Hainan Daily: the primary task of prefabricated building is to raise the production capacity of components


However, the components of industrial production and the prefabricated construction method can form a standardized system, and the dependence on labor is not high, which can fundamentally solve the common quality problems of traditional buildings, such as cracks and water seepage, and improve the building quality

.

I believe that through attracting investment this year, Hainan will be able to improve the production capacity of prefabricated building The production capacity of matching building components will be greatly improved

.

In terms of the production of prefabricated building components, the Xinzhu green building industrial base in Ding’an County has a planned area of 3348 mu, with a total investment of 265 million yuan in two existing projects

.

The two projects are expected to have an annual output value of more than 1.2 billion yuan after they are completed

.

Now there are 14 manufacturers of prefabricated building in the whole province, but the production capacity is still not enough

.

In terms of construction period, most of the components of prefabricated buildings are completed in the factory, water and electricity installation and main body installation can be carried out simultaneously, and the overall delivery period is about 30% less than that of traditional buildings; in terms of energy conservation and environmental protection, traditional building materials are wasted seriously, resulting in a large amount of dust, noise, construction waste, etc

.

Therefore, Hainan’s construction enterprises should do two things: first, they should strengthen the cultivation of talents

.

According to statistics, since 2018, there have been 156 construction projects in Dingan County, 22 of which should be constructed by prefabricated construction according to policy requirements, and 25 of which have been constructed by prefabricated construction

.

Wu Yachun said that in terms of government support and guidance for the development of prefabricated buildings, Hainan Province has launched “13 measures for prefabricated buildings” to solve the problems restricting the development of prefabricated building market from the aspects of capacity layout, scientific and technological innovation guidance, plot ratio reward, supervision and accountability

.

According to the work report of Hainan provincial government, prefabricated buildings will be fully implemented during the 14th Five Year Plan period to accelerate the development of tropical building materials industry cluster

.

The development of the industry is inseparable from talents, and they must have enough talent reserves

.

The development of prefabricated buildings is a great opportunity to improve the construction quality, improve the local construction technology system, and promote the transformation and upgrading of Hainan construction industry

.

In strict accordance with the decision-making and deployment of Hainan provincial Party committee and government, Ding’an actively responds to the requirements of modern development of construction industry, and speeds up the promotion of prefabricated buildings in terms of system and mechanism construction, market cultivation and industrial chain development

.

During the 13th Five Year Plan period, the annual built-up area of prefabricated buildings in Hainan has increased year by year, and the built-up area will exceed 10 million square meters in 2020

.

During the “14th five year plan” period, prefabricated buildings were fully implemented, which shows Hainan’s determination to develop green buildings represented by prefabricated buildings and adhere to the protection of excellent ecological environment

.

Universities and enterprises should increase research and development efforts, and improve the prefabricated building technical system in Hainan from the perspective of design, production and construction according to the climate characteristics of Hainan

.

Last year, the area of prefabricated construction projects reached 11 million square meters

.

According to the requirements of this year’s government work report, it is estimated that this year’s prefabricated construction area will reach 17 million square meters

.

He Jingping said that Wanning City also listed in the overall land use planning and urban master planning that in the total land supply area of construction land in the city, a certain proportion of prefabricated buildings should be implemented, and the number should be increased year by year, so as to effectively promote the construction of new commercial residential projects with a total construction area of more than 100000 square meters invested by the society

.

However, with the rising labor cost, the construction cost of prefabricated buildings is much higher than that of traditional buildings, and the later operation and maintenance cost is lower

.

Prefabricated buildings meet the requirements of high quality development in Hainan Province

.

For commercial housing projects built in the form of prefabricated buildings that meet the national recognition standards for prefabricated buildings, the construction area will be awarded according to the proportion of 3% of the building area that meets the requirements of prefabricated buildings, and the awarded building area will not be included in the plot ratio accounting

.

in the construction process, while the prefabricated construction site is mainly dry operation, which can be used for construction It can effectively reduce energy consumption and environmental pollution; in terms of construction cost, the construction cost of prefabricated buildings is higher than that of traditional buildings due to imperfect industrial supporting facilities and immature related technologies

.

