A proposed office building will include a $1$ meter by $1$ meter footing. It has a depth

of embedment of $2$ meters. The footing has a net stress increase of $120k\frac{N}{m^2}.$ The

soil layer at the embedment depth is sand with $17k\frac{N}{m^3}$ unit weight. The soil

below this footing is composed of $1$ meter thick well$-$graded sand and its unit

weight is $17\mathrm{.}5k\frac{N}{m}3.$ It is then followed by a $1-$meter thick clay layer with the

following properties: $\frac{C_c}{1+e_0}=0\mathrm{.}10,\frac{C_s}{1+e_0}=0\mathrm{.}022,e_0=0\mathrm{.}75{}_c^{\text{'}}=180k\frac{N}{m^3}$
