset managers and building owners
• Regulators and digital compliance officers

This 2025 edition incorporates notable updates: harmonization with the newest ISO 12006-3 data models and an XSD for machine implementation, supporting automated information workflows across the construction lifecycle.

Key highlights:

• Establishes methodology and structure for creating reusable, standardized data templates
• Improves machine interpretability for precise digital asset management
• Aligns BIM data workflows with global frameworks, promoting interoperability and classification links
