A 24x 48 (BxL) mat foundation causes a bearing pressure of 240 kPa. The footing is to be constructed 4 m below the surface. The dry and saturated unit weights of the soil are 17 kN/m³ and 18 kN/m³, respectively. The soil has c'=24 kPa and angle of friction=24°. The groundwater table is observed at the depth of 10 m. Determine the factor of safety by using Vesic's method to calculate ultimate bearing capacity.
