Tappan Zee Constructors LLC, comprised of Fluor Enterprises, Inc., American Bridge Company, Granite Construction Northeast, Inc., and Traylor Bros., Inc., formed a joint venture that combines local, national, and international experience to design and construct the Tappan Zee Bridge. The $3.1 billion innovative design of the 3.1-mile twin span cable-stayed bridge with angled main span towers is the single largest bridge construction project in New York’s history. The bridge will revitalize the existing Governor Malcolm Wilson Tappan Zee Toll Bridge that connects Rockland County to Westchester County over the Hudson River.
Tappan Zee Constructors LLC received an executed contract and notice to proceed (NTP) on January 18, 2013. The project is currently underway, and the team has established offices in Tarrytown, New York.
Construction will take approximately five years with completion projected for 2018; and the construction schedule will benefit from utilizing unique heavy lifting equipment that Fluor and its partner American Bridge own and had custom built for the San Francisco-Oakland Bay Bridge project.
The existing Governor Malcolm Wilson Tappan Zee Toll Bridge connects Rockland County to Westchester County in the Lower Hudson Valley. It is a vital transportation link over the Hudson River. However, the 58-year-old-structure was not designed to cope with peak traffic, which has exceeded the original design specifications of 100,000 vehicles. Today the bridge serves approximately 138,000 vehicles per day and as a result, travelers often experience delays, higher incidences of accidents, and increased safety risks, as there are no lanes or shoulders for emergency or disabled vehicles.
Initial interest in replacing the Tappan Zee began back in 1999 with 430 meetings held and $88 million on studies spent before this most recent bid process. Building a new crossing between Rockland and Westchester has become a signature project since the Obama administration fast-tracked it for review in October 2011. The bridge had come to symbolize how infrastructure projects could help revitalize New York’s economy.
The $3.1 billion construction contract is one of the largest in state history and the single largest bridge project in New York’s history. The full cost of the project will approach $4 billion after $500 million to $800 million in environmental mitigation, management and financial costs are added. It is the state’s first application of its recently enacted design-build legislation and has produced substantial savings relative to the $5.2 billion estimated cost. The winning Tappan Zee Constructor’s bid was the lowest bridge proposal and saved taxpayers and users approximately $1.5 billion. As part of a new law specially created for the project, the design-builder will be financially responsible for cost overruns and delays.
The Fluor front-end engineering and design team developed a unique and innovative structure that reduces the weight of the bridge and minimizes the number and size of foundations required. The design solution also utilizes a shallow superstructure and a 350-foot long-span design to minimize the number of piers and provide a sleeker looking bridge that enhances the view corridors within the lower Hudson Valley. The main span is a composite deck cable-stayed structural system with outwardly inclined main span towers that create an iconic look and accommodate future transit loads.
The design will allow for dredge quantities to be reduced from 1.8 million cubic yards to less than one million cubic yards, lessening environmental impacts, costs, and schedule durations. In addition, the construction schedule will benefit from utilizing unique heavy lifting equipment that Fluor and its partner American Bridge own and had custom built for the San Francisco-Oakland Bay Bridge project.
Additionally, the Tappan Zee Bridge Project has been hailed as a job creation opportunity for New York State. Tappan Zee Constructors joint venture is committed to contracting local and regional companies and labor.
