FIGURE $10\mathrm{.}48.$ Building Foundation Plan.FIGURE $10\mathrm{.}53.$ Wall Section$\mathrm{.}1-$ You need to estimate the amount of excavation required for the basement in the figures.

$2-$ You also need to estimate the amount of backfill required to be place in the excavation

after the footing and the wall hare poured.

The specifications indicate the following:

The soil has a swell factor of $25\%.$

The soil has a shrinkage factor of $97\%.$

A $4-$foot working distance is required.

The excavation will be sloped $2$:$1.$

$3-$ You need to estimate the cost of the excavation in one above using the following

information:

Required equipment $-$ Backhoe with a $1\mathrm{.}5$ cubic yard bucket.

Mobilization $-3$ hours

Productivity of the backhoe $-75$ LCY per hour

Equipment cost $-$ $$76\mathrm{.}50$ per hour

Operator cost $-$ $$36\mathrm{.}25$ per hour

Solve question $1,2$ and $3$ and show all work. There are other example on chegg with the same figure just different questions. Make sure to answer all $3$ questions.
