Per Aarsleff achieved a contract to construct the building group Dokk 1 for the city of Aarhus in 2011. In addition they also constructed a new waterfront. The works comprised the installation of steel sheet pile retaining walls and concrete bearing piles, the demolition of existing quay walls, the lowering of the ground water and excavation.

The building group is approx. 100 x 100 m and 8 m deep with an automatic underground parking system delivered by the company Lödige (Germany) with a capacity of 1 000 cars. 

In total Aarsleff installed 3 700 tonnes of PU 32 with the sealing system Roxan® Plus and PU 12, as well as 42 000 running meters of concrete piles, and handled 250 000 m3 of sand and soil. 

For the installation of the sheet piles Per Aarsleff used a Hitachi 180 with a vibratory hammer ICE 1412 and an hydraulic impact hammer IHC S90 for the final driving. The sheet piles were driven into the Aarhus clay. The job safety was important since the site was located close to the port and to the railway. 

The 28 000 m2 building area hosts the library and the public service office of the City of Aarhus. 

Construction period: summer 2011 to 2017.
