Using the grid elevations obtained from the site contour data, calculate the volume of

earthwork required to grade the lot to the finished elevations indicated below. ALL

calculations must be submitted to get full marks.

The lot is to be graded to a downward slope of $0\mathrm{.}5\%$ from E to W from line G at an elevation of

$460\mathrm{.}00$

Grid size is to be $10m10m$

Compaction factor $=0\mathrm{.}80$

Swell factor $=0\mathrm{.}77$

Determine:

a$)$ Volume of Fill Material $-$ bank measure

b$)$ Volume of Cut Material $-$ bank measure

c$)$ Volume of fill required$-$loose

d$)$ Volume of cut to move $-$ loose

e$)$ Volume of import or disposal

f$)$ Number of truck to remove$/$ haul material, if a

tandem dump

truck can haul $18\mathrm{.}5m^3$ of loose material.
