First-of-a-Kind: PANYNJ Leverages Unique Investigate-Design-Build Delivery to Restore Salt Damage at World Trade Center
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.
Four Learning Objectives:
- Discover the Owner’s evaluation of delivery methods process and analyze the decision criteria for use of design-build using the WTC project for reference
- Translate PANYNJ’s extensive experience related to Design-Build for new construction of world class facilities into how to effectively manage and deliver Design-Build for rehabilitation projects
- Assess the risks presented on repair projects and how the are managed through strategic use of contingencies and allowances, specifically for portions of scope that have variable quantities and potential scope changes based on variability or as-found conditions.
- Acquire knowledge regarding the benefits of Design-Build delivery to develop solutions and execute repair and restoration of existing structures.
