After our company did geotechnical and contamination surveys for a number of construction undertakings on the company premises of the ThyssenKrupp Presta AG in Eschen, a geotechnical analysis of the whole area of the premises will be carried out.
A cooperation consisting of the city of Gossau, the technical Services of Gossau, the Municipal Utilities of St. Gallen (sgsw) as well as the Canton of St. Gallen have decided to commission GBB with an extensive groundwater model calculation in order to protect and plan a sustainable cultivation of the extensively used groundwater volume between Gossau and St.Gallen. The models goal is to better estimate the future impact on the groundwater arising from additional usage of the water and the construction of new buildings in that zone. Moreover, it is useful in order to design possible future zones for the use of geothermal energy from the groundwater.
A new building is planned to be constructed close to the Private Clinic for Psychiatry and Psychotherapy on the so called area “Rössli” at Littenheid. In order to be able to construct the new building, three existing buildings and one gasoline station have to be dismantled. Due to the year of construction and the journalization in the cadastral land register of the contaminated location we expect some contaminants and a necessary examination of the contaminated site.
In this context, Senn Resources AG has assigned us to capture and document building contaminants. Thereby, contaminated materials containing Asbest, PCB- and PAK were identified directly on site or probes taken from suspicious building components and analysed in the laboratory.
