User blog:Engineer Joe/Contract Buildings - Help Needed

I am looking for help finding buildings from contracts that CANNOT be bought from their shops. For example, these cannot be bought from Mrs. Williams shop but are earned during the course of completing her contracts:

I am building optimization models to find the best combination of buildings for each completed contract station. The only piece of the puzzle I am missing is buidings like above that are available for that station. I have not found it on this wiki or anywhere else. Any help contributing to this would be greatly appreciated and help speed me along to posting the best possible combination of buildings for each contract station.
