Tenders Are Invited For Construction Work – Köhlbrand Crossing - Subsoil Investigation On The West Side, Lot 1

Construction Work – Köhlbrand Crossing - Subsoil Investigation On The West Side, Lot 1. As Part Of The General Subsoil Investigation, 11 Boreholes And 14 Pressure Soundings Are Planned For The Köhlbrand Crossing In The Rugenberger Hafen Area, Waltershof Crossing (Tp03w And Tp03hs). 96 Boreholes And 95 Pressure Soundings Are Planned For The Knw In The Waltershof Area (Tp01w And Tp02). For The Dismantling Of The Old Kbb In The Waltershof Area And The Rugenberger Lock, 7 Drillings And 7 Pressure Soundings Are Planned (Tp05). In The Pylon West Land Reclamation Area, 3 Boreholes And 3 Pressure Soundings Are Planned (Tp03lg). Three Boreholes And Three Pressure Soundings Are Planned To Explore The Pile Test Load In The Area Of ​​Waltershof, Rugenberger Schleuse And Pylon West. Some Of These Outcrops Are Also Used To Explore Be Areas (Tp03w). So Far, The Following Subsoil Explorations Are Planned: - 120 Dry Boreholes (B) With Expected Drilling Depths Between 20 M And 80 M. Depending On The Drilling Results, Where The Depth Of The Existing Mica Clay Is Crucial, In Individual Cases It May Also Be Necessary To Extend The Borehole Beyond The Planned Drilling Depth. - 122 Peak Pressure Probes (Cpt) Up To The Devices Full Capacity. The Location Of The Planned Starting Points For The Subsoil Exposures Can Be Found In The Site Plans In The Attached Appendix 1. Starting Points That Deviate From The Drilling Plans May Arise Due To Local Conditions, Official Requirements, Technical Feasibility And Explosive Ordnance Issues. As Part Of The Dry Drilling, Groundwater Measuring Points (Gwm) (4.0 Inch Pvc) Are Being Expanded At Selected Locations. The Gwm Will Later Be Used To Continuously Record The Groundwater Levels In The Entire Study Area. The Coordinates Of The Planned Exposures And The Required Exposure Depths Can Be Found In Appendix 2. Drilling Monitoring (Bü) Is Carried Out By The Kempfert Geotechnik And Baugrund Stralsund Offices.
