Public sector infrastructure construction has been adversely impacted by recent shocks and stresses associated with global change, conflicts, and supply chain breakdowns. To address these challenges, this article presents novel methodologies to quantify past project delays and anticipate potential future disruptions from global shocks. These methodologies are then applied to over 2,000 projects executed by the US Army Corps of Engineers between 2011 and 2021. The results show that cost and time overruns in 2021 are double the baseline amount observed in the last 10 years. In some districts, a greater than 50% reduction in the number of contractors is also observed, despite an increased volume of work. Further, this article finds that many projects significantly rely on Russian-sourced minerals, suggesting that these challenges will likely accelerate as commodity scarcities from the Russia-Ukraine War unfold. This early-stage intelligence could significantly improve supply chain resilience in an increasingly unstable world.
