The sole bid received for construction of the self-anchored suspension bridge in new east span of the San Francisco/Oakland Bay Bridge was about US$1 billion more than client Caltrans’ US$740 million estimate. A joint venture of American Bridge, NS Bridge and Fluor Enterprises submitted two prices: US$1.8 billion to use domestic steel and US$1.4 billion for an alternative with foreign steel. “Buy America” rules allow steel from elsewhere if the total bid using domestic steel exceeds the lowest based on foreign steel by more than 25%. Here the differential is 28.57% and so the foreign steel bid stands.
