A D8 track-type dozer with a universal blade will be used to push a material. The average push distance of 800 feet. In addition to this push distance, the dozer typically can load it's blade in 50 ft and can feather the fill (i.e., place a lift of approximately 6 inches) in 50 feet. The material has a typical unit weight of 2300 lbs/Icy. Job efficiency for the dozer is estimated to be equivalent to a 48-minute work hour. The blade characteristics are as follows: width is 15 ft; height is 9 ft; wing length is 3 ft, and wing angle is 10 degrees. Assume average speed in first gear is 2.5 mph, average speed in second gear is 4.5 mph, and average speed in third gear is 8 mph. Assume 0.4 minutes for maneuver time for the dozer. The shrinkage factor for the material is 0.88 and the swell factor is 1.13. The O&O cost for the dozer is $1819 per 8-hour work day. Determine the daily production for the dozer and determine the unit cost to move earth using this dozer. NOTE ANY AND ALL ASSUMPTIONS. Daily production for dozer Icy Unit Cost $/icy Assume that the fill being pushed by the dozer needs to compacted. An 815 compactor with a single drum width of 39 inches and speed of 3 mph will be used to compact the material. Assume it takes 4 passes to compact the material to the specified compaction and the efficiency for the compactor is 0.65. Answer the following questions. The O&O cost for the compactor is $1445 per 8-hour work day. What is the daily production of 1 compactor? ccy/day Including the cost for compaction, what is the new unit cost to move and compact the earth? $/Icy A D8 track-type dozer with a universal blade will be used to push a material.
