MAPPINGS AND TRANSLATIONS

With the support of our partners, we aim to make Uniclass more accessible.

Uniclass code mappings and relationships

There are other classification schemes and related systems in use in the global construction industry, and sometimes it’s necessary to use more than one for specific purposes in a project.  Uniclass aims to make this process easier, by providing associations between Uniclass codes and other classifications.

At the moment, we publish the relationships between Uniclass and NRM1 (New Rules of Measurement) from the Royal Institution of Chartered Surveyors.  Every Uniclass code with an equivalent code in this scheme will display the relevant NRM1 code on its page.

In addition, we have worked with the Government and Industry Interoperability Group to develop relationships from Uniclass to IFC 2x3 TC1. Read more about the relationships between Uniclass and IFC.

We will consider mappings to other schemas and classification systems, as they become needed, to support users around the world.

 

Uniclass in translation

Uniclass was originally developed with funding from the UK government, and so was published in English only.  However, as usage becomes international, users around the world prefer to use it in their own language.  As such we’re aware of organizations elsewhere having prepared their own translations of classification headings, though of course the codes themselves remain consistent wherever you are.

These translations have not been published by NBS as part of Uniclass, but if you have prepared a translation or are interested in doing so, we would be happy to hear from you.
