A contract is being bid to clear aid grub 147 eats. You KC Ittimating the cont associated with using either of two different power-shift dozen. One dozer is a 215-1ap model and the other Is rated at 335 hp. The 215-bp has an O&O eoa4 without °piece. of 543 per hour and the 335-hp's O&O is 563.96 per bout. The wage determination for beavy-duty operators is 510.85 per hour. Project overhead will am 5357 per workday. Assume a 10-hr workday. A field engineer has made a site visit and provided you with the following information. The site is rus Onably level and the machines will have no problem with bearing or traction.

Burning will require that the dozer be employed twice the time expected fee piling-op alone.
a. What is the estimated clearing and grubbing production rate for each dozer?
b. What is the cost associated with the total operation, including overhead. when only one 215-hp dean is used?
c. What is the cost associated with the total operation. including overhead, when only one 335-hp dozer is used?
d. Is it cheaper to employ dote 215-hp &um or two 335.hp dozers?
