Uniclass2 development release classification
Uniclass is a voluntary classification system for the construction industry that can be used for all aspects of the design and construction process, including organising documents in libraries, structuring project information, cost information, specifications, and so on. It was created in 1997 by Construction Project Information committee (CPI).
Uniclass 2 was issued following criticism that Uniclass was not genuinely unified, was inconsistent, had poor integration of civil engineering and building works and was essentially a paper-based system.

The classification is available in other formats from the CPI website.
NB: Following feedback received about Uniclass 2, changes were made, and a new version, Uniclass 2015 released. The most significant change is the removal of the Work Results table.
