Auto Mall Associates E-2976 May 16, 1986 Page 10 The field exploration was continuously monitored by a senior soils technician from our firm who classified the soils encountered, maintained a log of each test pit, obtained representative bulk soil samples and observed pertinent site features. Soils were classified visually in the field according to the Unified Soil Classification System which is presented on Plate 3, Legend. The consistency of the soil was estimated based on the effort required to excavate the soil, the stability of the trench walls and other factors. Logs of the individual test pits are presented on Plates 4 through 7, Test Pit Logs. The final logs represent our interpretations of the field logs and the results of the laboratory examination and test of field samples. The stratification lines on the logs represent the approximate boundary between soil types. In actuality, the transition may be gradual. Representative soil samples were placed in closed containers and returned to our laboratory for further examination and test- ing. Visual classifications were supplemented by index tests such as sieve analyses on representative samples. Moisture determina- tions were performed on all samples. Results of moisture determin- ations, together with classifications, are shown on the test pit logs included in this report. The results of the sieve analyses are illustrated on Plate 8, Grain Size Analyses. LIMITATIONS Our recommendations and conclusions are based on the site materials observed, selective laboratory testing and engineering analyses. The conclusions and recommendations are professional opinions derived in accordance with current standards of practice. No warranty is expressed or implied. The recommendations submitted in this report are based upon the data obtained from the test pits. Soil and groundwater conditions between test pits may vary from those encountered bf the test pits. The nature and extent of variations between test pits may not become evident until construction. If variations then appear, Earth Consultants, Inc. should be allowed to reeval- uate the recommendations of this report prior to proceeding with the construction. Additional Services It is recommended that Earth Consultants, Inc. provide a general review of the final design and specifications to verify that the earthwork and foundation recommendations have been properly interpreted and implemented in the design and in the con- struction specifications.
