FIU Bridge Collapse Due to Negligence, OSHA Claims

Posted on by

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 cracks—work 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.

Oroville Dam Flood Claims Filed

Posted on by

Concrete continues to be placed on the lower chute of the Lake Oroville flood control spillway in Butte County, California. Photo taken Aug. 7, 2017, by Dale Kolke/California Department of Water Resources.

California residents in the path of water spilled from the Oroville dam in February had until Aug. 11, six months after the incident, to file claims.

The Mercury News reported that Butte County farmer George Onyett, manager of J.E.M. Farms and Chandon Ranch, filed a $15 million claim, saying that after the flooding in February, about 25 acres of walnut trees were washed away by the Feather River. He said that 1% to 2% of the trees in his walnut orchard were lost and that his land is now “irrecoverable.”

Because of the near-collapse of the Oroville Dam in northern California, communities as far as 100 miles downstream were at risk of flooding. Problems at the dam began when its main water channel, or sluice, was damaged after a winter season of record rain and snowfall after five years of drought. Torrential rainfall caused water levels to rise so quickly that large amounts of water needed to be released to prevent the dam from rupturing and inundating the communities below.

But when the force of the cascading water created a large crater in the main spillway, use of the emergency spillway was required. This safety backup, however, also nearly failed because the dirt spillway, which had never been fortified by concrete, began to erode, increasing the risk of damage to the dam. In anticipation of a possible disaster, almost 200,000 residents living in the shadow of the dam were temporarily evacuated.

Niall McCarthy, an attorney representing the farm, said the spillway crisis was “entirely avoidable.

” He pointed to waived concerns about inadequacies of the emergency spillway raised by nonprofit groups in 2005, as well as recently released reports by UC Berkeley Professor Robert Bea, of mismanagement by the state Department of Water Resources, according to the Mercury News.

“There was a certainty of failure with respect to the Oroville Dam,” McCarthy said. “The state chose to make band-aid repairs.

The state failed to do its job. (This was) not caused by natural conditions, (but) by human error.”

State officials have maintained it is unclear whether the fluctuation in water releases from Oroville harmed the river and those who farm along it between the shore and major flood protection levees. They argue that some bank erosion would have occurred this year, regardless, given Northern California’s record rainy season, according to the Sacramento Bee.

A number of other business owners and individuals have also filed claims with the state Department of General Services. The Sacramento Bee reported that there were 11 claims at the beginning of July and that there are now a total of 92 claims filed by residents.

A list released by DGS showed claims totaling $1.17 billion. However, that includes a $1 billion claim filed on behalf of “all affected parties” owning land along Northern California rivers where flows were affected by sudden water releases from Oroville. That claim, filed by a Woodland lawyer named James Nolan, added that actual damage amounts aren’t yet available.

Construction efforts at the Oroville Dam spillways are underway and are focused on repairing and reconstructing the gated flood control spillway, also known as the main spillway, by Nov. 1, according to the California Department of Water Resources.

Long-Awaited Infrastructure Repair Bill Nears Passage

Posted on by

Road work

While short-term patches have been used to shore up our nation’s infrastructure for years, leaving large, long-term projects such as bridge repairs to languish, those issues may be remedied by a bill passed by Congress on Tuesday. The measure approves a long-awaited five-year measure of more than $300 billion to fund highways and mass transit. Known as TEA-21, the bill is expected to win final passage by the House and Senate.

“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 ASCE and principal with Hardesty & Hanover LLP, an infrastructure engineering firm, told Risk Management in February 2014. “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.”

In California alone, 58% of roadways require rehabilitation or pavement maintenance, 20% need major maintenance or preventative work and 6% need to be replaced. Traffic volume is also growing 10 times faster than lane miles, the California Transportation Commission reported.