On January 13, four projects of Lingao Golden Port Industrial Park have been started at the same time

.

Among them, the investment in Ding’an new century construction industry project is 206 million yuan, which is expected to start trial production and operation in April 2021; the total investment in green building integrated technology project is 59.35 million yuan, which is planned to start trial production in July 2021

.

Therefore, from the perspective of the whole life cycle of buildings, the construction cost of prefabricated buildings is higher than that of traditional buildings The matching building has a greater cost advantage

.

Wu Yachun believes that prefabricated buildings have the advantages of high degree of industrialization, short construction period, convenient transportation of components and parts, and green environmental protection, which are in line with the development requirements of Hainan province’s strategy of building a national ecological civilization experimental zone

.

These policies have played a very positive role in supporting and guiding the development of prefabricated buildings, but the government and enterprises can still make efforts in cultivating talents and guiding the development of the industry, such as establishing the evaluation mechanism of Engineering titles of prefabricated buildings and the training mechanism of industrial workers

.

To promote the transformation and upgrading of Hainan construction industry, Huo Juran said that during the 13th Five Year Plan period, the promotion of prefabricated buildings in Hainan Province has achieved leapfrog development

.

Wu Yachun cites a specific case: for example, in the construction of a 30 story residential project with prefabricated prefabrication rate of 35%, the PC prefabricated building can save 20% to 35% of the construction period, reduce 20% to 40% of the energy consumption, and reduce 60% to 75% of the on-site construction personnel and 20% to 30% of the construction dust

.

He Jingping said that Wanning City began to promote prefabricated construction from the public building projects invested by the government, and stipulated that for the projects with prefabricated technology in the city, Wanning City would refer to the construction application process of key projects and include them in the green channel of project approval

.

In this regard, Hainan’s universities have more advantages, and they should cultivate talents through school enterprise cooperation; second, they should further improve the construction technology system, and Hainan’s construction enterprises should have more talents The development of prefabricated building is relatively late, the building foundation is relatively weak, and the relevant technical system is not perfect

.

Wanning City has also formulated the detailed rules for the implementation of the plot ratio Award for prefabricated commercial housing projects

.

Huo Juran introduced that at present, the primary task of Hainan prefabricated building is to improve the production capacity of components

.

“Expand and strengthen the green building industry base in Hsinchu, and promote the prefabricated construction industry to become a new economic growth pole.” Liu Fengsong said

.

In recent years, with the gradual deepening of the research on prefabricated building technology, the increase of labor costs and the increasing call for the promotion of green building, the advantages of prefabricated building gradually appear, and will be widely used in civil and industrial buildings

.

According to Liu Fengsong, Ding’an attaches great importance to the promotion of prefabricated buildings

.

At this year’s two sessions of Hainan Province, Huo Juran, who was present as nonvoting delegates and director of Hainan Provincial Department of housing and urban rural development, Liu Fengsong, deputy to the provincial people’s Congress and Secretary of Ding’an County Party committee, he Jingping, deputy to the provincial people’s Congress and Secretary of Wanning municipal Party committee, Wu Yachun, who was present as nonvoting delegates, Secretary of the Party committee and chairman of Hainan Construction Group Co., Ltd., were interviewed by Hainan Daily to interpret the promotion of prefabricated construction from different perspectives How can green buildings, represented by buildings, enable Hainan to develop with high quality

.

Wu Yachun believes that enterprises are the main force in promoting the development of prefabricated buildings

.

“I think the development of prefabricated buildings in Hainan has entered a” fast lane “.

.

Wu Yachun believes that the development foundation of Hainan construction industry is weak, and the foundation is relatively weak

.

Why do we say that the promotion of prefabricated buildings in Hainan is closely related to adhering to the excellent ecological environment? “Compared with traditional buildings, prefabricated buildings have incomparable advantages in building quality, construction period, energy conservation and environmental protection.” Wu Yachun introduced that in terms of building quality, the traditional construction method has a high dependence on labor, and it is difficult to control the quality

.

Prefabricated building market has development potential, many cities and counties are also optimistic about the development of prefabricated building, accelerate the promotion of prefabricated building and industrial landing
