� I � I APPENDIX A � FIELD EXPLORATIONS AND LABORATORY TESTItJG jFIELD EXPLORATIONS N'e evaluated subsurface soil and ground water conditions within the planned JanSport huildinp ( b�� ad��ancing cieht borings using a track-moumcd drill rig on March �G. 2001. Tlie approxima�c locations of the explorations arc sho��ni on the Site Plan. Figurc?. The espinration locations wcrc estima�ed from e�isting site featurcs using thc site tnpographic map prcparcd hy Reid Middlclon ' and Associates,Inc.that was provided to us by Sierta Construction. The borings w•erc drilled to depths ranging Gom 1 I'/: to 26'/s feet below the ground surfacc f usine hallow-stetn auger drilling techniqucs. Relatively undisturbcd samplcs wcrc obtained from the borings using a 2.4-inch inside-dia�neler split-barrel sampler driven inro thc soil with n 300- pound Bammer free-falling 30 inches. The 300-pound hammer on this drill rig was operated using 1 an automatic hammer. 71�c number of blows required ro drive the sampler the last 12 inches, or other indicatcd distance,is recorded on the boring logs. � The field e�plorations were continuously monitored by a rcprcsentative from our finn who examined and classified the soils encountered, obtained reprcsemative soil samplcs, and obscrved ground water conditions, if encountered. Soils wcre classified in general accordance with the f classification system described in Figurc A-I. A key to the boring log symbols is presented in Fieure A-2. The logs of thc borings are presented in Figurcs A-3 through A-10. The logs are based on our interpretation of the field and laborarory data and indicate the various ripes of soils ' encountered. 'They also indicate the depths at which these soils or their characleristics change, although the change might actually be gradual. If the change occurrcd between satnples in thc ' borin¢s, the depth of the change was interpre!�d. 'i�a lield log for boring B-1 that was drilled in 1998 near the southeast corner of ttie JanSport building is shown in Figure A-11. The borings were backfilled pursuant to the procedures of Washington Departmen[of Ecology. � LABORATORY TESTING General � Soil samp�cs obtained from the exploratiors were transportcd ro our laboratoq�and examined to confirm or modify field classifications, as �vell as to evaluate engineering propenies of the soil. � Representative samples were selected for laboratory testing that consisted of moismre content and densiry detertninations, as well as one consolidation test. The tesis were perfortned in general accordance with test methods of the American Society for Testing and Materials (ASTM) or other � applicable procedures. Visual Classifications IAll soil samples obtained from the explorations were visually classified in the field and/or in our laboratory using a system based on the Unified Soil Classification System (USCS) and ASTM I � I G c o E n g i n c c r s !�-� FileNo. 758q-002.pp.��30\050101 ' "'
