This barn was on borrowed time. I kept it in use as long as I could by propping it up with the diagonal posts visible on the front. A contractor was going to knock it down with a trackhoe and bury it, but I wanted to spare the landscape and minimize the need to tear up the lawns, etc. So we decided to take it apart and recycle what we could and burn the rest. We had to separate the roofing material and dispose of that correctly. In order to do this safely it was decided we should partially collapse the structure in order to work on it without getting too high off the ground.
The plan worked like a charm as is evident in the video clip. Once the roof was at ground level it was easy to take apart.
