He played a key role in facilitating the transfer of legacy environmental liabilities in a project involving multiple industrial sites around the U.S. to a third party.


Mr. Black has worked on a wide variety of geo-engineering projects around the world, including for the foundation designs for multiple interstate-level highway bridges, large buildings, major hydro-electric dam sites, reservoir sites, small and very large slope stability problems, pipeline, electric transmission-line and highway corridors, and tunnels. He has worked on these projects in England, Colombia, Costa Rica, Guatemala, Honduras, N. Ireland, Republic of Ireland, Venezuela, and the US.
