For the building that got caved, just following the pattern and uncracking the mortar/blocks+ support joists should do it just fine. It’s not like it super matters for fire rating or the such, brick doesn’t really care for that, and the wall that got caved was exterior and not adjoining another structure, so it probably only needs 1 hour rating and an exterior brick wall for a building that tall is probably somewhere in the range of a foot thick or fire rated for 10 hours.
Not those big bucks only small construction man bucks.
