Enjoying a smooth drive, happy with a well planned market place, take a moment to thank a civil engineer for the roads you travel, the market place you are in. But, these aren't the only contribution civil engineers have made to life in the 21st century: They are also credited with synchronizing traffic lights, designing Homes, building bridges, erecting industrial facilities and constructing recycling plants. Most people think of civil engineering as people who build highways and waste treatment plants, but its much more. Civil engineers are responsible for planning and designing a project and having it constructed to the required scale.
