ABS 38 Nacherkundungsleistungen Entwässerungsplanung, PA03 Abschnitt Ost

TENDER DESCRIPTION

To specify the drainage planning in the ABS 38 project, East section (PA03), it is necessary to determine the infiltration capacity of the subsoil precisely. The tendered works are intended to determine the infiltration parameters in situ. This creates the conditions for more accurate planning and reduces risks during construction execution. The works in question are as follows: Set up construction site, surveying and measuring the investigation points approx. 1,200 units including drilling display and geocoordinates, trial pits approx. 1,200 units, construct boreholes for drawdown tests approx. 1,600 m, fill boreholes approx. 1,600 m, create investigation pits approx. 495 units at various depths of 1.25 to 5 m, create small investigation pits approx. 470 units at depths of 0.5 to 1.25 m, infiltration tests approx. 965 units including documentation/recording for determining the infiltration capacity of the subsoil in accordance with DWA A 138-1, open end test approx. 320 units including documentation/recording for determining the infiltration capacity of the subsoil in accordance with DIN 19682-8
