They had closed one lane of a busy local street, but the traffic control guys were not pros, (we have a good outfit in town that I have worked with before) but turned out to be just grunts of the construction outfit I was doing the pick for. Poorly marked, way too close to my outriggers, I hauled more marker barrels over myself to partially solve that. It was 9 at night, and snowing heavily. I was there to lift the 15 K trench box out of the hole, and put it on a lowboy. Earlier that day, the contractor assured me it'd be broken down to 6 pcs., with the heaviest being 6 K or so, so I showed up rigged with my usual one part line. It was still all in one piece, and I waited while an excavator tried to separate it, just putting a bigger bind on it, so then it came to me to lift it, to unbind it. I pulled up to my 7500 single part line limit, and then a bit more, and that didn't do anything, it was bound up. That's when I told them I'd have to rig for a two part line, and if they would have had the thing separated as planned it wouldn't be necessary and that's why I showed up rigged for a single part line. So, I drop the boom in the only area I had available, forcing me to climb into and out of the slippery trench, after getting my load block out, all while being blinded by the works lights and the heavy snow and wind continued. Just as I'm reeving the block, the contractor comes over and tells me we are getting shut down, the head honchos on the project wanted to see my CCO card, a lift plan, and a diagram showing how my tail swing wouldn't get in the way of traffic (all they had to do was look, it doesn't). I said, "OK, climbed back across the trench, put the load block away, caged the boom, sucked in the outriggers, got my CCO card out of my wallet and walked over to the two guys and showed it to them, and said "you guys have a nice night now, and good luck with your project," and drove off. While I was doing this the contractor asked about the next night, I just told him I was busy, he called twice today and I didn't pick up. I don't mind filling out a lift plan, but to get it sprung on me, in a snowstorm, at night, with cars whizzing by too close, nah. Plus the low boy had a bunch of crap already on it, which would had forced me to reach over it and maybe out of my chart, everything was screwed up, I have no regrets in driving off, in fact it felt good! I took my ball and went home.
