Civil engineering is a professional engineering discipline that deals with the design, construction of systems necessary for our modern society to function, and maintenance of the physical and naturally built environment, including works like roads, bridges, canals, dams, and buildings. It is traditionally broken into several sub-disciplines including environmental engineering, geotechnical engineering, structural engineering, transportation engineering, municipal or urban engineering, water resources engineering, materials engineering, coastal engineering, surveying, and construction engineering.
It encompasses many technical specialties whose focus is the design of large, normally one-of-a-kind, and facilities such as bridges, buildings, tunnels, highways, dams, waterways, airports, flood control systems, coastal protection systems, water supply networks, and waste treatment plants. Civil engineering takes place on all levels: in the public sector from municipal through to national governments, and in the private sector from individual homeowners through to international companies. As our society expands, challenging opportunities will continue to be available for Civil Engineers practicing in their own private firms, in large companies, or in governmental agencies.
