The week we had to lift a 12-ton AC unit onto a roof with a 5-foot gap

Got called out to a job in Phoenix where the building plans were off by a good margin. We had a Liebherr LTM 1050 set up, but the spot for the unit was a full 5 feet further in than the drawings showed. Had to re-rig everything on the fly, using a spreader bar and some extra long slings we luckily had on the truck. My signaler and I went over every hand sign twice because one wrong move meant hitting the parapet wall. Anyone had a similar fix with bad plans?

Measure everything yourself every time? I mean, that sounds good in theory, but what about when the site isn't ready for you to get up there before the crane rental clock starts ticking. Seems like the real world doesn't always let you do the perfect check.

Honestly this happens way more than people talk about. Tbh it's not just crane work, it's like a rule for life now. You can't trust the plan someone else gave you, you have to go see the real thing yourself. Ngl it's why I double check my own grocery receipts or the address before I drive somewhere. That extra five minutes of checking saves a huge headache later, every single time.

Sounds like a real headache, but honestly, I'd never trust the drawings that much in the first place. We always do our own measurements on-site before the crane even shows up. Saved us from that exact mess last summer on a warehouse job.
