(an AISC/NSBA member and AISC certified fabricator) of Lancaster, Pa., and Hirschfeld Industries (an AISC/NSBA member and AISC certified fabricator), LLP 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 design-build transportation project to date in the U.S. and one of the largest construction contracts in New York State history.

After proposals were submitted in mid-2012, the New York State Thruway Authority awarded a $3.142 billion contract to design and build the project to Tappan Zee Constructors (TZC), a consortium including Fluor Enterprises, Inc., American Bridge Company, Granite Construction Northeast, Inc., and Traylor Bros., Inc. The design team working with Tappan Zee Constructors is HDR, Buckland & Taylor, URS, and GZA.


Shortly after the project was advertised, High Steel Structures and Hirschfeld Industries teamed together to bid the project due to the massive size and scope of the steel production.


Fluor Enterprises is TZC’s lead contractor for sourcing the structural steel. The project was divided into two steel packages: one for the approach steel, totaling nearly 100,000 tons; and another for the main span cable stay steel, totaling 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. The main span steel package has yet to be bid.


Steel deliveries are set to begin in October of 2014 and will continue into the first quarter of 2017. High Performance Steel (HPS) plate steel is being employed in the design. The primary material supplier for the project is ArcelorMittal USA.


“The award of the Tappan Zee structural steel contract to the team of fabricators High Steel Structures Inc. and Hirschfeld Industries, with material supply by ArcelorMittal USA, validates the fact that the United States steel construction industry has the capacity, capability, and collaborative spirit to meet our nation’s infrastructure needs,” stated AISC President Roger Ferch.


“We answered our industry’s call for leadership,” Hirschfeld’s Executive Vice President, John O’Quinn said. “Together we were able to provide the owner and design-build team with all the tangibles a project of this magnitude required, while mitigating their risks. The largest design-build bridge in U.S. history will utilize the two largest bridge fabricators in the U.S. — it just makes sense.”


High Steel Structures President Brian LaBorde said, “We are looking forward to working on this historic project, which demonstrates that fabricators in the United States have the capacity and capability to fabricate and deliver the massive quantity of structural steel required for a project of this size — a win for ‘Buy America.’


Located north of New York City, the new Tappan Zee Bridge will carry the Thruway, Interstate 87, and Interstate 287 over the Hudson River between South Nyack, Rockland County, New York and Tarrytown, Westchester County, New York. According to the Thruway Authority, the first span of the new twin-span bridge is scheduled to open in 2016, and the new bridge should be complete in 2018. The bridge will be designed and constructed to last 100 years without major structural maintenance.


In separate news, High Industries Inc., the holding company for High Steel Structures, recently announced the formation of High Structural Erectors LLC, a new company that combines the field operations of High Steel Structures and High Concrete Group LLC and provides erection services to the infrastructure, commercial, institutional and industrial markets. The company began formal operations as a High Industries affiliate in October.
