In the realm of construction, there’s no room for mistakes. The safety of people and the stability of their livelihoods are on the line. A single overlooked error, be it due to human fault, negligence, or unforeseen environmental factors, can result in devastation. Tragically, lives are often lost, regardless of the cause. What stings the most is the fact that many of these disasters could have been avoided.
From collapsing buildings to bridges falling apart, whether caused by faulty construction practices, substandard materials, lax safety regulations, or the relentless forces of nature, each tragedy offers a crucial lesson. Here are ten of the most devastating incidents linked to construction errors.
10. Pleasants Power Station
In early 1978, construction began on a second cooling tower for Pleasants Power Station in West Virginia. On April 27, most of the workers were on scaffolding inside the hyperbolic-shaped structure when the concrete on the 28th lift began to peel away (from the previous day's pour). The scaffolding collapsed, causing all of the workers to fall to their deaths, with some being trapped under the debris. Tragically, fifty-one workers lost their lives. This incident came to be known as the Willow Island disaster.
Witnesses described the sound as resembling a train derailing. The only survivors were seven workers who were performing tasks at ground level. In the aftermath, it was suspected that the scaffolding's concrete had not fully cured, contributing to the disaster. At the time, the cause of the collapse remained unclear, as the 50-meter (165 ft) tower had been constructed in a manner similar to other towers. However, authorities expressed doubts about the strength of the concrete used. One rescue worker recalled that the concrete 'crumbled in his hands.' David H. Rhone, head of the Occupational Safety and Health Administration (OSHA) investigation, speculated that the collapse might have been caused by a combination of stress, mechanical failure, and the concrete's insufficient strength.
9. Deadly Tower Crane Collapse
On March 15, 2008, a tower crane approximately 76 meters (250 ft) tall collapsed during the construction of a 43-story concrete-framed condominium at 303 East 51st Street in Manhattan. Six construction workers were killed, along with a civilian who lived in a nearby apartment, when part of the crane crashed into the building. The workers were placing lateral tie beams on the 18th floor to support the crane. About an hour before the collapse, the crane had been 'jumped,' meaning four additional sections were added to the lower mast.
The construction team was installing the tie beams for the first time without the aid of a mobile crane. The 19th floor had already been poured, and preparations for the 20th floor were underway. Further investigations revealed that using polyester slings was a questionable choice, the collar was improperly rigged, and the slings were not protected from sharp edges. Additionally, a deteriorated sling, which should have been discarded, was used instead.
8. Hawk’s Nest Tunnel Disaster
One of the deadliest and most unorthodox construction disasters occurred in the early 1930s during the construction of a 5-kilometer (3 mi) tunnel through Gauley Mountain, between Ansted and Gauley Bridge in West Virginia. This tunnel was intended to divert water from the New River to a hydroelectric power plant downstream. Hundreds of unemployed workers, two-thirds of whom were African American, were brought in for the project. After drilling about 10 meters (33 ft) into the mountain, they encountered rock containing high levels of silica. Due to dry-drilling, this created large amounts of dust in the air, making working conditions in the tunnel extremely hazardous.
As the Hawk’s Nest Tunnel was licensed as a civil engineering project, the basic safety protocols were not enforced. Workers were placed in confined spaces with limited access to breathing protection and no dust control. Over the course of several months, workers began showing signs of silicosis, though they were diagnosed with a new condition called “tunnelitis.” Of the approximately 5,000 workers involved, more than 2,900 worked inside the tunnel. At least 764 of them died from silicosis, a disease caused by inhaling silica dust, which ultimately led to their death.
7. Deepwater Horizon Oil Rig Explosion
In 2010, one of the most devastating marine oil spills occurred in the Gulf of Mexico, on the Deepwater Horizon, a BP-operated oil rig located at the Macondo Oil Prospect near the Mississippi River Delta in the United States. One fateful night, a surge of natural gas broke through a concrete core intended to seal the well for future use. The gas traveled up to the platform, where it ignited. Eleven workers lost their lives, and 17 were injured before the rig capsized and sank. A similar disaster had occurred on another BP-owned rig in the Caspian Sea. It was suspected that the concrete cores used were too weak to withstand the pressure due to the inclusion of nitrogen gas in the mixture to speed up curing.
The rig’s blowout preventer (BOP), a fail-safe system designed to close the channel through which oil was being extracted, failed to function properly. According to estimates from U.S. government officials, at the height of the spill, more than 60,000 barrels of oil were spilling into the ocean every day. Despite numerous clean-up efforts, the damage had already been done. The spill caused significant harm to surrounding industries, leaving as many as 12,000 people temporarily unemployed. It also devastated the wildlife in and around the Gulf of Mexico, resulting in the deaths of over 800,000 birds and 65,000 turtles. Additionally, it is believed that around 20 percent of the oil sank to the ocean floor, severely damaging deep-sea ecosystems.
