Geotechnical Engineering & Design

Our team of skilled and knowledgeable geotechnical professionals conduct geotechnical studies to help understand the application of geology, soil mechanics, hydraulics and strength of materials in all phases of the design and construction process. Our experience in geology, forensic engineering and geotechnical engineering provides the basis for professional judgments that result in reliable, sustainable products and solutions. Our support services include:

Subsurface Investigation

Drilling in Black Hawk 2-smaller

To facilitate the success of a project, we work to understand the subsurface distribution of soil and rock materials, groundwater, their engineering properties and their interaction with project elements by employing the following means, when and where appropriate, to conduct subsurface studies:

  • Auger borings
  • Odex
  • Rotary drilling
  • Rock coring
  • Continuous sampling
  • Limited access
  • Exploratory pits or trench excavation and mapping
  • Sampling (i.e. modified California, split spoon and Shelby tubes)
  • Instrument installations (i.e. inclinometers, piezometers)
