Steve,
Could you give a run down on the size in tons for each installation, how big jump gate components are and the size of one unit of ore (are all ore types the same tonnage at 1 unit?) and anything that can be transported by a freighter or similar? Would be handy for designing transports, asteroid miners, jump gate construction ships and sorium miners.
You no longer need jump gate components in v4.1. Construction Ships can build jump gates by themselves.
For the rest:
Regular factories, Mines etc. require 5 cargo holds
PDC components require 1 cargo hold
Trade goods require half a cargo hold, as does infrastructure
A research lab requires 100 cargo holds but you can transport sections of it
Terraforming installations require 25 cargo holds and you can transport those in sections too
2500 tons of minerals will fit in one cargo hold
