On behalf of the Communitiy of Schaan we have completed a ground sounding campaign on the development site of the Undera Forsts. The ground sounding campaign, which was carried out over an area of approximately 80 x 400 m, was completed by end of November, 2014. Within the survey area with its strongly alternating, geological layer composition we conducted core drillings down to 35 m below surface. The aim of that ground sounding campaign was the elaboration of an adequate geologic-geotechnical knowledge basis for the planned connecting road and for further building projects.
