12 Engineering Mistakes That Turned Out Not to Be Fails

not every finished product resembles the blueprint it was based on sometimes mistakes are made sometimes plans have to be changed often an engineer will finish creating something only to realize that there's a big problem with their design one that they never thought of before they started building sometimes a mistake like this will doom a construction project completely but other times they'll turn out to be happy little accidents like all the incredible engineering calculations you're about to see in this video land space comes at a premium in New Zealand it's one of the world's smaller countries and building large scale transport facilities isn't easy especially when one hand doesn't know what the other one is doing we think that's how Gisborne Airport in New Zealand's Elgon suburb managed to end up being built with a railway line running straight through the middle of it the trains run right across the airport's main runway which sounds like a recipe for disaster but despite the fact that the two different types of vehicle frequently cross close enough to each other to make you wince there's never been a major accident here it helps that the only planes that fly from here are small white ones used for internal flights or flights to Australia as opposed to heading out elsewhere in the world we can't even imagine how terrifying it must be to be sat in the carriage of a train and see a plane driving directly towards you at top speed but so far the planes have all taken to the air before plowing directly into the side of the rail cars let's hope things stay that way there are some incredible and unique buildings and England's capital city of London architects with a flair for the unique are often sought out and paid millions of dollars to bring their best work to the area and create something that will stand out from the crowded skyline one such innovation was a building that's been nicknamed the walkie talkie because of its distinctive shape unfortunately for the skyscraper which is situated on Fenchurch Street was voted the worst building in the United Kingdom in 2015 the shape and design of the building led to some unforeseen ball accidents the glass frontage of the structure reflects the Sun with such intensity on summer days that it set a carpet on a neighboring building on fire in 2013 and followed up that trick by melting the roof of a luxury car parked on the street below it during high winds the curved exterior of the tower creates a wind tunnel strong enough to knock pedestrians over despite all of that it's still standing and Londoners have grown to love it Australia's Sydney Opera House isn't just one of the most iconic buildings in Australia it's one of the most iconic buildings in the whole world everyone knows it and most people love its iconic design so it might surprise you to hear that it's considered to be a classic example of bad project management when the foundations were laid in 1959 it was supposed to be finished within four years and cost around seven million Australian dollars it actually took 14 years to build and by the time it was ready to open more than 100 million Australian dollars had been spent on it talk about running over budget the problems began when the government ordered construction work on the outer shells of the building to begin before architect jørn Utzon had finalized the design meaning the Danish designer had to provide updated plans to builders as they were in the middle of the building process unsurprisingly this led to mistakes being made by the mid-1960s with construction delayed by disagreements and impracticality 'he's a frustrated it's on resigned from the project taking his designs with him that meant new architects had to come in and finish the building without being able to see boots ons blueprint it's a miracle that was ever built at all all rail crossings are dangerous no matter how many barriers or flashing lights you put up there's always the occasional driver who presumes that they're indestructible and will try to cross the railway in front of an approaching train imagine how much more dangerous such a crossing would be if there were no barriers or lights it's unthinkable anyone would ever create such a thing and yet they have in Baku the capital city of Azerbaijan as we can see in this shocking footage full sized trains emerge without warning from the side of this busy highway and very nearly collided with cars in the process of doing so the footage prompted shock all around the world when it went viral in 2016 prompting the authorities in Baku to think about their transport logistics again and remove the railroad the area is safer now but it's beyond belief that anyone ever thought that this was okay if you visit Mike long in Thailand you'll find a busy bustling street market waiting for your patronage you'll also find a busy Tyrael weight line mystifying Li they're both in the exact same place six trains run directly through the middle of the market every day the street vendors have to scramble to get out of their way when they approach fortunately they've got this down to a fine art they know what time the trains are due to come through their street and so they get themselves in their Goods out of the way ahead of schedule we worry about what happens if the train runs earlier late but apparently this hasn't been a big problem so far the railway market is known as the most dangerous market in the world and it's only through the sheer stubbornness of the traders that it hasn't been closed down and moved elsewhere we're not sure we'd want to eat any fruit or vegetables after trains past a few inches above them there's a famous building in Boston USA that's gone by many names over the years most people call it the John Hancock Tower but it's also gone by 200 Clarendon Street the X building because of its iconic braces and the Hancock unfortunately it's also very well-known because of some shoddy construction work that went on during its construction during the 1970s whoever was in charge of securing the windows and window frames on the upper levels of the skyscraper didn't do a very good job of it and as a result several large window panes fell out of their frames and plummeted all the way to the busy sidewalk below miraculously nobody was hurt that was one more embarrassment on top of a whole series of them for the architects who didn't deliver their completed building to the city until 1976 it was supposed to be done in 1971 and the five-year delay saw the project go 100 million dollars over budget even when it did open it's weighed so much in the wind that occupants on the upper levels suffered from motion sickness