THE FOLLOWING WAS NOTED:
AESI arrived on site at 9:30am at the request of the contractor to perform compaction tests on the electrical trench backfill.
When we arrived on site, we met Jason for the trench backfill.
Electrical Trench Backfill:
The material was covered by 1 inch of light/fluffy snow. We have been informed by the contractor that failing tests from
field report 73 have not yet been addressed. We performed 5 compaction tests. All tests met the specification
requirement of at least 95% compaction. The contractor has been informed of the results. The results and locations are
shown in Table 1 and Figure 1.
The contractor told us that we will be needed on site in 1 month. During that visit, we will test the southern entrance again.
