Additional drillings in connection with groundwater surveillance for the tunnel Ruckhalde, St. Gallen
In connection with the tunnelling work for the tunnel Ruckhalde in St. Gallen, which will be taken up by the Appenzeller Bahnen AG from winter 2014/2015 onwards, the groundwater level has to be lowered on a larger scale. Our office has been attending to the geological-hydrogeological aspects of this project since 2006 and now we are also able to supervise the surveillance measures for this lowering of the groundwater level.
