Chapter 827: reduce costs

After the construction of the defense line in the Middle East began to go

smoothly, Chen Xin couldn't help but have some ideas on the design of the dome

city that was turned out and rearranged.

The country wants to restart the construction of the dome city. He has

confirmed this intention to the senior management. The senior management does

have this idea, but the senior management wants to adjust the original design

of the dome city.

As I said before, this design plan was originally experimental. The purpose

was to study the coexistence between humans and the ecological environment, as

well as the restoration of the ecological environment after a disaster.

According to the original design, the dome city is not finished after it is

built. There will be a large number of scientific research institutions and

staff to maintain, and cultivate and multiply species in it to establish the

ecosystem designed by Chen Xin. Able to self-circulate and maintain, and

maintain stability.

In general, this is not so much a city as it is a large research facility.

For the current Yan country, the restart of the construction of the dome city

is obviously not to continue this research project, but to accommodate the

people.

Since the sky has been purified and the sun has risen again, the country has

actually been planning to bring the people who live underground back to the

ground.

After all, as we all know, 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 underground shelters, but if the situation improves, the people

should be returned to the ground again. Living.

In fact, people in some regions and cities have begun to transform their

shelters after the sun has reappeared, and are preparing to return to life on

the ground.

If it hadn't been dragged down by the war with alien creatures, the country

would have already wanted to move forward in this regard.

Restarting the construction of the dome city is an attempt for this purpose.

After all, life in the dome city is basically no different from the city

before the disaster, except for an extra cover above the head.

Therefore, it is now necessary to adjust the functions of the dome city, from

an experimental scientific research city to a more professional counterpart

living city.

This is actually not difficult to achieve. The current Dome New City is such a

city. The Dome New City, which has accommodated hundreds of thousands of

immigrants, is now an out-and-out living city, but in some respects due to the

limitations of the original urban design. And the need to support war

operations at the beginning is different from a simple living city.

The drawings after Chen Xin "optimized" again are very suitable.

After all, this is a city designed simply to accommodate the population and

meet the needs of life.

This drawing was not only sent to the high-level man in charge of repairing

the defense line in the Middle East, but the domestic high-level also received

the drawing.

However, the cost of the dome city is still too high. Even if the country can

afford to build a new dome, it is still a heavy burden.

So the high-level officials expressed to Chen Xin whether they could reduce

costs, hoping that he could optimize the drawings, at least so that the

country can afford to build two dome cities at the same time.

Faced with this request made by the senior management, Chen Xin did not

refuse, but it was not easy to achieve.

In order to reduce construction costs, in addition to reducing material input,

it is to reduce labor costs. After all, these are the main costs of

construction, and the land does not need to be included in the cost. The land

belongs to the country and does not need to be counted.

However, no matter whether it is material or labor, it is not easy to

compress.

In terms of labor costs, there is actually no room for compression, unless it

is said that the current construction methods can be improved on a large scale

and more work can be done with fewer workers, which can reduce the cost.

But this is not something that can be done easily, and even if labor costs are

reduced, it will certainly not meet the high-level expectations that the

country can afford the construction of two dome cities at the same time.

After all, labor costs do not account for the bulk of the dome city, and the

greater cost is actually the material used to construct the dome.

When designing the supporting structure of the dome, Chen Xin deliberately

chose light materials, and even the outer layer of the dome was made of EFTE

airbags and light insulation materials instead of heavy materials such as

glass.

These lightweight materials greatly reduce the self-weight of the dome itself,

while maintaining sufficient structural strength. With the addition of some

designs later added by Chen Xinxin, the Dome New City shelters an entire city

of hundreds of thousands of people. Dome.

However, the use of this part of the material is also the largest part of the

construction cost of the dome city.

These materials themselves were relatively high-cost materials even before the

disaster, but at that time, there was enough industrial scale to be mass-

produced, and it was natural to suppress the cost 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 has to support

both Europe and the Middle East, so there are not many resources that can be

squeezed out.

If the cost cannot be reduced, the country can only afford the construction of

a dome city with the current affordability of the country, and it is even a

little tight.

However, if these materials are replaced with cheaper materials, it will also

affect the weight and structure of the dome. If you want to do this, you must

overthrow the original design, which is equivalent to overturning everything.

Even for Chen Xin, this is not something that can be done easily.

However, he still convened relevant researchers to study the issues in this

regard. UU read www.uukanshu.com to see how to meet the requirements raised by

the senior management.

The first thing that was raised was the construction problem. Some people

think that the current 3D printing technology can be used for the construction

of the dome city. After all, this printing technology is not only convenient,

but also saves labor investment.

Chen Xin quickly adopted this suggestion, and designed a new type of 3D

printing equipment that can be used for the construction of the dome. As long

as the materials are available, the supporting structure of the dome can be

printed directly.

But this is still not enough. Although this has indeed effectively reduced

some construction costs, it still does not meet the standards required by

high-levels.

If you want to really reduce the cost, you still have to make a fuss about the

materials.

Faced with this problem, the researchers who were called by Chen Xin proposed

two diametrically opposite proposals.

One party hopes to be able to develop new materials. As long as they can

develop materials that also meet the construction requirements and at the same

time, the high-level requirements can be achieved.

On the other hand, I hope to work ** the structure. By optimizing the

structure, replacing the relatively expensive materials with cheap materials

can also meet the requirements of high-rise buildings.
