by 2022 is the first year of the phased work goal of precast buildings in the 14th five year plan and the “second half” of the 10-year plan for the vigorous development of precast buildings at the national level.
From the perspective of local policy actions last year, local governments continue to increase their support for the development of precast buildings.
Yunnan, Sichuan, Heilongjiang and other places have successively issued policies on “further promoting the development of precast buildings” to clarify the development objectives for some time in the future.
Chongqing, Guangdong, Beijing, Jiangxi and other places have launched a number of local standards.
All localities have issued policies to increase support for precast buildings.
1 Department of housing and urban rural development of Yunnan Province: encourage and guide the use of precast construction methods.
First, adhere to classified promotion.
Focus on the promotion of steel structure in public buildings and steadily improve the scale of cast steel structure buildings; Promote concrete structure in residential buildings and increase the proportion of precast concrete buildings; Explore the national, regional and cultural characteristics of precast wood structure architecture; In the fields of municipal administration, tourism, health, emergency support, etc., promote the application of box cabin and other integrated precast buildings.
Second, encourage the use of assembly technology system.
For concrete buildings that adopt precast technology system and reach a certain assembly rate, local competent departments of housing and urban rural construction can support them in accordance with laws and regulations.
We will increase and implement policy support for precast buildings in finance, taxation, finance, land and technology.
To create a good atmosphere, we should further strengthen publicity and enhance the public’s cognition, understanding and recognition of precast buildings.
2.
Sichuan Provincial Department of housing and urban rural development: define the five-year development goal of precast buildings, new precast buildings account for 40% of new buildings, and the assembly rate of single buildings of precast buildings shall not be less than 50%; Basically form a market supply system with unified standards for main components, parts and components.
In terms of specific tasks, projects invested or led by government funds are required to take the lead in promoting precast construction technology, and social investment projects should also accelerate the promotion and use.
In addition, the plan also proposes to guide enterprises to give full play to the advantages of overall design and construction of EPC, and cultivate 10 leading EPC enterprises with the ability to integrate the whole industrial chain of precast construction.
3.
Anhui Provincial Department of housing and urban rural development: it is planned that by 2025, the production capacity of precast construction enterprises will reach 50 million square meters.
In June 2021, Anhui Provincial Department of housing and urban rural development solicited opinions on the 14th five year plan for the development of precast buildings in Anhui Province.
According to the draft, Anhui’s goal is to cultivate or introduce no less than 5 integrated design and construction enterprises by 2025, And form a precast construction enterprise integrating design, production and construction, with a production capacity of 50 million square meters, and precast buildings account for 30% of the new construction area; Cultivate more than 50 provincial precast construction industrial bases and 3 ~ 5 national precast construction industrial parks.
4.
Heilongjiang Department of housing and urban rural development: strive to make the precast buildings in the whole province account for 30% of the newly-built building area in cities and towns.
First, clarify the overall task and objectives, pay attention to the cultivation of the precast construction industrial base, and strive to build 1-2 “provincial precast industrial bases” by the end of 2025.
The development environment, market mechanism and service system of precast buildings have been basically formed, and the technical system is basically complete, The management system is relatively perfect, the talent team cultivation mechanism is basically established, and the application of key technologies and complete sets of technologies is gradually mature, so as to strive to make the proportion of precast buildings in the city’s new urban construction area reach 30% at the end of the 14th Five Year Plan period; Second, establish a reward and incentive mechanism, put forward measures such as plot ratio reward, pre-sale conditions of commercial housing, financial reward, innovative implementation of provincial support policies, and do a good job in the implementation and promotion.
Many provinces have issued local standards to clarify the technical requirements of precast buildings.
In addition to formulating phased development objectives of precast buildings, all parts of the country have also refined the relevant policies of precast buildings, including strict implementation of requirements, clarification of technical problems, introduction of local standards, etc.
Chongqing Municipal Commission of housing and urban rural development: several detailed rules for the calculation of precast buildings were updated.
In January 2021, Chongqing Municipal Commission of housing and urban rural development clarified some technical problems of precast buildings, including the maximum applicable height of precast concrete buildings, the requirements for the application scope of precast floors, the selection of high-precision formwork technology, the identification of precast floors, etc, And the detailed rules for calculating the assembly rate of local precast buildings.
In April of the same year, the notice on strictly implementing the implementation requirements of precast buildings was issued, which proposed to ensure that the relevant provisions shall be strictly implemented for the social investment projects in which the implementation requirements of precast buildings have been clarified in the government invested construction projects and land transfer links; Government investment projects that fail to meet the implementation requirements of assembled buildings shall not pass the preliminary design approval; If the implementation requirements of the assembled building are not fulfilled as required, the examination institution shall not issue the construction drawing examination certificate; The enterprise shall not change the qualified construction drawing design documents without authorization.
In addition, Guangdong, Beijing, Jiangxi and other places have issued a number of local standards.
In March 2021, Guangdong Provincial Department of housing and urban rural development issued the technical standard for durability of precast building concrete structures.
In June 2021, Beijing also launched 22 local standards such as evaluation standard for precast buildings and technical specification for precast pavement on construction site; Jiangxi Provincial Department of housing and urban rural development approved and issued the production technical standard for precast concrete components of precast buildings and the evaluation standard for precast buildings.
Green and low-carbon development is the only way for China’s construction industry.
With the promotion of precast buildings, it is believed that precast buildings will also usher in a golden period of vigorous development in the next 10 years..
