Civil engineering is a professional engineering
who deals with the design, construction, and maintenance of the physical and naturally built environment, including works like roads, bridges, canals, dams, airports, sewerage systems, pipelines and railways.

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 traditionally broken into a number of sub-disciplines. It is the second-oldest engineering discipline after military engineering and it is defined to distinguish non-military engineering from military engineering,
