Lutzky Associates Development, LP - Geotechnical Investigation <br />MACTEC Project 4953-03-2631 <br />September 18,2003 <br />Direct shear tests were performed on selected undisturbed natural samples to determine the <br />strength of the soils. The tests were performed at increased moisture content and at various <br />surcharge pressures. The yield-point values determined from the direct shear tests are presented on <br />Figure A-3, Direct Shear Test Data. <br />Confined consolidation tests were performed on undisturbed samples to determine the <br />compressibility of the soils. Water was added to the samples during the tests to illustrate the effect <br />of moisture on the compressibility. The results of the tests are presented on Figure A-4, <br />Consolidation Test Data. <br />To determine the percentage of fines (percent passing through a No. 200 sieve), tests were <br />performed in selected samples. The results of these tests are presented on the boring logs. <br />The Expansion Index of the soils was determined by testing one sample of the upper soil in <br />accordance with the Uniform Building Code Standard 29-2 method. The results of the test are <br />presented on Figure A-5, Expansion Index Test Data. <br />Hydroconsolidation tests were performed on one undisturbed sample of the upper soils to <br />determine the hydroconsolidation potential of the purous upper natural soils. The results of the <br />tests are presented on Figures A-6, Hydroconsolidation Test Data. <br />The results of prior corrosion testing in the vicinity of the site are attached at the end of this <br />appendix. <br />A-2
