About the tech tree for advanced plots

[marieruth]

Will I be informed if an upgradeable building is missing tech outside of nothing appearing in the inventory menu when picking what route to go to for the given plot?

I went through the in-depth series for industrial revolution, and I don't understand how I'll be able to identify everything that I'll need in order to upgrade a building without some pop-up message or notification?

the tech tree HUD isn't exactly detailed either

The design philosophy behind it is focused around experimentation and discovery. The Tech Tree is meant to reveal the requirements after you discover them so you'll have learned how to repeat it later.

If you're not into the experimentation angle, there's a sticky post in the General section on the forum with several spreadsheets the community has come up with that lays out how all of the unlocks work.
