That is a shit ramp.Protecting the edge of the finished slab. And to make the transition from the sloped finished slab, to the flat slab on the other side easier.
They just did it again too, plumbers this time. The other lifts will go over it no problem. I had to lift it with a Burke bar, jam 2x4 under the tires, and tell them not to try again.
Jobsite I was on, the sup was all hot and bothered to get the TCO. Had the carpet guys come in over the weekend and lay down the carpet tiles. Come Monday morning just about every trade sat down and did nothing. There was still electrical, plumbing, computer dorks and use using lifts. They wanted all the trades to provide their own floor protection. All the foreman got together and said fuck you, we ain't buying shit, if you want it protected you need to do it. We'll be back when you are ready. Magically, a HD truck showed up 2hrs later stacked full of plywood. The dumb fucker set the job back by at least a week from that stunt alone.
