See text for additional discussion. <br /> s Estimated pile tip elevations were chosen based on pile loads provided by MN and applying a factor of safety=1.55 to estimated ultimate capacities. This factor of safety <br /> assumes that pile driving analyzer testing will be used to evaluate pile capacities during driving. In addition,estimated pile tip elevations assume that lateral fixity is achieved <br /> above this elevation. See text for additional discussion. <br /> ° Contigency lengths represent additional length of pile we recommend to be ordered for risk mitigation of uncertain subsurface conditions. <br /> MLLW=mean lower low water <br /> 21-1-21962-003-R2-T1.x1sx 21-1-21962-003 <br />
