Review on the development of prefabricated building demonstration city II


In 2016, the general office of the State Council issued the “guidance on vigorously developing prefabricated buildings” and proposed to strive to make prefabricated buildings account for 30% of the new building area in about 10 years

.

The pace of the first tier cities can be a little faster, while other cities can make plans steadily according to the actual situation; some places are rich in steel resources and wood resources, so they can focus on the development of prefabricated steel structure or wood structure buildings

.

Prefabricated building involves different industries and industrial chain enterprises

.

The prefabricated construction industry cluster needs further development

.

However, in order to further reduce costs and give full play to the advantages of prefabricated buildings, the establishment and improvement of relevant technical standards are urgent

.

They also have the ability to drive the development of the upstream and downstream industrial chain

.

The initiative and strength of promoting prefabricated buildings are not enough

.

The early development of prefabricated building mainly depends on the promotion of policy, but in the long run, it still needs the real recognition of the market

.

Different industries and enterprises of different levels need further collaborative development

.

Although it is not completely accurate, it is also conducive to the understanding of non professionals

.

In the future, the demonstration cities need to continue to strengthen publicity through organizing policy publicity, technical training and outdoor publicity activities, so as to let more enterprises and the public understand the advantages of prefabricated buildings, correctly treat the difficulties encountered in the current promotion, and form a good promotion atmosphere

.

Some people compare prefabricated building to “building a house like a car”

.

In recent years, a large number of practices in the first batch of 30 prefabricated building demonstration cities in China have proved that prefabricated buildings have the advantages of quality and efficiency over the traditional construction mode

.

High cost is the pain point of large-scale promotion of prefabricated buildings

.

At the same time, we should strengthen systematic policy support in many aspects, such as financial incentives, the implementation of taxes and fees, financial services, and industry incentives

.

The original intention of prefabricated building is to coordinate the building structure, mechanical and electrical equipment, parts, assembly construction, decoration, and promote the integrated design

.

Pay attention to cultivate and serve the leading enterprises of prefabricated construction, and build the brand matrix

.

The leading enterprises have strong strength and are willing to explore the transformation and upgrading of the construction industry

.

At the same time, they should try every means to do a good job for these enterprises and be willing to serve the “shop boy” of the enterprises

.

According to local conditions, explore the development mode of prefabricated buildings in line with the characteristics of the city

.

After the exploration and practice during the 13th Five Year Plan period, prefabricated buildings have entered the stage of accelerated development and expansion and quality improvement, and some non demonstration cities are also making efforts one after another

.

In the future, we should better improve the “script” and organize more participants from different fields and different levels to carry out collaborative “performance” so as to promote the development of prefabricated building industry‚Äú The interaction between “actor” and “audience” is better, which makes the prefabricated building truly “high quality and low price”

.

At present, due to the lack of standardized design, prefabricated buildings have many components of different sizes and large amount of molds, which not only affects the production efficiency, but also increases a lot of production costs to a certain extent

.

There is still a big gap between integrated design and construction

.

Assembly building demonstration city (example city) and industrial base practice case collection to promote the new building industrialization represented by assembly building, and walk out a new building industrialization road with high technology content, good economic benefits, low resource consumption, less environmental pollution, and full play of human resource advantages, which is to solve the problem that China’s construction industry has been large but not strong for a long time Weak foundation, low level of industrial chain coordination, fragmentation of industrial organization, extensive and backward construction methods are the inevitable choice..

.

After several years of vigorous promotion, the first batch of 30 prefabricated building demonstration cities in China have achieved good results in the field of prefabricated building

.

The development of prefabricated building is not only an important measure for China’s construction industry to catch up with the world’s advanced construction level, but also an urgent need for the industry’s own green development, and an important way to meet the public’s access to high-quality buildings

.

The development of prefabricated buildings should be adapted to local conditions, according to the city’s own resource endowment, from the reality, not “one size fits all”

.

At present, although housing is closely related to our life, the popularization rate of prefabricated building related knowledge among ordinary consumers is still very low, and even many people have not heard of the word “prefabricated building”, let alone understand its advantages and future development trend, which is obviously not conducive to the promotion of prefabricated building

.

In order to promote its sustainable development, it is necessary to develop industrial clusters and build a benign industrial ecosystem

.

The proportion of newly-built prefabricated buildings in the total construction area of some cities has exceeded the expected goal, but the bottleneck problem hindering the faster and better development of prefabricated buildings is still unclear There are many

.

Further innovation and improvement of prefabricated building technology standard system

.

Next, the demonstration cities should start from building a modern production system, improving the supervision and service system, strengthening the application of advanced technology, strengthening the promotion of scientific and technological innovation and other aspects, adapt to the new requirements of the development of prefabricated buildings, and timely adjust some implementation methods that do not adapt to the new situation

.

Through the promotion of universal, modular, and standardized design methods, it actively applies the building information model technology to improve the collaborative design ability of various specialties in the construction field, so as to strengthen the guidance and service for the whole process of prefabricated building construction It’s our business

.

Strengthen publicity and promotion to improve the public awareness level of prefabricated buildings

.

In order to completely change the traditional cast-in-place mode and promote prefabricated buildings on a large scale, we should not only rely on the promotion of government departments, but also reduce the cost, so that the majority of enterprises and the public can truly accept

.

Judging from the development of the first batch of 30 prefabricated building demonstration cities in China, the prefabricated building industry in China is characterized by “large stage space, many solo shows, not enthusiastic audience, and poor efficiency of investment companies and performance companies”

.

There is still a long way to go to realize the integrated design and construction

.

According to the time division, the “14th five year plan” period belongs to the “second half” of vigorously developing prefabricated buildings

.

Adjust specific implementation measures in time and strengthen systematic policy support

.

The demonstration cities should focus on cultivating a number of leading enterprises and building brand matrix

.

Although Tangshan City, Handan city and other prefabricated construction demonstration cities have established the prefabricated construction industry alliance, or proposed to promote the formation of prefabricated construction industry chain and industrial cluster
