The percolation tests and borings were <br />taken in the general locations as directed by you and as <br />shown on the attached sketch. Surface elevations at the <br />bore holes were referenced to the center line of North Arm <br />Road south of the southeast property corner of Lot 5 with <br />an assumed elevation of 100.0. <br />INVESTIGATION METHODS: <br />The boring and percolation tests were taken on February 17, <br />1977 using a truck-mounted power auger unit. The soil <br />classifications and depth as shown on the attached logs were <br />inferred from the soils brought to the surface by the con­ <br />tinuous flight feature of the auger. The depth of strata <br />change is thus considered approximate. The soils encoun­ <br />tered in the borings were visually and manually classified <br />in accordance with ASTM D2487 ’’Unified Soils Classification <br />System and ASTM D2488 "Recommended Practice for Visual and <br />Manual Description of Soils". A copy o.. ASTM D2487 is <br />attached. Representative samples were then returned to our <br />laboratory for verification of the field classifications by <br />a Soils Engineer. Representative samples will remain in <br />this office for a period of 60 days to be available for your <br />examination. <br />CONSULTING ENGINEERS/SOUS AND MATERlAlS <br />77-045 <br />Brauer 5 <br />The borii <br />to check <br />also reel <br />Absence < <br />borings 1 <br />recheck ( <br />groundwal <br />The perc <br />drilled <br />with pro' <br />Health (1 <br />of Orono <br />and side <br />remove ai <br />soil int< <br />inches o <br />holes to <br />filled w <br />the top ( <br />the perc( <br />insulati< <br />leaving i <br />overnighi <br />RESULTS: <br />The log o <br />water lev <br />Boring sh <br />Boring B- <br />silty san <br />the surfa <br />was then <br />terminati <br />Boring <br />sand t <br />foot d <br />silty <br />sand g <br />to app <br />by a <br />depth
