Civil Engineering is a branch of engineering that embraces expert practices which work towards creating, maintaining and operating the social, commercial, and industrial infrastructure that sustains a modern society. Such infrastructure includes all building construction , roads, railways, canals, airports, harbors docks, water supply, drainage, flood and erosion control, bridges, tunnels, pipelines, dams, irrigation systems, electricity generation, and industrial facilities.
This branch of engineering uses mathematics, physics, mechanics and the properties of materials in order to provide cost – effective solutions to building problems. This is brought about by combining the standard and best available expertise, labor and materials, keeping in mind the time, cost, hazards and social responsibility.
Historically, military engineers were responsible for the design and construction of roads, fortifications, bridges, and the destruction of enemy facilities by tunneling and explosives. Eventually, this expertise entered the civilian domain, thereby becoming the profession of the civil engineer, which has nowadays become a competitive and quite sought after profession.
