How to become a civil engineer

Introduction:
A civil engineer is a person who practices civil engineering; the application of planning, constructing, maintaining, designing and operating infrastructures while protecting the public and environmental health, as well as improving existing infrastructures that have been neglected. With an increasing population and old roads, bridges and buildings in need of repair and maintenance, the demand for preservation, replacement and creation of new structures will continue to rise. Civil engineers play a key role in designing, constructing and repairing the infrastructure that supports our lives and our lifestyles and will continue to be a crucial component in meeting this demand. Civil engineers are responsible for the design and maintenance of bridges, buildings, airports, tunnels, dams water supplies and sewage systems. Natural disasters such as hurricanes and earthquakes plus a large number government regulations make civil engineering a challenging, lucrative and diverse career. Some of the specialties in civil engineering include transportation, bridge or structure design, environmental engineering and public utilities.

Mathematics and science are very important in civil engineering. Without civil engineers we would not be able to work out how much material was needed to build something. We also wouldn’t be able to decide if a piece of land was strong enough to support the world’s tallest building! To be a civil engineer is mathematics + science = civil engineering How much math is used in civil engineering?

It depends on what sub-branch of Civil you are referring to: Transportation folks have equations to describe traffic flow. Structural folks: to describe loading on beams and structures Environmental folks have equations to describe chemical reactions in lakes and streams Geotech folks : to describe soil loading behavior.

Hydrologists : to describe surface water flow.

The thing is most of the final work is constrained by codes or is done by computer and the day to day equation hacking is done to make sure that you're going the right direction before plugging things into the computer or get a ballpark estimate. So, most of the equations are pretty simple.

let's take an example: (transportation)

If you have two bridges across your local body of water (lake ,river, bay) and you have to close one of them for the weekend to do repair work, you would be interested in knowing if the other one will be congested. So, you make up a simple equation based on what you know.

Demand = Normal hourly demand on bridge 1 + normal hourly demand on bridge 2 If Demand exceeds capacity on the open bridge, you have problems!

The next step would be to quantify how much excess demand you have, develop alternate routes, estimate average delays, and expected diversion rates.

Another example:

If you have a uniform distributed wind load of X, and a cross sectional area of Y, then the force (F) on a sign will be X*Y and can be treated as though it was a point load at the sign's centroid. Assuming that the sign is symmetrical and supported from the middle, The bending load /bending moment (or overturning moment) at the base of the sign is H*F and you'd better be sure that whatever post you are putting it on can hold it up when the wind blows.

(and yes, 90% of the time you just look at the table that says "use a 4x4 wood post for signs between this area and this area")

But when you have a structure that was put in place 11 years...
