Model and specification integration

Model and specification integration

Oct 26, 2023 |Chris Vickers

As part of the product development process at NBS, we listen carefully to customer feedback and feature enhancements that can complement and improve established internal design processes.

A set of shared parameters has been identified and developed that allows designers to provide additional information on drawing outputs, for the purposes of further identification and descriptive notation. The features of this ‘enhanced integration’ are introduced below.

Object association

The new BIM Library in NBS Source has tens of thousands of high-quality Revit® layered and component families that are free to download. Using the NBS Plug-in for Autodesk® Revit®, these objects can be downloaded from NBS directly into your design and quickly associated to NBS Chorus.

Depending upon the object type, the integration process will differ slightly:

  1. Layered objects
    Example families include wall, floor and ceiling objects. The nature of these objects requires two levels of association, first at object type and then the constituent materials.
  2. Component objects
    Example families include door and sanitaryware objects. Only type association is required.

Multiple objects and types can be associated to the same clause in NBS Chorus. Equally, once a Revit® type has been associated, all other instances of that type are linked.

Enhanced shared parameters

The enhanced functionality in the NBS Plug-in for Autodesk® Revit® enables the synchronization of crucial information from NBS Chorus to modelled objects. These shared parameters can be easily integrated into your drawing annotations and schedules to provide further clarity on product identification.

Parameters are automatically embedded into the model and their applicable object(s) at the point of association and are summarized in Table 1 below.

Property name1 Type Description

NBSChorusClauseID Text Read-only property. Clause identification in NBS Chorus.
NBSChorusCode Text Classification system number.
NBSChorusDescription Text Clause description in NBS Chorus.

NBSChorusPrefix Text Custom clause prefix field.
NBSChorusProdRef Text Product identification as per manufacturer information.
NBSChorusProjectID Text Read-only property. Project identification in NBS Chorus.
NBSChorusSpecificationId Text Read-only property. Specification identification in NBS Chorus.
NBSChorusSuffix Text Custom clause suffix field.
NBSChorusURL URL Link to overall specification.

NOTE1: Equivalent shared properties are available with a “_mrtrl” suffix for Revit® materials.

The information is authored and controlled within NBS Chorus and automatically synchronized with the model, which speeds up processes and reduces the risk of information not being coordinated. Where information has been updated within NBS Chorus, warnings and error messages are displayed on the model tab notifying the user that the two are out of sync and that corrective action is required.

NBS annotation tags for Autodesk® Revit®

NBS has several different annotation families appropriate for regional differences and applicable content sets in NBS Chorus:

  • CAWS tags for specifications based on the UK CAWS content sets.
  • OmniClass tags for specifications based on the Canadian CMS and NMS content sets.
  • Uniclass tags for specifications based on the Australian and UK Uniclass content sets.

The default tags can be found in the NBS tab as shown in Figure 4 below. Alternatively, they can be found in the following locations once the NBS Plug-in for Autodesk® Revit® is installed:

Revit® 2023 onwards
C:\ProgramData\Autodesk\ApplicationPlugins\NBS.bundle\Contents\Revit2023\Redistributables\tags\NBS Chorus

Revit® 2020–2022
C:\ProgramData\Autodesk\ApplicationPlugins\NBS.bundle\Contents\Revit2020-2022\Redistributables\Tags\NBS Chorus

The latest NBS Shared Parmeter file contains all the necessary parameters to create custom annotation tags.

Visqueen launches Ultimate Self Adhesive Membrane for hydrocarbon and VOC-contaminated sites

The construction industry faces growing challenges when building on increasingly complex brownfield sites. Alongside the need for effective waterproofing, developers and contractors must now address a wider range of ground contaminants, including hydrocarbons, volatile organic compounds (VOCs), and hazardous ground gases, while maintaining programme efficiency and installation quality. Against this backdrop, Visqueen has expanded its gas protection and waterproofing portfolio with the launch of Visqueen Ultimate Self Adhesive Membrane, a new hydrocarbon and VOC-resistant self-adhesive tanking membrane. Developed as the latest addition to the Visqueen non-foil gas barrier range, the new membrane combines proven gas barrier and waterproofing performance to help specifiers address multiple site challenges with a single solution.

Siderise: Helping to bridge the gap between Gateway 2 approval and on-site fire protection

While the new building safety regime hasn’t fundamentally changed what requirements higher-risk buildings (HRBs) must meet to comply with the Building Regulations, it has significantly increased the breadth, depth and volume of evidence that must be supplied to demonstrate this. As a result, project teams have had to adapt the way they work and even look beyond their roles to understand how their actions may impact the next Dutyholder in the chain. For specifiers, this can include considering what supporting services are offered with life safety-critical elements to enable correct design, installation and maintenance. Early engagement with manufacturer technical specialists can help identify any practical challenges that may arise onsite. Then, during construction, these services can help support the translation of design intent into reality so that buildings are safe for occupation.

RIBA CPD for Architects: Understanding Flooring Specification and Detailing

For architects and specifiers, flooring details can have a significant impact on the safety, accessibility, durability and overall performance of a building. Yet the technical considerations surrounding stairways, floor transitions, and floor finishes are not always straightforward.
