The following information are required in preparing earthwork cost estimation progress
claim to the client as soon as possible:
(a)
Plot a mass-haul diagram between the chainage 4000m to 4700m using the volumes
obtained in Table Q5. Use a scale of 1cm = 50 m for the x-axis and 2 cm = 500 m3
for the y-axis.
(b) Estimate the haulage costs between the chainage 4000m to 4450m. Proposed
balancing line and free haul distance are at +4000m3 and 200m respectively. The
transportation charges are:-
: RM 1.50 / m3
: RM 0.80 / stn. M.
Free-haul
Over-haul
Assuming that the balancing line of +3500 m3 is to be applied to the mass-hall diagram
calculations, explain how this would affect the cost estimation.
