Written by Jan Boston Features State-of-the-Art Security Brilliant splendor describes New York’s newest skyscraper, the 34-story International Gem Tower, which opened this summer on West 47th Street in the heart of the Diamond District. Designed to cater to the needs of the gem industry, the building features state-of-the-art security including iris scanners, tracking technology, 350 cameras and secure underground delivery bays. G4S served as the security consultant; the Olympics are among their clients. Internation Gem Tower The building has been certified as a U.S. Foreign Trade Zone – allowing duty-free import/export within the building. The postmodern building was designed by Skidmore, Owings & Merrill, LLP (SOM) New York. The diamond district was their creative inspiration with angular geometry and the cut of the building used to design a striking geometric building. The focus was on the skin of the building, and SOM chose Starlight 7J stainless steel, manufactured by Tsukiboshi Art Co., Ltd. of Japan and distributed in North America by Contrarian Metal Resources, Allison Park, PA. Starlight 7J is a uniformly textured stainless steel finish designed for architectural applications with excellent finish consistency resulting in panel-to-panel matching. Internation Gem Tower The stainless steel adds to the impact of the curtain-wall, transforming the façade, explained SOM’s Todd Shapiro. “The stainless steel material captures and refracts light and the panel texture heightens the visual effect,” he added. The tower features embedded hexagonal shaped panels on a clear glass curtain wall as well as unobstructed 360’ views, creating an abundance of natural light. The project like many since 2008 suffered delays as a result of America’s sagging economy. Construction resumed in April of 2011 largely due to the efforts of Gary Barnett, President of Extell Development Company, the developer of the project. Barnett began his career in Antwerp as a diamond dealer and that knowledge was instrumental in the development of the building. Internation Gem Tower Another distinction is that it is actually two buildings in one. The fourteen floors at the upper portion of the tower have their own entrance and are being leased to more Class A office tenants; their address is 55 West 46th Street. The lower twenty floors are reserved for the diamond industry. There is a public park behind 1166 Sixth Avenue that allows a great perspective of the tower throughout the day. The shimmering 680,000 square-foot building was skinned by Permasteelisa North America who created multiple prototypes and mock-ups to make sure the desired results were achieved. “The only challenge we faced was to ensure we had no oil canning, over the length of the larger panels, and we solved this by using three vertical stiffeners which resulted in extremely flat panels,” explained Larry Platman, PNA Project Manager II. “The Starlight 7J was a great success,” he added. Internation Gem Tower Tishman Construction served as the general contractor. The largest presence is the Gemological Society of America which has purchased three floors, approximately 65,000 square-feet. The Gem Institute is bringing their Madison Avenue educational campus and their Fifth Avenue laboratory to the tower. The standard-setter for the jewelry industry has a presence in 14 countries which includes additional campuses and laboratories. Another major tenant, Gulayar Group (Turkish) has purchased the first three floors and will develop a modern jewelry exchange. The International Gem Tower has been referred to as A Gem of a Tower. # # # Press release written by: Jan Boston 414-331-0914 This email address is being protected from spambots.
