A Geotechnical Engineer is a specialized civil engineer who focuses on the behavior of earth materials. They study soil, rock, and groundwater to assess how these materials will interact with structures like buildings, bridges, and roads. Their work is crucial for ensuring the safety and stability of construction projects. These engineers conduct tests and analyses to determine the strength and stability of the ground. They provide recommendations for foundation design, excavation, and earth retention systems. By understanding the properties of the earth, Geotechnical Engineers help prevent structural failures and ensure that projects are built on solid ground.
