Obayashi also has an established record outside of Japan, dating back to 1962 when the Company became the first Japanese general contractor to take on an overseas construction project. The Company later moved into the United States, and in 1979 became the first Japanese construction company to win an order from the San Francisco City Government to build a sewer system. In the 30 years since that project, Obayashi has continued its business activities in the United States, playing a role in many high-profile large-scale projects, from the seismic retrofit of the Golden Gate Bridge to the bypass bridge over the Colorado River, downstream from the Hoover Dam, icon of the New Deal.
