No groundwater was encountei:ed in the other test pits. <br /> In addition, the test pit excavated _�djacent to the northwest <br /> building corner encouritered a nine i �ch pocket oE wood chips <br /> approximately three to four feet belaw the footing elevation. <br /> We anticipate that the fills beneakh this site extencl fifteen <br /> (15) to twenty ( 20) feet below existing ;rades and are c,..nposed of � <br /> relatively clean, medium dense to Jense, fine sands. Aeneath the <br /> fill, five feet to twenty ( 20) feet of moderately compressible soil � <br /> � may be pre.�ent. <br /> DISCUSSZON AND RECOMMENDATIONS <br /> Based on soils encountered in our test pits, and our geotechnical <br /> analysis, it is our opinion that the structure may be built as <br /> planned. Probing in the footing areas indicated that the allowable <br /> bearing pressure of two thousand (2000 ) pounds per square foot (psE) <br /> used in design of the footings is apNropriate. However, we do <br /> recommend that all footings be tied together into a continuous 9rid. <br /> We recommend that, in addition to perimeter footing drains, at � <br /> least two lateral drains be placed within the crawlspace area. All <br /> drains, both perimeter and lateral should be placed at least one foot <br /> below the bottom of the footings. The drains should be located a <br /> horizontal distance away from the footings equal to or greater than I <br /> the depth of the drains. These drains should be provided with a pea <br /> gravel filter and should have a positive gradient towards suitable <br /> discharge facilities. <br /> Soils removed from the footing/crawlspace area should not be <br /> replaced in the buil9ing area. In addition, no new fills should be <br /> placed adjacent to the building area. <br /> Settlements due to the placement of the hydraulic fi11s should <br /> have stabi3ized by this time and settlements due to the weight oE the <br /> structure should be wi�hin tolerable limits. iPe do recommend that <br /> survey points be established on each cornec of the structure and <br /> should be checked as construction progre�ses. If settlements are <br /> measured on the building, we should be provided with the data Eor � <br /> analysis. <br /> M <br /> 1 <br /> I� <br /> Earth Consultants, Inc. <br /> I. � � <br /> I <br /> 1 <br />
