This is the latest in our quarterly updating programme for Uniclass. It includes updates to four tables.
We have worked with Transport for New South Wales (TfNSW) to provide new product, system and element/function classifications to cover subsurface asbestos encapsulation (typically used to provide containment on highways type projects where there are known areas of contamination for which disturbance should be minimized).
Additionally, following the request from a manufacturer, the ‘Products’ table has been extended to include classifications for railway track and railway depot equipment under the ‘Power supply products’ grouping. This resulted in the addition of two new 6-digit sections as well as four new 8-digit object codes to cover changeover panels, fuse enclosures, track isolating switches (remote controlled) and power supply status relays.
The Royal Cornwall Hospitals NHS Trust has been using Uniclass to classify their assets as part of their Building Information Modelling (BIM) journey, ensuring consistency and clarity across their digital estate. To allow for the classification of rooms with healthcare-specific functions -essentially clinical environments – we extended the ‘Spaces/ locations’ table in collaboration with the Trust, adding a total of five new codes.
Further work is underway with:
- Environment Agency.
- Roads and Transport Authority in Dubai.
Updates to the Uniclass tables are a result of external input from users and internal development roadmaps. Full details of changes are detailed in the revisions sheets and the change logs.
Previously used codes
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, and this sometimes means that a code is moved to another location in the tables – or deleted completely.
Following feedback from government department users of Uniclass, we have made every code that has been used since Uniclass was first published in 2015 available, together with information on the codes that they have been replaced by, where appropriate. Deleted and revised codes are now included in the site search facility, and a separate Excel file that lists all the withdrawn codes is also available.
Continuing input and feedback
Between updates, we regularly liaise 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 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 website – https://uniclass.thenbs.com/feedback.
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.
