432 Park Avenue at completion will be one of the tallest US-building structures with a roof height
exceeding that of both the empire state building and the New World Trade Center Tower 1. Large
concentrations of reinforcement in the structure required the use of SAS high performance systems. The
structure was deemed “un-buildable” without using SAS materials. The largest available rock anchor tie down the structure to bedrock to resist uplift on the structure. The primary tower columns consists of all SAS 670/800 thread bars, as well as the large boundary elements of the core shear walls were replaced with SAS 670/800 materials. Aiding the contractors with the schedule cycle, all columns and shear wall elements were provided prefabricated into cage modules for rapid construction in the field. Once again New York is
built with material from Stahlwerk Annahütte.
