Feb. 1 Grimes and several others invested $600,000 cash in the business in exchange for 30,000 shares of capital stock. Feb. 10 The company purchased office facilities for $360,000, of which $120,000 was applicable to the land and $240,000 to the building. A cash payment of $72,000 was made and a note payable was issued for the balance of the purchase price. Feb. 16 Computer equipment was purchased from PCWorld for $14,400 cash. Feb. 18 Office furnishings were purchased from Hi-Way Furnishings at a cost of $10,800. A $1,200 cash payment was made at the time of purchase, and an agreement was made to pay the remaining balance in two equal installments due March 1 and April 1. Hi-Way Furnishings did not require that Heartland sign a promissory note. Feb. 22 Office supplies were purchased from Office World for $360 cash. Feb. 23 Heartland discovered that it paid too much for a computer printer purchased on February 16. The unit should have cost only $359, but Heartland was charged $395. PCWorld promised to refund the difference within seven days. Feb. 27 Mailed Hi-Way Furnishings the first installment due on the account payable for office furnishings purchased on February 18.

Question 5

On a construction site a lot of labor/skill is needed as one start the project but as you scale down on the

works, there is a tendency to reduce on the workforce,

a. Discuss how you factor the downsizing of the workforce when preparing the bill of quantities?

.

b. Discuss the importance of quantity surveying to Civil Engineering?

c. With clear labeled diagram, how do you carry out quantity take off for road, dam and water

project respectively?

During construction, field tests were conducted to assess the suitability of the column to
withstand a safe buckling load of 2.5 kN assuming a factor of safety 4 using two different hollow
columns made up of steel and concrete. Both columns have same cross section but varying length
and different support conditions. Steel column of length 3 m having external diameter 40 mm was
tested with one end fixed and the other end hinged, when subjected to a compressive stress of
0.0045 MN/cm2 shortens by 3.6 mm.
If the concrete column was tested under similar loading conditions with one end fixed and other
end free considering modulus of elasticity of concrete equal to 128 GPa, what will be the
corresponding length of the column required? As a design engineer how do you choose the values
for the thickness of both columns and the length of the concrete column? What will be your
interpretations regarding the relationship between the support conditions and the buckling load
based on the test results?

Henry Royce, purchasing agent for Pendleton Construction Inc is currently in the process of selecting a steel supplier/fabricator for a major highway project. Pendleton is one of the largest heavy-highway construction frims in the Midwest. The company builds bridges, high-rise office towers, power plants, goverment buildings and roads. Pendleton has a reputation for high-quality standards, on-time project completion and reasonable prices. The company has expanded rapidly during the past 20 years, keeping pace with the heavy highway sector.

Reinforced steel is used in almost all of Pendleton's projects. The steel itself is purchased from one of several large steel mills in the region. During the past 18 months, the fabrication (bending) required in preparation for steel placement had been done by Mohawk, a small local disadvantaged business enterprise specialty steel fabricator. Pendleton's total steel-bending requirement for the most recent fiscal year was approximately 5000 tons. Mohawk had charged identical prices per ton for both small and large steel fabrication jobs. Prior to bidding on a project, Royce requests a telephone quotation from Mohawk and the price per ton quoted is the same as the previous bid. Mohawk is also a supplier of specialty steel. Royce has an exlclusive agreement with Mohawk to supply specialty steel items on short notice. This arrangement has worked well for Pendleton. Mohawk also owns a major share in a detailing firm that did approximately 70% of the reinforced detailing work for Pendleton. According to Royce, Mohawk has done an excellent job supplying high quality specialty steel to Pendleton. At the same time, he stated Mohawks fabrication work was pretty good.

Recently Pendleton was awarded a mega highway project in southern Indiana that will require more than 9780 tons of reinforced steel for three consecutive years. Because of the size of the project, Royce decided to solicit quotes from other sources for fabrication work. However, Pendleton bid the project using Mohawk's fabrication estimates. Royce received three quotes for the fabrication work item. All three estimates were lower than Mohawk's bid quote. The quotes were $7, $8 and $9.50 lower than Mohawk's estimate. The company with the best estimate which was $9.50 lower than Mohawk's esitmate, had recently filed for bankruptcy. However, the remaining two suppliers check out as being well run and financially healthy. Baker Steel quoted a price that was $8 lower per ton F.O.B. the job site. Baker was a major steel fabricator located in Cleveland, Ohio, which is approximately 350 miles from the project site. The quote was made on the condition that all transport shipments be full loads, with no emergency short shipment transport charges. Royce had carefully checked out Baker's business capability and reputation and found that it had performed quite well throughout the Midwest.

Royce felt that he needed to make a rational decision. He now wondered if he should place that steel-bending contract with Baker or whether he should stay with the Mohawk bid. What are the implications of his decision?

Please answer the following 3 questions about this case...

As Henry Royce, which specialty fabrication supplier would you select for the newly awarded megaproject?

Explain your choice in detail.

Regardless of your choice, what would be the implications of not awarding the contract to Mohawk?

Patricia, a CPA, is the new controller for a small construction company, Domingo Builders, that employs 75 people. The company specializes in custom homes greater than 3,500 square feet. The demand for large custom homes has significantly decreased because of the downturn in the economy. As a result of economic conditions their target market is dwindling, significantly affecting the company’s finances.

The ability to collect an outstanding receivable that is significant and material is in doubt. Prior to year-end Patricia discusses the outstanding receivable with the CEO. Patricia believes that the company owing the outstanding receivable will not last for another year. Patricia believes that the allowance for uncollectible accounts must be adjusted to a value that is reasonably realizable. The CEO disagrees.

The CEO is concerned that if the allowance adjustments are made, then Domingo will not look financially sound. Additionally, the CEO is concerned about the opinion that the auditor may provide as a result of the allowance adjustment. Anything less than a “clean opinion” would jeopardize Domingo’s ability to secure a much-needed bank loan. If the company cannot secure the loan next year, then Domingo might be out of business too.  

The CEO urges Patricia to ignore the allowance adjustment. After all, it is not certain that the outstanding receivable will be uncollectible; the company has not filed for bankruptcy. The CEO believes that Domingo can just weather the storm and will recover from the economic downturn. “I know business will pick up”.

Patricia reflects on what can be done. From her previous experience in public accounting, Patricia reflects on the audit process and information that she thinks the auditors would need to know.

In a soil investigation for a construction project, two soil types were identified with the following parameters (g = 9.81 m/s²):

If the ground water level is at 2.5 m below the ground level, and the initial void ratio of the overconsolidated clay layer is 0.69, find the expected settlement in the clay layer only due to a proposed foundation that should imposes a pressure of 60 kN/m² on the mid-depth of the clay layer. The overconsolidation pressure is 125 kN/m². What is the the total settlement due to both the sand and clay layers (to the mid-height of the clay layer)?
