, Hennepin Parks <br /> Project BABX-91-589 <br /> December 19, 1991 <br /> ' � Page 9 <br /> ' <br /> , . The ower au er borin wer <br /> p g gs e taken with the same equipment in general accordance with <br /> ASTM D 1452, "Soil Investigation and Sampling by Auger Borings." The soil classifications <br /> ' and strata depths were inferred from the cuttings brought to the surface by rotation of the <br /> auger. Samples of the auger cuttings were then sealed in a glass jar. . <br /> ' E.2 Soil Classification <br /> Soils encountered in the borings were visually and manually classified in the tield by the crew <br /> ' chief in accordance with ASTM D 2487, "Classification of Soils for Engineering Purposes," <br /> and ASTM D 2488, "Description and Identification of Soils (Visual-Manual Proc�;dures).° A <br /> 1 summary of ASTM D 2487 is attached. All samples were then returned to our laboratory for <br /> review of the field classifications by a soils engineer. Representative samples will remain in <br /> ' our Minneapolis office for a period of 60 days to be available for your examination. <br /> E.3 Groundwater Observations <br /> ' Immediately after taking the final samples in the bottoms of the standard penetration test <br /> borings, the holes were probed through the hollow-stem auger to check for the presence of <br /> , groundwater. Immediately after withdrawal of the auger, the holes were again probed and the <br /> depths to water or cave-ins were noted. The borings were rechecked and backfilled just prior <br /> to leaving the site. <br /> ' In the ower au er b ri <br /> p g o ngs, the bore holes were probed after withdrawal of the auger and the <br /> ' depths to water �r cave-in were noted. The borings :vere rechecked and backfilled just prior <br /> to leaving the site. <br /> I F. <br /> General Recommendations <br /> ' F.1 Basis of Recommendations <br /> The analyses and recommendations submitted in this report aze based upon the data obtained <br /> ' from the soil borings performed at the locations indicated on the attached sketch. Variations <br /> occur between these borings, the nature and �xtent of which will not become evident until <br /> ' � additional exploration or construction is conducted. A reevaluation of the recommendations of <br /> this report should be made after performing on-site observations during construction and <br /> ' <br /> , <br />
