Drilling for Europe's deepest parking garage


Leiden is not only the oldest university town in the Netherlands, but is also the birthplace of Rembrandt, the world-famous painter. Europe's deepest parking garage, with a total depth of 22 meters, is being constructed directly in the center of the picturesque old town.
BAUER Funderingstechniek B.V., the Dutch subsidiary of BAUER Spezialtiefbau GmbH, constructed an underwater concrete base with 585 GEWI piles. Drilling depths of up to 55 meters were reached with three anchor drilling rigs manufactured by KLEMM Bohrtechnik GmbH (2 x type KR 806-2B and 1x type KR 806-2DB) which were used from pontoons. Each drilling rig was equipped with hydraulic drifter and linear rod handling magazine.
The underground parking garage with its 525 parking spaces will be completely finished by 2017.
