a tumn city min4 <br />662 CROMWELL AVENUE <br />ST PAUL MN 55114 <br />PHONE 612,6453601 <br />OBSERVATIONS Of PILE INSTALLATION <br />LABORATORY No. 4220 89-638 <br />January 16, 1989 <br />3 <br />We were informed on January 16, 1989, that pile /36 was mislocated. Using this pile, the <br />capacity of the pile will increase 7 to 8 kips (3 to 4 tons) due to ec^.entric loads. We <br />have reviewed the driving log for this monitored pile, which shows final driving <br />resistances in excess of 40 bpf. In our opinion, pile 136 is capable of supporting a <br />total working load capacity of up to 35 tons, which is in excess of the actual load to be <br />exerted on this pile. <br />It should be recognized that Twin City Testing Corporation does not practice in the field <br />of surveying. Therefore, we must rely on the positioning of pile locations by others. <br />If the construction is redesigned or otherwise moved subsequent to our work, we should be <br />informed so our engineers can assess if additional engineering is required, or to suggest <br />sound engineering alternatives. <br />If you have any questions or comments regarding the contents of this report, or if we can <br />be of further assistance to you, please contact me at 641-9426. <br />TWIN CITY TESTING CORPORATION <br />J�i0'ij6�l. <br />Iha Khilfeh, C.E. <br />plomeo 0! ! � <br />Michael P McCarthy, P.E. <br />Manager, Construction Services <br />Geotechnical Department <br />IKIMPM/ r j r <br />N IO <br />A MUTUAL •/TSCTwM To CL1@Wg .
