Civil engineering is a professional engineering discipline that deals with the design, construction, and maintenance of the physical and naturally built environment, including works like roads, bridges, canals, dams, and buildings. Civil engineering is traditionally broken into a number of sub-disciplines. Civil engineering takes place in the public sector from municipal through to national governments, and in the private sector from individual homeowners through to international companies. Civil engineering is the application of physical and scientific principles for solving the problems of society, and its history is intricately linked to advances in understanding of physics and mathematics throughout history. If you study civil engineering at undergraduate level, you’ll learn to apply mathematics and scientific knowledge (particularly physics) to real-life situations and problems that arise from creating and maintaining structures, taking into account environmental, financial, legal and ethical considerations.
