QUESTION ONE
Calculate the unit equipment and labour prices per cu. yd. to excavate 4,000 cu. yd. of the trench using a 3/4 cu. yd. backhoe costing $670.00 per day rental (8 hours) plus $3,000 for transportation and setup charges. The expected equipment output is 60 cu. yd. per hour and managed by an operator and 50 % time of a labourer at wages of $45.00 and $35.00 per hr, respectively. Also, what is the total cost to excavate the 4,000 cu yds. of material? Assume a fraction of a day rental cost is the whole day rental cost. SOLUTIONS

As a result, the costs of labor and equipment per cubic yard are 1.04 and 2.14 dollars, respectively. Therefore, the total cost of excavating 4,000 cubic yards of material is 4160 + 8560 = $12720. QUESTION TWO
Calculate the unit equipment and labour prices per cu. yd. to excavate 400 cu. yd. of trenching with the same equipment and crew as listed in the question above this one. What is the lesson learned from these two exercises? SOLUTIONS

1.04 8.9 Therefore, labour and equipment costs per cubic yard are $1.04 and $8.9, accordingly. The lesson learned is that because the quantity of labour required is so much less, total equipment productivity will almost certainly be reduced, but even if it stays the same, the price per unit of work will rise. As the volume decreases, the unit price rises
.
QUESTION THREE
The hourly rental cost for an excavator is $172.00/hr, the operator wage rate for this equipment is $40.00 per hour, and the expected productivity of the excavator is 50 cu. yd. per hour. Calculate the unit prices for labour and equipment for these conditions. Use these unit prices to determine the total cost to excavate 4,800 cu yds. of soil. Assume the excavator uses 10 gallons of diesel/8 hr-day and the cost of diesel is $3.00/gal. Answer: Given, a daily fuel usage of 10 gallons/8 hours. Fuel cost for a day is 10 x 3 = $30 and Fuel cost per hour is 30/8= $3.75
