Uniclass 2015 and NBS services

27 October 2017

Uniclass 2015 is a unified classification for the UK industry covering all construction sectors. It contains consistent tables classifying items of all scale from a facility such as a railway down through to products such as a CCTV camera in a railway station.

Here we outline the considerations required across a range of NBS services and our plans to incorporate Uniclass 2015:

NBS National BIM Library

All digital objects on the NBS National BIM Library now include Uniclass 2015 parameters. As updates to the Uniclass codes are issued by NBS via the three-monthly updating programme, these will be applied where relevant to the digital objects in the NBS National BIM Library. Object versioning is used to indicate that the Uniclass 2015 parameter has changed. In addition – changes to objects are brought to the users attention when using the My Library tool that also helps to sort and filter your most-used digital objects.

BIM objects currently contain four different parameters – NBSReferenceUniclass2Description and NBSDescription.

Taking this 
BIM object as an example; NBSReference and NBSDescription are parameters for the code and title used in NBS Create. These differ as NBS Create predates Uniclass 2015 by five years.

Uniclass2 information will be removed from our BIM objects going forward and the parameters Uniclass2015VersionUniclass2015Reference and Uniclass2015Description will be used to house Uniclass 2015 details. NBSReference parameter will remain to ensure integration between the object library and the NBS specification tools remains intact for continuing co-ordination between the model and drawings

NBS Plus

NBS Plus is a library of manufacturers' product information, linked to specific clauses within the NBS specification software products - NBS Create, NBS Building, NBS Landscape and NBS Scheduler. For manufacturers appearing in NBS Create, their product information will be featured with the relevant Uniclass 2015 codes in the NBS Create specification output as part of the NBS Create development noted below.

NBS Create and the NBS Plug-in for Autodesk Revit

In early 2017, NBS Create was updated to include Uniclass 2015 codes within the COBie export. Our work continues with NBS Create customers to enable us to support their specification needs on projects that require use of Uniclass 2015. We are doing this via an NBS Open Beta Programme (ProjectU15). Participating beta customers receive and give feedback on a series of Uniclass 2015 themed NBS Create beta releases. Users have prioritised the need for Uniclass 2015 codes in the printed specification output.

Participants are also feeding into a beta programme for the NBS Plug-in for Autodesk Revit. Beta releases of the plug-in are following a similar Uniclass 2015 theme to support users in coordinating their models and specifications using Uniclass 2015 codes. In addition, users can beta test new tools for bulk stamping Uniclass 2015 codes into digital object libraries.

Visit the Project U15 Open Beta webpage to find out more or to get involved.

As one of the essential tools referenced on bim-level2.org, Uniclass 2015 will eventually be the classification that is used across the UK construction industry. As NBS and other software providers adjust their applications to support its use, the need to classify and specify on current projects is still enabled using the current version of NBS Create.

NBS Building, NBS Scheduler and NBS Domestic Specification

NBS BuildingNBS Scheduler and NBS Domestic Specification will continue to use Uniclass 1.4 codes – a material-based work section classification. Although this classification system is no longer maintained, these codes remain suitable for use on projects. Uniclass 2015 is a systems-based classification and is not currently being considered for implementation within these NBS specification solutions.

RIBA Product Selector

RIBA Product Selector currently utilises CISfB. Decisions on any future use of Uniclass 2015 will be considered as part of ongoing product review.

RIBA CPD

All existing and new RIBA Approved CPD materials are now mapped to Uniclass 2015 as standard. In the future this will provide opportunities to consider developments including searching RIBA CPD by Uniclass 2015 code and other Uniclass 2015 related options that users may request in the future.
