Followed by 3 screenshots showing my Industrial Center Building and the Iridia Exchange Wonder/Achievement (can only build one in the entire Galaxy) (which is a special building of ONLY the Corporate Sector), plus showing the Elon's Lift (which is under construction).
The Industrial Center is at Level 5 , 1 level from the Manufacturing District to the North West of it, and 4 Levels from the Iridia Exchange. It will also be getting another 3 levels in 2 turns when the Elon's Lift (another Wonder) to the North East of it gets Built).
Elon's Lift is currently being constructed and will finish in 2 turns. It will get 3 Levels from the Industrial Center and 1 Level from the Manufacturing Center, These levels raise the production bonuses that Elon's Lift will generate.
If you look at reply 10, you can see 23.48 Minerals being inputted and the Industrial Center is adding 15% and the Manufacturing District is adding 6.2%, and the Approval is 99% along with other bonuses to get a final 35.15 manufacturing output.
When Elon's Lift finishes in 2 turns the manufacturing output will increase. It will get a +20% for itself and another +10% for it's levels as well as giving 3 levels to the Manufacturing District and to the Industrial Center.
Many buildings, but not buildings on special Resources, your Capital Building, and some Wonders/Achievements, will get level bonuses from the tile they are on, from adjacent tiles, and from buildings in adjacent tiles. These increased levels increase what each building does, which will be shown by the tooltip over that building.
For Instance the Capital Building gives a +2 level Bonus to all buildings next to it that get level bonuses. The Capital Building itself does not get level bonuses (too bad).
You will have to examine each District or building to see what bonuses they give and receive to/from adjacent Buildings.
As you play the game you learn what buildings you want to build where.
Learning how and where to place Buildings is an Art that takes a lot of experience, and will depend on your needs, currently available Techs, future Techs, and new tiles that get added to the surface. So try to plan for the future as well as the present.
Many Districts and Buildings can be torn down and replaced with others. However, some Buildings can not be torn down after they are built, particularly some of the Wonders and Achievements.
At present The Civ Capital building can not be moved. However, when you turn a Colony into a Core World by appointing a Leader as it's new Governor, you can place the Core Capital Building on it's location. After that it can not be moved either.
