WTC Oculus

Description

One of New York City’s most iconic projects, the World Trade Center Oculus is as visually striking as it is functional, serving as a transportation hub and high-end shopping mall in the heart of lower Manhattan. In 2012, Skanska Koch was awarded a $204 million contract to fabricate and erect 1,000 tons of structural steel consisting of portals, arches, and rafters that combine to give the Calatrava-designed Oculus its unique shape. This structure serves as the main access point to the PATH commuter train at the World Trade Center Transportation Hub as well as subway lines, a critical link between lower Manhattan and New Jersey serving 200,000 commuters daily.

Scope

AEIS applied welding and non-destructive testing (NDT) expertise on this project. Our team anticipated non-conformances while coordinating day-to-day activities with project personnel. AEIS determined the quality and compliance of project materials and activities in reference to approved specifications, standards, and codes. This in turn, enhanced project-owner confidence in the long-term structural integrity and safety of the WTC Oculus.

• SNT-TC-1A Level III NDT technicians performed a level III consultation. This included preparation of ultrasonic testing procedures for non-standard joint configurations and the development of qualification samples and protocol for qualifying personnel. SNT-TC-1A Level II NDT technicians performed ground penetrating radar, magnetic particle, and ultrasonic testing inspections.
• AWS-Certified Welding Inspectors performed structural steel welding inspections. Radiographic, mechanical, chemical, and metallurgical testing and analysis was utilized for the qualification of materials, welding procedures, and personnel.
• Codes utilized: AWS D1.1:2008, AWS D1.5: 2008, AWS D1.6: 2007
