• Define civil engineering?
  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 the oldest engineering discipline after military engineering, and it was defined to distinguish non-military engineering from military engineering.
