.� <br /> changes may have been gradual, and if t6e changes occuacd between sample intervals, they were <br /> inferred. <br /> Test Pit Procedures <br /> An independent excavating company worldng uader subconttact to our firm cxcavated the test <br /> pits i:sing a rubber-tired backhoe. An engineaing geologist from our fum continuously observed t6e <br /> test pit excavations, logged the subsutfacc condiHons, and obtained representative soil samples. TLe <br /> samples were stored in moisture tight containers and hansported to our labotawry for further visuel <br /> classification and testing. After we logged each test pit, the operator bacldilled each with excavated <br /> soils tamped into place. Some settiement of the bacldll should be expe.cted over time. <br /> 1'he enclosed test pit logs indicate the vertical sequence of soils and materials encountered in <br /> each test pit, based primarily on our field classiScations and supported by our subsequent laboratory <br /> testing. Where a soil contact was observed to be gadadonal or undulating, our loga indicate the <br /> average contact depth. We estimated the relative density and consistency of in situ soils by means of <br /> the excavation characteristics and by the sidewall stability. Our logs also indicate the xpproximate <br /> depths of any sidewall caving or groundwater seepage observed in the test pits,as well as all sample <br /> numbers and sampling]ocations. <br /> � <br /> ; <br /> ; <br /> i <br /> ; <br /> ; <br /> i <br /> �, i <br />
