Mr. Briggs manages the Civil Engineering group for KEY. He has extensive experience in geotechnical and remedial designs and has developed a practice for managing liability "buy out" programs. Mr. Briggs's expertise in utilizing the latest in geosynthetics for closure of landfills and impoundments led to the development of a patent- pending solution for the management of Coal Combustion Residues (CCR). The Sustainable Habitat approach to the closure of coal ash properties has provided a cost effective and ecologically friendly system that is well received both by the owners, as well as the environmental advocacy groups.
