Additional work includes the foundation and construction of the building called Mälarterrassen, which is integrated into the city's facility. Planning and landscaping work are included. In addition, structural- and installation work, work with an art building and anchorages for a new pedestrian and bicycle bridge are also included. This means an extended contract period, partly due to archaeological excavations.
Skanska's assignment at Slussen started in 2015. The new agreement with additional work stipulates completion by the first of June 2025.
Skanska is already carrying out four contracts at Slussen. These include the lock itself with associated drainage channels, the Slussen bridge, low bridges, docks- and reinforcement work and associated work with the marketplace that is also being built. In addition, Skanska is carrying out structural work for the future bus garage.
