An excavation of 25,750 m3 (bm) is to be made for the foundation excavation of a building in 5 weeks assuming 6 workdays per week and 8 hours working time per day. It is expected that during excavation 5.0 workdays will be lost due to bad weather conditions. The excavation will be done in dry earth with an average depth of cut of 3,25 meter. Angle of swing is about 90°. Estimated working time in an hour is about 51 minutes. Determine the minimum size of the backhoe if only one backhoe will be used?

An excavation is to be made in a layer of clay which is 10 m thick and underlain by a sandstone formation. The water table is at the ground surface and the saturated unit weight of clay is 21 kN/m³. The water level in a piezometer installed in the sandstone rises 2.5 m above the ground surface. Draw a representative sketch of the problem and calculate the depth of excavation that can be reached without an upheave of the bottom of excavation.
Consider a 10 m deep excavation into a saturated clay with cohesive strength = 25 kPa and unit %3D weight = 19 kN/m. (a) Assuming that the bottom of the excavation is in firm ground, what is the estimate of Ka? (b) Assuming that the excavation is now underlain by a 5 m thick layer of softer soil with cohesive strength = 15 kPa and unit weight = 19 kN/m?, what is the estimated Ka?
