C DAILY FIELD REPORT Page 1 of 1 Project Name: Foothill Sanitary Landfill - Area 2A Report Number: 010 Project Number: 11-101-01 Date: Friday 05/22/15 Owner: Dept. of Public Works, San Joaquin County CQA Monitors: T. Sathees Contractor: R J Gordon Construction, Inc. Weather: Partly cloudy Wind: 0-10 mph. Temperature: A22rox. range 50-75 F Other: The contractor worked from 7:00 am to 4:00 pm. Excavation: 7:00 am to 4:00 pm. Up to (2) CAT D6 (one was delivered today with slope board attachment) and (1) CAT D8 dozers with ripper attachments assisted up to (4) CAT 627 and (2) CAT 637 scrapers load material from the excavation along north side of the cell. The soil was hauled and stockpiled at North West Stockpile for use as daily cover for active landfill operations and at South Stockpile 2 for use as Operations layer soil. Some soil was hauled for liner subgrade Earthfill construction along south side of the Cell. The soil was hauled on an approximate 5 -min cycle. (1) CAT 14H motorgrader and (1) CAT D6 dozer with slope board attachment trimmed the upper slopes along north side of the cell. North West Stockpile: 7:00 am to 4:00 pm. (1) CAT 14H motorgrader was observed spreading and grading the soil in the stockpile fill area and maintaining haul roads. (1) CAT 621 water pull was used to maintain haul roads. South Stockpile 1 (Foundation): No activity was observed. South Stockpile 2 (Operations): 7:00 am to 9:30 am. (2) CAT 627 scrapers hauled the sandy materials from upper slopes along north side of the cell and stockpiled for use as Operations layer soil. One composite sample was obtained, and the fines content was tested as 24 % of the portion finer that 3/8 -inch. The Contractor stopped stockpiling activity at mid-morning as hard material was encountered with larger clods size. (1) CAT 14H motorgrader was observed spreading and grading the soil in the stockpile fill area and maintaining haul roads. (1) CAT 621 water pull was used to maintain haul roads. Access Road Embankment Fill (Earthfill): No activity was observed. Liner Subgrade Earthfill along South side of the Cell: 7:00 pm to 4:00 pm. (1) CAT 621 water pull moisture -conditioned the Earthfill. (1) CAT 825 compactor was used to break the big clods and to compact the Earthfill. (2) CAT 627 and (2) CAT 637 scrapers hauled the material from the excavation areas and placed Earthfill. As large soil clods appeared and the fill was dry, the Contractor was advised by AES to apply more compaction effort along with more water application before placing additional fill. The Contractor then diverted the CAT scrapers to North West stockpile. Density testing on the Earthfill 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, (5) CAT 627 scrapers, (3) CAT 637 scrapers, (1) 14H motorgrader, (1) CAT 825H compactor Problems/Resolutions.
