The Spalding Building, designed by American Renaissance architect Cass Gilbert and built in 1911, is on the National Register of Historic Places.

The challenge was to maintain the building’s historical significance while using modern construction techniques and materials. For instance, this project used BIM computer modeling along with CAD to significantly decrease the design time and allow collaboration between the architect, engineers, building product manufacturers and contractors.

Some of the project conundrums included installing stainless steel panels while achieving the necessary sound-transmission rating, and bringing the fire rating of the building assemblies up to code. Additionally, seismic upgrades were needed due to the age of the building.

Judge’s comment: “The requirement to maintain the buildings historical significance along with the complexity of the space demanded a collaborative effort by everyone involved. The pre-construction product research, investigation, and mock-ups provided by the acoustical contractor helped to create a beautiful end result.”
