Refined Designs and Construction Schedules Presented for Three World Trade Center TowersSep 06, 2007
World Trade Center developer Larry A. Silverstein and representatives of world-renowned architects Lord Norman Foster, Fumihiko Maki and Lord Richard Rogers gathered at 7 World Trade Center today to provide an update on designs and construction plans for the three World Trade Center towers being developed by Silverstein Properties. The three buildings will rise along the site’s eastern edge, forming what will be the heart of a revitalized Downtown Manhattan’s retail, transportation and office corridor. Construction on the three towers will begin next year.
The presentation of refined and more detailed architectural plans for towers 2, 3 and 4 were part of a larger World Trade Center development update today that included presentations by New York State Assembly Speaker Sheldon Silver, Port Authority of New York & New Jersey Executive Director Anthony Shorris, Lower Manhattan Development Corporation President Avi Schick and National September 11 Memorial & Museum President Joe Daniels.
In December 2005, Mr. Silverstein named Lord Foster and his firm Foster + Partners as the architect for 200 Greenwich (Tower 2). In May 2006, Lord Rogers of Rogers Stirk Harbour + Partners and Mr. Maki of Maki and Associates were named to design 175 Greenwich (Tower 3) and 150 Greenwich (Tower 4), respectively. Since that time, the three firms have worked in close coordination in a design studio created at 7 WTC as part of a unique team of architects, engineers, government planners and construction professionals.
“The World Trade Center Design Team is an unprecedented assemblage of design and engineering talents, all working toward the goal of creating a unified and inspired plan for rebuilding the WTC as a 21st-century urban center,” said Mr. Silverstein. “Over the past 16 months, some 120 men and women – from different design and engineering firms but sharing a single set of offices – have put to work their unique expertise. Working together around the clock has fostered a creative energy and level of collaboration rarely achieved on this scale in the architectural world. From a design perspective, each of the three towers is distinct, yet all three are architecturally compatible and work together seamlessly.”
Each tower has been designed to integrate with what will be newly-created pedestrian thoroughfares along the reconnected grid at Cortlandt and Dey Streets, the Memorial, WTC Transportation Hub, which is located between the towers at 200 and 175 Greenwich, and the rest of the Downtown community, including the Fulton Street Transit Center.
“This is a great day for all the residents, workers, visitors and emergency responders of Lower Manhattan,” said New York State Assembly Speaker Sheldon Silver. “A little more than six years ago, many believed that Lower Manhattan was finished as a major financial center. But, since that time, my community has overcome obstacles, dealt with setbacks and found new and innovative ways to keep the dream of full redevelopment alive. I applaud Larry Silverstein and his talented team of world-renowned architects, designers and engineers for their hard work in helping make this day a reality. Today, I am more confident than ever that the goal of a better, brighter Lower Manhattan – one that stands in tribute to all who have given their lives in the fight against hatred and terror – is on the horizon. We will get there together.”
Added Port Authority Executive Director Anthony Shorris, “Rebuilding at the World Trade Center site has come a long way in the last year, but there’s much more left to do. We’re focused on maintaining the tremendous momentum we’ve built for our signature projects – the Transportation Hub, Memorial and Freedom Tower – and on clearing the way for the creation of much-needed commercial space downtown.”
LMDC Chairmain Avi Schick said, “The redevelopment of the World Trade Center site will undoubtedly benefit from what is an all-star team of talented architects. Today we received a valuable glimpse of how the city’s skyline, and the financial district in Lower Manhattan, will be reshaped when the rebuilding is complete.”
Added National September 11 Memorial President Joe Daniels, “We have made remarkable progress on the Memorial & Museum this year. This winter, the steel columns of the Memorial will begin to rise from the site. As construction progresses and the Memorial & Museum experience is shaped, we are continually inspired by the growing number of people from across the country and throughout the world who participate in building the Memorial & Museum. The responsibility to build this tribute is a solemn one, extending to the family and friends of those whose loved ones were killed, to those who survived, and to the millions of people from around the world who will come to the World Trade Center site to learn about what happened on September 11, 2001 and in the aftermath. The National September 11 Memorial will be a symbol of our recovery from the attacks and will be at the heart of a rebuilt and revitalized Lower Manhattan.”
According to the agreement formalized in November of 2006, the Port Authority of New York & New Jersey, which is responsible for excavating and constructing a new set of slurry walls (a/k/a a “bathtub”) along the eastern portion of the site, will turn sites for Towers 3 and 4 over to Silverstein Properties in January 2008 and for Tower 2 in July 2008. Construction of the towers will begin immediately upon completion of the bathtub and will be ready for occupancy in 2012.
In anticipation of a January 2008 construction start for Towers 3 and 4, Silverstein Properties has already received bids for foundation work, and several more packages of work have been issued to the market seeking bidders. By the end of October, Silverstein expects to have 70 packages out for bid. By February of 2008, it is expected that contracts will have been awarded for several billion dollars worth of construction.
