NCC has signed an agreement with the Swedish Transport Administration for the construction of Central Station, which is a part of the West Link project in Gothenburg.
The contract involves building an underground commuter train station and about 2km of railway tunnelling.
The order is worth SEK4.7bn ($569.73m).
The award decision for the contract was communicated by NCC in May 2016. Since then, NCC and the Swedish Transport Administration worked under a new partnering model called Early Contractor Involvement (ECI), which entails close cooperation between the parties for project planning and cost optimisation.
The target cost now amounts to SEK4.7bn ($569.73m).
NCC Infrastructure division manager civil engineering Nils Bjelm said: “NCC is constructing two phases of the West Link project, which is a crucially important project for an expanding, attractive and sustainable Western Sweden.
“Our previous involvement with the City Tunnel in Malmo and the Stockholm City Line have given us valuable experience in terms of sustainable technical solutions and the use of leading-edge technology in civil engineering works,”
The contract involves construction of a new bridge over the E6 Highway in the east, a railway trough, a rock tunnel through Gullberget, a concrete tunnel in clay, the Station Centralen underground commuter train station north of Gothenburg Central Station and the remaining concrete tunnel to the west up to Gothenburg Opera House, a section of nearly 2km.
Production will begin immediately and preparatory work and tunnel construction will begin later in 2018.
The project is set to continue until 2026.
NCC Infrastructure regional manager civil engineering Per Kinell said: “Early entry into a project of this magnitude offers us an opportunity to create joint understanding of the challenges that a project of this type involves.
“We will be arranging a Nordic collaboration within NCC for this project and will be engaging the specialist know-how of Nordic large projects.”
