Volumes of Earthwork CUT AND FILL The amount of cut and fill is determined by several approximate volume determination methods. i. The average end area method Figure 1. Typical Prismoidal Volume Where V = volume of cut or fill (yd 3 ) A1 , A2 = end areas (ft 2 ) L = distance between end stations (ft) For fill, since there is considerable settlement in the soil Where f is the shrinkage factor and ranges between 1.10 to 1.25. 27 ) 2 1 ( 2 1 A A L V 54 ) 2 1 ( A A L V ) 1 ( 54 ) 2 1 ( f A A L V A1 L A2

OVERHAUL AND COST ESTIMATION There are two methods to determine the amount of overhaul, the two methods are the graphical method and the method of moments. i. The Graphical Method The Mass Haul Diagram is a graphical representation of the net amount of cut and fill and the direction of haul along the length of the project. Note that rising portions of the mass haul curve indicate areas where excavation exceeds fill. e.g. Section C'D' in Figure 2 below.
