Civil engineering is arguably the
oldest engineering discipline. It deals with the built environment and can be
dated to the first time someone placed a roof over his or her head or laid a
tree trunk across a river to make it easier to get across.
The built environment encompasses
much of what defines modern civilization. Buildings and bridges are often the
first constructions that come to mind, as they are the most conspicuous
creations of structural engineering, one of civil engineering's major sub-disciplines.
Roads, railroads, subway systems, and airports are designed by transportation
engineers, another category of civil engineering. And then there are the less
visible creations of civil engineers. Every time you open a water faucet, you
expect water to come out, without thinking that civil engineers made it
possible. New York City has one of the world’s most impressive water supply
systems, receiving billions of gallons of high-quality water from the Catskills
over one hundred miles away. Similarly, not many people seem to worry about
what happens to the water after it has served its purposes. 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.
