Problem $2$

Our footing from above is cured enough to form and place our $22"$ thick retaining wall. For

this problem, please consider the volume of reinforcing steel negligible.

The top of footing elevation after being as$-$built was determined to be $35\mathrm{.}028\text{'}.$ Our new

wall centerline is to be offset $12"$ from the center of the footing. The top of wall elevation

on one end of the wall is designed to be elevation ${55}^{\text{'}}$ and slopes to elevation $51\mathrm{.}5\text{'}$ at the

opposite end of the wall. The wall length is $64\text{'}$ long. What is the volume of concrete

required for the wall placement assuming $7\%$ waste? We will be pumping the concrete and

will need to prime the pump $($assume $1\mathrm{.}5$ cy $),$ and we will be pulling $8$ wheelbarrows of

concrete measuring $8$ cu ft each for concrete testing.

$2$A$)$ Sketch the cross section of the wall and footing on the provided graph paper,

show all dimensions and elevations

$2$B$)$ Sketch the side view of the wall and footing on the provided graph paper, show

all dimensions and elevations

$2$C$)$ Provide calculations on a separate piece of provided graph paper of the

concrete quantity to be ordered.
