28 October 2020

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.

Excel changes file

We have included an Excel spreadsheet detailing the code and classification changes in the October 2020 update; please let us know if this format is helpful in managing the updating of the processes which use Uniclass 2015.

Updates to existing tables

Throughout the tables, we have added and amended codes as a result of requests and feedback from users and experts.

We have started to extend the classifications in the ‘Elements/ functions’ table in this update, following input and discussion with the team at Transport for New South Wales. We will continue to explore appropriate ways of including new classifications in this table, so if you have any suggestions please let us know.

The ‘Systems’ and ‘Products’ tables have a number of additional classifications for items, including: panel walling, access control gates and transport management systems; some new products that have been added to map to the ‘Energy’ technology list; bollards and impact protection devices for use in car parks; and access control gates. We have added some new codes in the Spaces/ location table, Systems table and Products table for the Environment Agency, including trash rakes, navigation aids, canoe passes and spillway funnels.

Changes to codes and classifications

Our main priority when updating the Uniclass classification tables is to avoid changing existing codes and classifications as far as possible. We add new codes and amend existing classifications in response to feedback, but some feedback causes us to review the existing tables and to identify anomalies. This may lead to us deleting a classification because it is duplicated elsewhere, and we use the revision sheets to point users to the correct location. In other cases, we can see that the groupings of some classifications are incorrect, and so we have to resolve these inconsistencies.

Full details of these and other changes are detailed in the revisions sheets.

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 to evaluate requests for new codes. We are grateful to all 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 2015 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 uniclass2015@theNBS.com.

Changes to published versions

Status and revision information is available alongside each Uniclass 2015 table. Each information sheet (PDF) provides a summary of the changes made, as well as code-by-code details.
