East Coast Resiliency Project

ESCR is a $1.45 billion climate resiliency project that will provide flood protection and improve open spaces for more than 110,000 New Yorkers, including 28,000 residents in NYCHA housing. This is especially significant for neighborhoods in the ESCR project area that were severely impacted by Superstorm Sandy in 2012.

Amrize’s Ductal® Structural Engineered Solutions emerged as the optimal innovative concrete for this project. Its superior mechanical and durability properties compared to conventional concrete made it the perfect choice. Its fresh properties, oftentimes including self-consolidation, allow it to be an ideal match for field construction with prefabricated components. Its unparalleled strength, durability, and low permeability will ensure longevity and minimize maintenance requirements.

Ductal’s team commitment to excellence drove us to optimize our mix design to adhere to the highest standards of performance. Ultra-High Performance Concrete has excellent durability and resistance to damage from most environmental factors such as freeze-thaw cycles, chemical exposure, and abrasion. This means that structures made with UHPC can last much longer and require little to no maintenance over time, eliminating the need for replacement and associated environmental impacts.

To date, 40,000 tons of OneCem®, an Amrize Brand, and 5,000 tons of slag have been used in the ESCR section of the BIG U.  A tailored OneCem® blend was used in the walls to provide high structural strength — protecting the city from the surrounding Hudson River and East River tidal estuary — while another mix including slag is used to create parks and pathways.

In August 2022, the ESCR Project received the "Envision Gold Award" for sustainability from the Institute for Sustainable Infrastructure (ISI). The Envision sustainable infrastructure framework assesses project sustainability across five categories: Quality of Life, Leadership, Resource Allocation, Natural World and Climate and Resilience.

Ductal’s collaboration with IPC Resiliency Partners is making this project a blueprint for other waterfront cities in the US.
