Investigators: Pool Deck Key Focus in Champlain Tower Collapse
Federal investigators say evidence examined thus far indicates the pool deck may have contributed to the Champlain tower collapse.
Federal investigators have been diligently working to uncover the cause of the tragic collapse of the Champlain Towers in Surfside, FL, a disaster that claimed the lives of 98 people in 2021. Two years after the incident, the investigation has honed in on the failure of the building’s pool deck as a key focus.
NIST Says Pool Deck May Have Contributed To Tower Collapse in Surfside
The National Institute of Standards and Technology (NIST), the federal agency leading the investigation, has identified the condo’s concrete columns and pool deck as having been improperly constructed and not meeting building codes. These preliminary findings are the result of thousands of hours of work over the past two years, including interviews with witnesses, examination of design documents, and close scrutiny of sections of steel-reinforced concrete.
Glenn Bell, one of the lead investigators, has emphasized that the evidence examined by the NIST team makes it evident that both the pool deck and the supporting columns of the 12-story condo tower were not adequately built. Bell stated, “The design of the structure at Champlain Towers South failed to meet the codes and standards applicable at the time of original construction and also would not meet current codes and standards.”
Further investigation by the federal team revealed critical issues in the way the concrete itself was cast. Findings show the casting method left it permeable to water, leading to corrosion of the steel reinforcement—a significant compromise to the overall strength of the deck. Additionally, the rebar was improperly placed into the cast concrete slabs of the pool deck, rendering those sections weaker than required. Over the course of the building’s 40 years, heavy items, including large planters containing palm trees, were placed on vulnerable sections of the weakened pool deck, exacerbating its deterioration and stress.
During a recent meeting at NIST headquarters, investigator Jack Moehle presented the team’s leading hypothesis, suggesting that the collapse likely originated from the failure of the pool deck. He highlighted that the deck was lightly reinforced, exhibiting design deficiencies and construction errors. Moehle stated, “It was heavily stressed and showed signs of deterioration. So, it’s highly suspect that failure initiation due to failure of punching could have happened there.” Concrete structural engineers refer to this failure as “punching shear.”
While the NIST team’s final report is not expected for another two years, the recent developments underscore the urgency of reevaluating construction practices and ensuring adherence to building codes and standards. Family members of those who tragically lost their lives and survivors of the collapse reached a $1 billion settlement in the case last year, acknowledging the magnitude of the tragedy and the need for compensation.
Meanwhile, a developer has submitted plans to the town of Surfside for a new 12-story beachfront condo tower on the site where the Champlain Towers once stood. As the investigation unfolds, it is imperative that the lessons learned from this tragedy guide future construction practices and prioritize the safety of structures, including pool decks, to prevent such devastating incidents from occurring again. Pool Magazine will closely follow the progress of the investigation and provide updates to our readers, highlighting the importance of ensuring the highest standards of construction and maintenance within the pool industry.

French Diver Makes Splash After Flop At Opening of Olympic Pool
French Olympic diver, Alexis Jandard, created a memorable moment at the grand opening of Paris’s new Olympic pool, though not quite in the manner he had envisioned.
A startling video captured during the inauguration of the state-of-the-art Paris Aquatics Center on Thursday showcased the 26-year-old Olympian’s unfortunate landing on his right foot while gearing up to dive alongside two fellow athletes. Adorned in a Speedo reflecting the hues of the French flag, Jandard’s discomforting descent saw him landing on his back, ricocheting off the nearly 10-foot-high dive board, and somersaulting into the pool in a rather ungraceful manner.
The incident unfolded in front of a sizable crowd of onlookers, including French President Emmanuel Macron and various dignitaries. Jandard later displayed his scraped back on his Instagram account, maintaining a light-hearted approach to his embarrassing mishap by quipping, “For your information, my back is fine, but my ego…”
Sharing a photo of his reddened back, courtesy of the encounter with the diving board, on Instagram Stories, Jandard assured followers of his well-being. Speaking to RMC Sport, he recounted the unexpected turn of events, stating, “I’m fine. I didn’t hurt myself; unfortunately, these things happen. It happened at a time when I wasn’t expecting it at all.”
Reflecting on the incident, Jandard humorously noted, “I’ve broken boards before, but the board had never broken me before. Now it has.” Despite the hiccup, he maintained an optimistic outlook, remarking, “I would have preferred this ceremony to have gone well from A to Z. There was that little hitch. If it made people smile a little, so much the better.”
Explaining the mishap, Jandard clarified that his leg gave way upon landing but denied any slippage, emphasizing, “It’s a non-slip [board], and what’s more, the board was new, beautiful, and I think there’s still [some of] my back on the board there.”
With a silver and bronze under his belt at the 2022 and 2023 World Aquatics Championships, respectively, Jandard took the incident in stride, admitting, “It’s a shame, but it’s funny. When you take a step back, it’s funny.”
Looking ahead to the 2024 Paris Games this summer, where he is set to compete, Jandard acknowledged the inevitability of such occurrences in his sport, jesting, “These things happen,” while playfully lamenting, “It had to happen in front of the president and the whole of France. I think we chose the right moment.”
Despite being inundated with supportive messages and playful jabs, Jandard maintained a good-natured stance, urging his followers on Instagram, “Enjoy yourselves, make fun of me. I seriously deserve it!”

