Yes Project No. <br />Permit No. <br />�At the client's request, ESNW Rep was on site to observe and test compaction of remedial excavation backfill <br />Remedial Excavation Backfill <br />While on site Rep observed the contractor placed 4 feet of cement treated native backfill over the floor of the excavation by <br />dozing in 8"-12" lifts and then compacting each lift with a single drum sheep's foot style roller. The contractor informed Rep <br />that they used ten super -sacks of Portland cement powder to treat the backfill used today. Rep took compaction tests over the <br />cement treated backfill but was unable to obtain compaction results over 82% of the maximum dry density due to the high <br />moisture content of the soil. Rep observed that the backfill was compacted solid and it did not yield or pump beneath the <br />weight of the excavator and bulldozer operating in the excavation today. Given this observation and considering the <br />application of cement amendment to the backfill exceeded our expectations and recommendations the backfill is considered <br />to have been adequately amended and compacted. Rep will return to observe and test compaction of the cement treated <br />remediation backfill. Rep observed the remedial excavation was stable in its current configuration and condition. It is <br />recommended that Rep be notified immediately if any changes in the slope conditions are observed. It is the responsibility of <br />the contractor to perform all necessary safety measures in accordance with state and federal regulations. ESNW rep will <br />return daily to observe the condition of the temporarily over -steepened shoring excavation. <br />ESNW Rep will return when requested. <br />Emmett Hartley, G.I.T. <br />ESNW Field Tech— <br />(206) 376-4906 <br />7 ; <br />�w 4= <br />
