Schnabel at a Glance

Small company values ground our business today just as they did when Jim Schnabel started and operated the company out of his parents’ home in Washington, DC, in 1956. As the first true consulting firm in the Mid-Atlantic region to offer both subsurface investigations and soil and foundation engineering consulting services, Schnabel established itself as the “firm of choice” for geotechnical work in the Washington metro area. As we’ve grown over the years to the national firm we are today, that spirit of innovation continues, with numerous firsts and patents reinforcing our reputation in the industry.
