Geotechnical consulting firm Shannon and Wilson based in Seattle, Washington was involved in the foundation engineering for a 360 ton sculpture by Michael Heizer at the Los Angeles County Museum of Art (LACMA). The giant granite boulder sits over a depressed ramp to the La Brea Tar Pits. The sculpture is entitled ‘Levitated Mass’. I’m reminded of a quote by Richard L. Handy:
Virtually every structure is supported by soil or rock. Those that aren’t either fly, float, or fall over.
