"Kilometer ......"

Academician Wu Xian lifted his glasses and was silent for a while before saying: "From the perspective of engineering technology alone, it is completely fine to build a kilometer building. ”

"But the cost is ...... IMHO, although Vientiane is very profitable, it is indeed a bit impractical to build such a building. ”

Lin Han said: "As far as I know, the world's tallest building, the Burj Khalifa, which is more than 800 meters high, took five years and cost only about 1.5 billion US dollars. ”

"Spending $1.5 billion over five years doesn't seem like an unaffordable price. ”

Academician Wu waved his hand: "It's different." ”

"First of all, this landmark in Dubai is the 'tower', since it is a tower, the total area is relatively small, and the building depends on the total area in addition to the height. ”

"In addition, for super high-rise buildings, wind is the biggest limit to increase height, and the structure of the tower is more conducive to resisting wind loads, which can save some money. ”

Academician Wu paused, and then said: "Moreover, Dubai is far away from the seismic zone, and the seismic fortification intensity is only six degrees. ”

"In comparison, the seismic fortification intensity in China's capital is eight degrees, seven degrees in Shanghai, and nine degrees in parts of Sichuan Province......"

"Yunzhou City is close to the Tanlu seismic zone, and the Tanlu seismic zone has been listed as a key monitoring area by the National Earthquake Administration since about 30 years ago, and the fortification intensity must be guaranteed to be seven degrees. ”

When Lin Han heard this, his face couldn't help but change: "Then what do you estimate about how much it will cost to build a kilometer-high skyscraper in Yunzhou City?"

Academician Wu Xian pondered for a moment: "The central building in Shanghai has a total height of 632 meters, a structural height of 580 meters, and a total cost of 14.8 billion ...... Take a cursory look, you plan to build a kilometer building, and two or three hundred billion is just a conservative estimate. ”

A conservative estimate of two or three billion ......

Lin Han couldn't help frowning slightly when he heard this, and fell into deep thought.

Cleaning up about one-third of the country's invasive species, this wave can probably earn more than 3 billion yuan, counting the previous accumulation, he gritted his teeth, and 5 billion can still be smashed.

But these two or three billion are indeed not something that can be taken out in a moment and a half. What's more, even if he had this money, he couldn't have smashed it all on the skyscrapers.

Academician Wu smiled at this time: "I personally don't recommend that Vientiane build such a kilometer building now, otherwise you will continue to invest two or three hundred billion yuan in the next five years, with an average of more than 5 billion yuan per year." ”

"In case the middle of the fund breaks, it will be another giant mansion...... Although there are some government reasons for the bankruptcy of the Giant Mansion project, Comrade Kobayashi, I think it is better for you to be cautious. ”

More than 20 years ago, Shi Yuzhu invested in the construction of Giant Building, with a total investment of 1.2 billion.

However, due to various reasons, the funds were broken during the construction process, and the Giant Building, which had invested 300 million, was forced to become an unfinished building.

Shi Yuzhu, who was a huge wealthy man at that time, was also in countless debts overnight and became the "first negative in China".

Of course, this unyielding "first loser" later made a comeback by virtue of marketing health products such as "brain green gold", not only paid off all the arrears, but also became a generation of super-rich again.

Academician Wu continued: "Yunzhou is a third-tier city after all, in fact, just build a two-hundred-meter skyscraper, it is more than enough. ”

"CCTV's headquarters building is only more than 200 meters, if you choose a tower building structure, not only the stability can be greatly improved, but the construction cost can also be saved a lot. ”

It seems that this is the only way to do it for the time being.

After all, the kilometer building, such a majestic world-class building, even if it is built, whether it can be fully utilized in Yunzhou City remains to be said.

Although he was a little disappointed, Lin Han also understood the truth that he couldn't be ambitious, and immediately nodded: "In this case, I wonder if you can recommend a designer to me?"

Academician Wu Xian thought for a while, and then smiled: "I have a student named Tan Jianfeng, he studied civil engineering at Nandong University in Handong Province for his bachelor's degree and master's degree, and his doctorate was in architecture with me, and he is now working in Guangzhou. ”

"He has a deep study of supertall buildings, and is even a bit of a fanatic...... Moreover, I remember that his hometown seems to be Yunzhou, and there should be no more suitable than him. ”

……

After Mr. Wu's introduction, Lin Han contacted Tan Jianfeng the most, and the two met at a hotel in Guangzhou.

However, what surprised Lin Han was that this Tan Jianfeng was not only from Yunzhou, but also from high school.

Actually, it's normal to think about it. In a series of entrance exams, after layers of selection, most of the top students are finally concentrated in prestigious schools, whether they are in universities or middle schools, and even in elementary schools to some extent.

Qinglin County Middle School occupies the first place in Yunzhou City, but most of those who are admitted to key universities from Yunzhou come from this school.

Within a few days, the moment Lin Han saw Tan Jianfeng, he understood why Academician Wu said that he was "a little fanatical" about super high-rise buildings.

Senior Tan...... Hello. ”

Lin Han raised his head and looked at the man in front of him, who was more than 2 meters tall, and couldn't help but feel a little embarrassed.

"Hello Mr. Lin. ”

Although Tan Jianfeng is tall, his face is quite gentle, wearing a pair of black-framed glasses and smiling.

The two shook hands, and Lin Han felt as if his hand was being wrapped in a huge grinding disc.

After taking his seat, Tan Jianfeng said: "On the phone before, you said that Vientiane is going to build a landmark in Yunzhou, two hundred to three hundred meters, right?"

Lin Han nodded: "Originally, I wanted to build a kilometer building, but after learning about Academician Wu, I decided to ......."

"Kilometer Building?"

Tan Jianfeng seemed to be stunned for a moment, and then his eyes seemed to shine, and he said, "Do you really plan to build a one-kilometer-high building?"

"Originally, I had this plan, but considering the actual conditions, I felt that it would be more appropriate to change it to more than 200 meters, and it was best to build a tower. ”

Tan Jianfeng frowned slightly, was silent for a while, and then asked: "Then what about in the future, do you still want to build a kilometer-level mansion?"

"It depends on the situation, after all, it is a world-class super-giant construction project. A building of tens of billions is about to catch up with the Qinghai-Tibet Railway. ”

Tan Jianfeng coughed twice: "The kilometer-level building is actually likely to be much more expensive than the Qinghai-Tibet Railway." ”

Lin Han was stunned: "Have you made specific calculations?"

"Of course I did, and more than once. Tan Jianfeng seemed a little excited.

"When I was just starting my master's degree, I set out to design a special kilometer-level skyscraper plan, which was revised and modified until last year. ”

Lin Han couldn't help but ask, "Something special?"

Tan Jianfeng hesitated for a moment, stared at Lin Han for a while and said, "You tell me first, if you plan to build a thousand meters in the future...... No, it's a kilometre building?"
