FIU Bridge Collapse Due to Negligence, OSHA Claims

According to a new Occupational Safety and Health Administration (OSHA) report, negligence from almost every party involved led to last year’s collapse of a pedestrian bridge at Miami’s Florida International University, killing 6 and permanently disabling one other. The pedestrian bridge project was supposed to pose lower risk of disruption thanks to a construction method called “accelerated bridge construction,” intended to minimize the time and risk involved on-site by performing much of the work off-site and then relocating it. Yet, according to the report, almost all parties involved shared some fault for the collapse, most notably FIGG Engineering-Bridge Group, the firm that designed the bridge.

On March 15, 2018, the bridge collapsed onto the street below, where multiple cars were waiting at a stoplight. FIGG Engineering-Bridge Group had designed the bridge and engineering firms Louis Berger and Bolton Perez and Associates provided additional design checks. Miami-based construction firm Munilla Construction Management (MCM) managed the bridge’s construction off-site and relocated it to the school using the accelerated bridge construction method.

OSHA says that FIGG produced a “deficient” design and the company’s attempts to seal cracks in the bridge led to its collapse.

FIGG reportedly also ignored MCM workers’ concerns about the bridge’s growing cracks, saying that it had examined them and did not find anything troubling. Given this response from FIGG, OSHA wrote that MCM should have exercised “independent judgment with regard to implementing necessary safety measures” to address those growing cracks and close the street below. OSHA also said that the road should have been closed immediately as FIGG attempted to repair the crackswork that, as the Miami Herald reported, put additional stress on already-faulty and weak internal support cables.

According to the OSHA report, at a meeting with all construction participants on the day of the collapse, FIGG’s lead engineer “acknowledged that his computations could not replicate the cracks and, therefore, he did not know why the cracks were occurring.” Upon being told that the cracks were widening daily, he “stated more than once that the cracks did not present any safety concerns.

” The engineer had also reportedly called the Florida Department of Transportation (FDOT) three days before the collapse to claim the same.

The report also calls into question Louis Berger’s independent review of the bridge’s designs, noting that the firm’s “constrained” budget and time led to deficiencies in the firm’s analysis, including not examining the post-installation construction phase, during which the collapse happened. OSHA said FIGG violated FDOT requirements by not requiring Louis Berger to conduct the full examination and failing to provide the firm with necessary documents.

Bolton Perez and Associates was reportedly aware of the cracks in the bridge, but failed to follow DOT requirements to “exercise its own independent professional judgment,” and did not recommend that the street be closed.

After the incident, victims filed 18 lawsuits against 25 companies connected with the collapse, with depositions beginning in May 2019. According to the Miami Herald, MCM declared bankruptcy and in May, the judge overseeing its bankruptcy approved a $42 million insurance settlement for victims and their families. Additionally, FIU has designated that its $5 million insurance payment should go to the victims. FIGG released a statement this week calling the OSHA report “factually inaccurate and incomplete,” citing “flawed analysis.” A National Transportation Safety Board report is forthcoming, but may not be released until 2020.

Are Critical Infrastructure Issues Finally Being Addressed?

The recent collapse of an Interstate 75 overpass in Cincinnati, killing a worker and injuring a truck driver, is yet another reminder of the plight of America’s infrastructure, which is estimated to require billions of dollars to bring up to 2015 standards.

The bridge that collapsed had been replaced and was being torn down as part of an extended project to increase capacity on a congested, accident-prone section of the interstate, according to the Associated Press.

President Obama, speaking today in Saint Paul, Minnesota, outlined several proposals, including launching a competition for $600 million in competitive transportation funding and investing in America’s infrastructure with a $302 billion, four-year surface transportation reauthorization proposal, according to a press release from the White House. Obama also plans to “put more Americans back to work repairing and modernizing our roads, bridges, railways, and transit systems, and will also work with Congress to act to ensure critical transportation programs continue to be funded and do not expire later this year.”

More and more, states are finding ways to fund infrastructure repair. New York Gov. Andrew Cuomo, for example, in his State of the State address, proposed $3 billion in loans and grants for infrastructure upgrades, including $1.3 billion for the Thruway and the new Tappan Zee Bridge, which is under construction. The money, he said, would come from a a $5.4 billion windfall from bank settlements.

A report by the American Society of Civil Engineers (ASCE), “Failure to Act: The Impact of Current Infrastructure Investment on American’s Economic Future,” found that the cascading impact of putting off repairs affects the entire economy. The report concluded that, between 2013 and 2020, there will be an investment gap of about $846 billion in surface transportation.

At risk are a number of bridges and overpasses. According to Risk Management magazine:

“Right now, 11% of our bridges across the country are rated structurally deficient and another 13% are considered functionally obsolete,” Andrew W. Herrmann, 2012 president of the American Society of Civil Engineers (ASCE) and principal with Hardesty & Hanover LLP, an infrastructure engineering firm. “This means they were designed to an older standard, so they may not have the same lane widths or turning radius or may have been designed to carry lesser loads.”

Deterioration of the nation’s infrastructure jeopardizes public safety, threatens quality of life, and drains the U.S. economy. “If they have to start closing down, restricting or putting mileage postings on bridges, the economy will be affected,” said Herrmann, who served on the advisory council for the 2003, 2005 and 2013 report cards and chaired the council for the 2009 edition.

“Bridges are the most pressing need in the infrastructure overall. You can have all the roads and highways you want, but if you don’t have the bridges to cross the rivers and intersections, it slows everything down.”

He observed that, from a bridge engineer’s perspective, investments need to be made to keep bridges in good repair. The Federal Highway Administration (FHWA) estimates that it needs $20.5 billion annually to eliminate the nation’s backlog of bridge repairs by 2028, but only $12.8 billion has been budgeted. The challenge, then, for federal, state and local governments is to increase investments in bridges by $8 billion annually.
