A contractor plans to use three Caterpillar 623E elevating scrapers to excavate the face of a hill to create a level building site for a small industrial complex. Since the work will be done in January, the working conditions will be considered severe. The productivity of each scraper is estimated to be 87 cubic yards per hour when operated under severe working conditions. Each scraper operator earns $22.50 per hour. Using Figures 5.4 and 5.5, what is the estimated equipment cost for this excavation operation, if the volume of material to be moved is estimated to be 12,750 cubic yards? (use the summary rate of $125.31 per hour operating under severe conditions) This topic is Construction Management but it's like applied accounting and management so I guess Operational Management works too? From textbook Construction Equipment Management by Schaufelberger CHP 5 E#4.
