Assignment: Terra Cotta & Masonry Rehabilitation
Duration: 2 Years
Project Value: $700,000
The main focus of this project included replacement of damaged terra cotta with GFRC replicas. Pieces replaced included corners, ashlars, window heads, and decorative profile units. Extensive steel restoration was completed before replicas were reinstalled. Existing fractured pieces of terra cotta deemed salvageable were restored by means of pinning, epoxying and patching with Jahn Restoration Mortar. Many pieces were able to be removed and reinstalled with no restoration required. As a cost and time saving alternative, limestone replacements were used at several of the corners. The limestone matched the existing terra cotta closely without the use of supplemental coatings. Miscellaneous masonry restoration was then completed, including brick replacement, tuckpoinintg and caulking.
