The following table shows chainage and corresponding cut and fill for a proposed road construction. Determine (a) each section's excess cut or shortfall (b) the most efficient equipment for cut, fill and hauling assuming there is no rock present (c) draw the mass haul diagram and indicate cut, fill, excess cut or shortfall fill Costs are listed below: Dig and form banks up to 200m haul, $0.9 per m; Dig and form banks between 200m and 300m haul, $2.4 per m; Dig and form banks between 300m and 400m haul, $4.8 per m; Cart to tip, $1.5 per m; Bring from borrow pit, $2.3 per m Determine (a) the cost for each combination of haul, cut and fill for 200m, 300m and 400m haul (b) plot the cost of each respective haul distance and then determine the economic haul distance Chainage 0~ 200 400 600 800~ 1000 1200 1400 1600 1800 Total (m) 200 400 600 800 1000 Cut (x1000m3) Fill (x1000m3) Bulking factor 10% included Cumulative Volume Cut less Fill i.e. Excess Cut +ve Shortfall Fill -ve 40 70 0 0 30 0 0 0 18.2 36.4 N N 45.5 N 18.2 1200 1400 1600 1800 2000 0 0 40 40 0 N 0 N 0 18.2
