The proposed steel bridge has an indefinite life. The initial cost of the bridge is $3,750,000 and annual maintenance costs are estimated to be $25,000. The bridge deck will be resurfaced every 10 years for $900,000 and anti-corrosion paint will be applied every 5 years for $250,000. If the interest rate is 8%, what is the EUAC?
C) Two alternatives have been proposed to construct a new road project to improve capacity and safety. The table below explains each alternative's costs: the initial construction costs, annual operating and maintenance costs after the first year, and resurface of road costs. Assume that the annual interest rate is 5%. Determine the present worth for each alternative, then choose the preferred alternative based on the economic criteria. by present worth Alternative The initial construction costs The annual operating and maintenance costs The resurface costs Service life (years) $4.000.000 $3.900 $850,000 (Every five years) 14 $3,800,000 $4,100 $800.000 (Every four years)
A reconstruction project of a 10-mile 4-lane concrete highway is proposed for next year. The initial cost per lane-mile is estimated to be $271000 with zero salvage value at the end of its service life of 30 years. The annual maintenance cost is expected to be $2710 per lane-mile. For a discount rate of 5.3%, compute the equivalent uniform annual cost.
