Excavation Rate 1

[blackford]

I need to work out the £ per cubic metre (+10% profit margin) for the following:
EXCAVATOR data:
180 degree output 50cu m/hr
costs including operator = £600 per/day
Lorries: 10 cubic metre capacity. Cost including driver = £300 per/day
SITE data: 5000 cubic metre excavated. Haul distance is 4kl at average speed of 30km/hr. lorry loading time 12 minutes and tipping time 4 minutes. Tipping charge £2 per cubic metre. Bulking factor for material expected to be 25%.

So do it. Use the education you have to do the math.

Total £37,727

Cost £6.04 per m^3
