Using this example, we would estimate that the required fill of the westernmost fifth of the site would be 278 CY. With Cut and Fill you’ll produce more accurate earthwork estimates in less time.
The software then determines the cut and fill quantities and graphically displays the results. ("Station") (Fill Area) (Average Fill Area) (Volume) You can quickly calculate cut, fill, and strip quantities by simply digitizing the boundary of work, contours, layers, elevations, etc., for the existing and proposed surfaces. For example, the computation for the fill volume between stations zero and a half is shown (all units are "English"): The volumes were computed using a spreadsheet. Where - is the proposed grade and, or ' is the existing. ArcView GIS was used to delineate and create coverage maps and produce query data. Design drafting and GIS mapping of vegetative communities for New York City DDC. The area beneath where the existing grade exceeds the proposed was reserved for a cut computation. determination of cut and fill calculations as well as storm water drainage, contour mapping, and landfill gas extraction systems. The area beneath where the proposed grade exceeds the existing was reserved for a fill computation. For each section, we plotted the existing elevations and the proposed elevations. To help us organize the sections, we defined the east PL as station zero, and then we marked every half station on the plot until the west PL. To level the site for purposes of water storage, we are mostly filling it up beginning at the SW corner.īased on a drawing showing the PLs, existing and proposed contours, we took six sections of the site at 50 ft intervals from the west PL to the east PL. The site is a rectangle that is high in the NE corner and deep in the SW corner. We began by reviewing the site and defining the grading concept. Since we are just wrapping up a cross-sectional analysis for a site design by hand, I want to share our easy method, if not just to provide a perspective. It is real simple to produce an estimate of cut and fill volumes.
