Consultants Mott MacDonald and Arup were amongst the firms to miss out on the mechanical and electrical design systems contract for the Fehmarnbelt road and rail crossing between Denmark and Germany.
Project promoter Femern has awarded the contract to a joint venture between Danish consultant Hansen & Henneberg and German energy consultant Pövry Infra.
The contract includes producing the designs for power supply, lighting, communication, ventilation and intelligent traffic control within the tunnel. The joint venture will also work with Femern during the tendering phase of the contract and assist during the construction.
Construction of the EUR 5.1bn (£4.4bn) 18km long tunnel is expected to begin in the summer of 2014 and is due to open in 2020.
