A 7000 meters long and 8 meters wide road is to be constructed in a remote region. Cut and fill are necessary where there is a poor subgrade soil. Four bulldozers excavated the poor subgrade soils. The dimensions of the excavated trench were 0.8 m deep by 10 meter wide and 3.5 kilometers long. The road will have 100 mm aggregate base and 50 mm of asphalt thickness. A bulldozer displaced 115 m³\day, at a rate of 100 cedis per day. A laterite soil will be used in the fill operation. The fill operation will need a grader, a vibratory roller and a water truck for 20 days each at a cost of 130 cedis, 138 cedis and 68 cedis respectively. Daily labor rates for this excavation operation is a foreman, 30 cedis, five laborers, 15 cedis each. Truck driver, 21 Cedis and grade checker, 26 Cedis. Daily labor rates for the fill operations are the same as the excavation rates. One forman, ten laborers and a truck driver will be employed for the fill operations.

Question
Transcribed Image Text:A 7000 meters long and 8 meters wide road is to be constructed in a remote region. Cut and fill are
necessary where there is a poor subgrade soil. Four bulldozers excavated the poor subgrade soils. The
dimensions of the excavated trench were 0.8 m deep by 10 meter wide and 3.5 kilometers long. The road
will have 100 mm aggregate base and 50 mm of asphalt thickness.
A bulldozer displaced 115 m \day, at a rate of 100 cedis per day. A laterite soil will be used in the fill
operation. The fill operation will need a grader, a vibratory roller and a water truck for 20 days each at a
cost of 130 cedis, 138 cedis and 68 cedis respectively. Daily labor rates for this excavation operation is a
foreman, 30 cedis, five laborers, 15 cedis each. Truck driver, 21 Cedis and grade checker, 26 Cedis. Daily
labor rates for the fill operations are the same as the excavation rates. One forman, ten laborers and a
truck driver will be employed for the fill operations. Grading and asphalt laying will require: fine grading
and crew 848 cedis per day for 12 days Base preparation crew and equipment for 10 days at 780 Cedis per
day. Paving crew and equipment for 5 days at 848 Cedis per day, prime equipment and crew for 5 days at
446 Cedis per day. Seal equipment and crew for 8 days at 332 Cedis per day. Add 10 percent as overhead
cost.
