A joint venture of German construction firm HOCHTIEF and French concessions and construction company VINCI has won a €460m contract from Metroselskabet to design and build Sydhavn Metro Line (Line 4) in Copenhagen, Denmark.
Metroselskabet has awarded the contract to an equal-stake joint venture consisting of HOCHTIEF Infrastructure and VINCI Construction Grands Projets. HOCHTIEF will be the technical leader of the joint venture.
The six-year design-and-build project for the southern metro line involves the construction of dual 4.4km tunnels using two earth-pressure tunnel boring machines (TBM), along with five underground stations and two crossover structures, electrical and mechanical systems, architectural interior works, and in-tunnel ventilation.
The tunnels will have an interior diameter of 4.9m and an exterior diameter of 5.5m.
The metro network extension south of the Danish capital (Sydhavn or M4) will be connected to the main ring line (Cityringen).
Both companies will combine their skills in design, project management and underground works to build the new metro line.
For the first time in Denmark, the consortium will use 3D modelling extensively as early as the bid-submission phase.
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 Northern Europe, British Isles and Americas operations director Eric Chambraud said: “Eighteen years after the delivery of the Oresund 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.”
HOCHTIEF and VINCI have been collaborating on major projects since long, including on metro projects such as the one in Athens.
Recently, the two companies have joined forces on projects in Greece and in other countries outside Europe.
In a joint venture, HOCHTIEF is currently executing the Metro Cityringen Branch-off to Nordhavn tunnel project in Copenhagen.
Since May 2016, the VINCI Group has led a joint venture for the construction of an 18km Femernbelt, the world’s longest underwater tunnel that will link Denmark and Germany.
