Backhoe excavator worked for 45 hours to excavate and stock the required earth volume to be loaded by a payloader to a fleet of 5-dump trucks, which haul the earth to site where it is compacted on a shrinkage factor of 20%. Each truck has a total cycle time of 15 minutes, assuming it does not have to wait in line to be loaded. The earth has a percent swell of 25%. The job requires a compacted volume of 30,000 m 3 done by a road grader, roller compactor and water tanker in 70 hours. Calculate the direct equipment total cost spent considering the following? a. Payloader capacity – 220 m 3 (bank volume) of common earth per hour. b. Dump trucks capacity – 20 m 3 (loose volume) each unit c. Payloader rental rate – ₱650/hour d. Dump truck rental rate – ₱180/hour e. Backhoe rental rate – ₱800/hour f. Road grader rental rate = ₱ 550/hr g. Roller compactor rental rate – ₱750/hour h. Water tanker rental rate – ₱ 120/hr
