20 Years Later - Rebuilding the World Trade Center Site

September 11, 2021

20 years ago, a devastating event shook the world and no one will ever forget.

We remember each person lost.

We remember, recognize, and appreciate the countless amount of work that went into search and rescue, securing the surrounding area, and securing our nation.

We reflect on the revitalization of lower Manhattan and the reconstruction of the World Trade Center that continues today.

We invite you to remember some of the memories that have shaped life for all of us.


September 21, 2001  Members of the Vidaris team, then known as Israel Berger and Associates, arrived on the scene days after the attack to provide emergency response and repairs on buildings surrounding the World Trade Center site. Vidaris was involved in more than a dozen projects in the surrounding area and is still working on some of the sites daily. 







2001  Within days, the team was approached by Silverstein Properties to assist in insurance related matters on World Trade Center Tower 7 and then worked on the redesign and construction of the first building to be reconstructed on the site. Pictured above is Tower 7 in 2013.



2007  The team was then contracted for the Freedom Tower, now known as One World Trade Center. The photo above shows the first steel beam of One World Trade Center rising, and the photo below shows the overall construction site with the starting-to-rise One World Trade Center.





2007  The design team held countless meetings.  Pictured above is Marc Weissbach at Silverstein's office.

Vidaris has invested more than 30,000 hours since 9/11 on the reconstruction of One World Trade Center alone. Vidaris has provided building envelope consulting, roofing & waterproofing, LEED/green and energy consulting and monitoring services across the various World Trade Center and adjacent sites. 


2008 Vidaris facilitated curtain wall mock-up testing on One World Trade Center.

"We are humbled and honored to have been and continue to be involved in the reconstruction of the World Trade Center Site," said Marc Weissbach.

Lindsey Snogles, seen below with the spire for One World Trade Center, spent years in fabrication plants and on-site monitoring and assisting through project completion.  Lindsey also spent thousands of hours toward sourcing the marble for One World Trade Center's Lobby.



Edward Madocks, (former) Director of Roofing and Waterproofing at Vidaris, shares how much he remembers working outside in the brutal cold of winter, and how despite dealing with weather conditions, "it was such a privilege to work on and be responsible for one of the most iconic buildings of my lifetime...and in history."
