The Citytunnel is a transport solution that will connect the railway line to the north of Malmö with the railway line to Trelleborg, Ystad and Copenhagen.
NCC’s assignments for the Citytunnel include Malmö C nedre, the new station section at central station. Part of the assignment is a platform that connects the existing railway station to an underground station section directly joined to Malmö C station and a new switchbox, where the two TBM tunnels meet.
The entire project will be constructed in an open pit with temporary supporting structures in the form of sheet piles and slotted walls. The work site is 900 meters long in total. Work is divided into phases, since traffic must always be able to pass in a north-south direction.
Approximately 15,000 tons of reinforcement and 120,000 cubic meters of concrete will be used in the permanent structures. To ensure that the work is as efficient as possible, about 80 percent of the reinforcing cages are prefabricated indoors and subsequently lifted into place in the pit, where the final work is performed.
