DAILY FIELD REPORT Page 1 of 1 <br />Project Name: Foothill Sanitary Landfill - Area 2A Report Number: 08S <br />Project Number: 14-101-01 Date: Tuesday 09/8/15 <br />Owner: Dept. of Public Works, San Joaquin County CQA Monitors: R. Nogales <br />Contractor: R J Gordon Construction, Inc. M. Hu and <br />Weather: Clear - Hot Wind: 0-15 mph. <br />Temperature: Approx. range 56- 99 F Other: <br />The contractor worked from 5:30 am to 6:00 pm. <br />Operations Layer Processing: Contractor continued screening of operations stockpile today at 6:00 am. (1) Hyundai 480L <br />excavator, (1) CAT D6 dozer (1) 950 M Loader used to perform screening operations. The Hyundai 480L used to load soil <br />from the West end of Stockpile 2 into the Power Screen screening plant. Screened product was stockpiled in a cone using a <br />belt stacker to keep the screened soil separate from unprocessed soil. (1) 950 M Loader was used to relocate +1" from under <br />belt into separate stockpile. (1) Sample was collected from today's stacker belt stockpile for a full gradation in field lab. Lab <br />results indicated 100 % Passing 1" Screen. Screening operation ended at 6:00 pm. <br />Operations Layer Placement: (1) Hitachi 300 loaded (1) Cat 745 Dump Truck with Screened Operations Layer for <br />placement on cell floor. (1) D6 LGP and (1) D4 Dozer were used to spread Operations layer 2 ft thick over deployed 8 oz/sy <br />geotextile along Western most portion of cell working to the north and west. Random samples of Operations layer were hand <br />sieved in field with 1" screen during placement. Placement discontinued at 6:00 pm <br />Gravel Drainage Material Placement: 19-20 various types of end -dumps were used to import Gravel Drainage Material <br />(GDM) from the Cemex Rock Plant until 4:30 pm. Observed trucks operating on at least 3 ft of GDM overlying the <br />Geomembrane. (1) CAT D6 LGP dozer equipped with GPS spread GDM in the center of cell floor pushing north and west this <br />morning beginning at 5:30 am. (1) CAT D6 LGP dozer equipped with GPS spread previously stockpiled GDM along toe of the <br />Northern slope. (1) Laborer controlled wrinkles. GDM placement discontinued at approximately 11:30 pm due to moderate <br />to heavy wrinkles observed in HDPE Liner. GDM import continued, with material stockpiled on graded Operations Layer <br />along Eastern portion of floor adjacent sump. AES QA personnel monitored the placement and verified the depths of the <br />placed LCRS gravel by using a dulled probe. (1) GDM sample was collected at 10:30 am. Field gradation indicates GDM met <br />the required specifications. <br />Geotextile: RJ Gordon deployed and Great Basin sewed 8 oz/sy geotextile over GDM along Western portion of the cell floor. <br />(2-3) Laborers were used to hand roll Geotextile into place. (1) Laborer Observed using hand sewing machine to sew seams. <br />Geocomposite: 8oz Geotextile seams were sewn by Great Basin using hand sewing machine along sides of previously <br />deployed Geocomposite on the Northern Slope. Observed 3ft overlap and nylon ties secured 6 -inch intervals along existing <br />Area 1 geocomposite at the Tie-in to North. A 8oz Geotextile Cap placed over nylon ties and heat bonded to existing <br />Geocomposite. <br />Leachate Collection Pipe: Contractor installed portions of Middle and Northern Leachate Collection, Pipe. Approximately <br />100 if of 6" perforated HDPE pipe was placed today. (1) John Deere 410 Backhoe and (1) Cat 950 M Loader operating over <br />completed operations layer soil was used to place coarse gravel over 6" Perforated HDPE Pipe. Coarse gravel and 6" HDPE <br />pipe was wrapped in 8 oz/sy Geotextile. Gravel was measured to be a minimum 1 ft deep and a minimum 4 ft wide. Geotextile <br />was measured to have a 2 ft minimum overlap. <br />24" HDPE Riser Pipe and Sump: No activity observed today <br />Equipment Onsite: (1) CAT D6T LGP dozer, (2) water trucks, (1) Hitachi 300 excavator, (1) CAT TH160B folk lift, (1) John <br />Deere 410 Backhoe. (1) CAT 623 paddlewheel scraper. (1) Power Screen, (1) Belt Stacker, (1) Hyundai 48OLC excavator, (1) <br />CAT D6T dozer, (2) Cat 745 Dump Truck, (1) Cat 950 M Loader (1) CAT D4 Dozer <br />Problems/Resolutions. <br />Visitors: M.
