High Steel Structures of Lancaster, Pa., and Hirschfeld Industries of San Angelo, Texas, have each been awarded a contract to fabricate structural steel for the approach spans of New York’s new Tappan Zee Bridge. The project is the largest transportation design-build project to date in the United States and one of the largest construction contracts in New York State history.
The New York State Thruway Authority awarded a USD 3.142B contract to design and build the project to Tappan Zee Constructors (TZC), a consortium including Fluor Enterprises, American Bridge Company, Granite Construction Northeast, and Traylor Bros.
Fluor Enterprises is TZC’s lead contractor for sourcing the structural steel. High Steel Structures and Hirschfeld Industries teamed together to bid the project due to the massive size and scope of the steel production. The project was divided into two steel packages: one for the approach steel, totalling nearly 100,000 tons; and another for the main span cable stay steel, totalling approximately 10,000 tons. Each fabricator will produce approximately half of the steel under separate contracts and will provide portions of both the eastbound and westbound approach spans.
Steel deliveries are set to begin in October of 2014 and will continue into the first quarter of 2017.
