Table summary is a generalization of subsurface conditions at the individual soil boring locations only. They may not <br /> reflect variations in subsurface strata occurring on site between boring locations. The general geologic origin of <br /> retained soil samples is listed on the boring logs. <br /> 2. Measured thickness of the pavement core. <br /> 3. Apparent aggregate base thickness,at time of our fieldwork,by visual inspection only and is not mean to confer <br /> conformance with DOT specifications. <br /> 4. Undocumented fill soils. <br /> GROUNDWATER AND GROUNDWATER CONTROL <br /> Groundwater was observed in the boreholes at depths ranging from approximately 7.0 to 9.5 feet below <br /> the top of pavement at the time of drilling. <br /> Depending upon elevations of underground utilities, groundwater may be an issue during construction. <br /> It should be noted that if excavations are proposed below the groundwater level,the granular nature of <br /> the majority of the on-site soils will likely result in significant volumes of water entering the excavations <br /> unless proper dewatering measures are implemented. Well points embedded into the underlying sands <br /> will likely be the most suitable method for controlling excess water in deeper excavations. If dewatering <br /> is needed during construction, we recommend that the groundwater be maintained a minimum of 2 <br /> feet below the bottom of the excavation. <br /> LABORATORY TEST PROGRAM <br /> Our analysis and recommendations of this report are based upon our interpretation of the standard <br /> penetration test resistance determined while sampling soils, laboratory test results and experience with <br /> similar soils from other sites near the project. The results of such tests are summarized on the boring <br /> logs or attached laboratory test reports. <br /> Page 3 of 7 <br />
