Civil engineering is a branch of engineering that deals with the design, construction, and maintenance of the built environment, including infrastructure such as roads, bridges, buildings, and water and sewage systems.  Civil engineers use principles of mathematics, physics, and geology to design and construct structures that are safe, functional, and sustainable.

Civil engineers work in a variety of industries, including construction, transportation, water and sewage management, and environmental consulting.  They may work in design and planning, construction management, research and development, or project management, depending on their area of specialization.
