Highlighted by its unique barrel-shaped, three-story high atrium, the Michael D. Antonovich Courthouse is the largest civic building in the fast-growing High Desert region of Los Angeles County. Opened to the public in 2004, this four-story facility features 15 courtrooms with support facilities as well as a full basement containing a detention area, sally port and secure parking. The structure consists of a steel braced frame with concrete floors over metal deck. Our team worked closely with the precast-concrete vendor to support the cladding system for this building. It was used over most of the structure including outdoor trellises and patios, with glass cladding used to cover the barrel-shaped, three-story-high atrium at the main entrance.
