It was necessary to have a 6 in space between the portion of the house being lifted and the portion that will be left behind. So 10 minutes for each beam of actual cut time. And at least another five minutes of monkeying with blades and moving the ladder Etc.
We ended up using jack posts, so that it didn't have to be done while the crew waited.
The Diablo carbide metal cutting blades might be slightly faster than the thinner Milwaukee blades. After making two cuts, the carbide blade was still in good shape. But then it broke, so ultimately didn't cut any further than the Milwaukee metal cutting blade. It was a difficult spot, where there was some bending at the point where the blade inserts into the Sawzall. In a shop situation, I'm sure the carbide blade would last much longer, since the teeth on the Broken Blade are still in perfect condition.
