.].I FIEI,D EXPLORATION PRO(;RAM <br />The field exploration program involved drilling of one hollow-stem auger boring to depth of <br />51.5 feet below existing ground surface. Soil materials encountered were visually classified <br />and logged in accordance with the Unified Soil Classification System. The approximate <br />location ofthe boring is shown on Figure 2. <br />Log ol subsurface conditions encountered in the boring was prepared in the field by an <br />engineer. Soil samples consisting of relatively undisturbed brass ring samples and Standard <br />Penetration Tests (SPT) samples were collected at 5-loot depth intervals and were returned to <br />the laboratory for testing. One bulk sample was collected at depths of I to 5 feet below ground <br />surface (bgs). The SPTs were performed at selected depth in accordance with ASTM D-1586. <br />Final boring log was prepared from the field log and is presented in Appendix A. <br />3,2 LABORATORY TESTING <br />4.0 DISCUSSION OF FINDINGS <br />The following discussion of findings for the site is based on the results of the field exploration <br />and laboratory [esting programs. <br />{.I SITT, AND ST]BSURFACE CONI)ITIoNS <br />Fill material was encountered within our exploratory boring to depth of approximately 3 feet <br />below the existing ground surface. Fill materials consisted of silty sand and sand. Fill soil was <br />found to be medium dense. Native materials were observed beneath the fill uithin our <br />exploratory boring. These materials were observed to be of sandy clay, clay and silty sand. <br />Clayey soils were found firm and stifC Sandy soils were found medium dense. For more <br />detailed descriptions of the subsurface materials refer to the boring logs in Appendix A. <br />2# <br />Selected samples collected during drilling activities were tested in the laboratory to assist in <br />evaluating controlling engineering properties of subsurface materials at the site. Physical tests <br />performed included moisture and density determination, direct shear, No. 200 Wash. Atterberg <br />limits. and corrosion. The results ofthe laboratory testing are presented in Appendix B. <br />Dennis- l -01
