Moving a two-and-a-half ton steel sculpture is no simple feat, and it’s even harder when you have to plop it on top of a six-story building.

But the Southern California Institute of Architecture did just that recently with “Earthwave,” an 18-foot by 18-foot artwork that was designed by the late architect Lebbeus Woods (though it was not built until SCI-Arc took on the project last year).
“Earthwave” was transported from its home at the Arts District’s Joel Bloom Square and placed, via crane, onto the roof of developer Tom Gilmore’s building at 425 S. Main St. (Gilmore is also a SCI-Arc trustee). While the public won’t be able to access the structure up close anymore, “Earthwave”will be viewable from the Spring Street Park, according to SCI-Arc.
