This is the latest in our quarterly updating programme for Uniclass. It includes updates to eight tables and is predominantly for the addition of new classifications and corrections to existing classifications.

We aim to minimize changes to existing codes and classifications, but we always take feedback from users into account. Any changes are the result of this input, combined with our own ongoing review.

Updates to existing tables

This update includes some extensions of the codes in the ‘Elements/ functions’ table. We have been in consultation with various organizations and the Uniclass Advisory Board (UAB) to ensure that we are matching requirements. Any feedback is much appreciated.

Changes to the ‘Tools and Equipment’ table have been made to reflect maintenance carried out in the rail sector, and the ‘Systems’ table includes new codes for use in the structure of pavements generally. The ‘Systems’ table also includes corrections to the classifications, and a rearrangement of the classifications for shading and screening systems, in response to user feedback.

The changes to the ‘Entities’, ‘Activities’ and ‘Spaces/ locations’ tables include new codes requested by users in different sectors. The changes in the ‘Products’ table include new codes requested by users and corrections to classifications.

For the ‘Project Management’ table, we have continued our work with the Ministry of Justice and have added a number of new codes to match their requirements. Full details of these changes are detailed in the revisions sheets and the Excel change log.

Continuing input and feedback

Between updates, we liaise regularly with a growing number of individuals and organizations using the tables in order to provide support and evaluate requests for new codes. We are grateful to all of the organizations that we have worked with for their input. As we share details of this activity, industry professionals can learn more about who else is using the tables, what purposes they are using them for, the range of changes to expect and the reasons for those changes.

The work of maintaining and enhancing Uniclass to continually support the needs of those operating in the built environment is an ongoing exercise. We welcome comments and input from all sectors in the construction industry via the new web pages – https://uniclass.thenbs.com/feedback.

Changes to published versions

Status and revision information is available alongside each Uniclass table. Each information sheet (PDF) provides a summary of the changes made, as well as code-by-code details. A full list of all changes is also available in the Excel change log.
