Geotechnical and environmental geophysical investigations employ non-destructive techniques to image areas of interest.  These projects require the right equipment, experience, and approach.

Geophysical Approach to Problems

  •  Define the project goal. Be specific.
    • What is the source of the problem?
    • What is the target of the survey?
  •  Define the geological and cultural environment.
    • What physical properties of the target contrast with the environment it is in?
  •  Determine which geophysical techniques should be used.
    • What geophysical techniques take advantage of the contrast in physical properties?
    • Which techniques are most cost-effective?
  •  Understand the limitations of the techniques and what the finished product will look like.
    • Who is doing the interpretation?
    • How detailed will the interpretation be?
    • Is the project feasible and when will this be known?
  •  Determine the logistics of the project, including constraints of weather and terrain.
  •  Determine what complimentary studies are necessary or recommended.
  •  Determine the time required to do the project and the project deadlines.
  •  Decide on the desired reports and deliverables.
