Mr.. Chad M. Smilley, IIE, BS11 Life Structures Preliminary Geotechnical Engineering Investigation Proposalfior Proposed Development at Ignition Park, South Bend, Indiana September 21, 2011 Page 2 of J 2. IUPPS- the state utility locator service will be notified to mark existing underground utilities within the public areas. We request that you provide a site plan indicating the location of any site - specific underground structures and utilities. While we will take all reasonable precautions to avoid damaging existing facilities, we cannot assume any liability for disruption of services caused by break in utility lines not adequately marked on a site map or in the field. Existing underground utilities may be marked by a private utility locator service for an additional fee, The subsurface soil and groundwater conditions at the proposed site will be investigated by drilling twelve (12) borings to a depth of 25 ft below the present ground surface in the proposed building area, as requested. Based on the above drilling schedules, the project will involve 300 lineal ft of drilling. No hard drilling through buried concrete, obstructions or rock coring is considered in this proposal. While these depths are generally adequate for the type of construction and loading mentioned earlier, it is possible that the depths may need to be revised due to poor subsurface conditions. In such instance, we will contact you prior to any additional field drilling. 4. From each boring, split -spoon samples will be obtained at intervals of 2'/z ft and 5 ft intervals for laboratory analysis. Standard Penetration Tests (SPT) values will be recorded for each split spoon samples. All borings will be performed in accordance with the applicable ASTM standards. Groundwater observations will be made during and immediately after the drilling. 5. All holes will be back filled with the auger cuttings after the drilling. It is not possible to pack the soil back in the drill holes upon completion so tight that there will be no subsequent subsidence. This proposal does not include repair costs for landscape damage. 6. This proposal does not include assessment or remediation of any environmental conditions present at the site. If apparently impacted materials are encountered during the field testing operation, the drilling will be stopped until the proper course of action is determined. 7. Our investigation will include basic laboratory classification tests on representative soil samples to understand the strength, compressibility and other engineering characteristics of the subsurface materials encountered in the test borings. 8, The results of our field exploration and laboratory tests will be utilized in the formulation of preliminary recommendations and will be presented in a written report signed by a registered professional engineer. As mentioned, additional soil borings will be necessary to develop final geotechnical recommendations once the project layout is complete. [1M�.
