American Steel Bridge Industry is Ready to Meet the Nation’s Infrastructure Needs

Article provided by the American Institute of Steel Construction and the National Steel Bridge Alliance.

“We’re excited that funding is finally becoming available to rejuvenate and improve America’s bridges. The American steel fabrication industry and our domestic steel mills are ready and able to meet our nation’s infrastructure needs,” stated Charles J. Carter, SE, PE, PhD, president of the American Institute of Steel Construction and executive director of the National Steel Bridge Alliance.

Carter will be discussing the current state of the fabrication industry during a special session at this year’s NASCC: The Steel Conference in Denver from March 23-25.

“Last summer, as a result of the ongoing pandemic, the structural steel industry experienced longer than normal lead times and extended delivery schedules, just like almost every construction material,” Carter explained. “Fortunately, the steel industry has almost fully recovered. And whether it’s raw steel or fabricated product, our members have the personnel, capacity, experience, and skill to successfully complete all of the anticipated projects.”

Steel Industry Has Capacity To Complete Anticipated Projects

Thanks to Buy America provisions, steel plate and structural steel used in bridge construction are widely available from domestic steel mills, so not subject to the current port delays most supply chains are currently experiencing.

Nucor Steel Mill

Nucor Corporation is adding a blast and prime line, with an annual capacity of approximately 120,000 tons, in Brandenburg, Kentucky (note – above picture is of the Nucor Steel Gallatin Plant).

Further, to accommodate the expected increased demand from the recently passed infrastructure bill, the steel industry is rapidly adding capacity, such as the $1.7 billion plate mill now under construction in Kentucky and additional upgrades being made by multiple steel producers.

According to steel mill representatives, the industry has the capacity to support both the current and expected future demand for steel. And on the fabrication side, many companies have upgraded their equipment, improved their automation, and increased their staffing in anticipation of increased bridge projects due to the new infrastructure bill.

 

Bridge Owners Look to Steel for Answers

To address the high number of structurally deficient structures, bridge owners and designers are looking to steel to fix our nation’s infrastructures. Why steel?

  • Due to the light weight of steel, cost savings can be significant by using smaller abutments, local crews, and lighter equipment.
  • Steel can compete and save costs when compared with nearly identical concrete structures.
    • Learn how Audrain County, Missouri saved 19 percent by using steel in a side-by-side comparison of a steel versus concrete bridge.
  • Steel bridges also have long lives, decreasing the need for replacement.
    • Learn about the innovative press-brake tub girder system – it has a life expediency of over 100 years, with the first 60 of those years being maintenance-free.
  • Steel bridges can be designed with prefabricated elements which provide a simpler installation and time savings.
    • Learn how a prefabricated steel truss bridge was quickly erected to reconnect a community decimated after the Woolsey fire that swept through the Santa Monica Mountains.
  • Habitat protection and environmental enhancements are major benefits of using buried steel bridges.
  • Steel is the world’s most recycled material and is infinitely recyclable, so it can be repurposed from one bridge project to another.
    • Learn how Muskingum County, Ohio saved $51,000 in superstructure costs by repurposing steel beam for the replacement of the Green Valley Road Bridge.

 

Raw Materials Only Fraction of Bridge Cost

While availability and lead times were the hot topic last fall, today’s discussions focus more on the escalated pricing for all raw materials. John O’Quinn, president of High Steel Structures and chair of NSBA’s Market Development Committee, is quick to point out that raw material pricing represents only a fraction of the total cost of a bridge.

Steel Bridge Pricing

Raw material pricing represents only a fraction of the total cost of a bridge.

“You can not simply look at the change in plate pricing to fully gauge the cost of a bridge,” he explained. “We manage highly impactful variables including labor, materials, coating systems, erection, and even the timing of the project to best deliver bridges at a cost and schedule that meets each owner and project’s needs.”

Owners and designers with specific concerns about pricing and availability should contact either their regional NSBA representative or one of AISC’s more than 350 certified steel bridge fabricators.