Earthquake in Taiwan Causes Waterfall From Rooftop Pool
A massive earthquake in Taiwan transforms a rooftop pool into a waterfall. View viral footage.
In a harrowing turn of events, Taiwan was struck by a powerful 7.4 magnitude earthquake, leaving devastation in its wake. The quake, the strongest to hit the island in 25 years, shook the east coast of Taiwan, particularly affecting the city of Hualien and its surrounding areas. With a depth of 34.8 kilometers, the epicenter of the earthquake was located 18 kilometers south of Hualien, according to the US Geological Survey.
As rescue efforts are underway to free those trapped under rubble and debris, the toll of the disaster continues to rise. At least nine individuals have lost their lives, while over 900 others have sustained injuries. The aftermath of the earthquake has left over 100 buildings damaged, with reports of landslides and collapsed structures adding to the chaos.
The force of the quake was so immense that it caused a surreal sight—a rooftop swimming pool overflowing and cascading down the side of a building, creating an impromptu waterfall. Footage captured during the earthquake also shows the sheer force as a man inside a pool struggles to maintain balance, the water swaying violently from side to side.
The region of Hualien County, with a population of approximately 300,000, faces immense challenges in assessing the full extent of the damage. Many inhabitants reside in remote coastal or mountain communities, making it difficult for rescue teams to reach them promptly. The precarious situation is exacerbated by the expectation of aftershocks, with 29 aftershocks greater than a magnitude of 4.0 already recorded near the epicenter.
Compounding the crisis are reports of miners trapped in two mines in Hualien, adding urgency to the rescue operations. Furthermore, over 91,000 households are grappling with power cuts, amplifying the difficulties faced by residents in the aftermath of the disaster.
Despite the widespread destruction, medical facilities in Taiwan’s capital, Taipei City, are functioning, albeit damaged. The Municipal Government has confirmed that hospitals are operating normally, providing critical care to the injured.
The international community has responded swiftly to the catastrophe, with the Biden administration monitoring the situation closely and expressing readiness to offer assistance. In the face of adversity, Taiwan is rallying its resources and resilience, demonstrating solidarity and resolve in confronting this natural disaster.
As the dust settles and the extent of the damage becomes clearer, questions arise about the effectiveness of early warning detection systems in mitigating the impact of natural disasters. Despite Taiwan’s investment in advanced seismic technology, including early warning systems designed to provide crucial seconds of alert before an earthquake strikes, many residents were caught off guard by the sudden and violent tremors. Reports indicate that the early warning detection system, while operational, did not reach a significant portion of the population in time to take preventive action

Patent Pending Apple Watch SOS Feature Could Prevent Drownings
A forthcoming feature potentially destined for the Apple Watch, as detailed in a recent patent application, could serve as a lifesaver for swimmers at risk of drowning.
Outlined in the patent is a capability for the Watch to identify “irregular behavior” and automatically trigger a distress call for assistance.
Apple underscores the alarming statistics surrounding drowning, particularly its prevalence among children, as a leading cause of accidental fatalities.
In the United States alone, drowning claims the lives of over 3,500 individuals annually, ranking as the fifth most common form of accidental death. Tragically, a significant portion of these victims are children.
Emphasizing the critical importance of swift intervention during water emergencies, Apple highlights the dire consequences of prolonged submersion without resuscitation, which can result in brain damage and ultimately, drowning.
A Growing Need For Cost-Effective Wearable Solutions
While acknowledging existing underwater camera systems in some swimming pools aimed at detecting distressed swimmers and alerting lifeguards, Apple notes their costliness and unreliability.
Consequently, there’s a pressing need for a simpler, more cost-effective drowning prevention solution suitable for all types of water bodies, including public and private pools, as well as natural settings like lakes and ponds where installing underwater cameras is impractical.
The patent proposes leveraging wearable devices such as the Apple Watch for broader applicability, increased reliability, and the ability to detect various types of emergencies.
Alerting When Swimmers Are In Distress
For instance, if the Watch detects a wearer who is not proficient in swimming entering deeper water, it can promptly dispatch an alert instead of waiting for signs of distress.
These alerts can be transmitted to nearby devices, including those of friends and family, and seamlessly integrate with existing drowning detection and alarm systems to ensure lifeguards are promptly notified.
Apple Watches already boast capabilities to detect and respond to falls, vehicle accidents, and cardiac irregularities. Heartwarming testimonials featured in Apple’s “Dear Apple” video series show individuals whose lives were saved by these functionalities.
As with many patents from Apple, it’s important to note that not all concepts may materialize into actual products. Nonetheless, this innovation stands as a promising addition for potential integration into future watchOS updates.
