The Construction Leaders’ Summit: Building Better

At NBS, we're committed to providing the construction industry with the tools and resources needed to help build a better and more sustainable future. 

As part of this commitment, we held The Construction Leaders' Summit: Building Better, on Wednesday 29th September.

The one-day online event was for anyone involved in the design, supply, and construction of the built environment, looking to learn about and discuss the future of construction and how we can help improve it.

The event brought together leading figures from the construction industry who focused on building a more sustainable future and the digital tools and working practices needed to achieve this. 

The event is available to watch on demand now! Sign up to see the presentations from our fantastic speakers.
