Civil engineering is a branch of engineering that deals with the design, construction, and maintenance of infrastructure and environmental systems. It encompasses a broad spectrum of disciplines, including structural engineering, transportation engineering, geotechnical engineering, and water resources engineering. Civil engineers work on projects such as roads, bridges, buildings, dams, airports, and water supply systems, aiming to create safe, sustainable, and resilient infrastructure that meets societal needs. They apply principles of mathematics, physics, and materials science to analyze and design structures and systems that can withstand natural forces and human impact. Civil engineering plays a vital role in shaping the built environment and improving the quality of life for communities worldwide.
