A 1.5 m x 1.5 m square footing will be constructed on cohesive soil. A centric column load on the footing is 250 kN. A unit weight of soil, (γsoil) is 18.8 kN/m3 where as the unit weight of concrete, (γconcrete) is 23.5 kN/m3. Cohesive soil with unconfined compressive strength, (UCS) is 143.6 kN/m3. Design;

(i) the soil contact pressure.

(ii) the factor of safety against bearing capacity failure.
