BUILDING A NEW NEIGHBORHOOD IN STOCKHOLM
In the first half of the 20th century, the Norra Djurgårdsstaden district in Stockholm, Sweden, was a busy industrial center and port area with an oil port, a coal port, a free port, and even a seaplane base. Today, it is one of the largest urban development areas in Europe.
The Norra Djurgårdsstaden development project was kicked off in the early 2010s. The first 700 apartments were completed in 2012, and construction work is expected to continue well into the 2030s.
The overall plan includes construction work in five sub-areas in the district. One of them is Project Saltkajen in Södra Värtahamnen, where a new pier with an associated bridge will be constructed, and the existing quay will be rebuilt. The city of Stockholm signed the contract, worth SEK 610 million, with Skanska.
Foundation work for the project includes extensive pipe piling and sheet piling in demanding conditions: more than 500 SSAB RD pipe piles (711 mm and 508 mm) will be drilled and connected by welded interlocking sections, creating a continuous retaining wall against horizontal and vertical loads.
Skanska chose the Robit Steel Fist (SF) casing system to drill the RD piles. SF is a solid choice for all DTH applications where the casing is left in the ground. Skanska has successfully used it in previous projects, such as the Slussen reconstruction in Stockholm.
As construction continues, Norra Djurgårdsstaden is slowly transforming into a modern, environmentally friendly, sustainably built district with 12,000 homes and an estimated 35,000 new jobs. Värtahamnen will be home to some 5,000 people, and 20,000 will work there. With new walkways, shops, restaurants and nightlife, it will also be an inviting entry point for international visitors arriving in Stockholm by boat.
