The 10 Biggest Construction Fails of 2025

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.
