Overview - EN ISO 12006-2:2020 (ISO 12006-2:2015)

EN ISO 12006-2:2020 (ISO 12006-2:2015) defines a framework for classification of built-environment information. It specifies how to structure and relate construction object classes (for example by form or function) and recommends titles for classification tables used across the construction lifecycle. The standard is a framework - it does not supply a complete operational classification system or populated tables; rather, it guides organizations that develop local or national classification systems so that harmonization and information exchange are easier.

Key topics and technical scope

• Classification framework: Principles for developing classification systems for construction information, including recommended table titles and views (e.g., element, function, product).
• Object and process modelling: Definitions and relationships between objects (construction object, system) and processes (construction process).
• Composition and classification: Rules for “type-of” (classification) and “part-of” (systems and sub-systems) relations to support hierarchical structuring.
• Properties and tables: Guidance on use of property tables and other classification tables to support different information needs (specification, cost, maintenance).
• Lifecycle coverage: Applies to briefing, design, documentation, construction, operation and maintenance, and demolition.
• Scope of application: Relevant to building and civil engineering works, associated engineering services and landscaping.
• Normative references and guidance: References ISO 22274 for terminology systems; includes informative annexes with table title examples and classification concepts.

Practical applications and users

EN ISO 12006-2 is intended for organizations that develop, publish or implement classification systems and for stakeholders who need consistent information exchange:

• BIM managers and software vendors - to align classification structures used in Building Information Modelling (BIM) and data exchange.
• Standards bodies and national/multi‑national programs - to develop harmonized classification tables suited to local practice.
• Architects, engineers, contractors, cost consultants and facility managers - to improve interoperability for specification, cost planning, procurement and maintenance.
• Owners and asset managers - to ensure consistent lifecycle information for operations and eventual demolition.

Related standards

• ISO 12006 (overall series) - Part 3: Framework for object‑oriented information (complements Part 2).
• ISO 22274 - Systems to manage terminology, knowledge and content (normative reference cited in the standard).
• Adopted as EN ISO 12006-2:2020 by CEN/TC 442 (BIM).

Using EN ISO 12006-2:2020 helps organizations design classification systems that promote interoperability, facilitate international collaboration, and support robust BIM and lifecycle information management.
