Stockholm is growing fast. New Slussen will protect drinking water, create new places to meet, and allow more space for pedestrians, cyclists and public transport. All to meet the needs of today and tomorrow.

A solution for the future
The central waterfront area, Slussen, is – and will continue to be – an important traffic hub in Stockholm. Nevertheless, it will transform from a traffic junction to a meeting point. After years of usage, the obsolete structure now has to be demolished and rebuilt into a new and dynamic social meeting point with access to a variety of recreational activities. Likewise, more space will be created for pedestrians, cyclists and public transport.

Moreover, New Slussen will be adapted to the climate. It will eliminate the high risk of flooding currently threatening Stockholm, as well as allowing for an increase in sea level caused by future climate change. This will ensure access to drinking water and protect vulnerable areas and other important buildings and infrastructure.

Recycling is the key
As the current Slussen is demolished and reconstructed from scratch, large amounts of construction and demolition waste are generated. This is where Orbicon assists turnkey contractor Skanska and the City of Stockholm.

– For this project, it is our most important task to create smart and sustainable solutions for soil management. It is primarily necessary to reuse rock and soil masses within the project, then reuse the masses externally, and ultimately dispose them responsibly, Christian Lindmark, Senior Project Manager at Orbicon AB, said.

Therefore, Orbicon has developed a coherent strategy and action plan for how all masses will be tested and classified based on management of surplus masses and reuse.

The task of soil management will go on for six years and the project will generate about 200 000 m³ of soil, rocks and mud.  We aim to reuse as much of this as possible, and estimate that 80 000 m³ can be reused on site. Samples is taken down to 15 m. below grund with great care and consideration to constructions on the site.

The new structure is expected to be finished by 2025 with new buildings in the area being completed some years after.
