In this regard, the Contractor's responsibility includes but is not limited to: overexcavation and subgrade preparation; preparation of the supporting surfaces (generally soil) for the geosynthetic installation; installation of the geosynthetics; and placing earth materials over the installed synthetic systems. The Contractor is further responsible for all activities of Subcontractors including but not limited to the geosynthetics Subcontractor. "Geomembrane" - An essentially impermeable synthetic material used as an integral part of a cover system. It is sometimes referred to as a FML, sheet, or panel. For this project, the geomembrane consists of VFPE. "Geosynthetics" - A generic classification given to synthetic (man-made plastic and fabric) materials used in geotechnical and construction applications. "Included are geomembrane liners, geotextiles, geosynthetic clay liner (GCL), geocomposites, geogrids, geocomposites and geocells. For this project, the term geosynthetics is used to refer to the geomembrane, geocomposite and geotextiles. "Geosynthetic Subcontractor" - The firm, if other than the Prime Contractor, responsible for handling, storing, placing; seaming, and -other aspects +ofthe installation of the geosynthetics included in the cover system.
