SOLUTION

The initial phase was a code mandated City of Chicago facade examination. The second phase was a due diligence investigation to gain a general sense of the condition of the facades and the causes of distress, as well as to gain a general sense of the order of magnitude of costs for the recommended repairs. The third phase included testing and trial to gain more knowledge of the physical characteristics of representative facade materials, as well as cleaning trials, reviewing existing conditions of the monumental windows for restoration and the existing roofing to provide information for the design of appropriate repair scope. The following scope of work was completed as part of the exterior facade rehabilitation:

• Removal and replacement of 10,000 square feet of brick;
• Removal and replacement of 4,500 terra cotta units;
• Removal and reinstallation of additional 10,000 terra cotta units;
• Reconstruction of full third-floor terra cotta gutter;
• Repointing of brick and terra cotta at north, east, and west facades;
• Replacement of roofing at all roof and balcony areas installed;
• Replacement of wood double hung windows with new aluminum windows that match historic windows;
• Restoration of monumental wood windows;
• Recreation of eighth floor operating room skylights, and
• Cleaning of existing brick, terra cotta, and stone masonry
