The amorphous plans for the redevelopment of the World Trade Center site were given a reference point on the Fourth of July 2004, 
when the cornerstone of the Freedom Tower was ceremoniously laid. The event was meant to kick off the clamor of construction and 
deconstruction to take place in the months and years ahead. Most of the building in the  immediate future will be focused on the 
substructures of the towers, to be completed by 2009, and the revitalization of the transportation systems converging in Lower Manhattan. 

Construction on the Reflecting Absence memorial begins in 2005, and should be significantly finished by 2009. The Freedom Tower, also 
known as “Tower One” or the “1776 Tower,” is set to be completed in 2007, with all the steel built and retail centers on the bottom floors 
open by 2006. When contacted, the Lower Manhattan Development Corporation could not confirm completion dates for the othertowers, 
since funding and designs continue to be ephemeralcomponents of the process. However, the LMDC is concerned with dedicating maximum 
assistance to redeveloping the site. Deconstruction of the Deutsche Bank building will begin later this year, and will be the future home of 
Tower 5. Calatrava’s beautiful permanent WTC PATH terminal will open in 2006. The new Fulton Street Transit Center by Grimshaw, linking 
MTA Subway, PATH, and pedestrian tunnels downtown, will open in 2007. Construction of Fulton and Greenwich Streets through the WTC
site is slated for completion by 2009, though the LMDC would not commit to those plans. The rebuilding of West Street along the eastern 
slurry wall of the World Trade Center site is equally uncertain. 

Lower Manhattan will soon be a bustling transportation hub, but a web of new construction until at least 2015. Please check back here 
for updates on the redevelopmet timeline.

Silverstein Properties

What is being built? ~ In July of 2001, Larry Silverstein, a very prominent developer of New York real estate, leased the World Trade 
Center complex from the Port Authority of NY and NJ. Specifically, 7 WTC, the only WTC Tower that is completely built and operating, is 
a glass office tower that creates “openness” in space and helps to create more interaction between co-workers. Towers 2, 3, and 4 will 
spiral in rising heights with each other from 974 sq. ft. to 1,200 sq.ft., which will equal 200 stories.


Timeline/History of the Project:
~ 1970’s – Port Authority owned the WTC complex
~1980 – Silverstein developed a plot of land across the street from the North Tower and built a 1.9 million sq, ft. skyscraper, which was 
the original 7 World Trade Center.
~1990’s – WTC became prime property; Governor Pataki and then-Mayor Giuliani spurred commercial revival in Manhattan.
~July 2001 – Silverstein Properties signed a 99-year lease for WTC complex.
~September 11, 2001 – Terrorist attacks destroy WTC complex.
~ Silverstein’s WTC Towers (2, 3, and 4) will be built and completed in 5 years by the architectural firms of Foster and Partner and
Adamson Associates (the Freedom Tower and new transportation terminal will be under the control of the Port Authority). 
~ The Port Authority also has control over the building of Tower 5. The architectural plan for WTC 5 has yet to be determined, but it will 
be built on the formerDeutsche Bank property at 130 Liberty Street. The deconstruction work of the Bank has been taken over by the 
Lower Manhattan Development Corporation (LMDC) and is scheduled to be completed in September 2007. 
~ 4 phases: 1st phase is to reinforce slurry walls, engineering and surveying work will take place, materials will be delivered and the original 
box beams of the Twin Towers must be protected; 2nd phase – ended March 31, 2007; 3rd phase – design development ends July 1, 2007; 
4th phase – actual groundbreaking and the start of construction of Towers 2 and 3 by 2008. 
                         
~ Projected Completion of the WTC Towers: 
     Freedom Tower (WTC Tower 1) – 2011 completion by David M. Childs (Skidmore, Owens and Merrill); 
     200 Greenwich (WTC Tower 2) – 2012 completion by Norman Foster (Foster & Partners); 
     175 Greenwich (WTC Tower 3) – 2011 completion by Richard Rogers (Richard Rogers Partnership); 
     150 Greenwich (WTC Tower 4) – 2011 completion by Fumihiko Maki (Maki & Associates).

Completions and Milestones ~
~ 7 WTC is already 2/3 or 1.1 million sq. ft. of it is leased/ 70% occupied and Silverstein is expecting to lease the rest of the floors 
by the end of 2007. 
~ February 18, 2008: Port Authority completes excavation for Towers 3 and 4.
~ The Freedom Tower (1 WTC) is have steel been raised almost to street level and the building's foundations and footing are almost 
complete.

Funding ~
Court decisions require insurers to pay Silverstein and the Port Authority $4.6 billion towards the construction of the WTC buildings. 

News ~
 7 WTC is the first NYC office tower to receive a gold rating for environmental stability from the U.S. Green Building Council. In fact, WTC 7 
is the first “green building” in New York City. 

Significant Aspects of Buildings ~ 
Silverstein Properties, Inc. development has chosen to make the Towers “green buildings,” in which the structures are made healthier 
for occupants. These buildings help to conserve energy, water and raw materials; improves air quality; reduces solid waste; and it cost 
less to build and operate.
