Civil Estimating Tutorial - Calculating Cut and Fill by the Grid Method
The grid method of calculating excavation and fill is based on multiple elevations determined by a survey of the site.
The site is laid out into a grid. The existing grade is determined and the finished grade is determined at each location on the grid.
By adding or subtracting the elevations, the estimator calculates the depth of cut or fill at each point where the grid lines intersect.
