Infrastructure

From the Encyclopedia Galactica:

Infrastructure refers to the fundamental facilities and systems serving a planet, continent, city, or area, including the services and facilities necessary for its economy to function. It typically characterizes technical structures such as roads, bridges, tunnels, water supply, sewers, electrical grids, telecommunications, and so forth, and can be defined as "the physical components of interrelated systems providing commodities and services essential to enable, sustain, or enhance societal living conditions."

There is no Union 'standard' for local or planetary infrastructure as long as basic needs are met. These needs are unhindered movement of people and goods, ability to attain sustenance needs such as air and water, etc. The lack of standards is due to the wide varience in conditions between settled locations.
