Statement of Qualifications

Mankind lives on the earth. Everything built, either originated from, is built on, or interacts with, the earth. Geology is the science of the earth. Geotechnical Engineering is the application of geology and mathematics to use Earth’s natural resources to build infrastructure. Tierra Group International, Ltd. applies its geotechnical expertise to the conception, design, construction, and operations of physical structures for the mining industry, including:

  • Foundations
  • Tailings Dams
  • Water Dams
  • Heap Leach Pads
  • Mine Pits
  • Waste Rock Dumps
  • Hydraulic Structures (Canals, Channels, Pipelines, etc.)
  • Civil Infrastructure (Plants, Buildings, Roads, Bridges, etc.)

Tierra Group has applied its 100+ years combined professional geological and engineering expertise consulting on, or designing and constructing, dozens of these structures on six continents. This geographic variety has allowed Tierra Group’s Team to develop expertise designing facilities under challenging geotechnical conditions such as:

  • Laterites
  • Saprolites
  • Swelling or Collapsible Soils
  • Karst
  • Variable Geology
  • Highly and Active Seismicity (Earthquakes)
  • High Altitudes (4,000-m amsl)
  • Tropics

Tierra Group has innovatively adapted to these challenging environments using highly-trained professionals and state-of-the-art techniques and software to perform the following tasks and analyses:

  • Site Characterization
  • Soil/Rock Mechanics
  • Geologic Hazards – Landslide, Rock Fall, Avalanches, Seismic (Earthquakes)
  • Geotechnical Analyses – Slope, Stability, Seepage, Settlement, Consolidation, Deformation, Liquefaction
  • Civil Design and Specifications
  • Construction Documents
  • Resident Engineering
  • Quality Assurance
  • Operations Support
  • Forensics and Mitigation
  • Peer Reviews

Regardless of the geotechnical challenges posed, Tierra Group’s broad experience, intimate attention to site-specific conditions, and keen focus on developing innovative solutions, has earned us a respected reputation and loyal clients around the world.
