Uniclass 2015 is a unified classification system for all sectors of the UK construction industry. It contains consistent tables classifying items of all scales, from entire systems such as a railway to individual product items such as anchor plates, flue liners or LED lamps. Originally released in 1997, Uniclass allowed project information to be structured to a recognised standard. The original version was later heavily revised, to make it more suitable for use with modern construction industry practice, and to make it compatible with Building information modeling (BIM) processes. History Uniclass was created in 1997 by the Construction Project Information Committee (CPIC), a UK industry organisation with representatives from key institutions including the Royal Institute of British Architects and the Royal Institution of Chartered Surveyors. A voluntary standard classification system for the construction industry, it was intended to help organise information throughout design and construction processes. A standard classification facilitates interoperability between different systems. Early versions were criticised for not being unified, for inconsistencies between the labelling and depth of tables, for poor integration of civil engineering and building works, and for being an essentially paper-based system. Uniclass 1.4 was superseded by Uniclass 2 in 2013. Uniclass 2015 development Led by the National Building Specification (NBS), experts from across the industry developed Uniclass 2015, extending the scope and responding to industry feedback on Uniclass 2. Uniclass 2015 provides: a unified classification system for the construction industry - for the first time, buildings, landscape and infrastructure could be classified under one unified scheme a hierarchical suite of tables that supported classification from a university campus or road network to a floor tile or kerb unit a numbering system flexible enough to accommodate future classification requirements a system compliant with ISO 12006 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. Uniclass 2015 provides a means of structuring project information essential for the adoption of BIM. Information about a project can be generated, used and retrieved throughout the built asset life cycle. Uniclass 2015 was carefully structured to be in accordance with ISO 12006-2 Building construction – Organization of information about construction works – Part 2: Framework for classification. It is therefore particularly suited to use in an international context, mapping to other similarly compliant schemes around the world. Application Uniclass 2015 is divided into
