After the construction of the defense line in the Middle East began to proceed smoothly, Chen Xin couldn't help but have some ideas about the dome urban design drawing that was turned out and reorganized.

The country wants to restart the construction of the dome city, and he has confirmed this intention to the senior management that the senior management does have this idea, but the senior management wants to adjust the original design plan of the dome city.

As mentioned before, this design plan was originally experimental, with the purpose of studying the coexistence and reunion between humans and the ecological environment, and the recovery of the ecological environment after disasters.

According to the initial design, the dome city is not finished after it is built. A large number of scientific research institutions and staff will also maintain it, and breed and reproduce species in it to establish the ecosystem designed by Chen Xin, so that it can maintain itself and maintain stability.

Overall, this is not so much a city as a large research facility.

For the current Yan Kingdom, the reconstruction of the dome city is obviously not to continue this research project, but to accommodate the people.

Since the sky was purified and the sun rose again, the country has actually been planning to get the people living underground back to the ground.

After all, it is well known that people need to bask in the sun. Living underground for a long time will have various negative effects on the body. There is no way to live in an underground shelter in order to survive, but if the situation improves, people should still be allowed to return to the ground to live.

In fact, after the sun comes out, people in some areas and cities have begun to transform the shelter where they live, preparing to return to life on the ground.

If it weren't for the war with alien creatures, the country would have wanted to advance this aspect long ago.

The reboot of the construction of the dome city is an attempt to make this purpose.

After all, except for the extra cover on the head of the dome city, life is basically no different from that of the cities before the disaster.

Therefore, it is now necessary to adjust the functions of dome cities, from experimental scientific research cities to more professional and more relevant living cities.

This is actually not difficult to achieve. The Dome New City is such a city. The Dome New City, which has accommodated more than 100,000 immigrants, is now an absolute life city. However, in some aspects, it is different from a simple life city due to the limitations of the original urban design and the need to support wars.

The drawings after Chen Xin's "optimization" again are very suitable.

After all, this is a city designed simply to accommodate population and meet life needs.

This drawing was not only sent to the senior executive who was responsible for the defense line in the Middle East, but also received the drawings in the domestic high-level executives.

However, the cost of dome cities is still too high. Even if the domestic can afford the cost of building a new dome, it is still a heavy burden.

So the senior management expressed to Chen Xin whether it could reduce costs, hoping that he could optimize the drawings again, so that the country could afford the expense of building two dome cities at the same time.

Chen Xin did not refuse this request from the senior management, but this was not easy to achieve.

If you want to reduce construction costs, in addition to reducing material investment, you will also compress labor costs. After all, these are the main costs in construction. The land does not need to be included in the cost now. The land belongs to the country and does not need to be counted on money.

However, both materials and labor are not easy to compress.

In terms of labor costs, there is actually no room for compression, unless it is said that the current construction method can be improved on a large scale and more work can be completed with fewer workers, so that the cost can be compressed.

But this is not something that can be done easily, and even if labor costs are compressed, it will definitely not meet the requirements that the country that the top leaders hope can bear to build two dome cities at the same time.

After all, labor costs do not account for the dome city, and the greater cost is actually the materials used to build the dome.

When Chen Xin first designed the support structure of the dome, he chose lightweight materials, and even the outer layer of the dome was made of EFTE airbags and lightweight insulation materials instead of heavier materials such as glass.

These lightweight materials greatly reduce the weight of the dome itself, and also maintain sufficient structural strength. With some designs added by Chen Xin later, this is the large dome of the Dome New City that protects more than 100,000 people in the entire city.

However, the use of this part of the materials is also part of the largest cost of dome city construction.

These materials themselves were relatively expensive materials even before the disaster. However, at that time, there was enough industrial scale to mass production, so the cost could naturally be suppressed to an acceptable level.

But the current industrial scale is obviously not as good as before the disaster, and the domestic industrial production capacity also needs to support both the European and Middle East aspects, so there are not many resources that can be squeezed out.

If the cost cannot be compressed, with the current ability of the country, it can only afford the construction of a dome city, and it is even a bit tight.

However, if these materials are replaced with cheaper materials, it will affect the weight and structure of the dome. If you want to do this, you must overturn the original design, which is equivalent to pushing everything back.

This is not something that can be easily accomplished even for Chen Xin.

However, he still summoned researchers from relevant departments to study this issue and see how to meet the requirements put forward by senior management.

The first thing that was raised was construction issues. Some people think that the current 3D printing technology can be used for the construction of dome cities. After all, this printing technology is not only convenient, but also saves more labor investment.

Chen Xin quickly adopted this suggestion and designed a new 3D printing equipment that can be used for dome construction. As long as the materials are complete, the support structure of the dome can be printed directly.

But this is not enough. Although doing so effectively reduces some construction costs, it still fails to meet the standards required by high-rise buildings.

If you want to truly reduce the cost, you still have to make a fuss about the materials.

However, in the face of this problem, the researchers summoned by Chen Xin proposed two completely opposite solutions.

One party hopes to develop new materials. As long as it can develop materials that also meet construction requirements and are at low cost, it can achieve high-rise requirements.

On the other hand, we hope to work hard on the structure. By optimizing the structure, replacing the originally relatively expensive materials with cheap materials can also meet the requirements of high-rises.
