Inspector's Notes
Today' s activities listed for CDB at the Defoor site:
Observation and soil density testing on common borrow placed over SF-55 and SF-20 Geogrid Reinforcing from
stations 11+75 to 15+95.
Performed Soil density testing at above locations as per T310 using a nuclear density gauge model 3440 and a
standard proctor value of 116.9 @ 12.8% optimum moisture. The test meets 95% required compaction on fill and
Contractor was informed of test results. See attached Field Density Report for results and locations.
This common borrow used was being transported by Truck from on site stockpiles.
The samples obtained from these nuclear density tests were done per Method 1 SOP 615 and the percent
compaction determined per SOP 615.
While the Geogrid Reinforcing was being installed from stations 11+75 to 15+95 prior to fill the following was
verified:
1. Checked to assure that the proper type of Geogrid reinforcing was being used and was not damaged.
2. Checked to assure the minimum embedment depth was attained according to approved plans&specs
3. Checked that Geogrid was attached together subcontractor using twist ties placing with 1' to2' spacing and
overlapping Geogrid 2to6 inches.
4. A total of 3 rolls of SF-20 Geogrid Reinforcing was layed today.
5. That fill being placed did not exceed 1' subcontractor using a laser to check elevations on each lift.
6. That Geogrid was laying flat and not bundled up prior to fill.
Approximately 1500 cubic yards of material was placed today.
Observed the two 350P offroad dump trucks driving over the compacted material throughout the day with no
deflection or yielding in the material.
The CTI subcontractor only placed a total of 1 1/2 - 1' lifts of fill today
