skyscrapers in a spiral structure to be built by Silverstein Properties
at the World Trade Center site, according to Janno Lieber, president of World Trade Center Properties, an affiliate of Silverstein Properties.

“This is an exciting moment in this project,” Lieber said Wednesday at
a Bisnow-sponsored conference
addressing the state of the construction industry. “We now have the
entire WTC site under development, with 7.5 million square feet of
space from Towers 2, 3 and 4.”

First up in what is expected to be a four-year project
at Tower 3 is the mobilization stage, a precursor to the excavation
period, when the foundation contractor, the Laquila Group, will start
drilling through the rock to create the tower’s footing, said Dara
McQuillan, Silverstein’s senior vice president of marketing and
communications, in a follow-up interview. Once the excavation is
complete, the Laquila Group will be able to start pouring the concrete
footing, he said.

It is unclear how long the first phase of construction will
last, but the entire Tower 3 project, located at 175 Greenwich Street,
is slated for completion in December 2014, McQuillan said. Tower 4,
Lieber noted at the conference, is scheduled to open in 2013.

With 54 office floors, Tower 3 includes 2.5 million square
feet of office space and five trading floors. The site will have three
retail floors from the ground floor to the third floor plus two below
grade. The tower, designed by Rogers Stirk Harbour + Partners, will
have a reinforced concrete core and columns with steel girders and
beams. Bound by Greenwich Street to the right, Church Street to the
east, Dey Street to the north and
Cortlandt Street to the south, Tower 3 is at the center of the WTC
memorial site development. The complex — with an estimated price tag
of close to $1 billion — includes four new skyscrapers on Greenwich
Street plus a fifth on Liberty Street, a Sept. 11 memorial and museum,
a WTC transportation hub, a retail complex and a performing arts

The entrance to the three-level public lobby of Tower 3 is on Greenwich Street, with views of the entire WTC memorial project.
