THE FOLLOWING WAS NOTED:
Associated Earth Sciences, Inc. (AESI) arrived on site in the PM in order to observe earthwork activities. Upon arrival we
met with Mark and Dan.
Storm Drain Trench Backfill:
While we were onsite we observed Fury backfill for storm drain trench from CB 401 to CB 402 and CB 4 to Private CB 1(Fig
1). Backfill was approximately 3’ thick comprised of imported very gravelly sand with some silt and imported 5/8” minus
crushed rock. Backfill was placed in multiple lifts and compacted utilizing a vibratory ho-pac. AESI completed compaction
tests on the surface and achieved results which meet minimum compaction specifications (Table 1).
Site Fill:
Prior to our arrival the contractor filled for the roadway and the temporary pond (Fig 2). Roadway fill was approximately
1.5’ comprised of imported gravelly sand with some silt. Temporary pond was filled approximately 2’ thick comprised of
imported sand with some gravel. We were informed that fill was placed in 6” thick lifts and compacted utilizing a vibratory
smooth-drummed roller. AESI completed compaction tests on these surfaces and achieved results which meet minimum
compaction specifications (Table 1).
AESI departed the site in the PM and will upon request.
