THE FOLLOWING WAS NOTED:
Water Line:
AESI was onsite at 1:30pm and observed Continental Dirt Contractors (CDC) finishing installation at the western end of the 10-inch
diameter, water line they installed today. CDC bedded the pipe with crushed rock (5/8-inch minus) to approximately 6 inches over the
top of the pipe followed by backfilling with onsite soil. Approximately 2-1/2 to 3 feet of soil backfill was needed to reach surrounding
grade. The onsite soil consisted of gray, silty sand with some gravel to brown, sand with some silt. Several areas were left uncovered
at water valves and where steel plates were temporarily placed over the trench for equipment access. CDC used a vibratory plate
attached to a large excavator to compact the backfill in at least two lifts. The compacted material probed only 1-2 inches with a ½
inch diameter, steel soil probe and was in a firm and unyielding condition. Test results are shown on the table below in Table 1 and
the test locations are shown on Figure 1.
