Notes: * - Fb = Ultimate End Bearing Pressure (unfactored) for long piles, Fs = Ultimate Shaft Adhesion (unfactored).




The upper 1 m of soil profile should be ignored in shaft calculations to allow for shrinkage
cracks. The values presented in Table 3 assume that the material equal to four pile diameters
below the base of any footings is as strong or stronger.


Settlement values are subjected to a variety of factors; however, a properly designed and
constructed pile should have a serviceability settlement between 1% and 2% of its’ diameter.
