Choosing the correct classification system is an essential decision when coordinating construction project information. In addition, when managing a portfolio of assets in the built environment, the choice of classification system is of increasing importance.

Example top level classifications from Uniclass 2015 tables

Uniclass 2015 is a unified classification for the UK industry covering all construction sectors. It contains consistent tables classifying items of all scale from a facility such as a railway down through to products such as a CCTV camera in a railway station.

This new classification system was a key deliverable of the Innovate UK funded BIM Toolkit project. As part of this project, NBS worked with experts from across the industry to develop Uniclass 2015. This builds on previous versions and developments of Uniclass by CPI, but significantly extends the scope and responds to industry feedback to this previous work.

Uniclass 2015 provides:

  • A unified classification system for the construction industry. For the first time, buildings, landscape and infrastructure can be classified under one unified scheme.
  • A hierarchical suite of tables that support classification from a university campus or road network to a floor tile or kerb unit.
  • A numbering system that is flexible enough to accommodate future classification requirements.
  • A system compliant with ISO 12006-2 that is mapped to NRM1 and supports mapping to other classification systems in the future.
  • A classification system that will be maintained and updated by NBS.
  • A ‘digital-first approach’ where the classification is in a central database and accessible through an intuitive user interface or web services.
