Question
Sketch the soil profile of a project site where the two boreholes (BH) shown below were sunk. Provide the average values of the following soil properties and the soil classification of each layer. needed in foundation design: Water content, specific gravity, and unit weight (use approximated values) are required in foundation design. LL, PL, and average SPTN value (based on SPTN values) (or shear strength, if any). Also, make a note the level of the groundwater The distance between the two boreholes was 20 meters.
