QUESTION $2$

Longitudinal section

$2\mathrm{.}1.$ Use the following scale and calculated final heights to plot the longitudinal section from stake values SV$140$ to SV$220,$ which are $20m$ apart. $($Graph paper is provided on the next page$).$

$(4)$

Vertical Scale $4$ Blocks $=1m$

Horizontal Scale: $3$ blocks $=20m$ and $1$ block $=5mm$

$2\mathrm{.}2.$ The first formation height at stakevalue SV$120$ is given as $717,750$ and formation line touches the ground at SV$200$ calculate the rest of formation heights and carry out the check calculations.

$(4)$

$2\mathrm{.}3.$ Calculate the Cut and Fill from the formation heights and ground heights. $(2)$
