r project team has been tasked to complete a project to build a new bridge to replace an old one on a road at a point that crosses a small river in a rural community. The old bridge to be replaced is on a single access road to the community and was recently damaged by heavy vehicles crossing it for a construction work in the village. The old bridge is still in use but has failed in the mid-section and can collapse in anytime – the project is therefore urgent from a safety point of view. The bridge is used by both vehicles and pedestrians at all times of the year. The community had petitioned the local council for support in replacing the old bridge but the response had been slow.

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 $12,000 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 20% probability of moderate flooding and a 10% probability of severe flooding. Using a MARR of 12% 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"…
The city of Papagos, Arizona, had a deteriorating bridge in need of repair on a prominent public roadway. The city posted notices seeking proposals for an artistic bridge design and reconstruction. Davidson Masonry, LLC, which was owned and managed by Carl Davidson and his wife, Marilyn Rowe, decided to submit a bid to create a decorative concrete structure that incorporated artistic metalwork. They contacted Shana Lafayette, a local sculptor who specialized in large-scale metal creations, to help them design the bridge. The city selected their bridge design and awarded them the contract for a commission of $184,000.Davidson Masonry and Lafayette then entered into an agreement to work together on the bridge project. Davidson Masonry agreed to install and pay for concrete and structural work, and Lafayette agreed to install the metalwork at her expense. They agreed that overall profits would be split, with 25 percent going to Lafayette and 75 percent going to Davidson Masonry.…
In the aftermath of Hurricane Thelma, the U.S. Army Corps of Engineers is considering two alternative approaches to protect a freshwater wetland from the encroaching seawater during high tides. The first alternative, the construction of a 5-mile long, 20-foot-high levee, would have an investment cost of $25,000,000 with annual upkeep costs estimated at$725,000. A new roadway along the top of the levee would provide two major benefits: (1) improved recreational access for fishermen and (2) reduction of the driving distance between the towns at opposite ends of the proposed levee by 11 miles. The annual benefit for the levee has been estimated at $1,500,000. The second alternative, a channel-dredging operation, would have an investment cost of $15,000,000. The annual cost of maintaining the channel is estimated at $375,000. There are no documented benefits for the channel-dredging project. Using a MARR of 8% and assuming a 25-year life for either alternative, apply the incremental B–C…
Metal Recycling and Salvage receives the opportunity to salvage scrap metal and other materials from an old industrial site. The current owners of the site will sign over the site to Enviro at no cost. Enviro intends to extract scrap metal at the site for 24 months and then will clean up the site, return the land to useable condition, and sell it to a developer. Projected costs associated with the project follow: Read the requirements2. Requirement 1. Assuming that Enviro expects to salvage 70,000tons of metal from the site, what is the total project life cycle cost? Total Life-Cycle Costs Variable costs: Metal extraction and processing Fixed costs: Metal extraction and processing Rent on temporary buildings Administration Clean-up Land restoration Selling land Total life-cycle cost Requirement 2. Suppose Enviro can sell the metal for $110 per ton and wants to earn a…
A local hospital has the following replacement decision problem:Old machine: The hospital purchased a digital image-processing machinethree years ago at a cost of $50,000. The machine had an expected life ofeight years at the time of purchase and an expected salvage value of $8,000at the end of the eight years. However, the old machine has been slow athandling the increased business volume, so management is consideringreplacing it. The old machine can be sold today for $12,000. New machine: A new machine can be purchased for $80,000, includinginstallation costs. Over its five-year life, the new machine will reduce cashoperating expenses by $30,000 per year. Sales are not expected to change.At the end of its useful life, the new machine is estimated to be worthless.The hospital's interest rate for project justification is known to be 12%. The hospital does not expect a better machine (other than the current challenger) to be available for the next five years. Assume that the economic…
Project: The streets and roads maintained by the government have not had an adequate maintenance program. The Public Works Department’s Civil Engineers have recommended the establishment of a dedicated team for the rapid and efficient accomplishment of the repair of potholes and other paving failures. The accomplishment of this recommendation is expected to require the services of a full-time, dedicated crew of four (4) field personnel: one (1) Crew Foreman and three (3) Maintenance Workers. The efforts of this group will be the constant execution of a job-order report from the Public Works Department’s current Road Inventory computer software’s Repair Report List. They will accomplish their scheduled work using an automated asphalt patching system for the repair of potholes in major roadways that will be purchased for this purpose. Purchase price estimated @ $175,000. The purchase price includes training of three (3) individuals in the operation and maintenance of the equipment. The…
A steel pedestrian overpass must either be reinforced or replaced. Reinforcement would cost $25,000 and would make the overpass adequate for an additional 6 years of service. If the overpass is torn down now, the scrap value of the steel would exceed the removal cost by $15,000. If it is reinforced, it is estimated that its net salvage (market) value would be $18,000 at the time it is retired from service. A new pre- stressed concrete overpass would cost $140,000 and would meet the foreseeable requirements of the next 40 years. Such a design would have no scrap value or market value. It is estimated that the annual expenses of the reinforce overpass would exceed those of the concrete overpass by $3,200. Assume that money costs 8% per year, what would you recommend?
A project is being considered by the Tennessee Department of Transportation to replace an aging bridge across the Cumberland River on a state highway. The existing two-lane bridge is expensive to maintain and creates a traffic bottleneck because the state highway is four lanes wide on either side of the bridge. The new bridge can be constructed at a cost of $300,000, and estimated annual maintenance costs are $10,000. The existing bridge has annual maintenance costs of $18,500. The annual benefit of the new four-lane bridge to motorists, due to the removal of the traffic bottleneck, has been estimated to be $25,000. Conduct a B-C analysis, using a MARR of 8% and a study period of 25 years, to determine whether the new bridge should be constructed.

Jerry Smith’s residential air conditioning (AC) system has not been able to keep his house cool enough in 90◦F weather. He called his local AC maintenance person, who discovered a leak in the evaporator. The cost to recharge the AC unit is $40 for gas and $45 for labor, but the leak will continue and perhaps grow worse. The AC person cautioned that this service would have to be repeated each year unless the evaporator is replaced. A new evaporator would run about $800–$850. Jerry reasons that fixing the leak in the evaporator on an annual basis is the way to go. “After all, it will take 10 years of leak repairs to equal the evaporator’s replacement cost.” Comment on Jerry’s logic. What would you do?
The town of Melville needs to obtain an additional supply of water from a nearby river. They have been offered two options: diverting water at a point 8 miles upstream and allowing gravity to move the water to the town (the "gravity" plan), or diverting water at a point much closer to the town and using pumps to move the water to the town (the "pumping" plan). The pumping plan would be built in two stages, with half of its capacity installed initially and the other half installed ten years later. For both options, the town wants to use a 40-year life, 10% interest, and no salvage value. The projected costs are in the table below: Initial Cost Additional investment at the end of the 10th year Annual Operation and Maintenance, excluding Power Annual Power Cost Gravity $2,800,000 None $10,000 $25,000 $75,000 Use an Annual Worth analysis to determine the most economical plan for the town.
