Attractive meeting spot
Once completed, the new Slussen will cater to fewer cars, while offering enhanced solutions for pedestrians, cyclists and public transport. Stockholm City is also seeking to turn it into an attractive meeting spot, complete with a city park and new market squares. Last but not least, the redevelopment project will secure clean drinking water from Lake Mälaren for two million habitants.
The project started in 2016 and is well on its way. So far, SSAB has delivered 117,000 meters of piles, corresponding to 10,700 tons of steel, to Skanska and Slussen since the project began.
RD® piles from SSAB play a crucial part
Marzena Burzec-Burzynska explains that SSAB’s RD® pile retaining walls have an especially crucial part to play in this challenging project.
“RD walls are used instead of sheet pile driving when the ground conditions demand it or when we want to reduce the impact on the area, because drilling causes fewer vibrations,” she explains, adding: “Since we are working so close to Stockholm’s Old Town and subway system, choosing this method was of vital importance.”
The area around Slussen has a complex geology, with depths of up to 70 meters to bedrock. It is made up of various layers of the Stockholm Ridge and many centuries of filling material. As a result, different types of piles are being used at Slussen depending on ground conditions.
