Cascade - Prince Kuhio Jonah Kalaniana'ole Federal Building


The General Services Administration’s Art in Architecture program seeks to enhance the understanding and appreciation of the public art it has installed in federal buildings across the United States. The Cascade monumental fountain sculpture was installed at the Prince Jonah Kuhio Kalanianaole Federal Building and US Courthouse (PJKK) in 1977 and, due to the combination of aggressive environment and water falling over the concrete and coral aggregate composition, has deteriorated to a potentially dangerous extent.

Surveying, engineering, and 3D imaging firm, Sam O. Hirota, Inc. was hired to digitally assess the condition of the sculpture to ensure its continued enjoyment by the public. The firm used a creative combination of 3D imaging sensors, powerful custom-built computers, and innovative software to produce virtual 3D models of the fountain that can be used as the basis of repair, restoration, 3D printing, and other conservation activities.

SOH was honored to receive an American Council of Engineering Companies of Hawaii Grand Conceptor Award and a Historic Hawaii Foundation Honor Award for its 3D documentation work.
