A square footing 7 x 7 feet is located 4 feet below the ground surface in a homogeneous deposit of sand with a friction angle of 31° and an undrained shear strength of 0 psf. The soil has a dry unit weight of 110 pcf and a saturated unit weight of 145 pcf with groundwater 12ft below grade. The foundation is subjected to a vertical force Q of 600 kips and a single moment of 90 kip-ft. Calculate the net allowable bearing capacity assuming a factor of safety of 3.0 using the Modified BC method and comment on the adequacy of the design.
