[R&F] How to use builder's charges to fasten district project?

[Saint James]

I built Royal Society in Government Plaza district.

Description says:
Builders gain the ability to use all of their charges to provide bonus Production to a District Project. Once per city per turn.

But I can't see any UI buttons for this action. Can anyone help me with it?

The button for fasten project is near the buttons for moves, wait, sleep, etc :)

pretty good for rushing the spaceship parts. consumes all builder charges and the more charges there are, the more production it adds. i used that to speed up the space victory in the end. the last missing part showed 13 turns to completion or something, but by chain boosting it with builders, it was actually done in about 5 turns or so.

Not at all.

Just for me to understand - the German localization isn't that precise in that case. With the Royal Society workers can boost city projects like theatre festivals etc. by placing the worker on the needed district, right?
You can't rush district-building or buildings like the university, right?

Yeah i'm picking the society for this as well but i never get that button not sure if it's bugged or do we need some other requirement I haven't met?

I fell for the trap of thinking the builder charges could be used in the same way that the Aztec Unique Ability allowed them to rush districts. However, it is only used for the "Projects" that you can build after you've completed a district (for example, a Holy Site Prayers "project" in the Holy Site.)
This is only really useful if you just want to squeeze every last bit of production in to rush a space race project for the victory conditions since the production bonus very inefficient (conversion of production used to create the builder versus production added to the project.)
Of course, everyone has their own definition of "useful" so to each their own.
I hope this makes sense.
And if you already knew this, then yes it's bugged and of course I don't know what's going on.
