Question 20 12 pts You are planning an excavation activity using a hydraulic excavator with a bucket capacity of 3 CY and a maximum digging depth of 25 feet. The material for this excavation is a well blasted rock giving a bucket fill factor of 75% and a swell percent of 60%. The swing angle is 50 and the average depth of the cut is 14 feet. The cost of the excavator and operator is $170/hr and on this operation a 45 minute hour is anticipated. The standard cycle times (including adjustment for dumping into a truck) for this machine are as follows: Load time - 7 seconds Swing loaded time - 6 seconds Dump bucket - 5 seconds Swing empty - 4 seconds What is the cost per Bank Cubic Yard to excavate this material? Round your answer to the nearest thousandth.
