This building’s exterior façade was clad from the 3rd floor up with Indiana Limestone and terracotta glazed in the colors of the rainbow creating vertical ribbons of eleven different colors around the façade and with Absolute Black Granite base at the ground level. The Indiana limestone façade clad the slab edge spandrels, column covers, and windowsills. This façade is supported by CFM stud walls, which proved extremely challenging due to variable tolerances. Support clips were custom-made on-site to meet field conditions.
The terracotta panels fit between the standard window width and the variable column spacing. This resulted in 21 variations of plan profiles and mitered knife edges on the terracotta panels, which were very fragile. Our studio designed custom frame supports for every opening due to variable tolerances in the field.
The project had various challenges, but our team found ways to work with them. The project required swing stages within and over the existing building, and the access for loading the swing stages with 2-inch limestone veneer and terracotta panels was through a single window. The project was a great success, completed on-site and without an accident, and the owner was very pleased with our team’s work.
