A joint venture between Hochtief and Vinci has been awarded the contract to build a 4.4km underground line and five underground stations in Copenhagen.
Under the six-year design and build contract worth €460M (£408M), the JV will construct dual tunnels using two earth-pressure tunnel boring machines, along with five underground stations and two crossover structures that will make up Sydhavn Metro Line (Line 4).
The project also includes electrical and mechanical systems, architectural interior works, and in-tunnel ventilation for the 5.5m diameter tunnels. It is expected to open in 2024.
Hochtief Infrastructure Europe West executive vice president Riku Tauriainen said: “We are very pleased to have this opportunity of demonstrating our tunnelling expertise in Copenhagen again. This contract continues our successful activities in the Danish infrastructure market. We are looking forward to working once again together with Vinci.”
Vinci Construction Grands Projets operations director northern Europe, British Isles and Americas Eric Chambraud added: “Eighteen years after the delivery of the Øresund tunnel and two years after the award of the Femern tunnel, it’s our honour to continue to work for the Danish people’s daily mobility with a new line of underground metro, especially with our historical partner Hochtief.”
According to Hochtief and Vinci, they have brought together their skill sets in design, project management, and underground works to build the new metro line. For the first time in Denmark, 3D modeling will be used extensively as early as the bid-submission phase by the consortium.
In Copenhagen Hochtief, in a joint venture, is currently constructing the Metro Cityringen Branch-off to Nordhavn tunnel project, as well as a 4km district heating tunnel.
