Uniclass (Unified Classification for the Construction Industry), published in 1997 in UK by the Construction Project Information Committee (CPIC).

This is fast becoming Uniclass2 as of 2013. A change that sees the 15 original Uniclass tables reduced to 7 (although more may be added). Uniclass2 features increased scope, depth and consistency of information covering all aspects and disciplines of the built environment, including infrastructure and process engineering.

What follows is the original entry for the initial Uniclass system (note that Uniclass2 should be used instead[citation needed], see the "External links" section):

Uniclass is a new classification scheme for the construction industry. It is intended for organising library materials and for structuring product literature and project information. It incorporates both CAWS (Common Arrangement of Work Sections for building works) and EPIC (Electronic Product Information Co-operation), a new system for structuring product data and product literature.

The Construction Industry Project Information Committee (CPIC), representing the four major sponsor organisations (the Construction Confederation, the Royal Institute of British Architects, The Royal Institution of Chartered Surveyors and the Chartered Institution of Building Services Engineers), and the Department of the Environment Construction Sponsorship Directorate were responsible for commissioning and steering the project, which was developed by NBS on behalf of CPIC.

Uniclass comprises 15 tables, each of which represents a different broad facet of construction information. Each table can be used as a "stand alone" table for the classification of a particular type of information, but, in addition, terms from different tables can be combined to classify complex subjects.
