Probably the oldest engineering discipline. Focuses on the built environment everything man-made. Examples are bridges, buildings, railroads, and other construction jobs. The old civil engineering discipline of sanitary engineering has evolved into modern environmental engineering of such significance that most academic departments have changed their names to civil and environmental engineering. These few examples illustrate that civil engineers do a lot more than design buildings and bridges. They can be found in the aerospace industry, designing jetliners and space stations; in the automotive industry, perfecting the load-carrying capacity of a chassis and improving the crashworthiness of bumpers and doors; and they can be found in the ship building industry, the power industry, and many other industries wherever constructed facilities are involved. And they plan and oversee the construction of these facilities as construction managers. Civil engineering is an exciting profession because at the end of the day you can see the results of your work, whether this is a completed bridge, a high-rise building, a subway station, or a hydroelectric dam.
