(CAI) has been sub -contracted by O'Dell Engineering to provide geotechnical <br />engineering support services for the San Joaquin Regional Rail Commission. <br />Prior to drilling, an Engineer or geologist will mark the boring locations and call 811 to identify utilities. <br />Three (3) geotechnical soil boring will be constructed for subsurface soil exploration. The boring will be <br />advanced using a Truck or Track mounted drill rig with solid -stem or hollow -stem auger, and/or rotary <br />wash drilling methods. Each drilled boring will be a vertical geotechnical boring, diameter ranges from 4- <br />8 inches. <br />The soils samples will be transported by car and preserved in containers with caps wrapped with tape or <br />Ziploc seal bags. Soil cutting will be haul offsite. Boring will be grouted using cement mixture, and the <br />upper feet will be backfilled with soil cutting to match original surface conditions. <br />At the completion of each exploration, the holes will be backfilled per San Joaquin County well and <br />boring permit and capped with either concrete dyed black (in asphalt areas), or native materials (in <br />unpaved areas). At completion, the work area will be cleaned up and returned to its previous condition. <br />Crawfgrd �. <br />6 Associates.
