File name is ENLE. This program is designed to calculate "level section" center line grading quantities from data taken from a line located on contour sheets. The program is of great benefit in helping location or design engineers in estimating quantities based on different alignments or grade variations. The program accepts roadbeds of various widths or slope and as many as two benches and/or two berms. It will convert grade line information into subgrade elevation for each level section and determine whether the section is in cut or fill, if benches or berms are involved, and will calculate the applicable end areas and volumes taking vertical curve corrections into account. The program will determine where 0.0 sections occur and where benches and berms begin and end. Output will include, at each engineering station shown in the input, the cumulative embankment volume; cumulative excavation volume; cumulative rock excavation volume. (This is a percent of the total excavation. The percentage used is input and can vary from cut to cut); subgrade elevation, center line ground elevations, and height of fill and/or depth of cut; output will also include engineering stations at calculated 0.0 sections and beginnings and ends of benches and berms. Sections need be shown at major break points only; the program will interpolate all intermediate stations and end areas so as to reduce the error factor. Grade elevations are input separate from ground elevations which allows analysis of several grades or combinations of grades with a given ground line profile. Another use of the program would be in estimating contractors "pay quantities" where the ground line would vary monthly as compared to a fixed grade line.
