Civil engineering is a branch of engineering that deals with the design, construction and maintenance of physical structures such as roads, bridges, buildings, airports, dams, canals, etc. It involves applying principles of mathematics, physics, geology, hydrology, environmental science, mechanics, and other disciplines to develop safe, economical, and sustainable infrastructure that meets the needs of society. Civil engineers work in a wide range of industries including construction, transportation, water supply, waste management, energy production, and telecommunications. They use advanced technology and sophisticated tools to analyze data, design projects, and manage construction sites. The goal of civil engineering is to improve the quality of life for people by providing them with safe and efficient infrastructure that supports their daily activities.
