A site $150m250m$ is to be stripped and reduced to design level and the material

removed. The estimated volume is $18,000m^3$ of clay and $10,000m^3$ of topsoil $($assume

this is the "solid volume" from design$).$

There is good flat access to the site and tipping space is available $2\mathrm{.}5$ km away. The job

needs to be completed in $10$ weeks working a $40$ hour week.

Determine the numbers of loaders and trucks required to perform the earthwork.

State any assumptions you make.

Assumption: for clay consider $30\%$ expansion & for top soil consider $20\%$ expansion

Tip: Assume reasonable capacities for the loader bucket & trucks in $m^3($e$.$g$.1\mathrm{.}5m^3$

for loader bucket and $14m^3$ for truck$)$
