Newsroom
All the latest NBS and industry news and stories
We've just launched NBS Chorus Designer, a new cost-effective offering for organisations who want to coordinate the information in models, drawings and schedules with their specifications but don't have enough NBS Chorus seats for everyone in the office to collaborate. Those using the designer roles can also view the NBS guidance and add specification notes in addition to annotating the information in the model directly from the project specification.
Join our webinar with Dr Stephen Hamil (Innovation Director at NBS) to learn more about NBS Chorus Designer and how it will benefit your organisation to work efficiently and collaborate seamlessly on projects.
Chris Dixon from Franklin Ellis Architects will join the session to demonstrate how his organisation uses NBS Chorus Designer to sync their information and speed up project delivery.
There will be an opportunity to ask questions during the session.
Speakers
Dr Stephen Hamil, Innovation Director at NBS
Chris Dixon, Associate Architect and BIM Manager at Franklin Ellis Architects
