More than 31,000 square feet of slate -- quarried and supplied by Green Slate Mining/Micapel of Pompeu, Minas Gerais, Brazil -- was used for exterior cladding, interior walls, pylons, a water feature and benches. The panels employed for the cladding are extremely large, measuring 2 feet, 6 inches x 5 feet with a thickness of 3 cm.
“The architect picked the slate because it was green and 'healthy' looking,†said Paul Shand of SPS & Associates in Hudson, OH, the stone erector for the project. “It went well with the health museum -- there's only two in the country. There is also one in Washington, DC.â€
