Yes, it's amazing when they actually succeed in delivering something at the end.
There is almost always some substantial fraction of the budget that went to corruption. (For nuke plants in the US, it is generally 2/3 or more of the total spend, often 3/2 of the original budget.) Nobody actually involved wants the project ever to deliver, because right then the money stops flowing; or, anyway, not until the kids graduate college or something.
So it is always amazing when these projects deliver.
Well at least I they got it finished.
Some projects esp. in Africa get fully financed but never even start.
