The image shows the plan of a site that is 60mx40m overall with a grid laid out at 10m in center. The elevation (in meters) of the existing grade is shown at each Intersection point of the grid. Calculate the volume of cut and the volume of fill in cubic meters required to level this site to a new grade of 100.0 m over the entire area.
Sample responde format Summary
1 total volumen cut = (include the unit of measure)
2 total fill volume = (ditto)
Figure 4.15 shows the plan of a site that is 64' × 160' overall, with a grid laid out as shown. The elevation (in feet) of the existing grade is shown at each intersection point on this grid. Calculate the volume of cut and the volume of fill in cubic yards required to bring this site to the new grades shown on the plan.
Discuss the advantages and disadvantages of calculating volumes of cut and fill by using the “grid method” rather than by using the “section method.”
