This is the latest in our quarterly updating programme for Uniclass 2015. It includes some major updates to eleven 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 we have been working with teams from the Department for Education, the Environment Agency, the Palace of Westminster and the Water Industry Classification and Hierarchy Standards (WICHS) group of BIM4Water. As a result there are a substantial number of additions to the tables.

In particular, there are many new classifications in the Spaces/ location table for educational spaces. We have amended and added to the Complexes and Entities tables to better match the requirements of the water industry, and added Systems for water treatment. For the Environment Agency we have added clauses to the Entities, Spaces/ location, Elements/ functions, Systems and Products table. Our work with the Palace of Westminster team has led to the reorganization of the Products table in the Pr_40 group and the addition of codes to match their heritage requirements.

In addition to the work specific to these organizations, we have reorganized part of the Pr_75 group following feedback from 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.
