DAILY FIELD REPORT Page 1 of 1 <br />Project Name: Foothill Sanitary Landfill - Area 2A Report Number: 030 <br />Project Number: 11-101-01 Date: Monday 06/22/15 <br />Owner: Dept. of Public Works, San Joaquin County CQA Monitors: T. Sathees <br />Contractor: R J Gordon Construction, Inc. M. Hu and <br />Weather: Clear Wind: 0-10 mph. <br />Tem erature: Approx. range 70-100 F Other: <br />The contractor worked from 7:00 am to 5:30 pm. <br />Excavation: Up to (1) CAT D8 dozer and up to (2) CAT 637 scrapers continued excavating Drainage Basin 2 at southeast of <br />the project area and southeast slope area, and hauled the material to the South Stockpile 3. After 3:30 pm the excavation <br />activity at Drainage Basin 2 was stopped. <br />Up to (2) CAT D6 dozers and up to (2) CAT 627 scrapers continued excavating Drainage Basin 1 at northwest of the project <br />area, and hauled, from 7:00 am to 5:30 pm, the brown silty sand material (fine-grained) to the South Stockpile 1 (Foundation) <br />in order to use for Foundation layer construction. <br />(1) CAT 621 water pull was used to maintain excavation areas. <br />Two laborers with shovels and rakes continued working on the north slopes to fine grade the slope face. <br />South Stockpile 1 (Foundation): (2) CAT 627 scrapers continued hauling the Foundation soil, from 7:00 am to 3:30 pm, to <br />placement area at the cell. (2) CAT 627 scrapers hauled the brown silty sand material (fine-grained) from Drainage Basin 1 <br />and stockpiled. (1) CAT 621 water pull was used to maintain the stockpile, and haul roads. <br />South Stockpile 2 (Operations): No activity was observed. <br />South Stockpile 3: The scrapers hauled and stockpile the soil from the excavation at Drainage Basin 2 at Southeast of the <br />project area. (1) CAT 621 water pull was used to maintain the stockpile, and haul roads. <br />Access Road Embankment Fill (Earthfill): No activity was observed. <br />Foundation Layer: The Contractor continued placing Foundation layer at Northeast to Southeast area of the cell floor. (1) <br />CAT 825 compactor compacted the Foundation layer prior to placement of new material. (2) CAT 627 scrapers hauled the soil <br />from South Stockpile 1 (Foundation) and placed thin lifts. The 825 compactor and a vibratory -type CAT CS54B smooth -drum <br />roller were used to break the big clods and to compact the Foundation soil. (1) CAT 14H motorgrader was used for spreading <br />and mixing the soil. (1) CAT 621 water pull was used to moisture -condition the Foundation soil. At 3:30 pm hauling activity <br />(scrapers) was stopped as to provide more time for processing to break down clods with smooth drum roller, motorgrader <br />and the compactor. <br />The Contractor also utilized the scraper traffic, which were hauling and stockpiling the material from excavation areas, to <br />provide additional processing and compaction to the Foundation layer at Northwest to Southwest area that was placed <br />Thursday, 06-18-15 (where approximately 12 -inch thick compacted layer was achieved). Two locations were examined in <br />order to evaluate the effectiveness of the processing -effort to help assist the Contractor. It was found that approximately 3.0 <br />to 3.2 % of the material had clods sizes of 1 to 2 inches, with scattered plus 2 -inch size clods. Two samples were obtained, and <br />the fines content were 36.8 and 39.4 %. All material passed through 3/8" sieve. Density testing on the Foundation layer soil <br />indicated compliance with the specifications. <br />Equipment Onsite: (1) CAT D8T dozer, (1) CAT D6T dozer, (1) CAT D6R dozer (with slope board) (1) CAT 621G water pull, <br />(4) CAT 627 scrapers, (2) CAT 637 scrapers, (1) 14H motorgrader, (1) CAT 825H compactor, (1) water truck, (1) Hitachi 300 <br />excavator, (1) CAT CS 54B smooth drum roller (vibratory type). <br />Problems/Resolutions. <br />Visitors: M.
