Encourage research and development, improve the product supporting capacity of integrated parts and components such as integrated bathroom, integrated toilet, drainage on the same floor, integrated kitchen, integrated partition and wall system, integrated floor system, integrated door and window system and storage system, and gradually form a standardized, serialized and universal supply system of high-quality decoration parts and components.

In 2022, newly constructed precast buildings accounted for 60% of new buildings; Since then, it has increased year by year.

Promote the expansion and application of precast construction technology from housing construction engineering to municipal engineering.

(leading unit: Provincial Department of housing and urban rural development; cooperating units: provincial market supervision bureau and Provincial Department of industry and information technology) (IV) vigorously promote precast interior decoration and formulate technical guidelines and pricing basis for precast interior decoration.

Since the provincial government issued the implementation opinions on vigorously developing precast buildings (qiongfu [2017] No.

Strictly implement the system of household acceptance of full decoration and model room.

At the same time, there are still some problems such as weak foundation of construction industry, less mature technical system, low degree of standardization and low overall level of talents and capabilities.

The market supervision department should change the supervision mode and method, adapt to the laws and characteristics of precast decoration, and strengthen the supervision and management of the quality of precast parts.

Vigorously promote the precast interior decoration, realize the precast interior decoration from demonstration application to what should be done, and promote the comprehensive expansion of the precast construction mode from the main structure to the enclosure structure, interior decoration and equipment pipeline.

By 2025, the proportion of newly started precast buildings in new buildings will be more than 80%.

Actively cultivate upstream and downstream industrial clusters based on the construction industry, basically form a precast construction industrial chain covering R & D and design, component production, construction and installation, training and education, and greatly improve the level of construction industrialization, digitization, intelligence and low-carbon.

The comprehensive advantages of precast buildings have not been truly reflected, and the precast buildings in our province are still in the initial stage of development.

(the Provincial Department of housing and urban rural development, the provincial market supervision bureau and the municipal and county governments are responsible according to the division of responsibilities) (V) expand the application of parts and components in municipal engineering, and promote the expansion and application of precast construction technology from residential buildings, public buildings and industrial buildings to municipal infrastructure.

In order to further promote the high-quality development of precast buildings in our province, improve the construction level and construction quality, drive the transformation and upgrading of the construction industry, realize low-carbon green development, and boost the construction of Hainan Ecological Civilization pilot area, our office drafted several opinions on further promoting the high-quality green development of precast buildings in our province (Draft for comments), which is now open to the public for comments.

Relevant units and people from all walks of life can send their opinions to kcsjykjc by email before March 3, 2022_ szjt@hainan.gov.cn 。 It is hereby announced.

Study and formulate product quality standards for precast components.

Cast in Sockets

Gradually establish a standard system of precast buildings suitable for the actual situation of our province, covering design, production, construction, testing and acceptance, so as to support the high-quality and green development of precast buildings.

100) in 2017, our province has vigorously promoted the development of precast buildings, and the area of precast buildings has shown a significant growth trend, doubling year by year for four consecutive years.

Annex: Several Opinions on further promoting the high-quality green development of precast buildings in Hainan Province (Exposure Draft) Hainan Provincial Department of housing and urban rural development February 25, 2022 (this initiative was made public) Annex several opinions on further promoting the high-quality green development of precast buildings in Hainan Province (Exposure Draft) the development of precast buildings is a major change in the construction mode.

Take the lead in adopting precast interior decoration in affordable housing projects such as affordable housing invested by the government, and promote precast decoration parts.

*** Vigorously develop new-type building industrialization focusing on precast buildings, gradually form a suitable and targeted technology and standard system in Hainan, promote the reform of engineering organization and implementation mode, continue to promote building industrialization, digitization and intelligent upgrading, improve project quality, safety, efficiency and quality, and realize the transformation, upgrading and sustainable and healthy development of the construction industry.

Promote the application of precast interior decoration in the project, and guide the project to adopt complete sets of precast decoration technologies such as dry construction method floor, dry construction method partition wall and wall, integrated kitchen, integrated toilet and pipeline separation.

Timely release the promotion projects and catalogue of applicable technologies for precast buildings.

All qualified new buildings are built in the assembly mode.

In order to further promote the high-quality development of precast buildings in our province, improve the construction level and quality, drive the transformation and upgrading of the construction industry, realize low-carbon green development, and boost the construction of Hainan Ecological Civilization Experimental Zone, the following opinions are put forward.

（2） Work objectives: the modernization level of the construction industry has been significantly improved.

For the urban roads, bridges, tunnels, rail transit, comprehensive pipe gallery, landscaping, sanitation and other projects invested and constructed by the government, if the conditions are met, the development and reform department shall clearly adopt the construction of cast parts when approving the project initiation..

2、 Key work (3) establish and improve the technical standard system, and gradually improve the evaluation standard of precast buildings in our province in combination with the characteristics of climate environment and engineering practice; Actively promote the application of the mature precast building technology system of precast interior decoration and vertical precast components in our province, and improve the assembly rate of new buildings.

At present, under the major strategic background of carbon peak and carbon neutralization, it is very urgent to promote precast buildings at a higher level around the concept of green development of urban and rural construction.
