Need Answer To The 2 Simple Questions

1) So I just came back to the game since the first release, and so much has changed. In regards to synthetic population growth, I know you increase pop with the manufacture pop order but is that the only option? No actual buildings? click here www.omegle.top

2) Finally, does placing a +1 "all construction building" on a +1 ship construction tile do anything at all, even just for ship construction?

Appreciate any help![spoiler]