“All of our energy over the past months has been focused on being totally prepared to kick off construction as soon as we get control of the three tower sites,” said Janno Lieber, Director of World Trade Center Development for the Silverstein organization. “The design phase is now complete and the construction contracting phase is underway. We’re ready to start building the dynamic new commercial corridor that will meet the growing need for top-tier office space and enliven the Downtown streetscape as never before.”
In keeping with the standards established by 7 World Trade Center and the Freedom Tower, which were designed by David Childs of Skidmore, Owings & Merrill in collaboration with Silverstein Properties, the three Greenwich Street towers will be models of environmental efficiency, life safety and cutting edge technology. Silverstein Properties has committed to ensuring that each of the three towers will achieve at least a Gold rating, as did 7 WTC, under the U.S. Green Building Council’s Leadership in Energy and Environmental Design (LEED) program.
To follow are brief summaries of each Greenwich Street tower. More information and new images of the three designs are available at www.wtc.com.
200 Greenwich Street/Tower 2
Foster and Partners has designed a 79-story tower at 200 Greenwich. The tower, which will rise to 1,270 feet and topped by an 80-foot antenna, is bounded by Greenwich Street to the west, Church Street to the east, Vesey Street to the north and Fulton Street to the south. It will contain 138,000 square feet of retail (130,000 square feet at or above street level), 60 office floors, including a sky-lobby, that will total 2.3 million square feet, four trading floors and a 65-foot high office lobby.
According to Foster and Partners, 200 Greenwich Street’s sparkling glazed crystalline form and diamond shaped summit create a bold addition to the New York skyline. Arranged around a central cruciform core, the tower comprises four blocks containing light-filled, flexible, column free office floors that rise to the 59th floor, whereupon the glass façades are sheared off at an angle to defer to and address the Memorial Park. Giving the building its distinctive inclined summit as the second tower in the World Trade Center Master Plan, 200 Greenwich Street also acts as a symbolic marker of the location of the Memorial Park when viewed from any location. The upper floors contained within the summit provide the opportunity for sweeping views of the park, the river and the city.
A continuation of Foster and Partners’ investigation into the nature of the high-rise tower, 200 Greenwich Street takes structural, functional, security, environmental and urban logic to a new dimension. It accommodates the primary vertical circulation, with high-speed shuttle elevators rising to an intermediate sky lobby where the upper floors are served by two further banks of elevators. It also allows for cross-corridor circulation by providing excellent orientation at every level, and opening views out across the office spaces.
175 Greenwich Street/Tower 3
The 71-story 175 Greenwich tower, designed by Rogers Stirk Harbour + Partners, will rise to 1,147 feet above street level with the antennae reaching almost 1,240 feet. It is located on the site bounded by Greenwich Street to the west, Church Street to the east, Dey Street to the north and Cortlandt Street to the south. The tower will include 193,000 square feet of retail (105,000 square feet on three floors at or above street level), 54 office floors (2.1 million square feet) and five trading floors.
According to Rogers Stirk Harbour + Partners, much of the design of 175 Greenwich Street is a function of its position at the center of the various buildings around the WTC Memorial site. As a result, it stands centrally across Greenwich Street from the main axis formed by the two reflecting pools of the Memorial. The design of the tower addresses this central position and accentuates the building verticality relative to the Memorial site. As suggested in the World Trade Center Master Plan, this verticality — relative to the adjacent and smaller building at 150 Greenwich Street — is also accentuated by the stepped profile of 175 Greenwich Street and by the antennae.
The design uses a structural load-sharing system of diamond-shaped bracing which helps to articulate the building’s east-west configuration. All corners of the tower are column free to ensure that occupants of the office levels have unimpeded 360 degree panoramic views of New York.
150 Greenwich/Tower 4
The 64-story 150 Greenwich Street tower, designed by Fumihiko Maki and Maki and Associates, is located on the site bounded by Greenwich Street to the west, Church Street to the east, Cortlandt Street to the north and Liberty Street to the south. The 975-foot tall building will include 56 office floors (1.8 million square feet), as well as five floors of retail, four of which are at or above street level. A third of the office space is slated to be the new headquarters of the Port Authority of New York & New Jersey. The rest will be retained by Silverstein Properties for commercial use, with a potential for 600,000 square feet to be occupied by the City of New York.
According to Maki and Associates, the fundamental approach to 150 Greenwich Street is two-fold: a “minimalist” tower that achieves an abstract sculptural presence, quiet with dignity, on a site directly fronting the Memorial and a “podium” that becomes a catalyst in activating and enlivening the immediate urban environment at pedestrian street level as part of the redevelopment efforts of Downtown New York.
The tower façades are clad in floor to ceiling windows utilizing composite glass with multiple layers of coatings intended to achieve a mat metallic quality with a luminous sheen. It embraces an abstract quality with a unique materiality – minimal, light, cool in color and ephemeral, changing with the light of day. Seen from a distance, the tower presents a unique angular profile that is chiseled at the crown acknowledging the spiral composition formed by the group of four towers, in keeping with the World Trade Center Master Plan.
