Conclusion

The introduction of A913 nearly two decades ago has expanded architects' and engineers' structural options considerably, particularly but not exclusively on larger projects. The entry of a domestic manufacturer into the A913 field, moreover, creates not only healthy competition but the possibility of relief from supply-chain uncertainties and logistical complications, factors that have always been important but are even more so in the post-pandemic economy. This circumstance implies that the gradual adoption of this material may accelerate throughout the American built environment.

Voelkle, reflecting on her team's experience with The Spiral, notes that “domestic sourcing of critical materials such as steel means the reduction of transportation time, which reduces the carbon footprint.” While BIG, as architects, rarely advise engineers and contractors about the details of steel purchases, she and her colleagues find that some clients more readily commit to domestic purchases for the sake of facilitating parts replacements, quality assurance, and facility inspections. That said, the European manufacturer can counter these advantages through longer experience with A913. With a material that generates such benefits, there are no bad choices.
