A medium hydraulic excavator will be used to dig a trench in hard clay. The minimum trench size is 36 in. wide with an average depth of 5 ft. The excavator bucket available is 38 in. wide and has a heaped capacity of 2.0 cu yd. The maximum digging depth of the excavator is 16 ft. The average swing angle is expected to be 85 degrees. Estimate the productivity in BCY and hourly trench production in linear ft if job efficiency is 85%.
