They were probably told they couldn't go on the pristine grass with the boom-truck and that was the end result.
A few years ago we were using something similar (much smaller of course) for our landscaping company to place these giant landscape boulders, and the owners didn't want us to so much as scuff the turf. In the end we couldn't move a couple of the rocks because the load was too much for the boom length. At least my crew boss was smart enough to call it off and not have something like that happen!
