Question #3 (7 points) - Use the information from the CAT Performance Handbook to answer the question. A contractor wants to move a loose stockpile of material onsite using an SU blade on a D9T dozer. The material is a clay, and is to be moved a distance of 400 ft, based on a center of mass to center of mass distance. The dozing occurs downhill on a 20% grade. The operator will have average skill and the operator is working is foggy conditions. The operator will be using a slot dozing technique and the material weighs 2,250 lb/LCY. Job efficiency is assumed to be equivalent to a 40-min hour. You are to calculate the direct cost of the proposed earthmoving operation in dollars per bank cubic yards ($/BCY). Assume that the hourly cost for the dozer including the operator is $135/hr. (a) Using the CAT charts on the following pages determine the following: Ideal Maximum Production (LCY/hr from CAT chart): Material-Weight Correction Factor: Operator Correction Factor: Material-Type Correction Fact Operating-Technique Correction Factor: Visibility Correction Factor: Operating Efficiency Factor: Grade Correction Factor: (b) Determine the dozer production rate in bcy per hour, when the load factor of the material is 0.83. (c) Determine the overall production cost of the proposed earthmoving operation based on bcy ($/bank cubic yard).
