Calculate the tender rate per bank cubic meter for an excavation of a trench given:• Hire cost = R800 per hour, including owning costs• Fuel Consumption = 4 l/h of Diesel fuel at R15/h• Scoop capacity is 35 banks m3/h• Operating factor = 0.8• Dimensions of trench: 10m x 3m• Operator earns R40.41/h• Head office overheads = 30%• Site overheads = 20%• Profit margin factor = 0.045• Contractor has perceived no risk on this operation
(c) Giver the end area of cut and fill of soil as in Table Q4(c). If the material bulks after excavation about 10% and shrink 12%. Given, distance between chainage is 100 m. Draw the mass haul diagram and estimate how much excess cut or fill is required.
What do you mean by Keep the horizontal width of the excavation to make sure that work activity would not vibrate the soil while workers are in the trench? Cite some examples as well.
determine the volume of fill and cut.
You are excavating a location for the vault shown below.The top of the walls shown are 1 foot below grade. Allslopes of the excavation are 1 to 3/4 per OSHA regulations(assuming type A soil) to a toe 1 foot outside the base of thewalls. The walls sit on a slab 1 foot in depth. Draw a sketchof the volume to be excavated, break it into components,and calculate the volume. The material from the excavationis to be used in a compacted fill. The front-end loader excavatingthe vault has an output of 200 bank cubic yards ofcommon earth per hour. It loads a fleet of four trucks(capacity 18 loose cubic yards each) that haul the earth to afill where it is compacted with a shrinkage factor of 10%.Each truck has a total cycle time of 15 minutes, assuming itdoes not have to wait in line to be loaded. The earth has aswell factor of 20%. How many hours will it take to excavateand haul the material to the fill?a. What is the production of this system in cubic yards perhour, assuming the trucks carry 35…
