Tenders Are Invited For Construction Work – Köhlbrand Crossing - Subsoil Investigation East Land Lot 2

Construction Work – Köhlbrand Crossing - Subsoil Investigation East Land Lot 2. As Part Of The General Subsoil Investigation, 35 Boreholes And 43 Pressure Soundings Are Planned For The Köhlbrand Crossing In The Roßbrücke To Travehafen Area (Tp03e And Tp03hs). As Part Of The General Subsoil Investigation, 108 Boreholes And 109 Pressure Soundings Are Planned For The Kno In The Roßhafen To Travehafen Area (Tp01e And Tp04). For The Dismantling Of The Old Kbb In The Roßhafen To Travehafen Area, 10 Boreholes And 10 Pressure Soundings Are Planned (Tp05). To Investigate The Pile Test Loads In The Roßhafen To Travehafen Area, 9 Boreholes And 9 Pressure Soundings Are Planned (Tp01, Tp03e And Tp04). So Far, The Following Subsoil Explorations Are Planned: - 162 Dry Boreholes (B) To Expected Drilling Depths Of Between 25 M And 90 M. Depending On The Drilling Results, Whereby 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. - 171 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.
