geez we frame the day after the pour and I'm shooting hilti pins into a a deck the 3rd day. Its a 1200 Lb safe folks, he's not driving a 100K Lb truck over it.
Your thinking too much about this.

I guess that was kinda my point. When we pour a bridge, we can drive equipment on it after 7 days, without doing breaks.
You can put you safe on it after 24 hours. If you want to be really safe, wait a few days before you drill the holes in for the bolts.
