A bridge design firm is performing an economic analysis of two mutually exclusive designs for a highway overpass. The steel girder option has an initial cost of $2.22 million, and the concrete option has an initial cost of $2.31 million. Every 25 years, the steel bridge must be painted at a cost of $430,000, and all other maintenance costs are the same for both options. The steel bridge is expected to last 50 years, and concrete bridge is expected to last 75 years. Both are assumed to be identically replaced indefinitely. Based on the shortest acceptable analysis period for each option, determine the equivalent uniform annual cost (EUAC) for the best option using an interest rate of 7%. Express your answer in $ to the nearest $1,000.

Beaver, a city in the United States, is attempting to attract a professional soccer team. Beaver is planning to build a new stadium that will cost $240 million. The annual upkeep is expected to amount to $830,000. The turf will have to be replaced every 9 years at a cost of $860,000. Painting every 8 years will cost $88,000. If the city expects to maintain the facility indefinitely, what is the estimated capitalized cost at i = 9% per year? The estimated capitalized cost is $
Two traffic signal systems are being considered for an intersection. One system costs $31,000 for installation and has an efficiency rating of 80%, requires 26 kW power (output), incurs a user cost of $0.23 per vehicle, and has a life of 9 years. A second system costs $47,000 to install, has an efficiency rating of 87%, requires 34 kW power (output), has a user cost of $0.19 per vehicle, and has a life of 17 years. Annual maintenance costs are $75 and $95, respectively. MARR = 8% per year. How many vehicles must use the intersection to justify the second system when electricity costs $0.09/kWh? Assume salvage value for each system equals zero. Project the difference in the user cost as savings for the second system. There are approximately 8,760 hours/year. Click the icon to view the interest and annuity table for discrete compounding when the MARR is 8% per year. At least 108000 vehicles per day must use the intersection to justify the second system.

Waller County is planning to construct a Dam some tens of miles away from the Hempstead Recreation center to facilitate fishing in the El Manny River Basin and Power Generation. The first cost for the Dam will amount to $6,500,000. Annual maintenance and repairs will amount to $24,000 for the first four years, to $28,000 for each year in the next eight years, and to $32,000 per year for the next four years. At the end of the 16th year, $25,000 is estimated to be deposited into Waller county account as tax credits earned for its environmental compliance in the construction and operation of the Dam. In addition a major overhaul costing $650,000 will be required at the end of the seventh year. Use an interest rate of 10% and : a) Determine the engineering economy symbols and their value for each option. b) Construct the cash flow diagram c) Calculate the Capital Recovery for the project
Question 4 Consider a proposal to enhance production of tortillas en a taqueria. The new machine is estimated to cost $30 million and will incur an additional $1 million per year in maintenance costs. The machine will produce annual savings of $6 million each year. The Minimum acceptable rate of return (MARR) is 11% per year, and the study period is five years at which time the machine will be obsolete (worthless). What is the maximum (minimum) value of maintenance cost that reverse your decision? Write 4 decimals
A bridge design firm is performing an economic analysis of two mutually exclusive designs for a highway overpass. The steel girder option has an initial cost of $2.26 million, and the concrete option has an initial cost of $2.33 million. Every 25 years, the steel bridge must be painted at a cost of $560,000, and all other maintenance costs are the same for both options. The steel bridge is expected to last 50 years, and concrete bridge is expected to last 75 years. Based on the shortest acceptable analysis period, determine the present worth of costs for the best option using an interest rate of 7%. Express your answer in $ to the nearest $10,000.
