Some of the numerous subdivisions are transportation (e.g. railroad facilities and highways); hydraulics (e.g. river control, irrigation, swamp draining, water supply, and sewage disposal); and structures (e.g. buildings, bridges, and tunnels).
Civil Engineers are usually found in one of the following organizations
There are three kinds of civil engineer:
Highways civil engineering is concerned with improving, designing and maintaining roads of all sizes (from motorways to B-roads), in all sorts of location.Civil engineering: Transport
Chartered engineers specializing in the transport sector focus on the design, construction and maintenance of structures, supporting transport networks, such as bridges, tunnels and railway tracks.Civil engineering: Water and Marine
This area of civil engineering encompasses all kinds of coastline developments including jetties, piers, harbor work, docks and flood protection, plus any other structures used for carrying, storing or distributing water and wastewater.
