Uniclass, the classification for the Construction Industry

IMPORTANT: For the latest information on classification, please read about the new Uniclass 2015 launched as part of the NBS BIM Toolkit in April 2015.

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 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 led 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.

Early in 2014, CPIC gave the rights to Uniclass2 to the UK government, in the form of the Technology Strategy Board.

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.

Technology Strategy Board ‘free-to-use Digital BIM Toolkit’ Development Project

This project, which is being run in partnership with the BIM Task Group and Department for Business, Innovation & Skills (BIS), involves the development of a free-to-use digital BIM tool that can capture, validate and store information – this will help to complete Level 2 BIM requirements.

A number of teams are taking part to win funding for the further development of the project which includes reviewing Uniclass 2.

A team led by NBS in one of a number of teams that has won a funding award from the Technology Strategy Board for a first stage feasibility study into the development of a digital BIM tool. Submission of phase proposals are due in July 2014.

ISO 12006-2

Uniclass is the UK implementation of ISO 12006-2, the international framework standard for construction sector classification. ISO 12006-2 has been under revision and it is likely that a new edition of the ISO will be published in 2015. Uniclass2 closely matches the framework is currently the only classification to do so.
