Problem:

Make a set of level notes and a grade sheet showing the cut$//$ill to write on grade

stakes $A$ to $T$ as shown on the given site grading plan. Part B $-$ Construction Surveys

A storm sewer is to be constructed from existing MH$4($invert $=129\mathrm{.}1$dotsm $)$ at

$+2.{?}_{\%}$ for a distance of $82m$ to proposed MH$5.$

The remaining $2$ numbers of your existing MH$4$ invert will be the

last two digits of your student number.

i$.$e Student number $0403682,$ invert $=129\mathrm{.}182m$

The remaining $1$ number of your slope will be the second digit of

your student number excluding leading zeros.

i$.$e Student number $0403682,$ slope $=+2\mathrm{.}0\%$

The elevation of the offset grade stakes are as follows:

$0+000(MH4)=132\mathrm{.}586m$

$0+020=131\mathrm{.}598m$

$0+040=133\mathrm{.}002m$

$0+060=133\mathrm{.}900m$

$0+080=134\mathrm{.}254m$

$0+082(MH5)=133\mathrm{.}986m$

Prepare a grade sheet showing stake to batter board distance. Select an

appropriate batter board length. The cross section below has the following elevations:

Proposed CL Elev. $=126\mathrm{.}2$dotsm.

The remaining $2$ numbers of your slope will be the first two digits of

your student number excluding leading zeros.

i$.$e Student number $0403682,$ Proposed CL Elev. $=126\mathrm{.}240m$

Stake A Elev. $=128\mathrm{.}7$dotsm.

Stake B Elev. $=123\mathrm{.}4$dotsm.

The remaining $2$ numbers of your Stake A and $B$ Elev will be the

last two digits of your student number.

i$.$e $,$ Student number $0403682,$ Stake A Elev. $=128\mathrm{.}782m$

Student number $0403682,$ Stake B Elev. $=123\mathrm{.}482m$

a$.$ Calculate the elevation of the bottom of the ditch

$\frac{?}{3\mathrm{.}5}$

b$.$ Calculate the horizontal distance from road CL to slope stake A $/3$

c$.$ Calculate the horizontal distance from road CL to slope stake B

$\frac{?}{3\mathrm{.}5}$The intersection below has the following centerline elevations and azimuths:

BC CL Elev $($Sta$.0+444\mathrm{.}785\_m.$

The remaining $2$ numbers of your $BCCL$ Elev will be the first two

digits of your student number excluding leading zeros.

i$.$e Student number $0403682,$ BC CL Elev. $=222\mathrm{.}440m$

EC CL Elev $($Sta$.2+111\mathrm{.}555.$

The remaining $2$ numbers of your EC CL Elev will be the last two

digits of your student number.

i$.$e Student number $0403682,$ EC CL Elev. $=222\mathrm{.}182m$

Back tangent azimuth $=108\_-\text{'}{59}^{\text{'}\text{'}}$

The remaining $2$ numbers of your back tangent azimuth will be the

first two digits of your student number excluding leading zeros.

i$.$e Student number $0403682,$ back tangent azimuth. $=108{40}^{\text{'}}{59}^{\text{'}\text{'}}$
