new opening in existing cmu wall
(OP)
I am investigating the possibilities of designing / detailing a new opening in an existing 12" CMU wall. The wall is load bearing and the dimensions of the new opening would be approx. 8ft. square. My question is does anybody know of good procedures and/or details for accomplishing this work? A colleague suggested providing a steel frames made of channels bolted together through the wall and then cutting the opening. Thoughts?

We then bolt through the wall, enough to carry the weight of the wall into the channel. These can be either through-bolts (hard to do) or adhesive anchors.
After the channels are in place, the contractor begins cutting the CMU away in small sections just below the header channels; installing a cross cover plate under the headers to tie the two header channels together and carry any loose masonry.
Once they've worked across the opening, then the remaining masonry below can be removed as well.
