2019/08/13: An Update On Uniclass 2015
Uniclass is a consistent classification structure for all disciplines in the construction industry. It contains tables classifying items of any scale from a large facility such as a railway, down to products such as a CCTV camera in a railway station.
It’s an essential way of identifying and managing the vast amount of information that’s involved in a project, and it’s a requirement for BIM projects, as set by the BS EN ISO 19650 series of standards.

Uniclass2
Uniclass 2 was 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.
