During the time it took to identify and fix the problem, sheets of plywood replaced many of the missing panes, earning the nickname "Plywood Palace.". A structure should have redundancies to reduce the possibility of progressive failure. The purpose of this system was to eliminate any further movement in the building and to stabilize it during the subsequent construction operations.
