Groundwater lowering and pump tests

At the end of 2019, Aarsleff executed a prolonged groundwater lowering for the construction of a 65,000 square metre office building at Kay Fiskers Square in Ørestad, Copenhagen. We carried out the work in a subcontract for Hoffmann A/S, whereas the client was the Norwegian Pension Fund, KLP. The groundwater lowering comprised 8 manually adjusted pumping wells and 4 back-up pumping wells in the same dimension to monitor the water level in the centre of the construction pit. Outside the construction site, the impact of the groundwater lowering on the local area was observed in 3 moni­toring wells.
