Zachary Simpson

Zack is an experienced geotechnical engineer who specializes in ground improvement, especially for challenging or complex soft ground sites in seismic regions. Although based in Charleston, Zack’s performance-based modeling experience has him working on many of our most complex projects across the country—from smaller development projects that hit a snag to multi-million-dollar transportation design-builds.

“That’s what I like about GeoEngineers,” Zack says. “We’re not afraid to take on those difficult projects where typical approaches just won’t cut it.”

Zack has contributed to some of GeoEngineers’ largest ground improvement programs, including award-winning designs for Puget Sound Energy’s award-winning LNG plant that included approximately 2,500 36-inch rigid inclusions. In addition to large ground improvement programs, Zack also specializes in seismic analyses and shoring designs for projects requiring deep or complex excavations. Challenging sites are Zack’s favorite, and he is particularly proud of his contributions to the geotechnical design for the U.S. 21 Harbor River Bridge Replacement.

“Our innovative geotechnical design dramatically reduced the foundation and construction costs through the use of multiple ground improvement techniques and an in-depth site characterization program,” Zack explains, “ultimately helping the contractor win the project and keep it on schedule during construction.”

Outside of work, Zack prioritizes time with his family. You might find him at home playing with his kids or relaxing with some video games, TV, or a good movie.
