Metroselskabet has awarded a EUR $460-million Design-Build contract for Sydhavn Metro Line (Line 4) in Copenhagen, Denmark, 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.
This Design-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 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).
For the first time in Denmark, 3-D modeling will be used extensively as early as the bid-submission phase by the consortium.
