Newsroom
All the latest NBS and industry news and stories
2020 has been a year like no other. Many design team members have spent the majority of the year working from home, leading to a greater need for digital collaboration. Due to this shift in working practices, NBS Chorus has become the specification writing platform of choice. Join our next webinar hosted by Dr Stephen Hamil, Innovation Director at NBS, to explore how digital collaboration has become an essential part of the specification writing process. Stephen will also be joined by Sally-Anne Balmer, Architect and Technical Content Team Lead at NBS who will provide insight into the content authoring process at NBS.
