Proposal for Geotechnical Services and Phase I ESA <br /> Orange County Jail Site <br /> Hillsborough,Orange County,North Carolina <br /> ECS Proposal Number 06:17061 <br /> If fill material is encountered,the boring(s) should be extended through the fill into firm natural soils; <br /> and therefore, additional cost should be anticipated (not included in this proposal). We have <br /> assumed that the site can be accessed with an ATV drill rig. The boreholes will be checked for <br /> groundwater upon completion of drilling, and then backfilled by shoveling the soil cuttings into <br /> the holes, some settling may occur over time. Depending on the weather, soil and site <br /> conditions, ground disturbance (ruts, tire tracks, etc.) must be anticipated during this exploration <br /> program. This is normal for driving a large ATV-mounted drill rig over a site and, that ECS or <br /> ECS's subcontractors are not responsible to restore the ground surface to its original condition. <br /> If ground restoration is required, it will be invoiced at an additional rate of $160/hour. Based on <br /> the existing site conditions, modifications to our proposed boring locations should be anticipated in <br /> the field. <br /> Upon completion of the field exploration, the soil samples will be returned to the laboratory and <br /> visually classified in general accordance with the Unified Soil Classification System and <br /> selected samples will be tested for moisture content and index testing in accordance with ASTM <br /> Standards. <br /> Engineering Report <br /> The conditions encountered by the borings and the results of the laboratory testing will be <br /> evaluated by a geotechnical engineer and recommendations for design and construction of the <br /> project will be developed. The engineering report will include the following items, if appropriate <br /> for this site: <br /> • Project description; <br /> • Site conditions, including geologic, and special site features; <br /> • Field exploration and the laboratory testing procedures; <br /> • Subsurface conditions; <br /> • Foundation recommendations; <br /> ■ Allowable bearing pressures; <br /> ■ Settlement estimates (total and differential); <br /> • Site development recommendations; <br /> • Suitability of soils for use as fill material; <br /> • Discussion of groundwater impact; <br /> • Techniques to control shallow groundwater; <br /> • Discussion of difficult excavation; <br /> • Compaction recommendations; <br /> • Special conditions encountered; <br /> • Site Seismic classification; <br /> • Site vicinity map; <br /> • Boring location plan; <br /> • Soil test boring logs; and <br /> • Summary of laboratory test results. <br /> Phase I Environmental Site Assessment (ESA) <br /> The Phase I ESA will be prepared in general accordance with ASTM Standard E 1527-05, <br /> Standard Practice for Phase I Environmental Site Assessments.
