Crow-Western E-2708 August 14, 1985 Page 9 The locations of the test pits were approximately determined by pacing from survey control stakes present on the site. Elevations of test pits were approximately determined by interpolation between plan contours. The locations and elevations of the test pits should be considered accurate only to the degrae implied by the method used. The field exploration was continuously monitored by an engi- neering geologist 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 10, Test pit Logs. The Einal logs represent our interpretations of the fieid 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 he gradual. Representative soil samples were placed in closed containers and returned to our laboratory for Eurther 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 cf the sieve analyses are illustraked on Plates 11 and 12, Grain Size Analyses. LIMITATIONS Our recommendations and conclusions are based on the site materials obser.ved, selective laboratory testing and engineering analyses. The conclusions and recommendations are professional opinions derived in accordance with current standards oE 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 explorations may vary from those encountered. The nature and extent of variations may not become evident until construction. If variations then appear, Earth Consultants, Inc. should be allowed to reevaluate the reconunendations of this report prior to proceeding with the construction. Eanh Consuhants,lnc.
