GEOTECHNICAL

SCI offers clients the advantage of having a single point of contact for a wide range of Geotechnical Services including field explorations, laboratory testing and foundation and site development recommendations. Our geotechnical engineers have extensive experience with varied subsurface conditions encountered all across the country. In addition to owning our own specialized drilling equipment, by contracting with multiple drilling partners, SCI can mobilize several rigs to any site to expedite the exploration phase of projects.

SCI’s geotechnical engineers are also trained to respond to a wide range of emergency situation soil-related issues including:

  • Failure Analysis and Corrective Action Recommendations
  • Soil Stabilization, Slopes and Sinkholes
  • Retaining Walls and Foundations
  • Streambank Instability/Collapse
  • Dams and Levees
  • Post-Earthquake Stabilization (Liquefaction)

GEOPHYSICAL SERVICES

With today’s advanced geophysical imaging technologies, engineers have much more information available to them about subsurface conditions than they previously had through traditional boring and test pitting. These innovative and generally non-invasive techniques enhance SCI’s geotechnical services. They provide additional data for analysis and evaluation and, in many cases, save time and money. Geophysical imaging techniques can be used independently or in conjunction with other methods to provide supplemental information for a wide range of projects.

SCI Senior Geophysicist Dr. Neil Anderson states, “What tool is the most effective in a particular situation depends on quite a few variables. We need to consider what the ultimate deliverable will be; what the immediate environment looks like; the size, depth, and physical properties of the target; and so forth.”

For example, several geophysical technologies have practical applications for transportation departments and are being used for many exploratory activities, such as:

  • Inspecting bridge decks and pavements
  • Identifying deteriorating rebar in concrete
  • Locating underground utilities
  • Mapping the top of groundwater or bedrock
  • Finding subsurface voids

LABORATORY TESTING SERVICES

SCI’s laboratories in Missouri and Illinois are overseen by a Corporate Quality Assurance Manager. The laboratories staff seven full-time and eight part-time engineering technicians and are validated by the USACE and AASHTO accredited.
