Observation and soil testing on common borrow placed over SF-20 geogrid reinforcing from stations 11+75 to 15+95 for secondary lift at elevation at 222'. Observation and soil testing on common borrow placed over SF-55 geogrid reinforcing from stations 11+75 to 15+95 on lift at elevation 223'. Performed soil density testing at above locations as per T310 using a nuclear density gauge model number 3440 and a standard proctor value of 113.0 pcf @ 12.6 optimum moisture. The tests met the required compaction on fill and contractor was informed of test results. See attached Field Density Report for results and locations. The common borrow used had previously been transported by conveyor belt from the Rolling Hills site south of Thunder Creek. The following items were verified: 1) Proper type of geogrid reinforcing was used and was not damaged prior to installation. 2) Checked to assure the minimum embedment depth was attained according to approved plans & specifications. 3) Checked that geogrid was attached together, subcontractor was using twist ties placing with 1' to 2' spacing and overlapping geogrid 2" to 6". 4) A total of 49 rolls of SF-55 geogrid placed as primary reinforcment and 3 rolls of SF-20 geogrid placed as secondary reinforcing was layed today. 5) Fill placed did not exceed 1' lifts verified by laser to check elevations each lift. 6) Geogrid was laying flat and not bundled up prior to fill. Foreman on site verified approximately 3025 cubic yards of material was placed today. Observed one 350 offroad dump trucks driving over compacted material throughout the day with no deflection or yielding in the material. The CTI subcontractor placed a total of two full lifts of fill today and one partial lift not completed the previous day. Lifts at elevations of 222, 223, and 224 ft above sea level were compacted and tested. No further testing is required until the next lift at 225 ft above sea level is placed. Lab work was also done including loggin in of grout specimens as well as compressive strength testing of one 7 day aged concrete cylinder. The specimen tested today was above design strength at 7 days with a compressive strength result of 5530 psi. TImothy I.
