Changes at a manufacturing facility will result in replacement equipment being installed on an existing concrete pad (separate foundation). The pad is 2 m by 4 m in plan area and is supported near floor slab level directly on the surface of soil for which drained shear tests indicate a cohesion of 25 kPa and an angle of internal friction of 22°. A representative soil unit weight is 17 kN/m3. The soil rigidity index is 30. The groundwater table is very deep. Determine the maximum weight that the pad foundation should carry, applying the extended bearing capacity equation with a factor of safety of 3.
