Sculpture Conservation, Outdoor Sculpture Conservation:
In September, 2010, a 12 foot tall, 9,000 pound sculpture in Portland, Oregon, a free-standing, monumental stone arch with joints of uncertain strength, had to be moved quickly and safely. The ability to turn the arch on its side was also a critical and challenging requirement. A design using expanding polyurethane foam and a steel space frame did the job safely. The project quickly became known as “Foamhenge.”
