Working off the 6-foot-by-8-foot deck of the addition, the crew first kerfed the mortar joints to receive the steel angle.
The shorter channel was added. The right-angle joint at the intersection of the steel channels was later welded.
The existing second-floor joists, which had been cut back to allow the steel to be inserted, were sistered with new full-span LVL joists.
The crew left a section of sheathing off the addition so they could more easily remove the brick from inside.
