A civil engineering degree is a qualification awarded to individuals who have completed a course of study in civil engineering, which deals with the design and construction of infrastructure such as roads, bridges, buildings, airports, sewage systems, water supply networks, and other structures. Civil engineers use their knowledge of mathematics, physics, and materials science to analyze, design, construct, and maintain these structures for public benefit. A civil engineering degree is typically a bachelor's or master's level qualification that prepares students for careers in the field of civil engineering.
