The FIU bridge, meant to cross eight lanes of traffic at a particularly dangerous intersection in front of the school, was designed to double as an amenity deck and would have featured a bike lane for students. Instead of being constructed in situ, the span that collapsed was built on temporary supports on the side of the road, and rotated 90 degrees into position on March 10th. Using this “Accelerated Bridge Construction (ABC) method” to build the bridge’s superstructure elsewhere was touted as a way to cut costs and minimize disruptions to traffic below. According to a press release from LIU, the bridge would have also been the first in the world to have been constructed from self-cleaning concrete. It’s currently unclear whether the construction methods used to build the span played a part in the collapse, which flattened the cars underneath at the time. Miami-Dade Mayor Carlos Gimenez had said earlier that day that the bridge had just successfully completed stress testing. In a statement given to the Miami Herald, FIU President Mark Rosenberg said that the testing was done in accordance with best practices. “I know that tests occurred today. And I know, I believe, that they did not prove to lead anyone to the conclusion that we would have this kind of a result. But I do not know that as a fact.” Florida Senator Marco Rubio took to Twitter to discuss the work being done on the bridge before its collapse, saying “The cables that suspend the Miami bridge had loosened & the engineering firm ordered that they be tightened. They were being tightened when it collapsed today”. The engineering firm Rubio is referring to is FIGG Bridge Design, who were collaborating with Munilla to build the bridge. While the span was to be supported by steel suspension cables installed from a central column later on, Rubio may have been referring to tension cables inside of the bridge itself. It's unclear what form of temporary support was holding up the bridge at the time of the accident. At the time of writing, it’s unclear why engineers had chosen to stress test the bridge while allowing traffic to pass underneath, or if the cable tightening had played a role in the failure. The $14.2 million bridge, financed through a US Department of Transportation TIGER grant, had originally been slated to open in early 2019.

"We are all here today for the exact same reason that many similar Congressional committees and subcommittees have been convened in the aftermath of virtually every major disaster over the past several decades—the system is broken, everyone is mad, and billions of dollars continue to be wasted. The Post-Katrina Reform Act reformed next to nothing; the Hurricane Sandy Recovery Improvement Act improved far too little. Now let’s try something different. Let’s start over, decide who and how much we want to help, establish a comprehensive policy for disaster resilience and recovery, devise an implementation strategy, build an integrated set of programs that get the job done, and empower our public servants to lead genuine, sustainable, cost effective efforts that restore communities and support families in times of need."
Firetrucks, police cars, and a helicopter surrounded 1 World Trade Center this afternoon to save two window washers who became trapped near the 69th floor on the south side of the building. According to the New York Times, the machine controlling the scaffolding, to which the washers were strapped, malfunctioned. Firefighters were able to reach them by cutting a hole in a nearby window and then bringing them to safety. An official from the fire department said he believed the cause of the scaffolding failure was a snapped cable.
“They are in a difficult spot,” a fire department spokesman told the Wall Street Journal. “They are feeling the effects of hanging in there.”
"I was surprised that throwing away the title of 'architect' was so welcomed by people" #toyoito #homeforall — Chris Bentley (@Cementley) October 15, 2013Ito said he’s often asked how to bridge the gap between this post-disaster work and his typical practice. His reply: “Build architecture that is open to nature and harmonizes with people.” Ito’s visit also included a tour of “News from Nowhere,” the first U.S. presentation of the work by Korean artists Moon Kyungwon and Jeon Joonho. Moon and Jeon meditate on a post-apocalyptic society composed of nation-corporations that control the technology necessary to sustain life after a 22nd century global catastrophe. That equipment is displayed throughout, along with a pair of lyrical videos that sketch the story of two survivors. The exhibition also features elements of Ito’s “Home-for-All” project alongside work from fashion designers Kuho Jung and Kosuke Tsumura; mime Yu Jin Gyu; and design firms MVRDV and takram design engineering. The exhibit is on display at the Sullivan Galleries — 33 S. State St., 7th floor — through December 21.
