4 <br /> r.. .,10# <br /> specifications to evaluate if the considerations included in this report have <br /> been properly interpreted and implemented in the design and specifications. <br /> The recommendations of this report are based upon the assumption that the <br /> soil and bedrock conditions do not deviate from those disclosed in our subsurface <br /> explorations. If variations from our findings or undesirable conditions are <br /> found during construction, or if the proposed construction differs from that <br /> presently planned, McClelland Consultants should be notified so that supplemental <br /> recommendations can be given. <br /> FIELD INVESTIGATION <br /> Exploratory Soil Borings <br /> Eight (8) soil borings (B-1 through B-8) were drilled between December 5 and <br /> December 7, 1988, under the technical direction of our field geologist. The <br /> boring locations were located and pre-staked by PSE. Offset from the staked <br /> locations were provided to PSE, who resurveyed the as-drilled locations and <br /> surface elevations. These locations are shown on Plate 2. <br /> The borings were advanced using a truck-mounted Failing 1500 drill rig and <br /> two-man crew, which were subcontracted from the Pitcher Drilling Company. The <br /> borings were drilled with a 5-inch wet, rotary drag and rock bit. <br /> The deepest borings, borings 2 and 3, were at the anticipated turbine and <br /> boiler area; these borings were drilled to depths of 50 and 62 ft, respectively. <br /> Borings 1, 4, 5, and 6, all were located within the "plant" area and were drilled <br /> to depths of 30 to 40 ft. Borings 7 and 8 were located in the proposed runoff <br /> containment area south of the "plant" area, and were drilled to 13.5 ft penetra- <br /> tion. <br /> The nearsurfacesample interval was at about 3-ft intervals where soils <br /> predominated. Through depth intervals where glass-filled trenches were encoun- <br /> tered, samples were collected from the drill cuttings. Below about 15-ft depth, <br /> a 5-ft sample interval typically was used. <br /> A 2-3/8-in.-I.D. , 3-in.-O.D. California liner and 1-3/8-in.-I.D. , 2-in.-O.D. <br /> split-barrel Standard Penetration Test (SPT) samples were alternated down to <br /> about 10 and 15-ft penetration. California Liner samples were obtained with a <br /> 140-pound, 30-inch stroke down-hole hammer using a wireline system. SPT samples <br /> were obtained with an above-ground, 140-pound rope-around-the cathead "donut" <br /> 1144A/CC-4 "�McClelland <br />
