Assignment: Limestone Facade
Restoration
Duration: In Progress
Project Value: $700,000

Corrosion of steel shelf angles and lintels within the walls of this Michigan Avenue treasure was stressing the limestone facades. Design Installation Systems was asked to complete a façade restoration project which included steel repair and replacement. Stone work included pinning limestone panels, repairing spalled stones and full stone replacements where panels could not be salvaged. The work also included parapet wall repairs and rebuilding. To help keep the walls leak free tuck pointing, sealant repairs, and crack repairs were completed at selected areas on each elevation.
