The limestone cladding at the first three floors of the Wall Street elevation is complete. Swing stages or hanging scaffolding is positioned at the fourth floor level to allow masons to install the stone cladding. In the early 1930s construction of cladding was evolving from a process that required masons to work from the exterior to one where all cladding materials were installed from the interior. The heavy steel construction of the sidewalk bridge was required to support the heavy loads of the building materials stored there temporarily. A stiff legged derrick was located on the exterior of the structure directly over the opening in the bridge.
