Today I want to share with you some of the most famous engineering marvels around the globe and the tremendous effort and cost behind them. Of course, including both success and failure, and the world's most serious mistake in the project, which cost a huge amount of money, has added a bad debt after completion, and China has 2 monopolities, so what are they?
There are some buildings in human history that are like dazzling pearls, shining and attracting people's attention. However, just like the shadows in the sun, there is much to ponder behind them. Accidents or mistakes in these projects are all touching. Let's demystify each of them in the hope that we can learn from them.
As one of the oldest and greatest buildings in the world, the pyramids are undoubtedly the crystallization of human wisdom and perseverance.
They have survived thousands of years of wind and rain and still stand on the land of Egypt, and these seemingly impregnable structures have actually suffered many earthquakes and sandstorms.
The worst of these occurred in the 9th century, when an earthquake caused a large number of pyramids to crack and repair them for a long time and with great difficulty.
Next, we will set our sights on the Great Wall of China on the mainland. This great project embodies the outstanding creativity and construction skills of the Chinese nation.
However, due to the low socio-economic and technological level at that time, it was inevitable to encounter setbacks and difficulties in the construction process.
Among them, the most representative case is the "Qiqi" section of the Great Wall built during the Ming Dynasty, which is an astonishing 70 kilometers long.
This feat has been controversial since its inception because it is too much about length and neglects safety and stability. In addition, many parts of the Great Wall were built on cliff faces, making construction more difficult and risky.
The most famous of modern greats is the Burj Khalifa in Dubai, which is billed as the "tallest building in the world" at 828 meters.
However, the numerous fancy features made the Burj Khalifa, which lacked sufficient physical support, a fragile structure, and unfortunately a serious elevator accident left 16 people dead.
This incident has revealed a very important question for us: how do we balance the safety of buildings in the pursuit of innovation and speed?
While acknowledging the contributions of these historical sites, we have to admit that some of the projects have problems and regrets.
For example, the Statue of Liberty in the United States, although majestic, has caused controversy and even complaints about its nightfall light show. From this point of view, it is not enough to have a good technical or aesthetic design.
Of course, in addition to these very successful buildings, and some of them have shortcomings, and some of them are a complete waste of human and financial resources, which is a huge failure.
Among them, the world's major projects, let's look at the top five, China accounts for two.
One is the Sky City of Changsha.
Changsha "Sky City" was originally an ambitious and ambitious project to create the world's tallest skyscraper and challenge the pinnacle of human architectural history.
From the very beginning of its design, this remarkable honor has attracted countless attention from all over the world.
However, despite the fact that the project was already in the works before 2015 and there are even rumors that it is underway, unfortunately we have not seen any traces of the construction of the so-called Sky City so far.
It is worth mentioning that the miscarriage of Changsha's dream of "sky city" is more due to the interruption of the capital chain and the collective withdrawal of investors.
According to relevant reports, COSCO Technology Group invested about 5 billion yuan in the project, but it was built in a highly controversial way of environmental protection and energy saving.
In the end, the construction was stopped because this plan aroused doubts from experts in geology, construction and other aspects.
It is now in ruins, and although it does contain hopes and hopes for the future, these have now caused endless sighs and worries.
Although the Changsha "Sky City" project has come to an end, its lessons are worth reflecting on. What we are facing is not only a short period of excitement blown by a gust of wind, but more importantly, the reasonable evaluation and careful thinking of various construction projects, especially when it comes to large-scale investment, we should examine whether it is feasible and whether it can truly serve the society and benefit the public.
The second is the most outrageous bridge project in the world to date.
The Tacoma Narrows Bridge, known as one of the most unique structures in the world for its unique form, is known as the "swing in the wind", hence the name.
As the name suggests, swings are undoubtedly a common form of entertainment in our daily lives, and the suspension bridge actually hovers in the air, swaying in the wind like gummy candy.
Located in the beautiful state of Washington, the bridge has been in use since 1940 and is highly regarded for its engineering quality and technology.
As the political center of the United States, the city has been fully guaranteed and supported, from the design concept to the choice of materials, as well as the need for funding.
The entire bridge is constructed in the form of a two-sided suspension bridge, which is designed to alleviate the pressure of regional traffic congestion and provide support for the country's outstanding livelihood projects.
When the project was completed, the citizens welcomed them warmly, and they drove their vehicles across the bridge with anticipation, but what happened next surprised everyone.
It is understood that the bridge underwent two redesigns during the construction phase, most of which were due to the designer's insistence on making the bridge a picture rather than just a transportation function.
León believes that despite the important practical value of the bridge, its aesthetic effect cannot be ignored at the same time, since the bridge has the potential to become one of the symbolic buildings of the capital.
Therefore, he decided to experiment with different curves in his design and use high-quality materials.
At that time, Leon had already won wide recognition in the industry, so the public believed in his suggestions and chose to accept his design.
Another designer, however, strongly believes that a more secure approach should be taken, focusing on ensuring the safety of the bridge, with function as the key factor, and aesthetics not as the key factor.
This idea, although controversial at the time, was confirmed in practice.
However, there is a clear discrepancy between the low-key design and the public's expectations, which directly leads to the fact that the bridge has not been universally recognized by the public since it was put into operation.
As a result, quite a number of citizens have blamed the quality of the Tacoma Narrows Bridge, claiming that cutting corners led to the collapse of the bridge.
However, after an in-depth investigation, it was determined that this was not the case, and that the Tacoma Narrows Bridge was built using state-of-the-art material technology, and the entire construction team was fully committed to the construction of the project.
