This is the latest in our quarterly updating programme for Uniclass. It includes updates to ten tables.

We have been working with the Ministry of Justice on classifications for the ‘Complexes’ and ‘Spaces/ locations’ tables to improve the content for the prison estate. We have also worked on information requirements in the ‘Project management’ table.

Further work has been underway with:

  • The Environment Agency (on orifice flow control structures and eel passes);
  • National Highways (to improve the content for bridge systems); and
  • Network rail and Transport for London (to include additional codes for overhead line equipment).

The ‘Roles table’ has been updated to remove the letters originally included to match the National Annex to ISO 19650-2, and to add codes to align with BS 8644-1.

Other changes are a result of feedback from users; full details of these changes are detailed in the revisions sheets and the Excel change log.

Previously used codes

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, and this sometimes means that a code is moved to another location in the tables – or deleted completely.

Following feedback from government department users of Uniclass, we have made every code that has been used since Uniclass was first published in 2015 available, together with information on the codes that they have been replaced by, where appropriate. Deleted and revised codes are now included in the site search facility, and a separate Excel file that lists all the withdrawn codes is also available.

Continuing input and feedback

Between updates, we regularly liaise with a growing number of individuals and organizations using the tables in order to provide support, and to 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 comment and input from all sectors in the construction industry via the website.

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.
