Tcst pits were dug to depths of 5.0 to 6.0 <br /> feet below lhe existing ground surface utilizing a hack mounted excavetor supplied by the client; <br /> however, the investigation took plece during the clearing and stripping of the site such that the <br /> observcd layer thicknesses are subject to change. Test pits were positioned with the aid of the <br /> client who was present et the site during the investigation. 'Ihe test pits wtrc located by means of <br /> nortnal pacing procedures and are presumed to be accurate to within a few fcet. During the fieid <br /> work, our geotechnical engineer logged lhe soil and groundwater conditions encountered and <br /> obtained samples from the test pits from ropresentative soil strata The samples were clessifiod <br /> in the field in acwrdence with the Unified Soil Classification Systetn, identified eccording to test <br /> pit number and depth, placed in plastic bags to protect ogainst moisturc loss and ttansported to <br /> the laboratory fortesting. <br /> In addition, we conducted dynamic cone penetrometer tests at 2 Iceations. A Wildcat dynamic <br /> cone penetrometer was used to determine bearing capaciry of the soils. 'Ihe tests wero conducted <br /> to depths of 7 to 8 fcet et thc locations shown on the site plan. Blow counts were recorded for 10 <br /> centimeter increments as a thirty five pound weight was dropped a distance of 15 inches. 'Ihe <br /> blow counts were then converted to standerd penetration blow counls (N-velues), consistency <br /> descriptions, and bearing capaciry in pounds per squere foot (psn. See the bearing capacity <br /> section below for further detnils. <br /> Generally, the test pits and penetrometer tesis were conducted at the same location end therefore <br /> shure the same numbering. <br /> 4-1 ��/� <br />
