These <br />values incorporate a safety factor of 1.5 and include the dead weight of the pier; as such, <br />they represent groundline uplift capacities. A linear interpolation may be used between <br />each depth interval to obtain the allowable capacity for specific depths not shown. <br />TABLE 3 <br />RECOMMENDED ALLOWABLE UPLIFT CAPACITIES (TdNS) <br />Tip Depth Drilled Pier Diameter (feet) <br />(feetl <br />4 5 6 7 8 <br />10 6 9 12 16 20 <br />15 12 17 22 29 36 <br />20 19 26 34 43 53 <br />25 27 37 48 60 74 <br />30 37 50 64 80 97 <br />35 49 65 83 103 124 <br />40 62 82 105 129 155 <br />' Lateral Resistance: Drilled pier foundations for communication towers are typically rigid <br />and act as a pole which rotates around a fixed point at depth.
