Geotechnical Engineering - Civil and Geotechnical Engineering
 Geotechnical engineers at Summit Consulting have performed subsurface investigations and geotechnical evaluations for a large number of commercial, institutional, industrial and residential buildings, communication towers, and transportation structures. Our senior geotechnical engineers Don Dewey, PE and Andrew Nash, PE have more than 30 years experience providing geotechnical engineering services in North Carolina. Our highly trained geotechnical engineers have extensive knowledge of local soil conditions, shallow and deep foundation systems, pavement design, site preparation, and earthwork specifications.

Geotechnical investigation is critical to any successful construction project. Construction of any new structure requires an understanding of how the new construction will interact with subsurface materials. The geotechnical engineering firm must understand the local geology and soil conditions, typical construction practices, and anticipate problems germane to the area. The correct firm must be selected to provide efficient site preparation and foundation design alternatives.

Summit provides the following Geotechnical Engineering Services:
  • Subsurface Field Investigations
  • Foundation Analysis and Design Recommendations
  • Pavement Design Recommendations
  • Settlement Rate/Magnitude Evaluation
  • Earthwork and Site Preparation Recommendations
  • Groundwater Control and Dewatering Systems
  • Earth Retaining Structure Design Criteria
  • Slope Stability Analysis and Slope Stabilization
  • Subgrade Stabilization – Geosynthetics
  • Laboratory Testing
  • Phase I Environmental Site Assessments
