2015/07/09: An Update On Uniclass2015

UNICLASS 2015 is a development of CPIc’s UNICLASS 2 and is now cited in the UK National foreword to ISO 12006-2 Building construction – Organisation of information about construction works as the UK response to that International Standard. This has the important effect of elevating its status from that enjoyed by previous versions of UNICLASS.

In 2014 CPIc passed its intellectual copyrights in UNICLASS, including all the development work in UNICLASS 2, to the UK Government for beneficial and government backed and financed development and completion for use with BIM. This has resulted in the UNICLASS 2015 classification within the BIM Toolkit published by NBS. After a period of publication in beta this has now moved to its first formal post-beta issue for use. Development will continue, however, so please do comment/feedback from your own observation and particularly from use on design and construction projects.

Whilst CPIc continues and can answer questions about its other documents or legacy versions of UNICLASS, it seems only appropriate to refer enquiries about use of the new UNICLASS 2015 to the NBS.
Questions will very likely be answered by this article and the tool provided for keyword searches

If, having read the article you still have questions do contact the author of that page Sarah Delany at NBS (Sarah.Delany@theNBS.com).






Uniclass 2 was been developed to produce a classification system for structuring information that is freely available for all participants throughout the life cycle of a project and beyond, which is endorsed by all construction and property bodies and professional institutions. It is dynamic, available online in various formats and managed by a team of experts who will monitor requests, update and control versioning.

The tables available in this tool are ready for use in applications to test their usability. Where missing classifications are identified they should be notified to the CPI Committee Secretary directly at info@cpic.org.uk so that they can be added centrally for all to use. All comments and feedback are invited so that a national standard can be achieved for use by all.