According to the Wall Street Journal, highlights of the bill include:

  • Extending the Highway Trust Fund through Sept. 30, 2020, and allowing for total transportation spending of as much as $305 billion.
  • Renewing the Export-Import Bank through September 2019.
  • Separating the budget for Amtrak’s Northeast Corridor services from the rest of the passenger rail network. This would allow the carrier to invest more in the heavily-traveled lines between Boston and Washington.
  • Preserving a program that allots a share of mass-transit funding for seven high-density Northeast states, including New York and New Jersey. The House had earlier voted to eliminate the set-aside and use the money to fund bus programs whose funding had been slashed in 2012.
  • Providing a total $10.8 billion for freight projects, including establishing a $4.5 billion grant program designed to award money to large-scale freight projects.
  • Providing the largest share of funds to the federal highway-aid program, with authorization to spend $207.4 billion over five years.
  • Providing the next largest share of funding to mass transit projects, at $48.7 billion over five years, an increase over levels approved by the House.

Potholes Cost NYC $27.6 Million in Settlements Per Year

potholes infrastructure municipal risk

Earlier this month, the transportation research group TRIP found that more than 80% of the major roads and highways in the New York City and Newark metropolitan areas were in poor or mediocre condition—the country’s seventh worst ranking among cities with more than 500,000 residents. According to the report “Pothole City: A Data-Driven Look at NYC Roadways,” released yesterday by New York City Comptroller Scott M. Stringer, this crumbling infrastructure has cost the city’s taxpayers over $138 million in the past six years—an average of $27.6 million per year.

The city’s failure to prioritize and effectively manage repairs of potholes on city roads has resulted in 12,268 property damage defective roadway claims and 5,913 personal injury defective roadway claims between fiscal years 2010 and 2015. Of the claims filed, 1,549 property damage claims were settled at a cost of nearly $1.5 million, while 2,681 personal injury claims were settled to the tune of $136.3 million.

The city’s potholes, Stringer said, are a “persistent and pervasive” problem that “deflate tires, break axles and twist ankles, often at a significant financial cost to the city.” His findings are part of an initiative introduced last year called ClaimStat Alert, which aims to identify patterns in claims made against the city in an attempt to reduce the amount paid in settlements, the New York Times reported.

In February 2014, Mayor Bill de Blasio and Department of Transportation Commissioner Polly Trottenberg announced a series of steps to try to improve pothole maintenance, including weekly “pothole blitzes,” citywide targeted repaving, an asphalt engineering technology challenge, and an emphasis on impact prevention. Yet the difficult winter proved quite a challenge.  The average time to close a pothole work order in the first four months of FY 2015 was 6.7 days—nearly triple the 2.4 days during the same period in FY 2014, according to the report. The city stated that, while repair times were “atypically high” through the first quarter of FY 2015, they were “returning to normal levels by October 2014.” Stringer’s report did note, however, “to its credit, the DOT filled over 74,000 potholes (arterials and local streets) in the first four months of FY 2015, a 60% increase over the same period in FY 2014.”

The severe winters felt by the whole Northeast have correlated closely with the number of pothole claims—a predictor many cities may need to weigh more heavily when making weather preparations and budgets.

Snowfall and pothole claims

But patching does not present the best long-term investment of city funds, Stringer said. While the city has initiatives to make patching more efficient, the report said “a more cost-effective, long-term solution may be a complete reconstruction of certain city streets.”

Other financial drains due to road conditions include improperly restored streets and intersections following utility work, milled roadways and hummocks. The comptroller’s office recommended several municipal risk management tactics to tackle these potential claims generators, including:

  • Re-evaluating DOT protocols to ensure that restoration work conducted after street work is properly done. While private companies and utility providers such as Consolidated Edison and Verizon are required by the New York City Administrative Code 18 to maintain the area 12 inches around manholes, vaults and plates flush with the road surface, restoration work following construction sometimes does not match that standard. In addition, the NYPD should also perform spot checks to make sure that contractors performing street work in their precincts have proper permits.
  • Roadways are generally paved in a two-step process. A layer of the old roadway is scrapped off (milling), followed by the introduction of a layer of new asphalt. When the street is milled, it presents a hazard to pedestrians and vehicles using the roadway, and yet there is often a delay in repaving roadway. DOT should examine the extent of these delays and modify its procedures to insure that milled roadways are repaved as soon as possible.
  • Hummocks are variations in road conditions where asphalt is pushed up in a wave-like shape. In many cases, parked buses cause this condition on account of their weight and design. Given the trip hazard posed by hummocks, DOT should work with the MTA and private bus companies to explore the feasibility of using different pavement that is less likely to result in hummock conditions where buses commonly park.
