In the world of construction, the pursuit of architectural wonders often comes with significant risks. YouTube channel MegaBuilds has highlighted some of the most well-known construction mistakes that have led to catastrophic failures and sometimes even tragic loss of life. From leaning towers to collapsing dams, here are nine of the biggest construction blunders the world has ever seen.
1. Lotus Riverside Complex
In June 2009, Shanghai’s Lotus Riverside complex suffered a dramatic collapse when a 13-storey apartment building collapsed and miraculously remained intact. The collapse was caused by excavations for an underground parking garage, which destabilised the building’s foundations. This incident highlighted the dangers of prioritising speed and cost over safety in construction – a common problem in China’s fast-paced construction industry.
2. Intempo skyscraper
The Intempo skyscraper in Benidorm, Spain, became famous due to a rumor that it lacked elevators. While the claim was false, the project was plagued by financial problems, construction delays, and labor issues. Initially started in 2006, the building was finally completed in 2021 after multiple ownership changes and significant investment to resolve its numerous issues.
3. AquaDom
Berlin’s AquaDom, the world’s largest cylindrical aquarium, unexpectedly filled up in December 2022, flooding the lobby of the Radisson Collection Hotel with one million litres of water. The cause was attributed to material fatigue and the large temperature difference between the warm water inside and the cold winter air outside, which caused the acrylic panels to crack.
4. Tower of Pisa
The Leaning Tower of Pisa, an iconic symbol of Italy, owes its famous tilt to a construction flaw. Built on unstable subsoil with a shallow foundation, the tower began to tilt during its construction in the 12th century. Efforts to stabilize it over the centuries have allowed it to remain a historical wonder and a reminder that even mistakes can become beloved monuments.
5. Sampoong Department Store
In 1995, the Sampoong department store in Seoul, South Korea, collapsed, killing 502 people. Originally intended to be an apartment building, the structure was converted to house a large warehouse, putting its integrity at risk. Management ignored cracks that appeared days before the collapse, resulting in one of the deadliest peacetime disasters in history.
6. Hard Rock Hotel Collapse
In 2019, the Hard Rock Hotel in New Orleans collapsed during construction, killing three workers and injuring dozens. Investigations revealed that the support beams were not strong enough due to modifications intended to create higher ceilings. The collapse was a stark reminder of the importance of structural integrity and thorough inspection processes.
7. The sinking of the Vasa
In 1628, the Swedish warship Vasa sank on its maiden voyage, barely leaving port. Designed with an unprecedented second deck of guns, the ship became too heavy and capsized in a gust of wind. This disaster, witnessed by thousands, highlighted the dangers of ambitious engineering without proper testing and balancing.
8. Teton Dam Disaster
In 1976, the Teton Dam in Idaho suffered a catastrophic failure, causing $2 billion in damage and killing 11 people. The earthen dam, built on unstable ground riddled with fissures, ignored multiple warnings from geologists. The disaster underscored the critical need for geological surveys and safety recommendations when building dams.
9. Hyatt Regency walkway collapse
In 1981, the Hyatt Regency Hotel in Kansas City suffered a walkway collapse, killing 114 people and injuring 216. The collapse was due to a design change that doubled the load on a critical set of nuts. This tragedy led to significant changes in construction oversight and is still studied as a cautionary tale in engineering courses around the world.
The consequences of taking shortcuts
These nine construction mistakes, detailed by MegaBuilds, serve as sobering reminders of the consequences of cutting corners, ignoring safety warnings, and failing to thoroughly test and inspect engineering designs. While some of these structures, like the Leaning Tower of Pisa, have become iconic despite their flaws, others are tragic lessons in the importance of diligence and responsibility in construction.
Incorporating lessons from the past
What do you think? What steps can be taken to ensure that safety is not compromised in the pursuit of cost-effectiveness and speed on construction projects? How can the construction industry better incorporate lessons from past mistakes to prevent future catastrophes? How can technological advances be leveraged to improve the safety and reliability of modern construction projects?
