b) A 3.X m x 3.X m square foundation is to be founded at a depth of 1.5 m below ground level in medium-dense sand with a bulk unit weight of 19 kN/m³ and a saturated unit weight of 20.X kN/m³. The water table is located 3.6m below ground level. The immediate settlement is to be limited to 25mm. Estimate the allowable load on the foundation using the standard penetration test data presented in Table 3 below and applying the appropriate correction factors.
