Move over, Willis Tower. The Council on Tall Buildings and Urban Habitat (CTBUH) issued its official ruling Tuesday: New York’s One World Trade Center unseats the Chicago skyscraper as the tallest building in the Western Hemisphere. The new tower’s symbolic height of 1,776 feet was called into question when a design change suggested it might achieve that elevation only through the addition of a removable broadcast antenna. CTBUH counts only structural elements that are considered an integral part of the building’s aesthetic. It was designers Skidmore, Owings & Merrill’s assertion that 1 World Trade Center’s communications equipment represented a permanent architectural feature that persuaded CTBUH to affirm its height. The bottom point of the building was also in dispute. Without antennae, 1 World Trade Center is 1,368 feet tall — the height of the original World Trade Center tower destroyed in the 2001 terrorist attacks on Sept. 11. Chicago’s Willis Tower (also an SOM building), still commonly referred to as the Sears Tower, stands 1,451 feet tall — 1,729 feet tall with antennas. It was the tallest building in the world until 1996, when the Petronas Twin Towers in Kuala Lumpur, Malaysia, won CTBUH’s recognition.

International Property Developers (IPD) has renewed plans for massive developments around Chicago’s Old Main Post Office. IPD bought the structure in 2009 for $40 million and has been working with Chicago-based architects Antunovich Associates on a plan to surround the massive building, which has almost as much interior space as Willis Tower, with three new towers. The first phase, expected to take 5-7 years, would be a 100-story tower with 800,000 square feet of retail, 2,900 residential units, and 525,000 square feet of office space. Following that, a second 2,000-foot-tall tower would go up, adding 3,500 residential units, 1.5 million square feet of office space, and 920 hotel rooms. The project’s 5,700-space parking garage, rising six stories, would be built during the first phase, project representatives said at a public meeting Tuesday. Those numbers are daunting, but so is the original acquisition, after all. They would need a sizable anchor tenant to lend the proposal some economic legitimacy. A casino, perhaps? Aldermanic support for the $3.5 billion development has apparently not waned, nor has scrutiny of its decidedly suburban sensibility and so-far uninspiring design.
Scrap your afternoon plans and take an amazing aerial tour of Dubai, instead. Photographer Gerald Donovan has created an interactive panorama of the city as seen from the top of the world's tallest building, the Burj Khalifa for the Hamdan Bin Mohammed Bin Rashid Al Maktoum International Photography Award. The view was taken from the top of the tower, some 2,722 feet above the street, reached by climbing nearly 660 feet through the Burj Khalifa's enormous spire. Users can pan around and zoom in to observe the surrounding cityscape with amazing detail. To achieve the stunning effect, Donovan stitched 70 photographs together, each a whopping 80 megapixels, to create a single 2.5 gigapixel panorama. [Via The Telegraph.]
Hurricane Sandy is bearing down on New York and New Jersey, and the current 55 to 60 mile an hour wind gusts tearing through Central Park have already taken their toll on Manhattan's starchitecture, partially collapsing the construction crane at Christian de Portzamparc's supertall One57 tower on West 57th Street. The storm snapped the boom of the crane at the summit of the 95-story, 1,004-foot-tall residential tower, which now dangles precariously over the streets of midtown Manhattan. The scene on the street is still developing, but NY1 reports that the crane could become off-balance causing a further collapse. Surrounding streets have been closed and emergency crews are on the scene. [Via Observer & Curbed.] Elsewhere in New York, wind gusts are picking up. The storm surge along the East River has sent water rushing into low-lying areas of the East River Esplanade and FDR Drive. In Brooklyn, AN stopped by the Gowanus Canal (photo below) at approximately 1:30pm to find a higher-than-normal water level, but no significant flooding in the area. As Sandy moves closer to land, winds and rain are expected to increase and the storm surge to rise.
