A construction company is choosing between two backhoes. Options A is a wheel-mounted version, with an initial cost of $65,000, an expected life of 6 years, and a salvage value of $5,000. Option B is a trackmounted version, with an initial cost of $85,000, a 9-year life, and a salvage value of $10,000. Both machines will achieve the same productivity. The interest rate is 9%.

a) What is the EUAC of option A ($/year)?

b) What is the EUAC of option B ($/year)?

c) If the interest rate is 12%, which option is preferred (A or B)?

Problem 2: Speeding in a construction zone

A group of Brigham Young University—Idaho students collected data on the speed of vehicles traveling through a construction zone on a state highway, where the speed was 25 mph. The recorded speed (in mph) of 14 randomly selected vehicles is given below:

20,24,27,28,29,30,32,33,34,36,38,39,40,40

• Assuming speeds are approximately normally distributed, construct a 95% confidence interval for the true mean speed of drivers in this construction zone. Interpret the interval.

• Construct a 99% confidence interval for the true mean speed of drivers in this construction zone. Interpret the interval.

• Compare the widths of the 95% and 99% confidence intervals.

• What conclusions do you draw about the speeds people drive in this construction zone?

Conduct research on one of the first built tombs in the world. The selected tomb should have a superstructure. Specifically, focus on the, Evidential, Historical, Aesthetic and Communal Values of the tombs. In other words, determine the specific futures of a tomb in relation to their evidential, historical, aesthetic, and communal values

Architect, architectural features, construction year and duration, construction materials, construction type, structural features, construction purpose and the features that make it different and significant and the importance of the construction for the society should be included and explained under the headings of Evidential, Historical, Aesthetic and Communal Values in the report. You should illustrate your explanations with photographs which should be referred in your report.

Sustainable development has become an important part of the lives and aspects of enterprise operations globally and locally. There is a global trend to enhance sustainable practices in all sectors and most especially the construction sectors. In fact, the construction industry is responsible worldwide for the usage of 40% of total energy production, 40% of raw materials and 25% of timber; the use of 16% of water, generates 30- 40% of solid waste and 35-40% of CO2 emissions. The government of Malaysia has introduced the Construction Industry Transformation Programme (CITP) to transform the construction industry from 2016 to 2020. It aims to transform the construction industry through four strategic thrusts: Quality, Safety and Professionalism, Environmental Sustainability, Productivity and Internationalisation

please explain

Washington County’s Board of Representatives is considering the construction of a longer runway at the county airport. Currently, the airport can handle only private aircraft and small commuter jets. A new, long runway would enable the airport to handle the midsize jets used on many domestic flights. Data pertinent to the board’s decision appear below.

In addition to the preceding data, two other facts are relevant to the decision. First, a longer runway will require a new snowplow, which will cost $165,000. The old snowplow could be sold now for $16,500. The new, larger plow will cost $14,000 more in annual operating costs. Second, the County Board of Representatives believes that the proposed long runway, and the major jet service it will bring to the county, will increase economic activity in the community. The board projects that the increased economic activity will result in $72,000 per year in additional tax revenue for the county.

In analyzing the runway proposal, the board has decided to use a 10-year time horizon. The county’s hurdle rate for capital projects is 11 percent.

Use Appendix A for your reference. (Use appropriate factor(s) from the tables provided.)

Required:

1. 1. Prepare a net-present-value analysis of the proposed long runway.

The Utah Mining Corporation is set to open a gold mine near Provo, Utah. According to the treasurer, Monty Goldstein, “This is a golden opportunity.” The mine will cost $2,600,000 to open and will have an economic life of 11 years. It will generate a cash inflow of $365,000 at the end of the first year, and the cash inflows are projected to grow at 8 percent per year for the next 10 years. After 11 years, the mine will be abandoned. Abandonment costs will be $420,000 at the end of Year 11.
