So why are you buying into the idea mankind can't do what they did 2,700 years ago?Here in the 21st century we can't build a wall?An Engineer Explains Why Trump’s Wall Is So Implausible
There are very few occasions in American political discourse that require the input of a structural engineer, but when Donald Trump took a question from Univision’s Jorge Ramos regarding his proposed United States-Mexico border wall at a press conference on August 25, I heard the clarion call:
RAMOS: How are you going to build a 1,900-mile wall?
TRUMP: Very easy. I’m a builder. That’s easy. I build buildings that are — can I tell you what’s more complicated? What’s more complicated is building a building that’s 95 stories tall. Okay?
No. Donald Trump is not a builder. Donald Trump could not build a doghouse. Donald Trump is a developer who pays what he would call “very, very smart people” to build things on his behalf. His response to Ramos’ question was meant both to exaggerate his understanding of construction and to downplay the challenges posed by his border wall project.
The challenge of Trump’s border wall is not technical, but logistical. The leap in complexity between “building a wall” and “building a 2,000-mile-long continuous border wall in the desert” is about equal to the gap between “killing a guy” and “waging a protracted land war.” Trump’s border wall, if built as he has described it, would be one of the largest civil works projects in the history of the country and would face an array of challenges not found when constructing 95-story skyscrapers.
Trumpery has no intention of "building a wall" but this thread is about the logistics of this fantastical project. John Oliver's segment explained many of the same things but this is more detailed. Even fans of Trumpery's trumpery will see why most people laugh at the idea of The Great Trump Wall.
Good thing the Chinese didn't hear that 2,700 years ago.
Israel built a 500 mile wall. Hardly an engineering feat.
Great Wall is 13,171 miles long.
Is our southern border longer than that?
How Long It Took to Built the Great Wall of China
It is actually a complicated question. There are several Great Walls that were built by different dynasties such as the Qin Great Wall and the better known Ming Great Wall. But there are estimates about the number of laborers and records for how many years it took to complete the work...
Construction Time For All of the Walls
If all the fortified walls that were built by the different dynasties and kingdoms around northern China are included, the total length would exceed 20,000 kilometers (12,000 miles). All these walls together were completed over a period of 22 centuries. It is probably impossible to calculate how many millions of people built the Great Wall or the man hours expended.
I'm not.
I have no doubt that we could build a 12K mile wall over a period of more than 2000 years.
With todays equipment and materials, I'm fairly sure we could build one in far less time.
