Steel starts on site at Ground Zero memorial

Steel installations for the 9/11 memorial and museum started this week at the World Trade Center, where construction began two years ago.

Structural steel erection is beginning in the northeast corner of the North Tower footprint, where the north pool of the Memorial fountains will be, and will move westward over the next year, bringing the Memorial & Museum construction to street level.

The National September 11 Memorial & Museum is being built in memory of the nearly 3,000 people who died in the terrorist attacks of 11th September 2001 and 26th February 1993.

Construction workers have erected the first 7.5m long structural steel column, weighing 3,500 kg. A total of 9,250 tonnes of structural steel will be installed for the memorial project.

National September 11 Memorial & Museum President Joseph Daniels said, "Last year, I saw these steel beams being fabricated in a plant in South Carolina. Seeing this steel installed on the site reminds me of the scores of dedicated workers involved in making this Memorial a reality.

"Working with the Port, we are moving forward aggressively with construction. While there is a lot of construction work ahead of us, we have an opportunity to see this Memorial open in time for the 10th anniversary of the attacks."

Construction on the footings and foundations of the Memorial were completed last month. Work is also under way to build a new concrete slurry wall behind a section of the existing wall, allowing this piece of the original site to be displayed in the museum.

The eight-acre Memorial & Museum complex will include a landscaped Memorial Plaza with nearly 400 trees at street level. They will surround two massive pools set within the original footprints of the Twin Towers, with 30-foot waterfalls cascading down their sides.

Names of the victims of the 2001 and 1993 attacks will be inscribed around the Memorial pools. Visitors will enter the Memorial Museum through an aboveground Museum Pavilion that sits between the two pools.

Port Authority Chairman Anthony R. Coscia said, "The Port Authority is proud of its role in building this project of national significance. The beginning of the steel installation marks an important milestone in the Memorial’s construction, and we will continue to work aggressively to build a Memorial that honors the lives of those lost on 9/11."
