How to say "not until..."

[Gustaf Drevin]

Bonjour tout le monde!

Hi guys, I would like to know if you know how to say something to the effect of "not until (this), (that happened)". I have found ne ... avant que, but that is a bit too verbose.

Merci d'avance!

I am not so sure myself but I think you can sometimes say "Il  a fallu (qqchose) pour que..." 

That seems  more like a causal connection than simply temporal but at least its another option.

You can also often use "ne .... que" to express this idea.

For example:

Nous ne pourrons commencer le projet qu'après la signature du contrat.

"We will not be able to start the project until the contract is signed."
