Uniclass 2015 - April 2021 update

This is the latest in our quarterly updating programme for Uniclass 2015. It includes updates to nine tables.

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

During the last three months, our work with the Department for Education, the Environment Agency and the Palace of Westminster refurbishment team has continued. As a result, there are more additions to the tables.

Having added classifications for most of the internal educational spaces in the January 2021 update, this update includes new codes for external educational spaces. We have also added classifications for many new pieces of information in the Project Management table. For the Environment Agency, we have added classifications for more detailed assets, mostly in the Spaces/ location table.

In addition to the work specific to these organizations, we have reorganized the section dealing with mineral boards and sheets in the Products table (we were asked to accommodate a new code and had run out of numbers). We have also moved the sections for ‘Deaerators’ and ‘Expansion compensators’ from the subgroup for ‘Air and fume distribution products’ to the subgroup for ‘Pipe, tube and fitting products’, following a query raised by a user. Other new codes have also been added, following requests from users. We are currently developing two new tables: ‘Process activities’ and ‘Properties and characteristics’, and we will be publishing draft proposals for comment in the near future.

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 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 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 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.
