A small bridge project is being evaluated at i=10%. Recommend an alternative based on the capitalized cost for each.

	Concrete	Steel
Initial cost	$5,000,000	$7,000,000
Annual maintenance cost	45,000	25,000
Major periodic maintenance cost	350,000	450,000
Major maintenance interval	10 years	15 years

You are a consulting engineer, and you have been asked to make an investment analysis on the construction and maintenance of a bridge. This time, instead of a letter, you are writing the executive summary page to a detailed report that determined all the cash flows given in the problem. You are limited to a single page (single spaced, multiple words). You do not make the calculations in the summary, simply discuss the approach, how you determined the solution to this investment decision, and what conclusions you reached. Invent your own firm and letterhead. The executive summary should have different sections (e.g., introduction, method/data, results/analysis, conclusion, etc.). Include the results as a table in the executive summary.

In lieu of actually attaching a full report, you will attach a summary of your calculations. This should summarize the calculations in enough detail so that someone else could reproduce your calculations. You do not need to reference this attachment in the executive summary.
