One end of this triple girder (2 story home) rested on the inner portion of a hollow CMU wall. I didn’t have my tape, but I think it was less than 3 inches. Even if it was 3 inches, is it OK to rest on a block like this? Seems to me it would be quite likely for it to break the block.
Also, the other end was completely unsecured. Had a slight twist. How would you secure a girder hanging out in the center of the crawl space like this?
