A square footing located on a dense sand is required to carry a dead load of 200 kN and a live load of 300 kN at an eccentricity not to exceed of 10% of the width. The embedment depth is 1 m. Groundwater level is at 1 m below the ground surface. Calculate the size of the footing using CSM for ASD and LRFD. At a depth B/2 below the bottom of the footing, the soil parameters are

Assume the soil above the groundwater level to be saturated and v' = 0.35. Determine the factor of safety of the footing (use the footing size designed according to CSM) using the conventional method.
