Question $1$: $(80$ points$)$

Design and prepare the BOQ for VCP gravity flow sewer main starting at the intersection of $4$ th and G Streets and ending at the intersection of $2nd$ and B Streets $($Figure below$).$ Prepare a sewer design table and a profile drawing. Use the following assumptions: minimum invert depth is $3\mathrm{.}0m,$ the invert of the sewer entering the main from G Street $($east and west$)$ is at an elevation of $102\mathrm{.}13m.$ Contributing flows, including I$/$I$,$ from mains are given below.
