Geotechnical Engineering

  • Subsurface investigations using soil borings, air track probes, water observation wells, and test pits
  • In situ testing of soil strength and compressibility using the pressuremeter, cone penetrometer, dilatometer, and vane shear
  • In situ shear wave testing for seismic site classification
  • Shallow foundation design such as spread footings, footings supported by rammed aggregate piers, and continuous mats
  • Deep foundation design such as piles and drilled shafts, including load testing
  • Lateral earth pressures for below-grade walls.
  • Subdrainage design systems
  • Temporary excavation support systems
  • Pavement design, management, and damage studies
  • Rock excavation and rippability
  • Global and slope stability analysis
  • Ground modification and stabilization
  • Earthen embankment dam design and rehabilitation
  • Retaining wall/earth structure design
  • Stormwater management design recommendations, including in-situ infiltration analyses
  • Soils and concrete laboratory