Bjarke Ingels, architect of mountains, now has set his eyes on Everest. The New York and Copenhagen-based architect's firm BIG has been tapped by the Rockefellers to design one of the world's tallest buildings at 1,929 feet for a new commercial development in Tianjin, China, a city of nearly 13 million people. Ingels revealed a cryptic, fog-shrouded rendering of the tower on his web site—indicative of the scarcity of detail yet released on the tower—but this being the information age, AN found more information and views of the tower on a clear day. BIG is working with HKS Architecture and Arup to design the $2.35 billion Rose Rock International Finance Center set within an SOM-designed master plan for the Tianjin Binhai New Area Central Business District. The new commercial neighborhood to the southeast of Tianjin replaces a formerly industrial peninsula with a mix of high-rises, historic sites, and parks anchored by a high-speed rail station and helps to connect it to the coast. Rose Rock Group, founded by Steven C. Rockefeller Jr., Steven C. Rockefeller III, and Collin C. Eckles, held a ceremonial groundbreaking on December 16, 2011 and is promoting the new tower as a key to transforming Tianjin into "the financial center of Northern China." Renderings show a terraced pyramidal tower with a palpable vertical thrust and clear reference to the Art-Deco stylings of its inspiration, the Rockefeller Center in New York. Just as the Rockefellers built ambitiously skyward in New York 80 years ago, Ingels said in a statement, "The Rose Rock International Finance Center will be to the contemporary Chinese city what the Rockefeller Center was to the American city of the 1930s: an architectural landscape of urban plazas and roof gardens designed to stimulate and cultivate the life between the buildings." Only this time, over a thousand feet higher.
A "supertall" building is one which tops out at over 1,250 feet. Right now, there are 18 completed supertall buildings and 21 under construction. Chicago-based architects Skidmore, Owings, and Merrill (SOM) will break ground on Tuesday on the 1,740-foot-tall CTF Tower in Tianjin, China. It will be the tenth supertall building to begin construction for SOM, the most of any firm in the world. The building is a carefully-crafted design which deliberately merges structural challenges with program and form. The mixed-use tower in the Tianjin Economic Development Area, an area planned for new growth, has retail at the base, topped with offices, 300 residential units, and a 350-room, 5-star hotel. "The functional aspects of program were integrated with the structure," said SOM design partner Brian Lee. "And the form was also developed alongside the structural scheme." Larger floor plates are needed for the office spaces, which are placed near the base of the building. Residential units with smaller floor plate are at the top. The gentle curves of the building and the large, sloped, concrete elements form a "mega-column," which acts as an external frame. Environmental conditions also affected the final design. Wind slots, a porous crown at the top of the tower, and a gradiated opacity toward the higher floors all help to decrease wind loads, and the corners are rounded to prevent a vortex effect on the back side of the building.
It's Parametric. ArchDaily posts an intriguing project from Bucharest, Romania: the Hexigloo pavilion designed by architecture students. Under the supervision of instructors Tudor Cosmatu, Irina Bogdan, and Andrei Radacanu, 55 students learned basic parametric design principles and over the course of one week built a striking honeycomb structure of cardboard funnels. Spantastic. The Guardian reports the opening of the world's longest sea-crossing bridge that spans the Jiaozhou Bay in China. After four years and roughly £1.4 billion, the bridge makes possible commuting between cities Qingdao and Huangdao in a region southeast of Beijing. Look forward to another, even longer, bridge opening in 2015 that will connect the Guangdong province to Hong Kong and Macau. Supertallest. The Council on Tall Buildings and Urban Habitat awarded Adrian Smith an honor of lifetime achievement for his work in the realm of the supertall. Bustler highlights Smith's work on some of the world’s tallest completed buildings: Dubai’s Burj Khalifa, Nanjing’s Zifeng Tower at Nanjing Greenland Financial Center, Chicago’s Trump International Hotel & Tower, and Shanghai’s Jin Mao Tower while at Skidmore, Owings & Merrill.
