All the windows broke at the first floor. Powder-actuated fasteners that attached the wood sills of the wall to the slab failed by pulling loose through the wood.

Temporary shear walls are needed prior to reentry. Stan will be making further investigations to find out if the gypsum panel edges were pulverized by nail pullout."
