DAILY FIELD REPORT Page 1 of 1 Project Name: Foothill Sanitary Landfill - Area 2A Report Number: 045 Page 2 Project Number: 14-101-01 Date: Monday 07/13/15 Owner: Dept. of Public Works, San Joaquin County CQA Monitors: Jude Contractor: R J Gordon Construction, Inc. M. Hu and Weather: Clear Wind: 0-10 mph. Temperature: Approx. range 70- 92 F Other: At approximately 8: 30 am the construction of the test pad requested by Geosyntec began. The contractor chose to build the pad on the foundation floor in the SW corner of the floor. A CAT 14H motorgrader began by brushing off the surface which was dry, (due to sitting over the weekend.) One laborer picked 3 rocks from the surface of the subgrade. The surface was then rolled and cross rolled using a CAT CS 54B smooth drum roller. The liner contractor then set out GSE GCL panels to cover an area of approximately 20 ft by 50 ft. The GSE GCL was not a roll from this job, but had similar properties and was acceptable per the procedures memo. A 50 foot long by 22.5 wide piece of GSE HDPE DST from this job was then placed over the GCL. A CAT D6 LGP dozer was then used to push the adjacent stockpile of 5/16 LCRS Gravel Drainage Material from Cemex on to the liner as a normal operation would do. The lift was spread in a 9" layer per plans and specs, checked by GPS and also with a probe. The material was tracked 20 times using the CAT D6 dozer. Up to 2 laborers and various pieces of equipment were used to remove the Gravel from the HDPE liner, including shoveling by hand, the Cat 14H blade and the CAT 320 excavator. After the entire sheet of liner was cleaned off, the Geosyntec engineer performed a visual examination of the liner and cut a sample for archive. The operation was over at 2 noon. No perforations or other damage was noted. Geosyntec representative Krzysztof Jesionek was present and in charge of the operation. The test pad was also observed by the County including Taj, Joyesh, Awni and others. The activity was also observed by AES QA Monitor M Huggard.