fortunately those issues have all now been resolved not even Disney has a magic touch all the time when it comes to completing large projects on time or as originally envisaged anyone who lives in or around the Walt Disney Concert Hall in downtown Los Angeles California can attest to that it was 1992 when construction work began sparked by a 50 million dollar donation to the city of Los Angeles by Lilly and Disney the widow of Walt it didn't welcome its first guests until 2003 eleven years later by that point it had cost two hundred and seventy four million dollars with the parking garage somehow managing to cost a whole 110 million on its own nearly every cost provided at the design stage had been underestimated and the project stalled completely between 1994 and 1996 as additional funds were sought to finish the job when work resumed the expensive and lavish carved stone exterior had to be abandoned and replaced with stainless steel this was problematic the concave sections of the outer walls reflected and intensified the Sun heating up the sidewalks directly opposite them up to 140 degrees Fahrenheit and almost blinding residents of neighboring condominiums the offending surfaces were eventually sanded down and all is now well staying in the United States of America for a moment if we move to Chicago will find the Aon Center which was once known as the Amoco building the 1,100 foot tall building is the fourth largest skyscraper in Chicago but back when it was built in 1973 it was the fourth tallest in the whole world that made its opening a grand affair but it almost didn't make it to its opening day after some pretty serious mistakes were made during construction the building was clad in Carrara marble but marble that Finn had never been used to clad a building so tall before it turned out that it wasn't suited to the job a 350 pound slab of the material fell from the tower on Christmas Day in 1973 and crashed through the roof of the Prudential Center by 1985 by which time the building was open and in regular use a routine inspection found dangerous cracks and signs of bowing on several of the largest marble panels the building had to be strapped in stainless steel to prevent the marble from falling off and the whole structure was eventually resurfaced with a different form of marble in 1992 we expect architects to take sensible precautions whenever they design anything expected to be used by humans but we'd expect them to be particularly careful if they are putting together something that will eventually be used by children sadly they don't always do in 2010 parents of children in the Brooklyn area of New York USA were furious about a new playground that had been installed at Brooklyn Bridge Park with its shiny chrome design it looked futuristic and stylish but somehow the designer team responsible for it had forgotten that steel gets very hot when the sun's out at the warmest times of the day the parks claiming domes became so hot that any child who came into contact with one would be likely to receive burns immediately to make matters worse the climbing domes were supposed to be the main form of entertainment for the park's young users the local authorities decided to solve the problem by planting trees close to the to provide shelter but even now 10 years later it said that the trees don't completely solve the problem if you were tasked with designing a bridge to carry tourists through a busy part of Venice bearing in mind that Venice is one of the most popular vacation destinations in all of Italy your first job would be to ensure that your bridge design could cope with lots of people attempting to walk over it at the same time Santiago Calatrava somehow failed to do that when he designed and built a glass bridge in 2008 and after tourists were injured crossing his slippery unstable bridge he was fined more than 150 thousand dollars the architect told authorities that the glass steps on his bridge would need to be replaced once every 20 years but instead eight of them had to be replaced at just four years after the bridge opened whenever it rains the glass becomes impossible to maintain balance upon making crossings hazardous when seen from a distance it's a very aesthetically pleasing bridge but with so many problems you'd think twice about crossing it it's generally thought that while it's still imperfect it's safer today than it was ten years ago have you ever woken up in the morning and wished there was a train that took you directly from your front door to your place of work if so perhaps you should consider moving to Chong Shing in China where there's a train line that runs directly through the middle of an apartment building we don't know whether to call this a design disaster or a design triumph it's convenient for all the people who live inside the apartments but no matter how well designed it is the constant passage of the trains must surely be causing structural damage what makes this arrangement so remarkable is that the nine story apartment complex was there before the monorail was Chong Jing wanted to expand their local railway service in 2004 and originally intended to tear the apartments down but they eventually reconsidered and found another way to do it this is that other way while you might expect the value of your property to be reduced if someone decided to build a busy railway line through it apparently apartments in this complex have increased in value because of both the novelty and the convenience if you really loved your house how far would you go to resist any attempt to have it bought out from underneath you so it could be knocked down do you think you'd be able to hold on even if you were offered three or four times the value of what your house was really worth this is a question that comes up a lot in China which is full of so-called nail houses nail houses appear in areas that have been earmarked for construction work such as a new highway but the houses belong to people who have refused to accept offers of compensation from builders and chosen to remain in their homes one particularly notable example is this free-standing house in the middle of the asphalt in when Ling which belonged to an elderly man named Liu balgan and his wife all of Lu's neighbors took the money and gave up their houses but he wasn't for moving and he stayed put while the road was built all around him eventually years after the dispute started in 2012 he accepted a vastly inflated price and moved this house is now gone but there are still plenty more all over the country [Music] subscribe to the channel and turn on notifications and you will be the first to know when a new video comes out thank you for watching and see you soon
