Specifications Software

Specifications published here may be edited using two approaches: 

    • using a common word processor (Word, WordPerfect), supplemented with SpecMacros software,
    • using NBS Chorus web-based editing software, 

NBS Chorus

NBS Chorus is an online (web-based) specification editing tool, which runs on any platform (Windows, Apple) and any device that supports a browser (PC, tablet, smart phone).  Using Chorus you can access any of the specifications published by NBS Canada (Digicon), which are always kept up-to-date on the server. Chorus enables coordination and links with a BIM model via a Revit plug-in, greatly reducing the risk of uncoordinated specs and drawings.  As a web-based application, Chorus enables collaboration real-time inside your organization, or externally with clients and other consultants.

Using a common word processor requires editing files manually using Microsoft Word. To assist with this mode, Digicon offers SpecMacros; read the link below to find out more.
