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.
Water Line Trench Backfill:
Prior to our arrival Fury backfilled for water line trench (Fig 1). We were informed that pipe was bedded and covered in
sand prior to backfill. We were informed that backfill was approximately 2.5’ thick comprised of imported gravelly sand
with some silt. We were informed that 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).
AESI departed the site in the PM and will return upon request.
*Minimum 95% compaction required for passing result
