WMU D-99 Construction September 1999 <br /> Forward Landfill Job No.986011.02 <br /> 2.0 PROJECT CONSTRUCTION SUMMARY <br /> Construction components of the project consisted of earthworks and geosynthetics <br /> tasks. The earthwork tasks included subgrade excavation and fill operations, <br /> foundation layer placement, preparation (admixing) of the clay liner material and <br /> placement of clay liner(WMU D-99), installation of a granular leachate collection and <br /> removal system (LCRS), and placement of protective operations layer. The <br /> geosynthetics tasks included installing the GCL, the 60-mil high-density polyethylene <br /> (HDPE) geomembrane, gecomposite, and geotextile. <br /> The earthworks tasks described above were conducted by Guinn Construction (Guinn) <br /> and Forward personnel. Direct supervision of the construction crews was provided by <br /> Duane Meadows and Robert Burns of Guinn. Installation of the geosynthetic <br /> components was performed by GSE. Direct supervision of the geosynthetics crews <br /> was provided by Bill Gerry of GSE. <br /> The excavation, fill, and subgrade preparation conducted by Guinn and Forward was <br /> initiated on or about May 10, 1999. Stockpiling and mixing of the clay liner material <br /> began on June 1, 1999 and was completed on June 2, 1999. Placement of the clay <br /> liner by Guinn began on June 14, 1999 and was completed by June 24, 1999. GSE <br /> began deployment of the geosynthetic materials within WMU D-99 on June 30, 1999 <br /> with completion on July 22, 1999. Earthwork and subgrade preparation for the <br /> Leachate Impoundment was not completed until August 12, 1999 which necessitated <br /> GSE to demobilize from the site and return at a later date. Deployment of the <br /> geosynthetic materials on the Leachate Impoundment began on August 16, 1999 with <br /> final completion on August 30, 1999. <br /> The composite liner system for WMU D-99, the Eastern Ash Pit Closure, and the <br /> Class II Leachate Impoundment at the Forward Landfill is complete and was installed in <br /> general accordance with the plans and specifications and CQA manual. <br /> Vector Engineering, Inc. - 12438 Loma Rica Dr.,#C - Grass Valley, CA- (530)272-2448 <br /> -4- <br />
