GEOTECHNICAL ENGINEERING STUDY Inform, Inc May 9, 2002 Laboratory Testing E-8493-5 Page 4 Laboratory tests were conducted on representative soil sarrples to verify or modify the field soil classification and to evaluate the general physical properties and engineering characteristics of the soil encountered. Visual field classifications were supplemented by grain size analyses on representative scil samples. Moisture content tests were perFormed on all samples. The results of lai�oratory tests performed on specific samples are provided either at the appropriate sample depth cn the individual boring logs or on a separate data sheet contained in Appendix B. It �s important to note that these test results may not accurately represent the overall in-situ soil conditions. Our geotechnical recommendations are based on our interpretation of these test results and their use in guiding our engineering judgment. ECI cannot be responsible for the interpretati�n of these data by others. In accordance with our Standard Fee Schedule and General Conditions, the soil samples for this project will be discarded after a period of fifteen (15) days following completion of this report unless we are otherwise directed in writing. DISCUSSION AND RECOMMENDATIONS General Based on the results of our study, it is our opinion the proposed fueling station can be constructed generally as planned. Support for the kiosk and fuel island canopy can be provided using conventional spread and continuous footing found�tion systems bearing on competent native soil or on structural fill. Slab-on-grade floors and pavements can be supported on competent native soil or on at least one foot of structural fill. At our boring locations we encountered up to three feet of inedium dense fill. Existing fill soil may be considered for support of the foundations, or slab, provided the existing fill can be compacted in-place to the requirements of structural fill. If loose fill or native soil is encountered at construction subgrade elevations it should either be overexcavated and replaced with structural fill or compacted in-place to the requirements of structural fill. Alternatively, the footinps may be extended through the loose soil to the underlying compatent native soil. Emlh Cnmullnnte. Inr,.
