She'll distract herself reading electrical engineering during the flight so she doesn't accidentally pay attention to the nearby geography.
For such a secretive and well-paid project she follows the blueprints exactingly, leaving no trace that she in particular was involved except by the methods used. She makes several suggestions - things she honestly thinks would better secure the place against earthquakes etc, though she doesn't know enough about the area to be sure about what's needed.
It takes a decent amount of effort, but she can tie the metal to the rock wall on the molecular level by turning the mountain wall into a steadily decreasing not-quite-an-alloy that fades to stone as it gets further away. The two things are as close as she can get them to being a single object by the time she's done.
When they're back and the payment from someone-probably-affiliated-with-the-Pro
She'll make a house/apartment building and fancy office area for Laura and any more people she might decide to hire with the budget - which would stretch to hiring someone, if barely - somewhere on the mountain if she wants.
Here's a thought... If she makes beaches and hotels, would tourists come? Probably not - she's not famous and even if a parahuman built it, from the outside her mountain looks like little more than a pretty pile of rock in the middle of the ocean.
The point would be to have a stream of income that doesn't involve her constantly doing jobs. Are there better ways to achieve that?
Alright. Laura can handle most of the setup for that right? That's what she's getting paid a high-but-not-obscene amount for after all.
Can she get New York to help recommend her publicity-boosting disaster cleanup services to other cities? Or possibly to hire her for future infrastructure projects like subway or sewer expansions? Municipal work, infrastructure stuff remains mostly her favorite kind of work.
Maybe take a tour of Africa and dig wells and make roads. Even if she'll probably be attacked it might leave the average person better off. Or maybe it'd just invite retaliation. She's not sure about that one.
As for a lot of Africa, it might come to her attention that people aren't in enough agreement about what the best thing to do with it for them to have actually done anything. She may interpret that information however she likes.
Time passes. Behemoth's going to show up soon. One day Mountain tries to find Glam, to remind them about making her something sharp enough to hurt it.
"Like what? Giant stalactite? You know my stuff disappears half an hour after I stop paying attention to it, right?"
"I was assuming you can pay attention through cameras. If you're not going to be there yourself, that is. You said you hurt Leviathan after all. Wouldn't blame you for staying far away from the monsters, though."
"You're powerful enough that you'll surely be welcome. Especially with the whole truce thing. But nobody ought to feel like they must fight. No humans, at least. I... May have noticed something along these lines when we had that fight in the last of the rubble. The resemblance wasn't intentional."
"Reasonable. I am not really good at social things, so tell me if I should drop something, okay? That said, if you decide not to or just don't work up the nerve, you can always arm me for the first few minutes 'till it expires, and fly away. Help me strike some small blow. Better than nothing."
"Mm. Yeah. But physical things and solid objects tend to not be very effective against them."
"What about a light saber, from those charming Star Wars movies? Remarkably similar to Burning Blade, I'm still annoyed I can't replicate it here. Or I could levitate your anti-Leviathan gun somewhere with good visibility, far away from whatever it does. Does your paying attention extend through cameras? Binoculars?"
