Wiss, Janney, Elstner Associates Receives 2021 Grande Pinnacle Award

Oberlin, OH, February 8, 2022—The winners of the 2021 Pinnacle Awards were announced during the Natural Stone Institute Awards Ceremony at StonExpo/Marmomac at TISE in Las Vegas. Fifteen projects were honored with Pinnacle Awards of Excellence. The 2021 Grande Pinnacle Award was presented to Wiss, Janney, Elstner Associates in Northbrook, Illinois for their work on the Wyoming State Capitol Restoration project.

The Wyoming State Capitol is a National Historic Landmark designed in the Renaissance Revival style. The building was constructed in three building campaigns completed in 1888, 1890, and 1917.

Prior to restoration, the sandstone was severely damaged due to water exposure, weathering, and inappropriate previous repairs. A challenge of the project was to balance the necessary stone repairs to address life-safety and long-term performance, while preserving the original stone and providing an acceptable aesthetic appearance within the established budget.

To accomplish this, the restoration effort included accessing the original stone quarries and selection of new slabs to match the existing stone. Stone dutchmen repairs were then shop fabricated with standardized profiles and hand-carved and blended by stone masons in the field. Stone repairs also included retooling in the field to replicate the historic appearance and improve slope on horizontal surfaces. Approximately 1,135 stone units were fabricated for the project.


The Natural Stone Institute would like to thank the sponsors of the 2021 Pinnacle Awards: Marmomac (Grande Pinnacle Award), MAPEI (Commercial Awards), GranQuartz (Residential Awards), and Coldspring (Renovation/Restoration Awards).
