Geotechnical Engineering...
Geotechnical engineering, also known as geotechnics, is a branch of civil engineering concerned with the engineering behavior of earth materials.
It uses the principles of soil mechanics and rock mechanics to solve its engineering problems. It also relies on knowledge of geology, hydrology, geophysics, and other related sciences.
Geotechnical engineers are responsible for assessing the subsurface conditions at a site and designing foundations and other structures that can safely support the loads imposed on them. They also play a key role in the design of earthworks, such as embankments, dams, and tunnels.
Geotechnical engineering is a critical field that plays a vital role in the design and construction of many types of infrastructure, including buildings, bridges, tunnels, dams, and highways. By understanding the behavior of soil and rock, geotechnical engineers can help to ensure that these structures are safe and reliable.
At GCA, we are those engineers.
