### Excavation in Construction from Construction KnowledgeTable 10-1Soil Conversion Factors

Another common breakdown in excavation work is bulk excavation and trench excavation Swell and shrinkage are two important, and often misunderstood, terms Consider the simple example of digging a 10 cubic yard hole with a shovel and throwing the dirt into wheelbarrowseconomical haul distance is the mass diagram method A mass diagram is a graph or curve on which the algebraic sums of cuts and fills are plotted against linear distance.

It is the increase in volume of a given quantity of sand, a phenomenon that is not present in gravels The bulking factor has to be taken very much into account at the time of calculating the excavation production and assessing transportation requirementsEarthworks - Durham University Community Excavation increases the volume of material It is therefore necessary to use a bulking factor to determine the volume of material that will be created by excavation.
