Clean soils are defined as granular soils that have a fines content of less than 5 percent (by weight) based on the soil fraction passing the U.S. No.3/4-inch Sicve. CLOSURE The conclusions and recommendations presented in this report arc based, in part, on the explorations that we performed for this study. If variations in subsurface conditions are discovered during earthwork, we may need to modify this report. The future performan.c and integrity of the tower foundations will depend largely on proper initial site preparation, drainage, and construction procedures. Monitoring by experienced gcotechnical personnel should be considered an integral part of the construction process. We are available to provide gcotcchnical engineering services during the earthwork and foundation construction phases of the project. If variations in the subgrade conditions are observed at that time, we would be able to provide additional geotechnical recommendations,thus minimizing delays as the project develops. We are also available to review preliminary plans and specifications before construction begins, and to provide gcotcchnical inspection and testing services during construction. I
