C C DAILY FIELD REPORT Page 1 of 1 Project Name: Foothill Sanitary Landfill - Area 2A Report Number: 032 Project Number: 11-101-01 Date: Wednesday 06/24/15 Owner: Dept. of Public Works, San Joaquin County CQA Monitors: T. Sathees Contractor: R J Gordon Construction, Inc. M. Hu and Weather: Clear Wind: 0-10 mph. Tem erature: ARprox. range 70-100 F Other: The contractor worked from 7:00 am to 5:30 pm. Excavation: Up to (1) CAT D8 dozer, (1) CAT D6 dozer, (2) CAT 637 scrapers and (2) CAT 627 scrapers continued excavating Drainage Basin 2 at southeastern portion of the project area and from the southeast slope area. The material was hauled to the South Stockpile 3. After 3:30 pm the excavation activity at Drainage Basin 2 was stopped. (1) CAT D6 dozer grade the slopes at Access Road at Northwest of the cell. (1) CAT 621 water pull was used to maintain excavation areas, haul roads and stockpiles. South Stockpile 1 (Foundation): No activity was observed. South Stockpile 2 (Operations): No activity was observed. South Stockpile 3: The scrapers hauled and stockpiled the soil from the excavation at Drainage Basin 2. Access Road Embankment Fill (Earthfill): No activity was observed. Subgrade Earthfill: No activity was observed. Foundation Layer: The Contractor continued placing Foundation layer at Northeast to South east and along east toe of the floor. (1) CAT 825 compactor compacted the Foundation layer prior to placement of new material. (2) CAT 627 scrapers hauled the fine-grained soil from the designated borrow area, located southwest of Drainage Basin 2 and placed thin lifts. The 825 compactor and a vibratory -type CAT CS54B smooth -drum roller 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 Foundation soil. At 3:30 pm hauling activity (scrapers) was stopped as to provide more time for processing to break down clods with smooth drum roller, motorgrader and the compactor. The Contractor also utilized the scraper traffic to provide additional processing and compaction to the Foundation layer at floor area. Two locations were examined at the east half of the floor area in order to evaluate the effectiveness of the processing -effort to help assist the Contractor. It was found that approximately 5.6 to 8.2 % of the material had clods sizes of 1 to 2 inches, with scattered plus 2 -inch size clods. The Contractor was advised to provide more processing effort at SE portion where tests showed considerable amounts of clods. Two samples were obtained, and the fines content were 38.4 and 41.7 %. All material passed through 3/8" sieve. Density testing on the Foundation layer soil 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).
