Impaled at WTC: Going forward, whenever people ask me why I’m extremely terrified of heights, I’ll simply show them this article. A 37 year-old construction worker at the site fell about six feet before landing on a two-inch thick piece of rebar, which punctured his left side. The man, whose name has not been released to the public, was rushed to Bellevue Hospital for treatment. Although his injuries are considered serious, he is expected to survive.

The building, which designed by Japanese Fumihiko Maki’s firm as a “respectful and quiet backdrop” to the 9/11 Memorial and Museum, just had its final beam locked down on Monday. According to reports, the interior of the building is expected to be completed by the fall of 2013.

This isn’t the first accident that has plagued the construction site as of late. In February, a large quantity steel suspended by a crane fell roughly 40 stories onto a flatbed truck. Fortunately, no injuries occurred as a result.

4 World Trade Center, which stands at 977 feet tall with 72 stories, is the second building to be completed on the site. In 2006, Seven World Trade Center was the first to be finished, which stands at 50 stories tall.
