Deep Foundations Institute (DFI) announces Mary Ellen Large has been named co-chair of DFI’s Structural Slurry Wall and Seepage Control Committee. She succeeds Amr Ragy of Bauer Foundation Corp. and joins co-chair Meeok Kim, Ph.D., P.E., of Thornton Tomasetti.
Large brings over 30 years of foundation experience to geotechnical specialty engineering and construction contractor, Nicholson Construction Company, headquartered in Pittsburgh, Pa. As client care manager, she strengthens relationships with current clients and develops new relationships and partnerships across several markets.
She is a professional engineer in Pennsylvania, New York and Michigan; a member of ADSC, ASCE, Chi Epsilon, DFI, Engineers Without Borders, TRB, USSD, and ASDSO; and a diplomate of geotechnical engineering.

She holds a bachelor’s degree in civil engineering from the University of Maryland and a master’s degree in geotechnical engineering from Cornell University.
The Structural Slurry Wall and Seepage Control Committee was formed when DFI’s Seepage Control Committee and Slurry Wall Committee merged at the start of 2023. The mission of the committee is to be a collaborative forum to discuss and disseminate best practices for structural slurry walls and seepage control, and to advance the awareness, use and performance of structural slurry wall and seepage control technologies.
Ryan Reavis has joined the institute as the technical activities manager. In this role he will work in concert with DFI’s director of technical activities supporting DFI’s committees, publications and outside industry partners and ensuring that DFI’s technical activities are coordinated, scheduled and supported to produce high-quality, accurate and relevant industry products.
“Ryan is a results-driven individual with a passion for connecting with new and previous colleagues,” says Matthew Glisson, P.E., director of technical activities at DFI. “His many years of construction experience in our industry as an employee of DFI member companies makes him well suited to support DFI committees.”
Reavis is an experienced professional with over 20 years in the geotechnical industry. He held various leadership positions, including project manager with Keller, operations manager for McKinney Drilling Company, project development manager for rail at GeoStabilization International and operations manager for Eclipse Foundation Group. His diverse experience in construction project operations, management, logistics and contracts has equipped him with a unique skill set for his current role.
