We are proud to have been working with the Align JV team on the HS2 project at Denham and the Colne Valley Viaduct since 2019, before first ground was broken.
DTA's services started with initial Drone Topographical Land Surveying for Construction on the greenfield site and progressed on to Drone Photography and Video for site progress monitoring and PR.
The site is now one of DTA's most surveyed and monitored construction sites as one would expect for such a complex construction project.
