Vc"TOR NGINEERING,INC. DAILY CONSTRUCTION FIELD REPORT Project Name: Project No. Daily Field Report Sequence Number: Forward Landfill 2008 021605.08 37 Location of Work: Client Or Manager Date: Day of The Week: Manteca, CA Forward/AWI August 11, 2008 Monday General Contractor: Liner Contractor: Project Engineer: Guinn Comanco Lewis Engineering General Foreman: Liner Superintendent: Other: LaEy Jose Ramirez Source and Description of Fill Material: Weather: CQA Technician: On-Site light tan clayey soil Warm and breezy Aaron Lickingteller Equipment on site: 815 compactor,tractor with BeGe blade and disc,5 x 637 scrapers, 1 x 627 scraper,2 x water trucks,D-6 dozer,D-6 dozer w/slo e-board,excavator,623 scra er, 16 G Motograder,825 compactor,smooth drum roller,backhoe,2 forklifts NOTES(Describe work completed during the day,any problems and their solutions): - Comanco and Vector personnel inspected and approved the subgrade on the northwest slope prior to deploying geosynthetics. - Guinn watered the completed low permeability soil surface with one water truck. - CQA monitored moisturizing of low permeability soil surface. - Received 21 rolls of 12 oz. geotextile. - After reviewing Comanco's proposed panel deployment layout, the direction of deployment on the 5:1 of the north-western corner was questioned because it created cross seams on the slope along the entire length of each panel at approximately 15 degrees from horizontal every time a panel was deployed. The proposed layout was to be done for all layers. The Comanco superintendent,Jose Ramirez, concurred with the CQA that the present layout would maximize cross seams for this corner of the cell and was told by the Comanco project manager, Graydon Renshaw,that the method was approved verbally by the enginer, Sangeeta Lewis. After contacting the engineer and having been assured verbally by her that the proposed method of panel deployment was allowable, deployment of GCL occurred in the manner specified. All other layers are to follow the same method of placement. - 41,869 square feet of GCL was deployed on the northwest corner. The GCL was deployed in a location and in a manner that would not allow liner to be deployed without at least 50%of each panel being cut to cover the underlying GCL and would not allow continuous seaming to occur for the length of each panel and would have resulted in one portion of each panel being seamed on Monday and the other portion being seamed on the following day. Deploying in this manner would have also risked damaging the liner by folding it back and by having to drag it in the dirt during deployment, as no GCL would have existed beneath it. The GCL was covered with pieces of scrap liner found on site in a scrap pile used in deployment of liner in the previous cell and plastic sheets of visqueen. Tomorrow's areas will display an area deficiency between the GCL and HDPE areas. Prepared By: Reviewed By:RL 4/23/03,Rev.0 1 of 1 C-2
