Geotechnical Risks in a Deep Building Bit in The Hague's Old City Centre – Project Veenkade Case Study of the Restoration of an Old Canal and a New Underground Parking Garage

In The Hague, a 2 storey parking garage was built beneath a reinstated canal at the Veenkade with 160 parking places. The canal and the parking garage were installed at minimum 3 - 6 m distance from old houses with a shallow foundation by means of a 10 m deep building pit. A risk analysis was undertaken and major risks were identified, resulting in mitigating measures, e.g. compensation grouting in combination with very accurate monitoring. The structure was completed in 2014.
