THE FOLLOWING WAS NOTED:
AESI was onsite today at 1:30pm to continue testing sewer trench backfill south of the building between SSMH 3 and 5. While on-
site, we met with Jerry Jr. with Continental Dirt Contractors (CDC) and discussed work being done today and planned work. The
sewer trench backfill had been completed prior to our arrival. CDC was installing a shallow storm line at the north end of the site
this afternoon.
On-site Sewer Line Trench Backfill SSMH 3 to 5:
AESI used a nuclear, density-moisture gauge to test the new section of sewer backfill. Part of the trench is located in the future
onsite road with most of the trench located in landscaping, as shown on Figure 1 below. We observed that the surface for much of the trench backfill was tire-rutted, surface-cracked and yielding under vehicles. We were able to penetrate 2-1/2 feet deep with a ½
inch diameter, steel soil probe. A compaction test showed less than 90 percent compaction. We discussed the soft area with Jerry,
and he planned to work on it later when they come back across the area with the water main.

FIELD REPORT
On-site Storm Line Trench Backfill SD 9 to SD11:
CDC was installing shallow storm East and South of Storm Drain (SD) 9 as shown on the Figure 2 plan. The sandy soil was 11-15
percent moisture content and test results were less than 95% compaction. We informed CDC and determined to retest the surface of the storm trench next week. The eastern and southern portions of the storm trench will be in future sidewalk and paving. The
storm pipe and backfill south of SD 9 was not completed prior to CDC finishing for the day.
