Four(4)4-inch diameter <br /> � o H exploratory borings were drilled on 2day 7, 1991, to a maximum dep[h of twenry (20)fcet. The <br /> � � � locations of the exploratory borings aze shown on the Site Plan, Figure 2. The soils encoantered <br />! � y , in the boring were continuously logged in the field by our representative. 'Che soils aze <br /> described in accordance with the Unified Soil Classification System (ASTM D-248�. The logs <br /> of the borings (Figures B-1 through B-4 and B-101 through B-107) as well as a key for the <br /> , classification of the soil (Pigure A-i) aze includcd. <br /> The elevations on the boring logs are based on an assumed datum elevation of 100 feet and <br />' , should be used only for comparison between the borings. 'fhe approximate locauons of the <br />'� borings were determined by taping from reference comers and should be wnsideced acwrate <br /> i only to the degree implicd by the method used. <br /> I Representative soil samples were obtained from the exploratory borings at selected depths <br /> � ' appropriate to the soil investigation. Soil samples were obtained using the 2-inch O.D. split- <br /> I I C-� spoon samplec All samples were transmitted to our laboratory for eva(uaGon and appropriate <br />� testing. <br /> 1 �.� Resistance blow counls were obtained with the samplers by dropping a 140-pound hammer <br /> II �..�� through a 30-inch free fall. The sampler was driven 18 inches, or a shorter distance where hard <br /> resistance was encountered, and the number of blows was recorded for each 6 inches of <br /> � penetration. The blows per foot recorded on the boring logs represent the accumulated number <br /> �� � ' of blows that were required to drive die last 12 inches, or the number of inches indicatecl where <br /> � '�''� hazd resistance was encountered. 1liese blow counts aze the standud penetration resistance <br /> I ` values. <br /> � �� 1 The attached boring logs and related information show our interpreta�on of the subsurface <br /> I ' � conditions at the dates and locations indicated,and it is not warranted that they aze representative <br /> ' ' of subsurface conditions at other locauons and times. <br /> ; ����� , � <br /> rt <br /> I <br /> !t�� H <br /> � <br /> � <br /> '� Kaldveer AssoNates <br />
