VIDEO: Drone for Fehmarnbelt tunnel

Dane Grace, one of the world's most talented drone pilots, has flown his drone over the German and Danish construction sites for the Fehmarnbelt Tunnel, set to be the world’s longest immersed tunnel.

In perfect weather conditions, internationally renowned drone pilot Dane Grace flew his drone over the German and Danish construction sites for the Fehmarnbelt tunnel.

On his first visit to the construction site, he was able to film the construction of the tunnel element factory on the Danish island of Lolland. Now he was back on site. His spectacular footage shows the progress of work on the tunnel portals in Germany and Denmark, as well as the production of tunnel elements in the large factory in Rødbyhavn.

The Fehmarn Belt Tunnel could open by mid-2029. Around 1,500 tonnes of reinforcement for casting the concrete tunnel elements are produced weekly for the 17.6km-long structure. Formwork specialist Peri supplied 10,000 tonnes of formwork needed for construction of tunnel elements.

The individual elements will eventually be lowered into place and connected together on the bottom of the Baltic Sea, according to the client Femern, part of the 100 per cent state-owned company Sund & Bælt. Femern is tasked with planning, building and operating the fixed link across the Fehmarnbelt between Denmark and Germany.

The two contractor consortia, Fehmarn Belt Contractors (FBC) and Fehmarn Link Contractors (FLC), are responsible for the construction of the tunnel that will run between Rødbyhavn on Lolland and Puttgarden, a ferry harbour and a village on the German island of Fehmarn.

    The Nordhavnsvej – Vej- og Tunnelentreprise (Nordhavnsvej) project is Copenhagen’s largest infrastructure project in the last 50 years. The 1.65km-long route will eventually link the Danish capital’s northern port area with the Helsingør motorway. It runs through a very densely built urban area, in parts at depths of up to 22m. One particular challenge regarding the execution was planning the course of the tunnel because the underground structure also crosses a very busy railway line.

    It may be early days for using drones – unmanned aerial systems (UAS) -- to map construction sites, but technology and legislation are moving in that direction. At the moment drones can fly within only a 500m radius of the ‘pilot’ standing on the ground, making the flight area a 1km diameter. This is the key limiting issue for any sector, especially road construction, says Jonathan Gill, a robotics engineer and a qualified drone pilot for the past seven years. The logic is that a drone remains withi
