3) For the construction of the final stage of auniversity laboratory building, the site engineerdecided to purchase 12 beams whose value (indollars) varies according to the length of thebeam. In the last quote received by the engineeris the unit cost that the 12 beams would have, itis as follows:25002600 25502480 2560 25702490 2490 2530 2510 24902410a. The lot purchase criteria establishes that itshould be acquired if its average cost does notbelong to the cheapest 10% of lots or to themost expensive 10% of lots that have beenpurchased for the construction of the entirebuilding. If it is known that the beams that havebeen purchased throughout the project havehad a normally distributed cost with an averageof $2,540, what should the engineer's decisionbe and why?b. What must be the minimum and maximumaverage costs of the lot so that it can bepurchased?

Calculate the cost per cubic yard to place concrete using each of the alternatives described. The work in both cases consists of placing 140 cubic yards of concrete in footings. a. Using a crane and bucket at a price of $225 per hour, including an operator, with a crew consisting of 6 laborers, a cement finisher, and a foreman. The concrete will be placed in 7 hours using this setup, and transportation of the crane costs $390. b. Using a concrete pump at a price of $295 per hour, including an operator and a crew consisting of 5 laborers, a cement finisher, and a foreman. With this setup, concrete is placed in 6 hours and transportation of the pump costs $290.
ABC Construction Company enters into a contract with XYZ Municipality to construct a new public library. The project has a strict deadline due to an upcoming community event, and the municipality is keen to have the library completed well in advance. To incentivize ABC Construction for early completion, the parties agree on a fixed price reward contract. As the construction progresses, ABC Construction faces several challenges, such as inclement weather, delayed material deliveries, and unforeseen site conditions. Despite these obstacles, the company manages to complete the project two months ahead of the agreed-upon deadline. In this scenario, how does the fixed price reward contract benefit ABC Construction Company? What are the specific terms and conditions associated with the reward? How can ABC Construction effectively claim and receive the reward from XYZ Municipality? Additionally, what legal considerations should ABC Construction be aware of when entering into a fixed price…

A contractor is considering the purchase of an earthmover to avoid the cost of a rental unit. The earthmover costs $350,000 initially and will cost $7000 per year to store and maintain. When used, the operating cost is $300 per day to the contractor. A rental unit costs $500 per day to rent and operate. The contractor estimates that he would keep the earthmover for 20 years and could then sell it at salvage for $20,000. He requires a 12% rate of return on any investment. Determine how many days per year he would have to operate the earthmover to make it a worthwhile purchase. Sketch the breakeven chart for this situation.
