The following three mutually exclusive alternative proposals are being considered for flood proofing a factory building that is located in an area subject to occasional flooding by a nearby river. 1. Do nothing: Damage to the building in a moderate flood is $11,000 and in a severe flood it is $24,000. 2. Protect the building with a one-time initial expenditure of $20,000 so that the building can withstand moderate flooding without any damage and withstand severe flooding with only a $10,000 damage. 3. Protect the building with a one-time initial expenditure of $32,000 so that the building can withstand any flooding with no damage at all. In any year, there is a 19% probability of moderate flooding and a 9% probability of severe flooding. Using a MARR of 6% per year and a service life of 8 years, determine which of the three alternatives is the most economical. (a) Calculate EUAC values for each scenario (use negative numbers for costs) The expected EUAC for the "Do Nothing" alternative…

U.S. route 83 passes through the village of Burr Ridge, IL. The engineers of the Transportation Department have proposed constructing a new highway through existing farmland to bypass the city for use by through traffic. The new bypass would however entail an initial construction cost of $40 million and an average annual maintenance cost of $50,000. Assuming the overall user and non-user costs (associated with the positive and negative impacts) of the new project amount to $2 million per year, facility life of 25 years, and an annual nominal discount rate of 6% compounded quarterly, determine whether the project is worthwhile on the basis of agency costs, user costs, and non-user costs.
