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

Our work with the Environment Agency has been concentrated on the Project Management table in this period. We have also worked with the fish protection group at the Environment Agency, which has resulted in some additions to the fish pass systems. Other additions have been made following requests from Transport for London, Transport for New South Wales and the WICHS group of BIM4Water.

In the Products table, we have added codes to match templates in SFG20 and made some alterations to some of the drainage codes as a result of our work with the WICHS group, in order to better reflect the types of product used generally. We have also taken the opportunity to correct all the references to GRC and GRP which had been incorrectly given. We have also responded to a number of requests to amend some products to clarify the classifications.

In the Systems table we have added new fish pass systems and made some additions in the structural classifications. We have also moved the duplicate classifications for flashing and weathering to a new group to remove any ambiguity.

The other tables with changes include the Tools and equipment table, Activities table, Elements/ functions table, Spaces table and Entities table.

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.
