The third building is even more admired by Chu Feng, there are a total of forty-eight sections in the shape, each section is a four-sided diamond, and the top of the building is composed of three-sided diamonds, so no matter from which point of view, you will feel that this building is facing you on the front, especially each four-sided diamond is fitted with a silver-white metal border.

The silver-white metal frames of the third block are not only beautiful, but also play a role in fixing the glass curtain wall, and from the three-dimensional renderings on the curtain wall, these silver-white metal frames are very cleverly embedded in the glass curtain wall.

From a distance, it looks like a slender diamond-shaped sapphire building, inlaid with an alloy frame full of art and science fiction, which is extremely sci-fi.

"Very aura design, the whole building is so simple that there is nothing superfluous, there is no advertising curtain wall and no transmission tower, just ......"

Chu Feng rotated the building through the control panel, looked around carefully, and said uncertainly: "The design of these silver-white hollow metal strips is very eye-catching, and I am also very interested, but the size is so huge, are you sure you can process it?" ”

"No problem." Li Yi Neng said with confidence.

"I dare to say that just for this appearance, I can win the Luban Award and the Zhan Tianyou Award, and I think it is most likely to win the Liang Sicheng Award, after all, the design of this building is very sci-fi." Li Yineng continued, in fact, he still has a sentence to say, the more chic the shape, the more difficult the construction, especially the construction of the main and secondary sorghum.

The main reason why it is difficult to be ingenious in the design of skyscrapers is that the designers must compromise the appearance of the building with wind speed and earthquake intensity.

Just like the shape of the aircraft, the design comes and goes, it is basically a mold, the third generation fighter is like this, and the fourth generation fighter is the same, all of which are in pursuit of faster and more stable.

Because of the appearance of the fighter jet that is most suitable for aerodynamic shape, there are only a few that are turned over and over, and the wind blows over the surface of the building to create a load, and then the vortex falls off on both sides of the building.

From Li Yineng's professional point of view, the shape design of this building is indeed very bold, and it is also a scheme designed by Wu Xiaohan, she has always liked to use a polygonal design to break up the spiral nest, which is theoretically feasible.

However, the damper of the building had to be re-designed, and a 1:500 scale model of the building had to be made and sent to the building wind tunnel laboratory to simulate the actual wind conditions of the building.

Secondly, it is necessary to carry out seismic experiments, many buildings are strengthened on the ground floor, in order to enhance the earthquake resistance, take Jinmao Daxia as an example, the seismic degree of Jinmao Building can reach 7, and the wind degree of the building reaches 14.

"Wind tunnel experiments can be done in Lushi, just three days after our company, there is a 204-meter-high building to carry out wind tunnels and seismic experiments, back I asked the company to work overtime, try to make the building model you want, and send it into the wind tunnel and seismic experiments together."

Li Yineng took a sip of the mineral water on the table: "Only by getting the detailed parameters can our company start the design of the building damper." Before that, we can first design the drainage system, air conditioning system and water and electricity system, as well as the electrical wiring. ”

"But if the building design is to be carried out to such an extent, in terms of air conditioning system, I can recommend to you the superconducting water circulation air conditioner of the Gree brand, which is the kind at the exhibition last time, it is much more power-efficient than similar products, oh yes, I forgot that you have not been to the exhibition, but Mr. Gao should understand the advantages of superconducting water circulation air conditioning."

Chu Feng looked at Gao Feng, Gao Feng nodded, the refrigeration effect of those air conditioners at the beginning also left a deep impression on him. Although the Gree brand once had the scandal of resonance causing the stent to fall off, it was not a defect of the product itself, it was a coincidence, but because it was put on the Internet by netizens, many people had a bad impression of the Gree brand.

Of course, for Gree, this kind of metal coincidence, in their eyes, it is impossible to exist here, the building purchase order is a big order for Gree, and Gree attaches great importance to this kind of order, if it does not pay more attention to this aspect, it will have been eliminated by the market ten years ago, even if it has Dong Mingzhu sitting in Gree.

The video on the curtain wall is only a complete three-dimensional drawing, as well as the design interior view of the private living area on the top floor of the building, and Chu Feng needs to reserve space for the installation of scientific and technological equipment in the building, and at the same time, it is also necessary to ensure that the future building can meet the needs of the biological laboratory and R&D testing room can be carried out smoothly and secretly.

In addition, Chu Feng also wanted to plan to put forward the illusion of his personal living area on the top floor, that is, the 68th floor, which has a sky swimming pool and a sky garden, and also needed to reserve fire hydrants and fire escapes to ensure that the fire audit could pass the inspection.

Yes, the third building is 366 meters high, with 68 floors on the ground, plus a 3-storey underground garage, a total of 71 floors, covering an area of more than 120,000 square meters, and the actual total building area is as high as 8 million square meters, which is the largest in the world.

Therefore, the negotiation between the two sides lasted for two hours, and then entered the most important moment - to negotiate the price.

In fact, the charging standards of domestic design companies or design studios are charged according to the square, according to the level and technical difficulty, the price difference per square meter is amazing, although they signed a contract before.

However, it was an old contract of 42 floors, and now that you choose a higher skyscraper, you will naturally have to revise the contract and sign a new one.

A building with a height of more than 300 meters can be called a skyscraper, and it just so happens that the skyscraper is a kind of high technical difficulty, and the boss of the design company, Li Yineng, walked back and forth with an empty cup for a long time, and wanted to open his mouth several times, but frowned a little embarrassedly.

"75 pieces of a flat!" Considering that in the end, Li Yineng put down the teacup and explained to Chu Feng: "Of course, this price includes a full set of construction specific drawings, wind tunnel and seismic test fees, as well as unlimited free modifications. ”

The total construction area of the building that Chu Feng wants is more than 8 million square meters, and according to the design cost of 75 yuan per square meter, the final design fee is as high as 600 million, plus the 100 million contract signed before signing the old contract, in the end, Chu Feng will have to pay 500 million more building design fees.

This price sounds terrible at first glance, the design fee of a building can cost 600 million yuan, which is simply more than a robbery, but the market is like this, some multinational design companies are responsible for the design of terminals, high-speed rail stations, and the price per square meter can even reach 500 yuan per square meter, and what is more excessive is that although the domestic design fee seems expensive, it is actually the cheapest.
