64. In calculating the number of cubic yards of earth to be excavated for the cellar, all the measurements are taken from the foundation plan and the sections. The method pursued in making calculations is as follows: The plan is blocked out as shown in the accompanying "Cellar Plan," and the area of each block is determined; then, by multiplying the sum of these partial areas by the depth of the cellar, the cubic contents are determined. The trenches for the foundation walls of porches and for the footings of cellar walls are calculated separately, as also are the excavations for piers, drains, cesspools, area, etc.
