Good on her!
Toss that particular grenade back in their laps & show them you're still holding the pin. If they refuse to cough up the cash to do what they require, the individuals in charge of getting it done have a perfect excuse for not doing it.
"You want me to rip out all this otherwise good stuff, I've told you it'll cost me buckets of cash, and all you'll give me to cover it is barely a third? Sorry, but it'll take us longer to get the job done if we're forced to devote so little funds to doing it."
But then again, given how much money the government has *already* shoveled into their coffers over the years, a threat of "Do it or we want our money back" would be enough of a cannon to their pea shooter to make them think twice about pissing off the money fountain controller.
On one hand I want the corps to get paid to do the job, but on the other hand I know they already have been a thousand times over.
I'll get the popcorn, someone else bring the beer...
