Share knowledge

Built for teams that write preliminaries
Get the benefits of NBS Chorus in a cost-effective package built for Quantity Surveyors, Project Managers and consultancies that write preliminaries but do not need access to every specification content library.
"Since we started using Chorus, we’ve benefitted from increased efficiency across all our projects. Preliminaries are written faster than ever before, and we can now easily ensure all project documentation is standardised and consistent."
"NBS Chorus is the future. It's quick and easy to use and has all of the functionality I need. The fact that you can edit the spec in Revit is very powerful as it reduced the chances of contradictory information in the model or specification...and it bridges the gap between Mac and PC, which could be the holy grail!"
