The earthwork volume sheets allow you to systematically record this information and make the neccessary calculations.
They provide a means of tabulating earthwork quantities for use in the mass diagram discussed. The earthwork volume calculation sheet, shown in image, is divided into columns for recording and calculating information.
List in column 1 all stations at which cross-sectional areas have been plotted. Normally, these areas are taken at all full stations and at intermediate stations that are required to fully represent the actual ground conditions and earthwork involved.
Record in column 2 the computed cross-sectional areas of cut at each station. These areas may be computed by one of the commonly used methods, depending on the degree of accuracy required.
Complete column 3 in the same manner as column 2, except show cross-sectional areas of fill.
