Align JV (HS2) Colne Valley Viaduct Completion

Drone Tech Aerospace has been proud to work with the Align JV team on the HS2 project at Denham and the Colne Valley Viaduct since 2019, before the first ground was broken on site. DTA's services began with topographical land surveying by drone on the greenfield site, establishing the baseline data needed for design and construction planning.

DTA's work on the site progressed over the following years to regular drone photography and video for site progress monitoring and PR. The Colne Valley Viaduct site is now one of the most surveyed and monitored construction projects in DTA's portfolio, reflecting the scale and complexity of the works and the partnership built with the Align JV team over a multi-year programme.
