Kjell Vidar started working with BIM already at school in 1999, there was the ArchiCAD tool, after which he worked with AutoCAD Architecture and Revit as BIM tools. Kjell Vidar has subsequently worked with several different companies as a consultant with a very wide range of projects.

After working at both the Rikshospitalet and the architectural office Niels Torp Arkitekter, he made his way to the software industry to learn more about the tools, the development and to master as many design tools as possible. There, he was on many courses and even started to train others and put up the strategy around BIM.

He started working at NSW in April 2011 and has been the architect's BIM responsible for most BIM projects. In January 2020, he was also given responsibility for digitization in the office.
