Schnabel was the first firm in the Mid-Atlantic focused on geotechnical engineering for soil and foundation concerns. Since then we’ve grown to include construction support, geostructual design, geosciences, environmental engineering, infrastructure monitoring, mine tailings design, and risk management. Our geoprofessionals engage in these diverse services with our clients on projects that positively impact people and the environment.

Innovation is a trademark of our firm and we’re proud to have been at the forefront in advancing new concepts and methodologies throughout our history. Schnabel is a pioneer in the use of technology and foundation systems as illustrated by these examples:

  • First to use the Menard pressuremeter extensively in the U.S.
  • First to recommend the use of double under-reamed drilled shafts in the U.S. for heavy structures.
  • First to recommend the use of floating stone columns in the U.S.
  • First to recommend the use of a geosynthetic-reinforced stone safety mat for structures in karst.
  • Early use of Limited Mobility Grouting to support shallow foundations in karst
  • First to use Pile Driving Analyzer testing for Quality Assurance of Micropiles in karst

Schnabel has been recognized for significant achievement by many entities such as the American Council of Engineering Companies, American Society of Civil Engineers, Transportation Boards, Deep Foundation Institute, ENR MidAtlantic, and Office of Surface Mining Reclamation and Enforcement for our geoprofessional contribution to award-winning projects. These awards include contributions in innovative foundation design, geostructural design solutions, and a deep understanding of designing complex infrastructure projects. Notable projects include Yeager Airport Runway 5, Charleston, West Virginia; Route 29 Solutions, Charlottesville and Albemarle Counties, Virginia; Children’s Hospital of Richmond Pavilion at VCU, Richmond, Virginia; and Mid-Lothian Mines Park, Midlothian, Virginia.
