Two alternatives are under consideration for maintenance of a bridge. Select the mostcost-effective alternative using present worth analysis. Assume an interest rate of10% per year and a design life of 50 years for each alternative.Alternative A consists of annual maintenance costs of $5,000 per year for the designlife except for:Year 20, in which bridge deck repairs will cost $20,000Year 30, in which a deck overlay and structural repairs will cost $105,000Alternative B consists of annual maintenance costs of $3,000 per year for the designlife except for:Year 20, in which bridge deck repairs will cost $35,000Year 30, in which a deck overlay and structural repairs will cost $85,000
The proposed steel bridge has an indefinite life. The initial cost of the bridge is $3,750,000 and annual maintenance costs are estimated to be $25,000. The bridge deck will be resurfaced every 10 years for $900,000 and anti-corrosion paint will be applied every 5 years for $250,000. If the interest rate is 8%, what is the EUAC?
The London Millennium Bridge project cost about GBP18.2 million to build (about GBP 2.2 million over budget). The bridge was opened on 10th June 2000 and closed 3 days later due to defects. An additional GBP 5million was needed for the modification & repair works and finally re-opened in February 2002. From the project management point of view, use the triple constraint to gauge the project's success (construct & state the factors in the triple constraint. Is the project a success? (Include justification based on your understanding)

national motors must build a bridge to access land for its manufacturing plant expansion. If made of normal steel, the bridge would initially cost $38,000. and it should last 13 years. Maintenance (cleaning and painting) will cost $1900 per year. If a more corrosion-resistant steel were used, the annual maintenance cost would be only $180 per year (with the same life). if the firm's cost of money is 13%, what is the maximum amount that should be spend on the corrosion-resistand bridge?
1. A project your firm is considering for implementation has these estimated costs and revenues: an investment cost of $50,000; maintenance costs that start at $5,000 at the end of year (EOY) 1 and increase by $1,000 for each of the next 4 years, and then remain constant for the following 5 years; savings of $20,000 per year (EOY 1-10); and finally a resale value of $35,000 at the EOY 10. If the project has a 10-year life and the firm's MARR is 10% per year, what is the present worth of the project? Is it a sound investment opportunity? 2. A toll bridge across the Mississippi River is being considered as a replacement for the current 1-40 bridge linking Tennessee to Arkansas. Because this bridge, if approved, will become a part of the U.S. Interstate Highway system, the B-C ratio method must be applied in the evaluation. Investment costs of the structure are estimated to be $17,500,000 and $325,000 per year in operating and maintenance costs are anticipated. In addition, the bridge…
Please solve this question. There are two alternatives for a construction firm to purchase a road roller which will be used for the construction of a highway section. The cash flow details of the alternatives are as follows; Alternative-1: Initial purchase cost = Rs.1,500,000, Annual operating cost = Rs.35,000 starting from the end of year “2” (negligible in the first year) till the end of useful life, Annual revenue to be generated = Rs.340,000 for first 4 years and then Rs.320,000 afterwards till the end of useful life, Expected salvage value = Rs.430,000, Useful life = 8 years. Alternative-2: Initial purchase cost = Rs.1,800,000, Annual operating cost = Rs.25,000, Annual revenue to be generated = Rs.365,000, Expected salvage value = Rs.550,000, Useful life = 8 years. Evaluate these alternatives & find out the most economical alternative on the basis of equivalent future worth at the interest rate of 9.5% per year.
Your employer asks you to design a bridge that will not exceed $1 million to build. After doing a study you determine the following: An ideal bridge can be built for $1.5 million. Given the design constraints, a bridge built for $1 million will collapse in a moderate earthquake. Your employer says; “if we don’t build the bridge for $1 million, then we are going to have to fire half of the staff, including you.” He further asks you to go ahead with the next stage of the project. From your own point of view with Engineering ethics being the focal point; DISCUSS what you will do?
The initial investment for constructing a median and guardrails for a prestressed concrete bridge is $1000000. Maintaining these facilities is expected to cost $2000 annually for the first five years of service and $10000 for the next five years of service. It is expected that these facilities will be rehabilitated at the end of the tenth year at a cost of $60000, after which the maintenance costs are expected to decrease to $6000 per year. What is equivalent uniform annual cost over a 15 -year period of service if the interest rate is 6% per year?
Project Z has a current budget of $20 million. The project is working on a 20-month schedule. After month 6, the following performance data is available: Actual Cost (AC) = $6.5 million; Planned Value (PV) = $6.8 million; Earned Value = $7.1 million. What would be the Estimate at Completion, assuming that current cost performance will continue for the rest of the project?

3. 8.5 Two different routes are under consideration for a new interstate highway: Table P8.5 The "long" route Transmountain shortcut Length of Highway 22 miles First Cost $21 million 10 miles 10 miles $45 million Annual Upkeep $140,000 $165.000 Table P8.5 Full Alternative Text For either route, the volume of traffic will be 400,000 cars per year. These cars are assumed to operate at $0.25 per mile. Assume a 40-year life for each road and an interest rate of 10%. Determine which route should be selected.
