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 number of trucks for: If truck capacity=12 m3 (loose) and distance to dump area is 7.5 km. Vh=30 km/hr, Vr=60 km/hr, ts=2 min., td=3.5 min. Truck efficiency and dipper factor are same as those of the backhoes.

Show complete solution and answer in 4 decimal places The areas of the cross-section of an excavation are 3,897.23 sqm, 4,596.01 sqm, and 3, 786.30 sqm. The spacing of each cross-section from each other is 9.80m. a) Find the volume of Excavation by End Area Method. b) Find the Loose Volume of the soil excavated if it has a swell factor of 15.5%. C) A Dump Truck is rented Php 20,000 per day and can make 7 trips in a day. Find the cost of hauling if 5 Dump Trucks with a capacity of 10 cu. m. per trip is used.
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. Calculate the unit cost of excavation in TL/m3 if hourly costs are 300 TL for the selected backhoe and 100 TL for the trucks.
The soil condition in the field is as follows: c = 20 kN/m², = 20°, Y = 20 kN/m³ The maximum depth of unsupported excavation is m.
Do not round off answers in solving. Round off to two decimal place only to the final answer.

A 3 m deep excavation will be supported by a cantilever sheet pile. The foundation soil is dense sand, but it is assumed that the pile tip penetrates impermeable soil so hydrostatic pore pressure can be used. A surcharge of 10kPa is applied at the ground level. The water table is at the ground surface and dredge line as shown. Use Yw=10kN/m³ for your calculations. a) Using a factor of safety of 2.0 for Kp, check if D'=5m is safe or not (no need to iterate for other D'). b) Calculate the maximum bending moment. H=3.0m D.L. =+% D'=5m? 10 kPa G.L. Dense sand 3 Yt=20.0 kN/m³ c'=0 Ka=0.2 Kp=6.0 Impermeable soil
6.5 The sides of an excavation 3.0m deep in sand are to be supported by a cantilever sheet pile wall. The water table is 1.5 m below the bottom of the excavation. The sand has a saturated unit weight of 20 kN/m³, a unit weight above the water table of 17 kN/m³ and the characteristic value of o' is 36°. Using the traditional method, determine the required depth of embedment of the piling below the bottom of the excavation to give a factor of safety of 2.0 with respect to passive resistance. M
