Please Solve the costs for company A and company B
Construction of an embankment needs 400,000 yd3 of fill. The fill should be compacted to at least 88% of the standard Proctor maximum dry density obtained in the lab, which is gammad_d,max = 128 pcf, but the contractor plans to exceed that by 2% to ensure passing quality control. The fill may be obtained from two companies (A and B) with the following profiles. Company A Distance from borrow pit to embankment: 25 miles Cost of haul ($/yd3-mile): 0.50 Cost of fill material ($/yd3): 1.50 Borrow soil moisture content: 16% Specific gravity of solids: 2.70 Degree of saturation: 70% Company B Distance from borrow pit to embankment: 30 miles Cost of haul ($/yd3-mile): 0.40 Cost of fill material ($/yd3): 1.40 Borrow soil moisture content: 18% Specific gravity of solids: 2.65 Degree of saturation: 58% The total cost of haulage by company A (million $) The total cost of haulage by company B (million $) The relative compaction, CR, should account for the contractor's plan to exceed the minimum CR stipulated in the contract. For the volume Vs needed for the fill, V = (1+e) Vs needs to be excavated and hauled, charging the project at its own rate.
