calculating the cubic yards to be moved. That's the heart of every earthwork estimate. I'll cover quantity estimating in detail. Then I'll explain how to find labor and equip-ment costs per unit. We'll also consider soil and rock properties and how the equipment you use affects bid prices. Why Calculate Quantities?

one cubic meter of soil that is excavated from the ground may occupy 1.25 cubic meters after it is loosened and placed in the hauling unit. After the soil is compacted in place it may occupy 0.9 cubic meter. The soil to be excavated is called bank measure, in its undisturbed condition, prior to excavating or after being compacted in place.
Earth moving Equipment are used in the construction projects, in order to prepare a plan and time schedule for such activities you should be aware of different types of Earth moving Equipment and the productivity for each Equipment (how much cubic meter of soil can be moved or excavated in a certain amount of time or how fast material can be transported).

Open pit mining Mining Methods 5 Open pit mines are used to exploit low grade, shallow ore bodies. However, some pits are quite deep – about 1 km. The mining rate is greater than 20,000 tonnes per day (tpd) but is usually much greater. Some pits operate at a rate of more than 100,000 tpd

part to the Handbook. Open-cut miners will always refer to soil quantities as 'bcms', but we like to think of it as 'undisturbed' cubic metres. CCM: This describes soil after it has it is compacted. Once again the degree of compaction needs to be established, and this is achieved with the help of densities, and density ratios.
