Good Question, SunDevil
This is true, you do have several Culture Centers types and each will have its own special abilities in AIC; depending on your Racial Traits chosen when you started your Character.
In most games when started; you may have up to 3 quick viable scraps.
1: Distribution Center. This is inherent with the CC and should be Scraped at your earliest Convenience.
2: Space Dock. This is also inherent with the CC and should be Scraped at your earliest Convenience.
~Tip~ Possibly a research expedition, an advanced Settlements that can be upgraded to Towns and Cities, Computers, Planetary Shields, a needed Resource Colony, Planet Value Plants, etc. may be built as new Construction for above.
3: Space Yard Facility. This will require more thought as it applies to your current games events and Progress. For example: what is your current Ship Yard rate on your BSYs orbiting the Home World. Do you have a few Construction Colonies already built up and the Home Worlds Space Yard is now possably redundant and a newly acquired Devise or Facility may be far more profitable and/or beneficial
A lot of players like to make tough Decisions and do like this aspect
It is possible to Set up AIC to have less Cultural Centers, what would you suggest be added in its Place. In the start of the game there is no facility near as Productive as your Home Lands Population Center, just as it is with Europe, the Americas, Asia~ well, all the continents in our World.
Now as time goes on in your AIC game, you may find other viable reasons to rebuild a Structure, in the Place of what may become an old and antiquated Population Center.
~Hint~ When you scrap a Home Worlds Culture Center you will have the benefit of its very conducive Recycle Value. When in a jam this could be a Last Mobilization effort.
However this is also arranged in AI Campaign as an evolutionary choice. You must reach an Infrastructure Capability to except this premium fully. It is also best to have a cost-per-effect alternative build.
