- A project to move packed earth requires you to decide whether to usea dozer/scraper operation or excavator/truck operation. Determinethe most economical operation based on the dozer/scraper operationestimated at $1.25/cy. All equipment carries a rated heaped capacity, hasa fill factor of 100%, and works 45-min hours. Excavator costs $95/hr（including operator), cycle time is 0.28 min, and bucket heaped capacityis 5.0 cy. Truck costs $150/hr.(including operator), dump time is 0.5 min（maneuver, dump, turn), heaped capacity is 31.7 cy, and 12 trucks areavailable for the project.Hauling equipment operates in one directionfrom A to B to C and finally to D.

- please solve this perfectly. subject: : Project Planning, Management & Engineering Economics. A road building contractor has received a major highway construction contract that will require 50,000 m3 of crushed stone each year for 5 years. The needed stone can be obtained from a quarry for S5.80/m3. As an alternative, the contractor has decided to try and purchase the quarry. He believes that if he owned the quarry, the stone would only cost him $4.30/m3. He thinks he could resell the quarry at-the end of 5 years for $40,000. If the contractor uses a 10% interest rate, evaluate how much would he be willing to pay for the quarry?2) A contractor imported a bulldozer paying P500k to the manufacturer, freight & insurance charges amounted to P18k, customs & brokers fee P10k, permits & other exp P25k. If the contractor estimates the life of the bulldozer to be 20 years with salvage value of P50k, determine depreciation for year 9 and book value at the end of year 9 using Straight line and Matheson Method. 4) A drilling machine may be used to dig ditches. The contractor purchased it for P200k & estimates that it will be able to dig 750k meters during its life and he expects to receive 10% as scrap value when he sells it. What if during a certain year he used the machine to dig 150k meters of trench, determine depreciation cost for that year. 3) During the month of May a mining company has a gross income of P5M from the production of gold. All expenses excluding depletion for this month was P1.8M. If fixed depletion rate of gold is 15% what is the depletion allowance for this month?Describe about the Alternative Methods of Transporting Earth Fill.
