The client Metroselskabet has awarded the contract to an equal-parts joint venture consisting of Hochtief Infrastructure and VINCI Construction Grands Projets.
Hochtief will be the technical leader of the joint venture. The EUR 460 million contract was signed on March 9, 2018 in Copenhagen.
This design and build project for the southern metro line is a six-year mandate that calls for the construction of dual 4.4-kilometer tunnels using two earth-pressure tunnel boring machines (TBM) along with five underground stations and two crossover structures. The project also includes electrical and mechanical systems, architectural interior works, and in-tunnel ventilation.
The tunnels will have an interior diameter of 4.9 meters and an exterior diameter of 5.5 meters. This metro-network extension south of the Danish capital (Sydhavn or M4) will be connected to the main ring line (Cityringen).
Hochtief and VINCI have brought together their skill sets in design, project management, and underground works to build this 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.
Hochtief and VINCI have a longstanding tradition of collaboration, including on metro projects (such as the one in Athens, for example). More recently, the two groups have joined forces on projects in Greece and in other countries outside Europe.
In Copenhagen Hochtief, in a joint venture, is currently executing the Metro Cityringen Branch-off to Nordhavn tunnel project.
In the capital of Denmark, the company also built an approximately four-kilometer-long district heating tunnel. Hochtief has already been successfully operating on the Scandinavian infrastructure market for many years. For instance, the company was responsible for building the Eastern Bridge over the Great Belt.
Another milestone is the construction of the Øresund Bridge between Copenhagen and Malmö, in which Hochtief also had a significant participation. ■
