Most Expensive Construction Mistakes in the World

Most Expensive Construction Mistakes in the World (Part 3)

6. Liyang Star City

The real estate company determined the delay in construction activity meant that the project could not meet the current market demands. Additionally, the building foundations were exposed to rainwater and were beyond repairs. So, a decision was taken to demolish the buildings using explosives since that would be the most time-efficient method.

15 high-rise houses in Kunming China demolished by blasting in 45 seconds

The blast zone covered approximately 5.38 million square feet (500,000 square meters) area, the largest single-site demolition in China, and about 2,000 households were evacuated after the explosion. 4.6 tons of explosives were placed at 85,000 blasting points in the 15 towers and it took just 45 seconds for the skyrises, except one, to be brought to the ground.

5. The Millennium Tower

301 Mission Street is a high-rise building in the South of Market district of downtown San Francisco. A mixed-use, primarily residential high rise, it is the tallest residential building in San Francisco. The building is being modified in an effort to stop its sinking.

The mission includes two buildings: a 12-story tower located on the northeast of the property, and Millennium Tower, a 58-story, 645-foot-tall (197 m) condominium skyscraper. In total, the project has 419 residential units, with 53 of those units in the smaller tower. The larger tower’s highest level, 58 floors above the ground, is listed as the 60th because floors 13 and 44 are missing for superstitious reasons. Resident services include a private concierge and access to the 20,000-square-foot (1,900 m2) Owner’s Club Level, which features amenities such as a private lounge, wine cellar, and fitness center. The development’s “lifestyle” program organizes cultural events.

4.  Olkiluoto 3 Nuclear Power Plant

The Olkiluoto Nuclear Power Plant, Swedish: is one of Finland’s two nuclear power plants, the other being the two-unit VVER Loviisa Nuclear Power Plant. The plant is owned and operated by Teollisuuden Voima Oyj (TVO), a subsidiary of Pohjolan Voima, and is located on Olkiluoto Island, on the shore of the Gulf of Bothnia, in the municipality of Eurajoki in western Finland, about 20 kilometers from the town of Rauma and about 50 kilometers from the city of Pori.

The Olkiluoto plant consists of two boiling water reactors (BWRs), each producing 890 MW of electricity, together comprising 22% of the country’s electricity generation for 2020. A third reactor, Unit 3, reached the first criticality in late 2021, and at a nameplate capacity of 1,600 MW net electric output, will by itself satisfy 14% of the country’s electricity demand.

 3. Hallandsås Rail Tunnel

The Hallandsås Tunnel is a railway tunnel in Sweden. It connects the northern and the southern sides of the Hallandsås geological formation (a horst). The length is 8.7 km (5.4 mi) (8,722 metres (28,615 ft) in one bore, 8,710 metres (28,576 ft) in the other). It’s utilized by the West Coast Line, on the section between Ängelholm and Halmstad in southwestern Sweden. It has improved the connection between the cities of Gothenburg, Sweden, and Copenhagen, Denmark. In the longer term, it will be a key component in the proposed Oslo to Hamburg high-speed rail link via Gothenburg, Malmö, and Copenhagen.

The project was troubled by construction difficulties caused by groundwater ingress, and a scandal when dangerous sealant materials were used causing workers to become ill and killing local fish and cattle. These caused the project to be halted from late 1997 to 2005 and resulted in large cost overruns. The project was finished in December 2015, over 23 years after the start of construction.

 2. San Francisco-Oakland Bay Bridge

The eastern span replacement of the San Francisco–Oakland Bay Bridge was a construction project to replace a seismically unsound portion of the Bay Bridge with a new self-anchored suspension bridge (SAS) and a pair of viaducts. The bridge is in the U.S. state of California and crosses the San Francisco Bay between Yerba Buena Island and Oakland.

The span replacement took place between 2002 and 2013 and is the most expensive public works project in California history, with a final price tag of $6.5 billion, a 2,500% cost overrun from the original estimate of $250 million. Originally scheduled to open in 2007, several problems delayed the opening until September 2, 2013. With a width of 258.33 ft (78.74 m), comprising 10 general-purpose lanes,[1] it is the world’s widest bridge according to Guinness World Records.

 1. The Harmon Hotel

The Harmon was a high-rise building at the CityCenter development in Paradise, Nevada. The tower was designed by Foster + Partners as a non-gaming boutique hotel and was to be operated by Andrew Sasson’s The Light Group upon completion.

The building featured an elliptical layout and a highly reflective exterior located on the northeast corner of the project at the intersection of Las Vegas Boulevard and Harmon Avenue. Significant construction defects in the building were discovered in 2008, and the project was halted indefinitely. On August 23, 2013, a Clark County court approved the tower’s demolition. The dismantling of the tower began in the summer of 2014 and was completed in the fall of 2015.
