£2.6bn Fehmarnbelt construction deal sealed

Fehmarnbelt Link

The joint venture appointed to build the Fehmarnbelt project has signed contracts with the Danish government to design and build  what will be the world’s longest immersed road and rail tunnel.

The 18km Fehmarnbelt project will link Denmark and Germany and will cut the journey between the two coasts to just 10 minutes by car and seven minutes by train compared to the current travel time of one hour by ferry or a 160km detour via the Danish region of Jutland by car.

The Vinci led joint venture – called The Femern Link Contractors – has won three contracts worth £2.6bn, the overall project cost is around £5.6bn. Two contracts are for the construction of the tunnel and a factory to build the precast tunnel element. The other is to build the portal and ramps. Aarsleff is the lead company on the latter contract, worth £380M.

The joint venture comprises Vinci Construction Grands Projets, Per Aarsleff, Royal Bam Group (with its three arms Bam Infra, Bam International and Wayss and Freytag Ingenieurbau), Solétanche-Bachy International, CFE and Max Bögl Stiftung. In addition, it has appointed Dredging International (Deme Group) as subcontractor for the tunnel contracts and Cowi as consultant for all three contracts.

Construction is expected to start at the beginning of 2018 and will take around 8.5 years.
