Road/ Drain/ Canal: Cross Sectional Drawings and Quantity Estimation of Earthwork in Cutting and Filling

Based on Contour elevations of survey points and Horizontal and Vertical Curve Design of Road or any Land Development/ Land Improvement Plan the difference between existing ground and final proposed formation ground is plotted as cross sectional drawings which shows area at that particular section in earthwork cutting and filling. This are average between two sections multiplied by length gives quantity and estimate of work. I have done quantity estimation for road, new land development, plotting, canal, drain etc.