Contrary to expectations, after more than a year, the bridge finally failed to escape the fate of everyone's hatred, and the repeated winds caused the shaking and finally caused a tragedy.
The third, the Dubai Palm project, Dubai is really a mixed bag, with successful cases like the Burj Khalifa and failures like The Palm.
The 3,000-square-kilometre mixed-use project was originally designed to be a luxury retreat and a new cosmopolitan image for the city.
However, it is a pity that for various reasons, this project has finally become an unsolved historical unsolved case, and has become a "public unfinished project" in the eyes of many people.
The overall investment in the project is a staggering $14 billion, including land costs, infrastructure development, and ecological and environmental protection.
Because of this high investment, the construction process of the project seemed to be stretched, and there was not enough space and time to adjust and refine the details.
In addition, because the project is too large, it consumes a lot of resources that could be used in other fields, and many people have concerns about its sustainable use in the future.
Secondly, there are also some problems in the design process. Due to the limitations of topographic and climatic conditions, the initial design scheme did not fully take into account the practical difficulties, resulting in frequent unexpected conditions during the construction process, such as geological disasters and tectonic deformations.
These problems once brought the progress of the project to a standstill, and even raised widespread doubts about the stability and safety of the entire project.
Finally, in the follow-up operation and management links, it is also because of the failure to detect and correct the poor performance or non-standard operation behaviors in time, or because of the lack of scientific and reasonable institutional model to promote and guide, resulting in the unwarranted loss of resources and reducing considerable economic benefits.
The Dubai Palm project took more than a decade, but unfortunately it could not usher in a glorious end.
Some people say that the scale of investment is too large, or that there is a mistake in the design, and some people say that it is due to improper operation management...... Whatever the reason, however, this harrowing history is a wake-up call.
It reminds us that when embarking on any important project, no matter how big or small, we need to carefully assess all aspects of risk and pursue a balance between investment and return to achieve long-term stable and sustainable development.
Only in this way can we ensure that the construction of the project becomes a truly meaningful cause, so as to truly benefit mankind and promote social progress.
All in all, the history of the ups and downs of the Dubai Palm project has given us a profound inspiration, and while planning the future blueprint, we must keep in mind the scientific and reasonable development and management principles, fully refer to the lessons of the past, and treat every link prudently.
Fourth, there is the three bridges of the Qianjiang River in China, when you mention it, you must be able to think of this important urban transportation hub, which cost a huge amount of manpower, financial and material resources, but collapsed overnight.
This catastrophic event touched the hearts of countless people, because it is not only an important landmark of Hangzhou, but also one of the important bridges connecting the city's economic activities, and plays a pivotal role in promoting transportation flow and economic development.
However, when we look back at this incident, we realize that the complex factors behind it are far more complex than we imagined.
It turns out that the Qianjiang Third Bridge has adopted quite advanced cable-stayed clue bridge technology as early as the design stage, and it is precisely because of its beautiful and majestic shape and high practicality that this bridge has won many honors in the architectural world.
Unfortunately, however, the bridge had already accumulated a series of problems in the early stages of construction, such as poor construction quality, poor material quality, and inadequate supervision.
Although these problems had arisen since the time of the bridge's construction, they were never properly addressed, culminating in this major accident.
More importantly, we must not forget the immediate cause of the accident.
According to the results of the investigation, the main cause of the collapse of the bridge was not overloaded trucks, but existing construction and management problems. Overloaded trucks were nothing more than the last straw that broke the bridge.
It is worth noting that after the completion of the Qianjiang Third Bridge, despite repeated repairs, the wall safety problem still exists. Moreover, some officials and engineers have even been implicated in corruption, which has exacerbated the problem.
In the whole construction process, the lack of supervision of the project undoubtedly buried a deep hidden danger for the occurrence of the incident.
Although we do not yet know the specific damage caused by this accident, it is certain that this bridge, which cost huge manpower, material and financial resources, eventually became an unacceptable "mess" due to irresponsible construction and supervision and management.
Moreover, the price does not stop there, it wastes a lot of national investment, and it pierces the hearts of tens of thousands of people.
Nevertheless, we still need to learn from this incident. In the face of large-scale engineering projects, we must always keep in mind the principle of quality first, strictly control the quality of all links, especially the quality of production procedures and processes, and do not allow the slightest negligence.
In addition, strengthening supervision is also an essential measure. Government departments should strengthen supervision, crack down on all kinds of violations of laws and regulations, ensure the smooth implementation of engineering projects, and avoid the recurrence of similar incidents.
At the same time, the public should also improve their legal awareness and ecological protection awareness, establish correct values and consumption concepts, not blindly pursue luxury and waste, but respect the laws of nature, care for the ecological environment, and jointly promote sustainable development. Only when everyone can do the above can we truly realize our vision of a better home.
All in all, the ruins of the three bridges on the Qianjiang River remind us that we must not be sloppy in the construction of large-scale projects, and we must establish and improve a scientific and rational management system, strictly implement various rules and regulations, resolutely safeguard public interests, and shoulder due social responsibilities.
At the same time, it is also necessary to establish a sound supervision mechanism for the whole process of procurement, acceptance and construction to ensure the calibration of the optimal construction plan, build a first-class engineering construction team, and build high-quality engineering projects.
Finally, I hope that each of us can think deeply from this incident, take active action, and work hard to realize the Chinese dream and create a better future!
Welcome everyone to put forward new ideas, your support is the motivation for me to continue to create, thank you!
