QUESTION $1$

$1\mathrm{.}1$ Draw the longitudinal section using the stakevalues and ground heights provided in the table $1$ and draw formation line starting at stakevalue $40$ at height $1441,000$ and crossing natural ground at stakevalue SV$120.($Graph book provided on next page$(6)$

$1\mathrm{.}2$ Calculate the formation heights for all other stakevalues and carryout necessary checks. $(6)$

$1\mathrm{.}3$ Using calculations determine if you would be required to cut or fill the ground at each stake value. $(2)$
