Keynote Presentation: A Tale of a Thriving City and the Deep Foundations
that Support It
Bill Khouri, P.E. | Schnabel Engineering DC
Whether a project is large or small, local experience reigns supreme and continues to be paramount in
geotechnical practice. This is particularly prevalent in the Nation's Capital, where city planners with limited
geotechnical and geologic knowledge and a bold vision created a striking city over 200+ years ago.
Discussion on the underground challenges of working in the District, inclusive of ancient creeks/tributaries,
buried channels, two distinct geologies, aged utilities, metro tunnels, and man-made fills and dredged materials
used to create "new" land and how they lead to the need for deep foundations. We will look at a few iconic
case histories in our nation's capital to see how the geotechnical community rose to the challenges.
