amec <br />Earth $ Environmental <br />surface to a depth of 6" to 8". The subgrade was then moisture conditioned using a CAT 773 <br />water tuck (when necessary) and compacted using a 10-ton vibratory smooth drum compactor. <br />The entire surface of the subgrade was compacted with at least 4-passes. These areas were <br />inspected by an AMEC representative and accepted for structural fill placement. <br />E) Overburden to Stockpile: <br />1) VLF <br />Overburden was hauled to the overburden stockpile area east of the east perimeter road near <br />stations A28+00 (+/-) to A36+00 (+/-) from between stations A9+00 (+/-) and A10+75 (+/-), <br />approximately 40 to 100 feet left of centerline. Overburden was hauled using 40-ton haul <br />trucks loaded by a John Deere 850 excavator. <br />Oversize rock within the Phase 5 VLF fill area was removed from fill areas and hauled to the <br />overburden stockpile area east of the east perimeter road near stations A28+00 (+/-) to A36+00 <br />F) Cut to Fill <br />1) VLF <br />Structural fill placement was performed between stations A 17+00 (+/-) and A 19+00 (+/-), <br />approximately 60 to 150 left of centerline. Fill material was hauled from stations A11+00 (+/-) <br />to A12+00 (+/-), 35 to 45 feet left of centerline, using 40-ton articulating haul trucks loaded by <br />a John Deere 850 excavator. The structural fill material was spread in 18" to 24" lifts using a <br />CAT D-8 dozer. Each lift was moisture conditioned using a CAT 773 water truck (when <br />necessary) and compacted using a 10-ton vibratory smooth drum compactor, passing over the <br />entire fill surface at least 4 times (method compaction technique is applicable). <br />Structural fill placement was performed between stations A23+00 (+/-) and A25+00 (+/-), <br />approximately 40 to 75 right of centerline. Fill material was hauled from stations A11+00 (+/-) <br />to A12+00 (+/-), 35 to 45 feet left of centerline, using 40-ton articulating haul trucks loaded by <br />a John Deere 850 excavator. The structural fill material was spread in 18" to 24" lifts using a <br />CAT D-8 dozer. Each lift was moisture conditioned using a CAT 773 water truck (when <br />necessary) and compacted using a 10-ton vibratory smooth drum compactor, passing over the <br />entire fill surface at least 4 times (method compaction technique is applicable). <br />Structural fill placement was performed between stations A32+00 (+/-) and A39+00 (+/-), <br />approximately 0 to 300 left of centerline. The material pushed from the cut between stations <br />A32+00 (+/-) and A39+00 (+/-), approximately 0 to 300 left of centerline. The structural fill <br />material was spread in 18" to 24" lifts using a CAT D-8 dozer, a CAT D-9 dozer, and a CAT <br />D-10 dozer. Each lift was moisture conditioned using a CAT 773 water truck (when necessary) <br />and compacted using a 10-ton vibratory smooth drum compactor, passing over the entire fill <br />surface at least 4 times (method compaction technique is applicable). <br />Structural fill placement was performed between stations F5+00 (+/-) and F10+00 (+/-), <br />approximately 0 to 300 left of centerline. The material pushed from the cut area between <br />stations 175+00 (+/-) and 1710+00 (+/-), approximately 0 to 300 left of centerline. The structural <br />fill material was spread in 18" to 24" lifts using a CAT D-8 dozer. Each lift was moisture <br />conditioned using a CAT 773 water truck (when necessary) and compacted using a 10-ton <br />VLF Weekly Report WE 08.08.09.D.doc
