The Geophysics Division at Olson offers a wide range of geophysical methods for investigating subsurface conditions – geologic or manmade. The Division is staffed by advanced degree geophysicists, engineering geophysicists and geologists with extensive domestic and international field experience.
Geophysics is generally used in collaboration with other geologic or geotechnical (or environmental) site data to provide details between, below, and beyond existing drill hole data.
The list below represents the primary methods used to help you meet your project objectives. Other less-common methods can be used for specific applications.
Using these six primary geophysical methods, subsurface imaging can provide information on:
- Soil and rock properties and variability (laterally and horizontally)
- Liquefaction potential
- Rippability or excavatability of indurated soils and bedrock
- Anomalous subsurface conditions, hazardous or otherwise
- Groundwater conditions
- IBC Site Classification (Vs30)
- Ground improvement needs and quality assurance
- Construction quality control
- Buried obstacles or objects
These methods are commonly applied to real estate transactions, and to aid owners for insurance claims by identifying hidden subsurface features. For more information on any of these methods, including unique or unusual applications, please contact our office. Our responsive staff will provide information regarding the proper application of Geophysics to save you time and money; or deter you from using geophysics if the methods cannot resolve your objective.
