Marcel Mächler (Twin Peaks, Calif.) recently completed a major milestone in the stone-carving work at the new federal courthouse under construction in downtown Los Angeles. Mächler is working in close collaboration with Skidmore Owings & Merrill, the architect of the building. He hand-carved a 4.5-ft.-diameter federal seal as an 1.5-in. deep bas-relief in Indiana limestone. The carving was executed as a first-in-place, on-site creation and took nearly six weeks. The master stonecarver and scultor recently completed other projects at the Orange County Performing Arts Center (Costa Mesa, Calif.), Crystal Bridge Museum of American Art (Bentonville, Ark.) and Soka University of America (Aliso Viejo, Calif.)
