Step by step
Solved in 2 steps
- if you need to build a road of length 1Km and width 16ft in three layers. calculate the total cost of materials , labor and equipments used to make this road in 10 days. The rates are givenRailroads have abandoned a significant number of miles of track (over 260,000 miles) since 1916. Why has this trend developed? Will it continue into the future? Why or why not?A secondary road in a developing country, 30 miles long, is to be improved by surface treating the gravel surface without any change in length. The cost of the improvement is estimated at $150,000 per mile. A present annual transport cost for all traffic on the existing road (vehicle operating cost, maintenance cost, etc.) is estimated at $205,000 per mile. After improvement, this is expected to reduce to $170,000 per mile per annum. Reconstruction takes place in two years with equal expenditures in each year. Assume that in the second year of construction, transport cost on the improved road is equivalent to present costs in half the length and new transport cost on the other half. Would you undertake the project? (The minimum attractive rate of return (MARR) is 8.5% and the project life is 20 years after reconstruction.) Resealing would be required 10 years after reconstruction at a cost of $55,000 per mile. Use the net present worth method
