3 WTC fully open to the public – 10,000 glass panels later
With the completion of the tower in 2018 came the opening ceremony in June of this year. Full access to the lobby and transit hall have just been permitted after scheduling conflicts have all been resolved. You can now come in from the Fulton St station by train and walk through the Oculus and up into the transit hall of 3 WTC, all in one continuously conditioned space.
We are proud to have worked with Tishman and Mariani Metal on this full-service project (calculations-shop-fabrication) and have designed and engineered the transit hall/lobby curtain walls with blast-resistant building design throughout. Although LED worked together with Mariani Metal to complete almost all metal-related fixtures and assemblies in the transit hall, (w/ calculations and shop/fabrication drawings for these items) the brunt of the work relied on bomb-resistant glass wall design for the massive curtain walls and top hung 3-level glass floor system with intermediary bridges. The use of Duplex Stainless Steel was a key design element when engineering the curtain walls, mullions, transoms, brackets, and even nosing connections. Careful collaboration between Mariani and LED also allowed for a smoother and faster fabrication process which allowed for more installation time on-site.
