The project consists of the expansion of the Industrial Landfill IV located within the Y-12 Nuclear Security Complex in Oak Ridge Tennessee. The expansion included excavation of soils to design lines and grades, screening of excavated soil to provide material for a compacted clay liner, placement of the compacted clay liner, installation of geosynthetic layers of the liner system, installation of leachate collection system, and placement of protective cover soil.
GEOServices performed Construction Quality Assurance (CQA) services for the construction activities related to Area 2 – Phase II Expansion of the ILF-IV facility in Oak Ridge, Tennessee. Testing and observations were completed as described in the Quality Assurance Plan for the expansion. During performance, GEOServices evaluated documentation of the manufacturer’s materials certification; obtained conformance sample results for geosynthetic materials, soil, and aggregates; and performed field observations of the liner installation including field testing and verification of installation methods, and laboratory testing of geomembrane weld samples.
