# The 10 Biggest Construction Fails of 2025 Source: https://www.youtube.com/watch?v=QvHBvm9JIcc Recap page: https://rapidrecap.app/video/QvHBvm9JIcc Generated: 2025-12-31T15:37:18.215+00:00 --- ## Quick Overview The 10 biggest construction disasters of 2025 included a massive 50m deep sinkhole in Bangkok, the scaling back of Norman Foster's iconic stadium design for Manchester United, the halt of almost all NEOM projects in Saudi Arabia due to budget overruns, a tunnel boring machine named Florence getting stuck in Australia's Snowy 2.0 project, a drone attack damaging the Chernobyl reactor shield in Ukraine, ongoing political uncertainty stalling the new Chinese embassy in the UK, the soaring cost of the UK's Hinckley Point C nuclear plant partly due to a costly salmon protection measure, major delays in Germany's Stuttgart 21 rail upgrade, funding freezes impacting California High-Speed Rail and New York's Hudson tunnel gateway program, and the significant downsizing of the UK's HS2 project. **Key Points:** - A massive 50 m deep sinkhole opened in Bangkok in September after work connecting a tunnel to the Vajira Hospital Station ruptured the ceiling, luckily resulting in no casualties. - Manchester United's planned 100,000-seat stadium designed by Norman Foster was confirmed to proceed without the 'big top' umbrella feature just seven months after plans were announced. - Work grew to a halt on almost all of Saudi Arabia's NEOM projects, including The Line, because the development is trillions of dollars over budget, though the Traina ski resort retains backing. - The Snowy 2.0 tunnel boring machine, Florence, got stuck in unexpectedly soft ground, contributing to a cost blowout that doubled the budget to nearly $8 billion US in six months. - The Chernobyl reactor 4 shelter in Ukraine suffered a 6 m wide hole from a February 14th drone attack, igniting the cladding and causing a fire that took weeks to extinguish. - The UK's Hinckley Point C nuclear project is potentially the most expensive in history at 48 billion pounds, exacerbated by a 700 million pound acoustic deterrent planned to save only one salmon every 12 years. - The UK's HS2 project became 335 km shorter and 68 billion pounds more expensive, with a critical 29 km section being de-prioritized for completion. **Context:** The video presents an end-of-year roundup detailing the ten largest and most notable construction failures, setbacks, and disasters that occurred throughout 2025 across the globe. The host acknowledges the hard work of industry professionals but focuses on high-profile projects—ranging from infrastructure and transportation to major architectural endeavors—that experienced significant problems, including structural failures, massive budget overruns, political interference, and engineering mishaps. ## Detailed Analysis The review of 2025's construction fails spanned international projects, starting with a catastrophic sinkhole in Bangkok caused by a tunnel collapse near Vajira Hospital, which required immediate evacuation. In football infrastructure, Norman Foster's ambitious, umbrella-covered stadium design for Manchester United was quietly confirmed to proceed without the signature feature following public criticism. Saudi Arabia's giga-projects, especially The Line, suffered a significant blow as work halted on almost all NEOM developments because they ran trillions of dollars over budget. In Australia, the Snowy 2.0 project faced major setbacks when the TBM Florence became stuck in soft ground, leading to a cost doubling to nearly $8 billion, compounded by later issues with refuge chamber maintenance. Devastatingly, a drone strike hit the Chernobyl reactor 4 shelter in February, blasting a hole and igniting an internal fire. Political wrangling characterized the saga of the new Chinese embassy in the UK, which faced repeated delays due to security concerns and ministerial resignations. In the UK, the Hinckley Point C nuclear plant reached 48 billion pounds in cost, partially due to a controversial 700 million pound measure to protect salmon. German infrastructure saw its railways struggle, with the Stuttgart 21 upgrade delayed past its 2026 opening due to issues with track gradients (1.51% vs. 0.25% allowance) and signaling systems. US rail projects faced funding crises: California High-Speed Rail funding was challenged by a move from President Trump, and the Hudson tunnel gateway program saw $18 billion frozen during a government shutdown; similarly, Britain's HS2 was cut by 335 km and became 68 billion pounds more expensive. ### Bangkok Metro Failure - Sinkhole tore open street in September near Vajira Hospital Station due to tunnel ceiling rupture - 50 m deep sinkhole opened up - No casualties reported and work paused. ### Manchester United Stadium Redesign - Norman Foster's 100,000-seat stadium plan was confirmed to proceed without the 'big top' umbrella feature after seven months of announcement. ### Saudi Arabia's NEOM Halt - Work grew to a halt on almost all NEOM projects, with The Line being trillions of dollars over budget; Traina ski resort remains backed. ### Australian Engineering Setback - Snowy 2.0 TBM, Florence, got stuck in soft ground, causing the budget to double to nearly $8 billion US in six months; later audits ordered. ### Ukraine Chernobyl Damage - A drone attack on February 14th blasted a 6 m wide hole in the reactor 4 shelter, igniting cladding and causing a fire that took weeks to extinguish. ### UK Energy and Rail Woes - Hinckley Point C reached 48 billion pounds due to shortages and a 700 million pound salmon deterrent; HS2 became 335 km shorter and 68 billion pounds more expensive. ### European Rail Troubles - Germany's Stuttgart 21 upgrade is stuck due to track gradients of 1.51% in tunnels and signaling system risks, canceling the 2026 opening. ### US Infrastructure Funding Crisis - California High-Speed Rail faced renewed funding withdrawal attempts by President Trump; New York's Hudson tunnel gateway program had $18 billion in federal funding frozen during a government shutdown.
