What is the responsibility of a geotechnical engineer?

The responsibility of a geotechnical engineer primarily involves analyzing soil and rock properties to ensure safe construction practices. This includes assessing the suitability of the ground for various types of structures, understanding how different soil types behave under load, and predicting potential issues such as settling, sliding, or liquefaction. By evaluating these geological factors, geotechnical engineers provide essential data that informs the design process and safety measures needed for foundation support, slope stability, and overall site development.

The role of a geotechnical engineer is crucial because inadequate understanding of soil and rock properties can lead to structural failures or expensive remediation. In contrast, other options, such as designing hydraulic systems or manufacturing pneumatic devices, fall outside the typical responsibilities of a geotechnical engineer, which focus specifically on geological materials and their interaction with structures. Additionally, while overseeing construction management may involve some aspects related to earthworks and soil, it is not the primary focus of a geotechnical engineer's expertise.
