Uniclass, the classification for the Construction Industry

What is Uniclass?

Launched in 1997, Uniclass, the classification for the construction industry, is the UK implementation of BS ISO 12006-2, providing a structured approach to classifying the building information by organising information based upon common characteristics.

The recent developments and wide-adoption of BIM to manage information across the project timeline, has meant the need for a unified approach to classification, ensuring that information is universally structured regardless of the author. This lead to a review of Uniclass and the development of Uniclass2.

Uniclass2, NBS and CPIC

In 2012, a group lead by NBS and the Construction Project Information Committee (CPIC), an organization comprising representatives from Royal Institute of British Architects (RIBA), the Royal Institution of Chartered Surveyors (RICS), the Institution of Civil Engineers (ICE), the UK Contractors Group (UKCG), the Chartered Institute of Architectural Technologists (CIAT) and the Chartered Institution of Building Services Engineers (CIBSE), was established to help unify and encourage greater use of the Uniclass system. This resulted in the launch of Uniclass 2 with 16 tables.

Uniclass FAQs

Uniclass and NBS Create

NBS Create is the specification and information system of the future and therefore was developed based on the future classification structure. NBS Create was classified using the Work Results table of Uniclass2.
NBS is also the only specification tool to output into COBie. Many of the tables in a COBie spreadsheet require a classification so that the data can quickly be filtered and compared. For construction projects to UK standards and practice, Uniclass2 offers classification for Construction Entities, Spaces, Systems and Products. Within the COBie-UK-2012 specification the Category field in the tables Facility, Space, System and Type may be populated by the corresponding Uniclass2 code.
