Most Expensive Construction Mistakes in the World
The construction industry is known for its high-risk and high-reward nature. However, the consequences of mistakes made in the construction process can be disastrous and sometimes, very expensive. In this article, we will look at some of the most expensive construction mistakes in the world.
Chernobyl Nuclear Disaster – $235 Billion:
In 1986, a reactor at the Chernobyl nuclear power plant in Ukraine exploded, causing widespread contamination and long-term health effects. The disaster is considered the worst nuclear accident in history and cost an estimated $235 billion in cleanup and compensation.
Deepwater Horizon Oil Spill – $61.6 Billion:
In 2010, an explosion on the Deepwater Horizon oil rig in the Gulf of Mexico caused a massive oil spill that lasted for months. The disaster resulted in 11 deaths and significant environmental damage. The total cost of the spill, including cleanup and compensation, is estimated to be $61.6 billion.
Big Dig Tunnel Collapse – $14.6 Billion:
The Big Dig was a massive infrastructure project in Boston, Massachusetts that aimed to improve the city’s transportation system. In 2006, a section of the tunnel collapsed, killing one person and injuring several others. The total cost of the project, including the collapse and subsequent repairs, was $14.6 billion.
Berlin Brandenburg Airport – $7.6 Billion:
The Berlin Brandenburg Airport in Germany was initially supposed to open in 2011, but it has faced numerous delays and cost overruns. As of 2021, the airport is still not open, and the total cost of the project is estimated to be around $7.6 billion.
Montreal Olympic Stadium – $1.47 Billion:
The Montreal Olympic Stadium in Canada was originally built for the 1976 Summer Olympics. However, the stadium’s retractable roof proved to be problematic, and it was eventually replaced with a fixed roof at a cost of over $1 billion.
Tenerife Airport Disaster – $583 Million:
In 1977, two Boeing 747s collided on the runway at Tenerife Airport in the Canary Islands, resulting in the deaths of 583 people. The accident was caused in part by miscommunication between the pilots and air traffic controllers.
Oslo Plaza Hotel Lean – $135 Million:
In 1989, the newly-built Oslo Plaza Hotel in Norway began to lean to one side. The cause was later found to be a problem with the foundation, and the hotel had to be partially demolished and rebuilt. The total cost of the project was around $135 million.
Sydney Opera House Cost Overrun – $102 Million:
The iconic Sydney Opera House in Australia was originally budgeted to cost around $7 million when construction began in 1959. However, the project ended up costing over $102 million and took 14 years to complete, partly due to design changes and engineering challenges.
Tacoma Narrows Bridge Collapse – $6.4 Million:
The Tacoma Narrows Bridge in Washington state famously collapsed in 1940, just a few months after it opened. The collapse was caused by strong winds that set up a resonant vibration in the bridge’s structure. The total cost of the bridge and subsequent cleanup was around $6.4 million.
Millennium Bridge Wobble – $5 Million:
The Millennium Bridge in London, England was a pedestrian bridge that opened in 2000. However, shortly after it opened, the bridge began to wobble and sway, causing it to be closed for two years while engineers worked to fix the problem. The total cost of the repairs was around $5 million.
