The Niederhafen in Hamburg, Germany features the city’s most famous harbour promenade that connects the St. Pauli Landing Bridges with the historical old warehouse district.
At this location, the existing flood control structure built between 1964 and 1968 was renewed in two sections over a length of approx. 625 m. The new structure is 1.40 to 1.70 m higher than the existing flood control structure.
First, the existing promenade was demolished and examined for Second World War warfare material. Afterwards, vibrated stone columns covered by geotextiles and steel piles were installed.
Installation of anchors from floating pontoons
Subsequently, Neidhardt Grundbau installed a total of 270 double corrosion protected anchors from floating pontoons to tie back the steel piling. The up to 35 m long anchors were supplied in segments of up to 18 m that were later joined together on the job site.
