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);  which they also do for  electrical power and lighting networks and telecommunications, computing and monitoring networks.
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.
