Amount of borrow needed to bring area to elevation of 90-ft, Civil Engineering

Assignment Help:

Surveyed elevations are shown in Figure for a 50' x 50' grid at a proposed parking lot location. The amount of borrow needed to bring the area to an elevation of 90-ft is most nearly:

967_amount of borrow needed to bring the area to an elevation.png

Solution:  

Find the average elevation:  

Average   = 87.6-ft + 87.6-ft + 87.6-ft + 88.6-ft / 4                  

Average =   87.85-ft  

Change = 90-ft - 87.85-ft

   in elevation  = 2.15-ft

 Fill Required   = 2.15-ft   x 50-ft x 50-ft

      = 199-yd3
