Part $1,($Topographic Mapping, contouring, longitudinal sections and cross$-$sections$)$

A road is proposed along the shown centerline $i-i.$ The road is proposed to have $10\mathrm{.}0m$ formation width, and a side slope of $1$:$1.$ The starting RL on the starting western point of the road is $35\mathrm{.}35m$ and the proposed gradient of the road is $1$:$100$ upward.

Redraw the above grid on the provided graph paper to a scale of $1$:$500$

$(10)$ points$)$

On the graph paper, draw contour $35,36$ and $37$ using an interpolation method of your choice.

$(15$ points$)$

Draw the longitudinal profile $($longitudinal section$)$ of the land along the proposed centerline of the road i$-$i to $1$:$500$ horizontal scale and $1$:$100$ vertical scale. $(15$ points$)$

Draw the formation of the proposed street on the longitudinal section of the land that you produced in part $C$ of this problem. And on it mark the locations of maximum cut and maximum fill, if available.

$(15$ Points$)$

Produce the chainage, RL$,$ FL$,$ Cut& Fill data table.

$(15$ points$)$

On the provided graph paper, draw the cross$-$section of the road at a distance of $60\mathrm{.}00$ meters from the beginning of the road $($along the line KR$)$ to appropriate horizontal and vertical scales. Make sure to write the scales that you used below the cross$-$section plot.
