Assessing storm damage at the World Trade Center Towers 2, 3 and 4.

World Trade Center Towers 2, 3 and 4 (CAT 90-Sandy)



On October 29, 2012, CAT-90 Sandy hit New York City, inflicting widespread damage. Thornton Tomasetti was engaged by multiple insurers to assess storm-damage to World Trade Towers 2, 3 and 4.

Our multidisciplinary team of building experts assessed damage to building systems, specifically major mechanical, plumbing and electrical components submerged by the storm event. The assessment involved multiple stories below the street level and three separate, but interconnected, office towers that were under construction at the time CAT-90 Sandy struck.

We led the technical assessment of the damage and worked alongside forensic accountants, construction consultants and other building specialists, to provide information that sped the development of scopes of repair or replacement and measurement of costs for reinstatement. The collaborative team effort helped to conclude the three claims within eight months of the date of loss.
