Penetration resistance of the split-barrel <br />sampler!las recorded as "Blows Per Foot" and is shown on the boring logs. <br /> <br />. LABORATORYTFSI'ING' <br /> <br />All samples from the borings were examined and classified in the laboratory by a soils engineer. <br />Laboratory tests were performed on selected soil samples in order to evaluate the engineering <br />properties of the foundation medium in accordance with the prescribed ASTM Standards. All test <br />results are pres~ on Plates 2 through 12. <br /> <br />Atterberg Limits, Percent Passing No. 200 Sieve and Moisture Content tests were performed on <br />typical samples to establish the index properties and to aid in the proper classification of the <br />subsurface materials. <br /> <br />Strength properties of the soils were determined by means of unconfmed compression tests <br />performed on undisturbed samples. <br /> <br />SUBSURFACE CONDmONS <br /> <br />The soils at the site generally consist of fum to very stiff clays. Stiff sandy clays were <br />encountered in Borings B-3. B-4, B-7, B-I0 and B-ll, generally between four (4) and twelve (12) <br />feet. Granular solls such as silty sands and clayey sands, were encountered only 'in BoriQg B-4 <br />between twelve (12) and seventeen (17) feet and between twenty two (22) and twenty five (2S) feet. <br /> <br />The surficial sandy. clay and clay soils are generally medium to highly plastic and are classified as <br />.CL. and IICH" type salls in accordance with the Unified Soil' Classification System. The <br />plasticity index of the soils throughout the site varies between fifteen (IS) and fifty two (52). <br /> <br />Groundwater was only encountered in Boring B-4 at a depth of fifteen (1S) feet below existing <br />grade during drUling. <br /> <br />GROUNDWATER VARIATIONS <br /> <br />The information in this report summarizes conditions as found on the date the boriDgs were drilled. <br />The depth to the static water table may be expected to vary with environmental variadoDS such as <br />freqUeJ,lcy and magnitude of rainfall and the t.ilne of year when coDStrucdon begins. <br /> <br />2 <br />
