High Steel Structures Inc. and Hirschfeld Industries, LP to Fabricate Structural Steel for the Tappan Zee Bridge
Two major U.S. steel fabricators have stepped up to take on one of the most significant transportation projects in the nation’s history.
High Steel Structures Inc. (an AISC/NSBA member and AISC certified fabricator) of Lancaster, Pa., and Hirschfeld Industries, LP (an AISC/NSBA member and AISC certified fabricator) 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.
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.
The approach steel package bid was submitted September 24, 2013, and awards were made to High Steel Structures and Hirschfeld Industries on November 11, 2013. 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 American Institute of Steel Construction 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.¾it 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 size¾a 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.
Submission Deadline Approaching for NSBA Prize Bridge Awards
NSBA is accepting entries for its 2014 Prize Bridge Competition, which honors significant and innovative steel bridges constructed in the U.S. The winners will be announced at the 2014 World Steel Bridge Symposium (WSBS), which will be co-located with NASCC: The Steel Conference in Toronto, March 26-28, 2014, at the Metro Toronto Convention Centre. Entries are due by December 31, 2013 and must be submitted online at www.steelbridges.org/PrizeBridgeAwards.

Decision Delta: The New Shenandoah River Bridge

Just an hour’s drive west from Washington, D.C., the new Shenandoah River Bridge stands in aesthetic harmony with its surroundings.
The project exists within a unique ecosystem where the scenic Shenandoah River valley boasts steeply rising wooded mountains, a diverse wildlife habitat, rolling farmland and quaint, historic towns. Not surprisingly, the region has evolved into a desirable getaway from the frenzy of urban life.
With the subsequent increase in traffic, the West Virginia Department of Transportation - Division of Highways (WVDOT) determined that the winding two-lane road that carried West Virginia Route 9 (WV9) through the valley was no longer sufficient. In September 2009, it revealed the design for a new alignment: a four-lane divided highway using a bridge over the Shenandoah River. At the crossing location, the proposed grade was nearly 200 ft above the river, and the overall bridge length would be nearly 1,800 ft. While there are no navigation requirements for the river, the environmental constraints for the project and the relatively high cost of substructure units located in the valley dictated that the main span be approximately 600 ft in length. To accommodate these constraints, a three-span continuous deck truss configuration (400 ft - 600 ft - 400 ft) with short plate-girder approach units was initially selected during the design phase.
In early October 2009, WVDOT modified the procurement from design-bid-build to design-build and instructed contractors that they could bid the as-designed truss or develop and bid a different structure type, providing they addressed the following criteria:
- The chosen substructure locations for the deck truss bridge generally must be used, with very limited latitude.
- The established horizontal and vertical alignment could not be changed.
- Alternatives that required increased amounts of disturbance to the gorge slopes would not be considered.
- The use of a causeway or cofferdams, other than as shown on the plans for the as-designed bridge and/or in the Section 404 (of the Clean Water Act) Permit, would require re-permitting.
- The design must comply with all previously established environmental commitments.
Following concept approval, structural engineer HDR Engineering developed a delta frame design that delivered significant savings compared to proposals for more traditional designs and also resurrected a tried-and-true form that had been largely forgotten since the 1970s.
To learn more about this uncommon design resurrected by the new bridge, you can read the article from the December 2013 issue of MSC (available now!).
NYU-Poly Student Steel Bridge Performs Double-Duty
Proving that innovative engineering (and steel) can overcome specific weight, the above photo shows the Polytechnic Institute of New York University’s student steel bridge from this year’s ASCE/AISC Student Steel Bridge Competition supporting the university’s student concrete canoe from this year’s ASCE Concrete Canoe Competition. The Student Steel Bridge Competition challenges student engineers from across North America to build their own small-scale pre-designed and fabricated steel bridges and tests the load-bearing capacity of the actual bridges built to this year’s specifications.
Here’s a close-up view of the steel bridge fabrication, performed by the students:
The 2014 National Student Steel Bridge Competition will take place at the University of Akron, May 23-24. For more information, visit www.aisc.org/steelbridge.
Federal Budget Agreement: Good News (at Last) for Public Agencies
Daniel Hartinger of FaegreBD in Washington, D.C. has provided some valuable insights on the current federal budget agreement.
According to Hartinger, “Assuming the House and Senate are able to pass the budget resolution negotiated by Sen. Patty Murray (D-WA) and Rep. Paul Ryan (R-WI), the agreement would signal a return to a budgeting process dominated by the Appropriations Committees rather than Continuing Resolutions (CRs) negotiated by leadership (a return to the normal process). Once passed, the House and Senate will reissue revised subcommittee level appropriations allocations (302(b)) as soon as possible, in order to prepare to pass an omnibus appropriations bill before January 15, 2014, when the current CR expires. Additionally, having an already agreed upon Fiscal Year (FY) 2015 spending level will potentially help the House and Senate to move FY 2015 appropriations bills on a normal schedule, with final bills passed in advance of the end of the fiscal year.
