In road and rail transport, and water and waste management networks, civil engineers design the infrastructure (but urban planners could develop the general layout of roads, sidewalks and public places); electrical power and lighting networks are designed by power and electrical engineers; and telecommunications, computing and monitoring networks are designed by systems eingineers.
Generally road and rail transport networks, as well as water and waste management infrastructure are designed by civil engineers, electrical power and lighting networks are designed by power engineers and electrical engineers, and telecommunications, computing and monitoring networks are designed by systems engineers. In the case of urban infrastructure, the general layout of roads, sidewalks and public places may sometimes be developed at a conceptual level by urban planners or architects, although the detailed design will still be performed by civil engineers.
