Oakland City Hall, 1 Frank H Ogawa Plaza, Oakland, CA

With the threat of earthquakes on the rise in California, CGI Preservation of Beverly Hills, CA, stepped in to fit the Oakland City Hall with protection against these natural disasters. To accomplish this complete seismic retrofit, they installed a milestone base-isolation system and placed an iron frame within the original structure. CGI then worked to achieve a complete restoration of the interior and exterior marble. Blending salvaged and original stone, they then honed the surfaces for a clean, new look.
