The role of a Geotechnical Field Technician is vital in the construction and development of infrastructure. Their job is to collect data about soil and rock conditions through field tests, surveys and analysis. This data is then used to determine the stability of the foundation of a building or structure and the surrounding area.

Poorly identified soil or rock conditions can lead to costly structural failures and potential safety hazards. Furthermore, it can result in substantial loss of time and money if unexpected soil or rock conditions are encountered during the construction process. Therefore, the accuracy and detail of the data collected by a Geotechnical Field Technician is paramount in ensuring a successful project outcome.
