Construction pit, piling and extensive groundwater lowering in Copenhagen

In 2018, Aarsleff entered into a contract for the con­struction of Danske Bank’s new headquarters at Bern­stoffsgade in Copenhagen. The contract comprised a 73,000-square-metre headquarters and an additional 40,000 square metres of parking facilities and technical installations. The 28,000-square-metre-large construction pit is unusual as the area is dominated by hard Copenhagen limestone from 11 metres below ground level. The chosen sheet pile installation method was a pre-bored trench in the dimension DN880 millimetres, which was stabilised with concrete bentonite, and the sheet pile profiles were subsequently installed by vibratory driving.
