PGC helped coordinate the search and selection of glass art for RexxHall Realty, LLC to upgrade its downtown Pittsburgh office building at 11 Stanwix Street, an historic 1960s-era high-modernist tower. PGC coordinated the Request for Proposal (RFP) process from start to finish to commission artists to design and construct a permanent glass lighting installation for the lobby. The installation "Rivers of Glass: Diminuendo and Crescendo in Blue" was fabricated in the PGC studios by Jill Reynolds and Daniel Spitzer, artists from Beacon, NY. The installation covered 1,500 sq.ft. and used approximately 1,300 blown glass forms to illustrate Pittsburgh's three rivers. Aaron Stauber, President of RexxHall, said that leases in the office building increased after the project was announced.
Unfortunately, the building was sold and during renovations the installation was removed and placed in storage.
