DAILY FIELD REPORT Page 1 of 1 Project Name: Foothill Sanitary Landfill - Area 2A Report Number: 087 Project Number: 14-101-01 Date: Thursday 09/10/15 Owner: Dept. of Public Works, San Joaquin County CQA Monitors: R. Nogales Contractor: R J Gordon Construction, Inc. M. Hu and Weather: Clear - Hot Wind: 0-15 mph. Temperature: ARprox. range 69- 108 F Other: The contractor worked from 7:00 am to 6:00 pm. Operations Layer Processing: Contractor continued screening of operations stockpile # 3 today at 7:00 am. (1) Hitachi 300 excavator, (1) CAT D6 dozer (1) 950 M Loader used to perform screening operations. The Hitachi 300 used to load soil from Stockpile 3 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. (1) 950 M Loader used relocate +1" from under belt into separate stockpile. (1) Sample collected from the stacker belt. Full gradation was performed in the field lab. Lab results indicated 100% Passing 1" Screen. Screening operation ended at 6:00 pm. Operations Layer Placement: (1) Hyundai 480LC loaded (2) Cat 745 Dump Trucks with Screened Operations Layer for placement on cell floor. (1) D6 LGP and (1) D4 Dozer were used on a part time basis to spread Operations layer 2 ft thick over deployed 8 oz/sy geotextile along western and northern edges of the cell. (1) 14M Motor Grader was used to fine grade operations layer. (1) Random samples of Operations layer were hand sieved in field with 1" screen during placement. Placement discontinued at 3:30 pm. Gravel Drainage Material Placement: Import had been completed. No GDM placement or grading was performed today. Geotextile: Great Basin hand sewed previously deployed 8 oz/sy geotextile along western edge of the cell. Great Basin deployed and sewed 8 oz/sy geotextile over previously placed GDM in the middle portion of sump. (2) Laborers were used to hand roll Geotextile into place. (1) Laborer was observed using hand sewing machine to sew seams. Geocomposite: 8 oz Geotextile seams were sewn by Great Basin using hand sewing machine along sides of previously deployed Geocomposite on the Northern Slope. Observed 3ft overlap and nylon ties placed at 6 -inch intervals along the tie in with Area 1. An 8 oz Geotextile cap was placed over nylon ties and heat bonded to existing Geocomposite. Leachate Collection Pipe: Contractor installed remaining balance of Northern Leachate Collection Pipe. Approximately 45 if of 6" perforated HDPE pipe was placed today. (1) John Deere 410 Backhoe 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. Force Main: (1) Hitachi 300 and (2) Laborers were used to excavate portions of 2 ft wide trench for Force Main and electrical conduit. During excavation Hitachi 300 damaged an active 2" condensate line. The damaged line was repaired immediately. Leak Detection: Leak Location Services Inc. on site today to perform leak location survey. Survey not completed today. 24" HDPE Riser Pipe and Sump: (1) Hitachi 300 was used to hoist 24" Primary Riser pipe back into position. Riser pipe had slid down slope approximately 4' raising the end of pipe 8" off of sump floor. Observed bottom of 24" Riser pipe resting once again on Sump Floor. Coarse Gravel Placement: (1) Cat 950 M Loader used to place coarse gravel into sump and over ends of 24" HDPE Riser Inspection pipes. Addition gravel needed to reach required Coarse gravel grade. Anchor Trench: Great Basin removed sand bags and cut geosynthetics square to back of Eastern Anchor Trench. RJG used (1) Loader and (1) Water truck to moisture condition and place Operation Layer soil in southernmost portion of Anchor Trench. (2) Laborers hand graded operation layer and applied compactive effort using Mechanical Tamper. Field density testing indicated 90% relative com action and +Z- 3% of optimum moisture content was achieved. 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 (1) 14M Motor Grader Problems/Resolutions.
