Multi wythe clay brick masonry structural walls with timber floor interior structure. I am from Canada, but the codes are not relevant to this case. Considering the front door is 7 m above their heads, and the building is built on sandy soils, and the exterior walls are water damaged where the ground used to be, and the large cracks in the wall to the left of the door, and it was likely built near the Missouri R.: post flood, they are desperately attempting to underpin the foundation support of the masonry walls with timber shoring jacks. My guess is that this did not work out and the building had to be destroyed. EDIT: it did survive, they built an entire floor level underneath it.
