FEB 14 '02 05:32PM BRAUN INTERTEC Drywall Supply, Inc, BBXX- 02 -010A January 29, 2002 Page 10 P.14/24 C.6.b. Comments with Regard to Pavement Life and Performance. With the type of materials encountered on this site, we anticipate that fill induced differential ground movements and long term differential settlements will occur through out much of the site as the underlying organic materials continue to consolidate over time. For this reason. differential movements are expected in areas covered by concrete and bituminous pavements such that a higher than normal amount of pavement cracking will occur. We anticipate that costs related to pavement maintenance may also be higher than normal. C.7. Additional Ceotechnical Evaluations This preliminary geotechnieal evaluation should not be used for final design or construction. The information contained herein is provided to help formulate proposed building and foundation types and design concepts. Additional borings and geotechnical evaluations are recommended to evaluate specific building locations, foundation designs and concepts, and to provide the necessary soil and foundation design parameters, analysis and geotechnical recommendations. D. Field Procedures D.l. Subsurface Exploration Methods The penetration test borings were performed on January 16, 2002, with a truck mounted core and auger drill. This machine was equipped with hollow -stem auger. The borings were performed in accordance with ASTM Test Method D 1586, "Penetration Test and Split -Barrel Sampling of Soils." Using this method, each bore hole was advanced with the hollow -stein auger to the desired test depth. Then, a 140 -pound !milliner falling 30 inches drove a standard, 2 -inch OD, split - barrel sampler a total penetration of 1 1/2 feet below the bottom of the bore hole. The blows for the last foot of penetration (BPF), which are an index of soil strength characteristics, were recorded and are shown on the respective logs. Soil samples were taken at 2 1/2- or 5 -foot intervals. The actual intervals and corresponding depths are shown on the Log of Boring sheets.
