The subsurface conditions were explored by drilling 3 bucket-auger borings, to a depth ranging from 6 to 40 feet below ; 48¢41 iexisting grade. The approximate location of the borings, are <* 4 <br />shown on the Boring Location Map, Figure 3, attached.:The 34.J-.; <br />r..,4,99,7 1.field exploration was performed under the supervision' of:.'our i? 9*, :.: .Engineer who maintained a continuous log of the subsurface 69!30, f <br />soils encountered and obtained samples for laboratory testing: 1-i:944 <br />.B-2. Subsurface conditions are summarized on the log of borings: Di**44The soils encountered were classified in general accordance ' -At 4.- <br />with the Unified Soil Classification System (see Key to Logs, <br />Figure B-0). <br />B-3. Drill holes were located in the field by pacing, working from ' '41 <br />known locations on a map. <br />B-4. The following sampling and testing techniques were used to <br />evaluate the subsurface conditions: <br />a. ' Relatively undisturbed samples were obtained using a 3- <br />inch outside diameter California sampler lined with brass <br />rings, each 1 inch long and 2-1/2 inch inside diameter. <br />The brass rings were transferred into a plastic bag and <br />sealed in a plastic tube immediately upon extraction from <br />the borings. <br />b. The corresponding drive energies per foot of penetration <br />(ft-kip/ft) are indicated on the logs.These energies <br />provide a measure of the relative density or consistency <br />Of the materials encountered.The weights of the <br />separate kellys for the bucket auger borings are shown on <br />the Key to Logs, Figure B-0. <br />C.Bulk samples were also obtained. <br />B-5. The soils were classified based on field observations and <br />laboratory tests. <br />B-6. Groundwater was not observed during the investigation of this <br />site. <br />I- %.-1-*.*- ....=-Ill -- <br />- ..- --- --I ---
