During construction of the new World Trade Center (WTC) in 2012, Hurricane Sandy inundated the worksite with 200M gallons of brackish water. The water was rapidly removed but the salt remained embedded, causing damage across the iconic structure’s first decade of service life. The saltwater caused corrosion and service life reduction along the lowest levels of WTC approximately 70 feet below grade. Beginning in 2021, the Port Authority of New York New Jersey (PANYNJ) embarked on a multi-year project aimed at remediating the damage and restoring structural capacity for WTC’s intended 100-year service life. Based upon the varied extent-of-damage conditions which drove the need for extensive investigation as a first step, PANYNJ’s desire for cost certainty and need to manage schedule constraints in a complex working environment, design-build delivery was selected. Learn detailed information on the project scope and implementation focusing on the benefits gained using DBIA’s updated Universal Best Practices. Explore the many lessons learned by PANYNJ and the Structural-Dewberry Design-Build Team, and how they can be applied to future projects to drive success through Design-Build-Done-Right®.
