What makes acceleration clauses such a trap in construction contracts?

If you're a subcontractor, acceleration clauses are so dangerous. You've got to lock in if you're going to get paid. What we see all the time with acceleration clauses, they've asked you to speed up the contract, which is totally fine, you're happy to do it, but you've got to ask, hold on, are you asking me to speed up because you think I'm slow, or you need the project to be sped up? Because if you think I'm slow, well, I'm not, and we're not playing that game. I guess I figured this out now, but But if you're asking me to speed up because of your own reasons, I wanna make sure I'm paying for it. Because what actually rolls out most of the time is they say, no, no, actually we asked you to speed up because we thought you were late. And you're like, well, I gave you all this additional stuff. I was managing my job the way I wanted it and I wasn't late. So you gotta figure out, are they gonna pay you for asking you to speed up before you start speeding up?
