Civil engineering is one of the oldest and broadest fields of engineering. It includes designing, building, and managing infrastructure projects like roads, bridges, dams, and sanitation systems. Civil engineers work to improve quality of life through transportation networks, water systems, and addressing environmental issues. Some major areas of specialization include structural engineering, transportation engineering, geotechnical engineering, and water resources engineering. The document highlights seven iconic examples of civil engineering wonders: the World Trade Center, Eiffel Tower, Empire State Building, Statue of Liberty, Metropolitan Museum of Art, Golden Gate Bridge, and Burj Al Arab hotel.
