C. DAILY FIELD REPORT Page 1 of 1 Project Name: Foothill Sanitary Landfill - Area 2A Report Number: 026 Project Number: 11-101-01 Date: Tuesday 06/16/15 Owner: Dept. of Public Works, San Joaquin County CQA Monitors: T. Sathees Contractor: R J Gordon Construction, Inc. M. Hug and Weather: Clear Wind: 0-10 mph. Temperature: ARprox. range 70-100 F Other: The contractor worked from 7:00 am to 5:30 pm. Excavation: Up to (1) CAT D6, (1) CAT D8 and up to (4) CAT 627 scrapers continued excavating Drainage Basin 2 at southeast of the project area and hauled the material to the South Stockpile 3. After 3:30 pm the excavation activity was stopped. (1) CAT 621 water pull was used to maintain excavation areas. (1) Hitachi 300 excavator was used to remove and trim the soil at high spots at slopes along north and northwest side of the cell. One laborer assisted the process with a shovel. (1) CAT 14H motorgrader and (1) CAT D6 dozer part time trimmed the upper slopes along east side of the cell. South Stockpile 1 (Foundation): The scrapers stockpiled few loads of fine-grained materials hauled from the excavation at Drainage Basin 2. (2) CAT 637 scrapers continued hauling the Foundation soil, from 7:00 am to 3:30 pm, to placement area at the cell. South Stockpile 2 (Operations): No activity was observed. South Stockpile 3: The scrapers hauled and stockpile the soil from the excavation at Drainage Basin 2 at Southeast of the project area. (1) CAT 621 water pull was used to maintain the stockpile and haul roads. Access Road Embankment Fill (Earthfill): No activity was observed. Foundation Layer: Foundation layer was placed today at Northwest area of the cell floor. (1) CAT 825 compactor prepared the subgrade prior to placement of the Foundation layer soil. (2) CAT 637 scrapers hauled the soil from South Stockpile 1 (Foundation) and placed thin lifts. The 825 compactor and a vibratory -type CAT CS54B smooth -drum roller (from afternoon) were used to break the big clods and to compact the Foundation soil. (1) CAT 14H motorgrader was used for spreading and mixing the soil. (1) CAT 621 water pull was used to moisture -condition the subgrade and Foundation soil. At 3:30 pm hauling activity (scrapers) was stopped as to provide more time for the processing effort to break down clods at the fill by smooth drum roller, motorgrader and the compactor only. The Contractor also utilized the scraper traffic, which were hauling and stockpiling the material from excavation areas to provide additional processing and compaction to the Foundation layer at Southwest portion placed yesterday (where a 6 to 7 - inch thick compacted layer was achieved). Three locations at Southwest floor area were examined in order to evaluate the effectiveness of the processing -effort to help assist the Contractor. It was found that the approximately 6-12 % of the material had clods sizes of 1 to 2 inches, with scattered plus 2 -inch size clods. Two samples were obtained, and the fines content was 39% for both samples. All soil passed through 3/8" sieve. Density testing on the Foundation layer indicated compliance with the specifications. Equipment Onsite: (1) CAT D8T dozer, (1) CAT D6T dozer, (1) CAT D6R dozer (with slope board) (1) CAT 621G water pull, (4) CAT 627 scrapers, (2) CAT 637 scrapers, (1) 14H motorgrader, (1) CAT 825H compactor, (1) water truck, (1) Hitachi 300 excavator, (1) CAT CS 54B smooth drum roller (vibratory type).
