We all make mistakes at work from time to time but these mistakes don't normally end up costing
us billions of dollars mistakes on construction mega projects however do from gigantic skyscrapers
shaking and collapsing to scandals and corruption delaying billion dollar projects by decades
building melts cars 20 fence church street is better known as the walkie-talkie it is said
to be one of the ugliest buildings in london but that is the least of its problems the building was
constructed and sold to a hong kong company for 1.8 billion dollars the building was made almost
totally from glass this caused the sun to reflect off it this happens with normal skyscrapers too
but normal skyscrapers have straight walls the walkie-talkies wall however was curved
the concaved curvature meant that the sunlight reflected off the building onto the sidewalk
below it this made the buildings houses and the street below it incredibly hard if you stood
under the building you would experience sun rays reflecting on you six times stronger than normal
the extreme heat caused people to faint and even melted very expensive cars parked on the street
these sidewalks also began to crack from the heat to demonstrate just how ridiculous this was a sky
news reporter fried an egg on the street he was able to fry an egg in seconds using only the heat
reflected from the building the building was designed by architect rafael vinoli
and this is not the first time he's made a building with this same exact design floor
another one of his buildings the vedara hotel in las vegas had this exact same problem
eventually a 14 million sunshade had to be installed on the building so if
you're planning on building a skyscraper in a hot area maybe don't use raphael shaking skyscraper
in may of 2021 the seg plaza in shenzhen china was evacuated that is after the 300 meter high
skyscraper began shaking a video was posted to social media of people running in fear while
the building behind them was shaking wildly terrified bystanders evacuated the building
and ran away afraid it could fall on them at any moment the building is the 18th tallest
tower in shenzhen this only happened a month ago but an investigation has already been launched
a civil engineer said that 70 floors must be examined which will cost millions of dollars
and it will likely cost millions or tens of millions of dollars to fix the problem since
this incident the seg plaza has been closed the shenzhen government said that based on analysis
a seismic event has been ruled out this means it was not an earthquake or anything natural
and instead a fault with the building which has to be fixed miami apartment collapse
this event happened just five days ago dramatic surveillance footage captured a 12-story apartment
complex in miami collapse it's believed that a structural defect was to blame the apartment
complex had been there for 40 years but it only took a matter of seconds for it to completely
collapse the building actually collapsed in three stages at first the center collapsed then the
north face and then the east face some believe that the poolside area may have caved in first
a 2018 inspection highlighted a major error in the original design the engineer frank moribito
warned that the ground floor pool deck was not sloped to drain any water this meant that the
water simply sat there until it evaporated this could have weakened the structure of the entire
building causing it to collapse inside the concrete of the building is reinforced steel
but if water got into the concrete this would rust the steel and corrosion would build up
pressure would then eventually cause cracks in the concrete causing the building to collapse
some now think that the surrounding buildings may also be at risk now this includes champlain towers
north and also 87 park the collapse caused more than 30 million dollars worth of damage and at the
time of recording this the search for survivors is still ongoing city group center the city group
center is a skyscraper in manhattan new york it is 918 feet tall and supported by four foundational
pillars all 111 feet tall but one day a college student realized a major flaw with this building
diane hartley was having a conversation with her professor william le misery she claimed that the
engineers had accounted for the winds that came perpendicular to the building but not the quarter
winds that hit the corners of the building this meant the building could fall over at any moment
engineers carried out tests and found that she was right and that a wind that could knock over the
building would happen once every 16 years if the building fell it would not simply collapse upon
itself instead it would topple over onto other buildings causing a domino effect this would
destroy many buildings in new york and cost many lives at the time hurricane ella was making its
way directly to the city so engineers had to act fast the public was not told because they did not
want to create a mass panic instead at night engineers worked discreetly for three months
eventually they welded lots of steel plates onto the building this increased the city group center
and thankfully hurricane ella did not reach the city the public only found out years later
that was when william lamezarray told the story at a party and someone leaked it to the press
jeddah tower the jeddah tower is a massive billion dollar construction project in jeddah saudi arabia
when completed it will be as big as two empire state buildings it is supposed to be the first one
kilometer high building in the world construction began in 2013 with the project completion date
set for 2018 but in 2021 the building is still incomplete this is mainly because of the 2017-2019
saudi arabian purge this saw hundreds of arrests of prominent saudi arabian princes government
officials and businessmen this was by the country's new leader mohammed bin salman
this caused the jeddah tower to stop being built with only a third completed so far
many investors who had sunk billions into the project were arrested berlin brandenburg airport
this airport is one of the most failed construction projects in the world
the amount of things that have gone wrong is so insane i've made an entire video all about it
construction began in 2006 in berlin germany it was expected to cost 2.4 billion dollars
and be completed in 2011 but so far it's cost around 6 billion and is still incomplete at first
one of the main development companies funding the airport's construction went bankrupt then none of
the fire alarms worked then none of the departure screens worked then 34 miles of the wrong cooling
pipes were installed by the end of the year it's expected this will have cost 8.4 billion dollars
so far and it likely still won't be finished by then in 2020 the airport did partially open
but they now don't have enough money to maintain the airport which will cost an extra 2 billion
dollars so this entire thing may go bankrupt and be shut down shanghai apartment collapse
in 2009 the lotus riverside block 7 collapsed this was a 13-story apartment block located in shanghai
china the building was brand new but the cause of the collapse was because of the construction of
a garage under the building large quantities of earth were removed and dumped in landfill
when it rained this created a muddy foundation for the building which caused it to fall over
it's believed this cost around 80 million dollars now it's time to make your voice
