Performed observation and soil density testing on fill using common borrow over Miragrid 3XT and SF-55 /Miragrid 3XT Geogrid reinforcing(remainder of used rolls being used in place of SF-20 Secondary Geogrid reinforcing) from stations 10+35 to 14+00. Performed soil density testing at above locations per T310 and SOP 615 (Method 1) using a Troxler nuclear density gauge model 3440. The moisture density relationship value of 115.9 with a 12.4% optimum moisture was used per Mayes Testing lab number T-09082-28. The test met the 95% required compaction. The contractor was informed of test results. See attached Field Density Report and Density Work Sheet for results and locations. While the Geogrid Reinforcing was being installed from stations 10+35 to 14+00 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, with the subcontractor using twist ties placed at a 1' to spacing and overlapping the Geogrid 2 to 6 inches. 4. There was 30 Rolls Miragrid and Miragrid 3XT/SF-55(remainder of the used rolls used in place of SF-20) for Secondary Geogrid reinforcing were placed today. 5. That fill being placed did not exceed 1'. The subcontractor is using a laser to check elevations on each lift. 6. That the Geogrid was laying flat and not bundled up prior to fill being placed. 7. The unused Geogrid was covered with black plastic to protect from the sun. Elevations 217 and 218 were completed from stations 10+35 to 14+00 with installation and inspection of the Primary and Secondary Geogrid reinforcing. At elevation 219 the fill was placed from stations 10+35 to 11+00 and compacted but no Primary Geogrid reinforcing had been placed at this elevation yet. CTI placed a total of 2,117 cubic yards of common borrow 1,742 cubic yards moved by the dozer and 375 cubic yards transported from 15 truck loads. There was 3,432 cubic yards transported from the conveyor belt today from 156 truck loads. Performed observation of the fully loaded 350D offroad dump truck and water truck driving over the compacted areas and material appeared to be firm and unyielding. Visited by Don Robertson the Safety manager with Gary Merlino,Robert Patcheck with CDB, and Chad Webley the Field Eng. with CDB to see the progress of the project. Ken Viren the materials technician with WSDOT performed a soils density test per T310 and obtained a sample per SOP 615. Bob Pyle the compliance inspector with WSDOT visited the site throughout the day. The stockpile of the unsuitable materials which was located on the northeast area of the site was all transported today to the non reinforcing area next to Cedar road from stations 12+00 to 14+00 and covered with plastic. There was a total of 3,075 cubic yards transported today from a total of 123 truck loads. Performed observation while excavation was taking place from stations 15+00 to 15+95 in non reinforcing area where the stockpile of unsuitable materials was located to ensure that the area was free of any organics prior to fill with common borrow. Organics though were encountered while excavating. Roch Player the Engineer with CDB was contacted and visited the site giving his approval,after his inspection of the area including the organics encountered,to go ahead with fill using the common borrow.
