We were verbally informed by John, that 6a sed on the test results Titan <br />E ering could decide if [he compaction was sa[isf actory. <br />COPIES TO <br />RE VI EIIED BY <br />This report presents oplnio ns formed as a resuU of our observations of fill placement. We have relied on the contractor to continue applying the recommended compactnre eHOrt and moisture to the fill during <br />times when our observer is not observing operations Tests are made of the fill only as believetl necessary to calibrate our observer's judgement Test data are not the sole ba sus for opinions on whether the <br />fill meets spec~fcation s. <br />(C) <br />• • • <br />
