Should extending the borings be deemed necessary, <br /> ECS would contact you for authorization. <br /> The boreholes will be checked for groundwater upon completion of drilling, and then backfilled by <br /> shoveling the soil cuttings into the holes. Some settling of backfill in boreholes may occur over time. <br /> ECS is not responsible for returning to the site to re-fill holes which have backfill that settled. <br /> Holes drilled through asphalt or concrete will be patched. <br /> Laboratory Testing <br /> The recovered soil samples will be delivered to ECS' laboratory and visually classified in general <br /> accordance with the Unified Soil Classification System (ASTM D2487 and D2488). Selected SPT samples <br /> may be tested for the following in accordance with the referenced ASTM standards: Natural Moisture <br /> Content(ASTM D2216), Atterberg Limits (ASTM D4318), and Percent Passing the No. 200 Sieve (ASTM <br /> D1140). <br /> Engineering Report <br /> The conditions encountered by the borings and the results of the laboratory testing will be evaluated by <br /> a geotechnical engineer and recommendations for design and construction of the project will be <br /> developed. The engineering report will include the following items: <br /> • Project description; <br /> • Site conditions, including geology, and special site features; <br /> • Field exploration and laboratory testing; <br /> • Subsurface conditions; <br /> • Preliminary Shallow foundation recommendations, if appropriate; <br /> • Allowable bearing pressures; <br /> • Estimated settlement(total and differential); <br /> • Preliminary ground improvement or deep foundation recommendations, if necessary; <br /> • Site Seismic classification; <br /> • Lateral earth pressure recommendations; <br /> • Preliminary floor slab recommendations; <br /> • Permanent site slopes; <br /> • Preliminary 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 /> • Structural fill recommendations; <br /> • Compaction recommendations; <br /> • Special conditions encountered; <br /> • Site vicinity map; <br /> • Boring location plan; <br /> 111 Illlr���rllllllll�ll <br /> f i YfJ Ind /I /I/I/J <br /> rlr , <br />
