A public-private partnership has been formed between a city, county, and construction/management company to attract a professional athletic team to the area. Assume you are the engineer with the company and are assisting with the benefit/cost analysis. The primary options are to construct a domed arena (DA) or a conventional stadium (CS), one of which will definitely be built. The DA option will cost $200 million to construct, have a useful life of 50 years, and require M&O costs of $360,000 the first year, increasing by $10,000 per year thereafter. In 25 years, a remodeling expenditure of $4,800,000 is predicted.

The CS option will cost only $50 million to construct, have a useful life of 50 years, and require M&O costs of $175,000 the first year, increasing by $8000 per year. Periodic costs for repainting and resurfacing for the stadium are estimated at $100,000 every 10 years, except in year 50.

Revenue from DA is expected to be greater than that from CS by $10,900,000 the first year, with amounts increasing by $200,000 per year through year 15. Thereafter, the extra revenue from the dome is expected to remain constant at $13.7 million per year. Assuming that both structures will have a salvage value of $5 million, use an interest rate of 8% per year and a B/C analysis to determine which structure should be built. Solve by hand or spreadsheet, as instructed.
