Civil Engineering
Civil engineering is the professional discipline focused on designing, constructing, and maintaining the built environment, including infrastructure, buildings, and public works that form the foundation of modern civilization.
Overview
Civil engineering stands as one of the oldest engineering disciplines, emerging from humanity's fundamental need to shape the environment for collective benefit. It encompasses the planning, design, construction, and maintenance of physical structures and systems that enable modern society to function.
Core Branches
