Shannon & Wilson was founded in 1954 as a geotechnical engineering firm.  We offer a complete staff of pro­fessional geotechnical engineers, geologists, technicians, and support personnel.  We are adept at developing project scope and planning exploration programs, directing field drilling and sampling operations, completing laboratory test­ing, and performing engineering analysis, all of which result in practical design and construction recommendations.  We incorporate sustainability into our geotechnical design through the reuse of materials and the implementation of well-designed erosion and sedimentation control programs.  Our services include:

  • Geotechnical/geological site characterization, including geophysical, seismic, geologic hazards, and hydrogeologic setting studies
  • Landslide and rock slide investigations
  • Foundation design recommendations
  • Excavations and shoring
  • Dewatering systems
  • Geotechnical instrumentation
  • Sediment and erosion control
  • Surface/subsurface drainage
