A $4 \mathrm{~m}$ wide strip footing is founded at a depth of $1.5 \mathrm{~m}$ below the ground surface in a $c-\phi$ soil as shown in the figure. The water table is at a depth of $5.5 \mathrm{~m}$ below ground surface. The soil properties are: $c^{\prime}=35 \mathrm{kN} / \mathrm{m}^{2}, \phi^{\prime}=28.63^{\circ}, \gamma_{\text {sat }}=19 \mathrm{kN} / \mathrm{m}^{3}, \gamma_{\text {bulk }}=17 \mathrm{kN} / \mathrm{m}^{3}$ and $\gamma_{w}=9.81 \mathrm{kN} / \mathrm{m}^{3}$. The values of bearing capacity factors for different $\phi^{\prime}$ are given below.

Using Terzaghi's bearing capacity equation and a factor of safety $F_{s}=2.5,$ the net safe bearing capacity (expressed in $\mathrm{kN} / \mathrm{m}^{2}$ ) for local shear failure of the soil is
