Geotechnical Engineering focuses on the engineering behavior of earth materials such as soil and rock. Geotechnical engineering uses principles of soil mechanics and rock mechanics to investigate subsurface conditions and materials by determining the relevant physical/mechanical and chemical properties of these materials. Since most every civil engineering project is supported by the ground in some manner, geotechnical engineers interact with most of the other subareas of civil engineering. Typical geotechnical engineering projects include the design of foundations for various structures, tunneling, the design of roadway sub-grades, design of earthen dams for water storage or flood control, or the disposal of waste products by burial in the ground. Civil Engineering is the broadest of all engineering professions and encompasses the application of science and technology to the planning, design, analysis, construction, operation and maintenance of the infrastructure and natural environment. Civil engineers are the fabricators of modern society and the protectors of our environment. Civil engineering program emphasizes the complex interrelationships between infrastructure, social systems, and the environment. We develop civil engineers who will seek to sustainably and equitably design, management, and construct infrastructure systems, and who are prepared to innovate with new materials and create and use digital and virtual technologies. Civil infrastructure is diverse, including many subsystems such as stormwater and drinking water systems, waste management systems, neighborhoods, highways, railways, high-rise buildings, and bridges. We develop the insight to anticipate how changes in one subsystem may affect the others and ultimately the environment, energy systems, communities, and the quality of life.
