For an offshore project, a steel pipe pile with an outside diameter of 18 in. penetrates 150 ft through normally consolidated clays. Soil conditions are as follows: From zero to 50 ft depth, the cohesion is 800 psf and the saturated soil unit weight is 105 pcf; from 50 to 100 ft depth the cohesion is 1,500 psf and the saturated unit weight is 115 pcf; below 100 ft, the cohesion is 2,400 psf and the saturated unit weight is 125 pcf. The water surface is above the soil surface. Using the lambda method, determine the axial capacity of the pile in kips, using a factor of safety of 2.
