Civil Engineering is a branch of engineering that focuses on the design, construction, and maintenance of the physical and naturally built environment. This includes infrastructure such as bridges, roads, dams, and buildings. Civil engineers play a crucial role in ensuring that these structures are safe, sustainable, and efficient. The field encompasses various sub-disciplines, including geotechnical engineering, transportation engineering, and environmental engineering. Civil engineers must consider factors like materials, environmental impact, and community needs when planning and executing projects, making their work vital for societal development and safety.
