My bad. I missed the first hour of the tour led by Osamu Sassa and Mary Dietz. Sassa was the project architect for seven years for the many Maki projects in New York. Dietz represented Silverstein Properties. Archtober minions were out in force, so I will cede my blog space to those who actually enjoyed the presentation. Nonetheless, Benjamin and I had a wonderful post-tour conversation with Sassa. We both noted how much 4 WTC resembles the work of Edward Larrabee Barnes. Sassa had Barnes as a critic at the GSD, and expressed a reverence for him—and shared our sense that his contribution to the tropes of skyscraper design is under-recognized.
Cynthia Phifer Kracauer, AIA, is the Managing Director of the Center for Architecture and the festival director for Archtober: Architecture and Design Month NYC. She was previously a partner at Butler Rogers Baskett, and from 1989-2005 at Swanke Hayden Connell. After graduating from Princeton (AB 1975, M.Arch 1979) she worked for Philip Johnson, held faculty appointments at the University of Virginia, NJIT, and her alma mater.

Joseph E. Brown, landscape architect and chief innovation officer of Aecom, will design the park, which will include 40 trees and shrubs, a curving balcony, several walkways, and a 300 foot long "living wall" composed of Japanese spurge, Baltic Ivy, among other plantings. It will also feature a grand staircase behind the church furnished with wooden benches and seating tiers.Much of the design is subject to change, but construction on the park should be well on its way by early next year. The new St. Nicholas Church will barely resemble its former home that was destroyed on September 11th. The new structure will rise on a large bulkhead to cover the vehicle security center on Liberty Street. In stark contrast to the simplicity of the original building, the new structure gives a nod to the architectural heritage of Byzantine churches in Istanbul: the Hagia Sophia and the Church of the Holy Savior in Chora. According to the Times, Calatrava will design a dome with 40 ribs just like the Hagia Sophia, and detail the interior with "alternating bands of stone on the corners" which will "echo the walls of the Chora church." This decision to pay homage to the architectural tradition of religious institutions in Turkey is not only an aesthetic one. Many of these churches became places for Islamic worship at different points in history, and tailoring the design after these historic structures has greater and more meaningful implications about religious tolerance. Several years ago, protests ensured when a plan for an Islamic community center and mosque surfaced. The Greek Orthodox Archdiocese struck a deal with Port Authority to lease the site for 99 years in exchange for allowing them to build at their original location on 155 Cedar Street.
Seven tons of glass and steel clad a structural stainless frame on the Western Hemisphere’s tallest building.Brooklyn-based metal fabrication company Kammetal and DCM Erectors of New Jersey were selected to fabricate and install the crowning beacon atop the spire on 1 World Trade Center. The fabrication team executed SOM’s design for a dynamic and complex adornment to one of the country’s most anticipated buildings, along with the help of engineers at Buro Happold to ensure safety at 1,776 feet. To craft a 15-ton, 50-foot beacon that accounted for thermal expansion and movement, Kammetal modeled and drew their designs in SolidWorks. The company’s team laser cut 48 triangular 316 stainless steel panels with ¼-inch thickness in a nondirectional finish to clad DCM’s square tubular steel frame. “Before we started the project, we had the structural frame 3D scanned to generate a point cloud,” explained Sam Kusack, president at Kammetal. “Because the structure was so dynamic—it contains zero right angles or reference points—we had to verify the conditions.” Once the angles were defined, multiple processes were employed to achieve the gentle curves of the cone. In order to ensure even bumping, or bending on a press break, the fabricators laser-scribed lines at every 1/8-inch along the panels’ interior. And to securely fasten each panel to the complex angles of the frame, Kammetal also devised a proprietary clip system that affixes each panel without obstruction. Clips that fell along certain angles could not be bent safely and had to be welded into place. To install tempered and laminated heat-soaked glass panels from Oldcastle, Kusack designed a proprietary vacuum panel lifting mechanism to adjust the panels without affecting the edges. “There’s a gap of just 3/8-inches, so it was the only way to handle the panels,” he told AN. The arm required a unique radius and capacity for strength to pick up each panel in a balanced manner and evenly align the gaps. Custom gaskets fabricated in London seal the glass from the elements. Kammetal also realized SOM’s original design for a rainscreen, which serves as a ventilation component. The beacon houses various mechanicals, including FAA lighting, so slots were laser cut to allow for air-cooling. To install the beacon, DCM Erectors fabricated a series of frames, supports, platforms, and transportation devices to safely place the beacon on top of the spire. “The owner of DCM invented a lot of gear and technology to realize this installation,” Kusack marveled. For example, a holding location was constructed at 1,700 feet to assemble the final interior and exterior components that all had to be raised an additional 70 feet so the apex could be lowered into place.
