Female Agronomist Taking Notes In The Field

Understanding Geotechnical Investigations

If you are planning to purchase or develop a property, a home or something on a commercial basis, conducting a geotechnical investigation is a wise decision. It is a smart way to study the physical properties of soil and rock for identifying potential construction problems. You can always count on Fisher Engineering Limited to provide you with reliable geotechnical investigation services.


We have been providing environmental consultancy services in the real estate industry for over 30 years. Our team of experienced professionals is trained to complete any environmental project, regardless of the scope and location.


Why Are Geotechnical Investigations Needed?

Geotechnical investigations are performed by geologists and geotechnical engineers to get information about the physical characteristics of soil and rocks at construction sites. It is very important in designing foundations for structures. A geotechnical investigation comprises of surface and subsurface exploration, soil mechanics, soil testing and subsurface testing.


What Happens in a Geotechnical Investigation?

A geotechnical investigation will consist of two phases. First, a geologist or geotechnical engineer executes a surface evaluation. This may include a site walk, review of aerial photographs and maps, or geophysical surveys. The second phase, which involves soil sampling, is mostly executed by using a drill rig to conduct test borings. This is very important to collect valuable data related to stratigraphy and soil properties.

In boring tests, samples are usually collected for further laboratory examinations. The geotechnical engineer will use the results of the test to assess site suitability for final design recommendations.


Modern Tools of Geotechnical Investigations

The technology involved in geotechnical investigations has progressed a lot over the years with the development of various engineering disciplines. Few of these are mentioned below:

  • Ground-penetrating radar that utilizes radar pulses is used in investigations for subsurface imaging. It is a non-destructive technique that makes use of the reflected electromagnetic radiations from the subsurface structures to compile data.
  • Antennas are utilized for transmission and receiving of signals. Transmission antenna can emit high-frequency pulses into the soil. The waves will strike at objects that have unlike dielectric constants and the data collected can be analyzed for variations detected in the return signal.
