Civil Engineers design, build, and help maintain public works (structures like bridges, dams, and buildings created for communities by the government). They create and improve systems to make sure modern societies have drinking water, reliable transportation, a clean environment, and energy. Civil and Water Resource Engineer Cynthia Clark helps design and maintain systems to distribute water among the people of Idaho. Civil Engineer Tysheina Robertson is helping build Denver’s first commuter rail. When Ornithologist Laura Gooch worked as a Civil Engineer, she helped provide Texans with the water they needed and helped clean up toxic waste in Ohio. And Civil Engineer Rachel Davidson studies ways to improve systems that help protect people from natural disasters like hurricanes and earthquakes.
