01 October 2025

This release includes updates to four tables: Elements/ functions, Products, Spaces/ locations and Systems.

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.
