The week we had to lift a whole HVAC unit over a live power line
It was this past April in Cincinnati, and the site manager came to me with a set of prints that made my stomach drop. They needed a 5-ton rooftop unit placed, but the only path was directly over a 12kV line that couldn't be shut off. My boss just said, 'Figure it out, but don't touch the wire.' We spent three full days planning, using a 120-ton mobile with a super long boom to get the reach and height. The actual lift took 45 minutes of the slowest, smoothest operation I've ever done, with a spotter on the radio the whole time. You could hear a pin drop on site. When we finally set it down, the electrician just shook his head and said, 'I've never seen a dance like that.' It was a bad week that turned good because the planning paid off. Has anyone else had a job where the prep time was longer than the lift itself?

Your boss gave you the classic "don't die" project plan.

Heard about a crew doing a similar lift over train tracks with a live third rail. That prep work is everything, makes the actual move look easy. Your spotter must have had nerves of steel.
