Groundwater lowering, Copenhagen Central Station
Per Aarsleff A/S has executed groundwater lowering for the construction of a new transfer tunnel between Copenhagen Central Station and the new metro station, which is a part of the newly established Metro Cityring. The groundwater lowering comprised pumping wells, observation wells, monitoring wells, re-infiltration wells together with water treatment and installation of an alarm and emergency power system. Main parts of our work were carried out under the railway terrain, making track closures and logistic planning necessary with both night and weekend work.
