The most useful answer was already given by Mikel. The individual page for any given station type lists all those who can construct it. Those parties should hopefully be aware that they cannot "assign" datacards in the manner of production, and would be able to inform anyone contacting them of the requirements to build stations. All other information is superfluous, and contributes only to encouraging the OP to ask again, the next time they have a question that they can answer themselves by visiting the Rules pages. That wastes both their time, and ours.
