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

In this update, we have included some new codes for dams in the ‘Complexes’, ‘Entities’ and ‘Spaces/ locations’ tables. This follows a request from a user and consultation with the Uniclass Advisory Board and other users such as the Environment Agency.

Our consultation with the Water Industry Classification Hierarchy Standards (WICHS) group has now allowed us to add new codes to the ‘Complexes’, ‘Entities’ and ‘Elements/ functions’ tables, and further new Systems codes will follow in the next update in October.

We have been working with some tunnel experts and National Highways to add new codes for the excavation, construction and management of tunnels. These are included in the ‘Entities’, ‘Activities’, ‘Elements/ functions’, ‘Systems’ and ‘Products’ tables.

Additional changes have been made in the tables following feedback from users, including: amendments to the survey classifications in the ‘Activities’ table; codes to match the requirements for Passivhaus in the ‘Project Management’ table; new codes for bridges in the ‘Systems’ table and codes for equipment used in crematoriums in the ‘Products’ table. 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 that use 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 new feeback page.

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.
