ATternatIvft ] - <br />This Is ths most positivs foundation solution, would result <br />In the best building performance, and could be carried out at any <br />time. <br />The house and garage may be supported on driven piles that <br />transmit the structural loads down Into the competent Inorganic <br />Oes Moines clayey glacial till below the overlying loose sand and <br />4wamp deposits. If this alternative Is selected the floor slabe <br />should be structural slabs, also supported on piles. <br />Class B timber pi lee treated with creosote, conforming to <br />UBC or ASTM standards for trsated piles would be suitable for <br />this site. The piles should be Installed to achieve at least 20* <br />of embedment Into the competent Des Moines clayey glacial till, <br />below the overlying loose sand and compressible swamp deposits. <br />At our test hole locatlone piles of approximately 30’ to 45’ <br />length, measured from present grade, would be required. In <br />general, the shorter pile length could be utilized within the <br />northwest portion of the presently proposed building location; <br />the longer piles will be required within the south and east <br />portions of the building area.
