RJ Lee Group became involved at Ground Zero, site of the September 11, 2001 attacks, early in the area’s rebuilding phase. Today, as experts with sensitivity to the area’s history, RJ Lee Group is completing the circle of work as it partners with a group of experts involved with the One World Trade Center Project.
RJ Lee Group’s work began at 130 Liberty Street, in 2002. Building owners retained RJ Lee Group to assess the environmental impact of structures damaged in the September 11th attacks. Following the catastrophic event and the subsequent collapse of the World Trade Center Towers, RJ Lee Group began to collect thousands of dust samples from various systems throughout the buildings. The samples were analyzed for potential contaminants including asbestos, heavy metals, PCBs, PNAs and dioxins-furans.
The RJ Lee Group team spent over three years at 130 Liberty Street in the arduous task of sample collection and monitoring. During this period, RJ Lee Group utilized its information technology department to build software that could be used during the sample collection process. RJ Lee Group also partnered with architects, engineers, toxicologists and medical professionals to conduct remediation studies that would lead to remediation protocols designed to ensure contamination-free conditions.
Today, reconstruction of Lower Manhattan’s World Trade Center site, with its signature office building One World Trade Center, is one of the most high-profile reconstruction projects underway in America. With its knowledge-base and history of work at Ground Zero, RJ Lee Group was a strong candidate for laboratory services in the building of the new trade center. When completed, RJ Lee Group will have contributed its services to the 1,776-foot One World Trade Center that features 2.6 million square feet of office space on 69 floors.
To ensure the durability of One World Trade Center, a unique concrete mix design was specified. iCrete, a technologically advanced patented concrete system that offers record strength, dramatic environmental benefits and cost efficiencies, was chose to provide the right concrete structure. RJ Lee Group is partnering with iCrete as the company’s laboratory for the analysis of mix design specifications. The iCrete product provides strengths up to 14,000 psi, which are the strongest levels ever poured in the history of New York. Ultimately 215,000 cubic yards of concrete will be utilized to erect the building.
With direction from the Port Authority of New York and New Jersey and New York City-based Tishman Construction Company, Collavino Construction is pouring iCrete at the below-grade portion of the project, which will accommodate loading zones, mail rooms, cooling tanks and most of the auxiliary services required for the building. RJ Lee Group is glad to be a part of the process that brings this area’s traumatic history full circle to a monument of American hope and pride.
