DAILY FIELD REPORT Page 1 of 1 Project Name: Foothill Sanitary Landfill - Area 2A Report Number: 077 Project Number: 14-101-01 Date: Wednesday 08/26/15 Owner: Dept. of Public Works, San Joaquin County CQA Monitors: R. Nogales Contractor: R I Gordon Construction, Inc. M. Hu and Weather: Clear - Hot Wind: 0-10 mph. Temperature: Approx. range 61- 100 F Other: The contractor worked from 5:00 am to 4:30 pm. Operations Layer Processing: Contractor screening operation ran for approximately 1 hour. Screening operation shut down around 7:30-8:00 and did not start back up for rest of day. (1) Hitachi 300 excavator, (1) CAT D6 dozer (1) 950 M Loader was used to perform screening operations. The Hitachi 300 was used to load soil from the western end of Stockpile 2 into the Power Screen screening plant. Screened product was stockpiled in a cone using a belt stacker to keep the screened soil separate from unprocessed soil. Operations Layer Placement: (1) Hyundai 300 loaded (2) Cat 745 Dump Truck with Screened Operations Layer for placement on cell floor. (1) D6 LGP Dozer was used to spread Operations layer 2 ft thick over deployed 8 oz/sy geotextile along middle of cell working to the north and west. After Screening plant shut down a second D6 Cat LGP Dozer was added to operations layer. Random samples of Operations layer were hand sieved in field with 1" screen during placement. Observed 100% passing 1" screen. (1) Sample collected from cell floor. Full gradation was performed in field lab. Lab results indicated 100 % Passing 1" Screen. Placement discontinued at 2:30 pm Gravel Drainage Material Placement: 19-20 various types of end -dumps were used to import Gravel Drainage Material (GDM) from the Cemex Rock Plant until 4:30 pm. Observed trucks operating on at least 3 ft of GDM overlying the Geomembrane. (1) CAT D6 LGP dozer equipped with GPS spread GDM in the center of cell floor pushing north and west this morning beginning at 5:00 am. (1) Laborer controlled wrinkles. GDM placement discontinued at approximately 11:30 pm due to moderate to heavy wrinkles observed in HDPE Liner. GDM import continued, with material stockpiled onto previously deployed GDM. Stockpiling was supported by the Cat D6 LGP Dozer and Cat D4 Dozer. AES QA personnel monitored the placement and verified the depths of the placed LCRS gravel by using a dulled probe. (1) GDM sample was collected at 9:30 am. Field gradation indicated the GDM met the specifications. Geotextile: Great Basin deployed and sewed 8 oz/sy geotextile along Northeastern and middle portion of the cell. (6) Laborers were used to hand roll Geotextile into place. Observed seams sewn using hand sewing machine. Geocomposite: Geocomposite deployed on middle of the eastern slope progressing northward. Observed nylon ties secured at 3 foot intervals along length and 6 -inch intervals along width. Geotextile seams were sewn using hand sewing machine. Installation resulted in horizontal seams on the slope. Horizontal seams are being used on alternate runs down the slope, with single panels extending to the floor on both sides. Leachate Collection Pipe: Contractor installed portions of Northern Leachate Collection Pipe. Approximately 150 if of 6" perforated HDPE pipe was placed today. (1) John Deere 410 Backhoe and (1) Cat 950 M Loader operating over completed operations layer soil was used to place coarse gravel over 6" Perforated HDPE Pipe. Coarse gravel and 6" HDPE 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 was measured to have a 2 ft minimum overlap. 24" HDPE Riser Pipe: No activity observed today. Equipment Onsite: (1) CAT D6T LGP dozer, (2) water trucks, (1) Hitachi 300 excavator, (1) CAT TH160B folk lift, (1) John Deere 410 Backhoe. (1) CAT 623 paddlewheel scraper. (1) Power Screen, (1) Belt Stacker, (1) Hyundai 480LC excavator, (1) CAT D6T dozer, (2) Cat 745 Dump Truck, (1) Cat 950 M Loader (1) CAT D4 Dozer Problems/Resolutions. Visitors: Reviewed By: M.
