Case Study: Heritage at Millennium Park

The Challenge: Demolish 5 buildings on North Wabash Avenue in Chicago, save their historic facades, and integrate those facades into a new 57 floor tower.

The Solution: Survey the existing structural and masonry backup conditions exposed by the demolition of the original facade.  Prepare shop drawings integrating the existing structural conditions with the architect’s design intent.  Prepare GFRC panel layout, shop tickets and frame design drawings for fabrication.

The Result: A GFRC panel facade which replicates the appearance of the original facade

Case Study: 141 Wooster Street, New York

A metal cornice in New York City required replacement. The damaged cornice was removed and the existing conditions were surveyed.  Shop drawings and GFRC panel drawings were prepared for the replication of the cornice.  The designers opted to replace the sheet metal with GFRC to simulate a limestone cornice.