6. Mecca Crane Collapse
In Saudi Arabia, a massive red and white crane collapsed into the Grand Mosque in Mecca, the largest mosque in the world, during a time when it was packed with worshipers. This tragic incident occurred on September 11, 2015, resulting in the deaths of 111 people. Nearly 400 others sustained nonfatal injuries. Graphic images and videos of the aftermath spread quickly across social media.
The head of Saudi Arabia's Civil Defense determined that the crash was caused by strong winds and heavy rain. Just before the incident, the city experienced an unusually large amount of rainfall, accompanied by winds of up to 80 kilometers per hour (50 mph). In response, further investigations were launched to reevaluate the safety protocols at the construction site.
5. The Savar Building Collapse
The Rana Plaza, a five-story commercial building in the Dhaka District of Bangladesh, collapsed on April 24, 2013, during the morning rush hour, claiming the lives of 1,134 people. Rescue operations continued until May 13, saving approximately 2,500 people from the debris.
An extensive investigation revealed that the mayor and building owners unlawfully approved permits for the addition of extra floors. During construction, substandard materials were used, and safety regulations were disregarded. To maintain factory operations during power outages, large generators were installed on the upper floors, putting additional strain on already unstable upper levels. Reports indicated that the building shook whenever the generators were running.
On the day before the disaster, cracks appeared in the foundations and walls of the building. An engineer was called to inspect the structure and deemed it unsafe. Despite this warning, the owners insisted that construction continue, and the following day, the tragedy occurred.
4. Rio De Janeiro Building Collapse
On January 25, 2012, three buildings near the Municipal Theatre and the headquarters of oil giant Petrobras in Rio de Janeiro collapsed, resulting in 17 fatalities. Emergency responders quickly arrived, but it soon became apparent that finding survivors beneath the rubble was unlikely. Many residents witnessed the destruction of their homes and livelihoods. A building inspector from Rio de Janeiro’s Regional Council of Engineering expressed concerns that illegal construction projects might have been taking place in one of the buildings, possibly contributing to the disaster.
A witness to the collapse stated that he wasn't surprised by the buildings’ fall, noting that the area’s infrastructure was largely unregulated and ignored by safety authorities. Professor Paulo Roberto do Lago Helene, from the University of Sao Paulo’s civil engineering school, remarked that Brazil still lacked laws requiring building owners to regularly assess the condition of their structures at the time.
3. Florida International University Pedestrian Bridge Collapse
On March 15, 2018, a newly constructed pedestrian bridge at Florida International University, designed to connect the campus with off-campus housing, collapsed onto Southwest Eighth Street. Six people were killed, and several others were injured. The $14.2 million bridge had been intended to open in 2019 but was installed earlier than planned, following a risky installation method that involved placing the walkway before the main support tower. This premature approach led to the collapse.
At the time of the collapse, two workers were on the bridge, conducting a stress test and tightening the steel cables running through the bridge's slab sections. Experts later suggested that the cables might have been overtightened, causing the structure to 'camber,' or bend, similar to what witnesses reported seeing before the tragedy. In addition to the bridge’s unusual weight, an engineer had left a note warning of cracks at one end of the bridge two days prior. Unfortunately, the message came too late, and no evidence was found at the time to indicate that the cracks were a factor in the collapse.
2. Kolkata Bridge Collapse
In Kolkata, India, a bridge collapse resulted in three fatalities and 25 injuries. The Majerhat bridge in South Kolkata gave way at approximately 4:40 PM on September 4, 2018, sending ten vehicles tumbling into the rubble below. Construction workers from a nearby site assisted in rescuing at least five individuals.
Mamata Banerjee, the Chief Minister of West Bengal, raised concerns regarding the maintenance of the 40-year-old bridge. This was not the first deadly bridge incident in the region, as another bridge under construction in Kolkata's Burrabazar area had collapsed in 2016, killing 26 and injuring 90 people. In that case, eight engineers were arrested for negligence. The state's governor, Keshari Nath Tripathi, criticized the lack of proper maintenance on the Majerhat bridge, mentioning that a pit had been present on the bridge for an extended period, though it was unclear whether it had been reported by the public works department.
1. Apartment Building in China Collapses
On June 27, 2009, a nearly finished 13-story apartment building in Shanghai, China, unexpectedly collapsed, raising concerns about building safety. The structure was part of the Lotus Riverside apartment complex, and tragically, one worker lost his life. Nine employees of the development company were taken into police custody for questioning. Initially, doubts about the building's quality were set aside, as it fell in one piece, leading some to believe that poor construction was not the cause.
The sight of the collapsed building quickly turned into a tourist attraction. Further investigations revealed that the license for the company behind the development, Shanghai Meidu Real Estate Co., had expired in 2004. During the investigation, their funds were frozen. A former construction technician stated that corruption within China's building industry was widespread, with developers bribing officials to obtain the necessary permits to begin construction.
