USE OF ANY REFERENCE MATERIAL WELCOME. Question 1: A consulting engineer has been engaged to advise a town how best to proceed with the construction of a 20,000 km3 water supply reservoir. Since only 12,000 km3 of storage will be required for the next 25 years, an alternative to building the full capacity now is to build the reservoir in two stages. Initially, the reservoir could be built with 12,000 km3 of capacity and then, after 25 years, the additional of 8,000 km3 of capacity could be added by increasing the height of the reservoir. Estimated costs are as follows: Construction cost Annual maintenance cost Build in two stages – First stage: 12,000 km3 – Second stage: additional 8,000 km3 of capacity, additional construction cost and maintenance cost $14,200,000 $12,600,000 $75,000 $25,000 Build full capacity now $22,400,000 $100,000 If the interest rate is at 6%, which construction plan is preferred? Question 2: An engineer has received two bids for an elevator to be installed in a new building. The bids, plus his evaluation of the elevators, are as follows: Engineer’s evaluation Service life (year) Annual operating cost Salvage value Westinghouse $45,000 10 $2,700 $3,000 Otis $54,000 15 $2,850 $4,500 If the interest rate is 10%, using the present worth method, which bid should be accepted?
