Comprehensively promote precast buildings
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 and environment in our province and the exploration of 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.
The targeted technology and standard system will promote the reform of the implementation mode of engineering organization, continue to promote the industrialization, digitalization and intelligent upgrading of construction, improve the quality, safety, benefit and quality of the project, and realize the transformation, upgrading and sustainable and healthy development of the construction industry.
Timely release the promotion projects and catalogue of applicable technologies for precast buildings.
Since the provincial government issued the implementation opinions on vigorously developing precast buildings (qiongfu [2017] No.
In 2022, newly constructed precast buildings will account for 60% of new buildings; Since then, it has increased year by year.
Actively cultivate upstream and downstream industrial clusters based on the construction industry, basically form a precast construction industry chain covering R & D and design, component production, construction and installation, training and education, and greatly improve the level of building industrialization, digitalization, intelligence and low-carbon.
(leading unit: governments of all cities and counties; cooperating unit: Provincial Development and Reform Commission and Provincial Department of housing and urban rural development) (VI) carry out project pilot demonstration.
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.
Promote the expansion and application of precast construction technology from housing construction engineering to municipal engineering.
By 2025, the proportion of newly started precast buildings in new buildings will be more than 80%.
（2） Work objective the modernization level of the construction industry has been significantly improved.
Popularize the use of precast reinforced concrete inspection wells, integrated drainage kerbs, ground pavement components, Lane slabs, crash walls, segment components and other industrialized production of finalized, standardized and integrated precast components.
Vigorously promote the precast interior decoration, realize the demonstration and application of the precast interior decoration, and promote the comprehensive expansion of the precast construction mode from the main structure to the enclosure structure, interior decoration and equipment pipelines.
A standard system for precast buildings covering design, production, construction, inspection and acceptance is gradually established to support the high-quality green development of precast buildings.
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, achieve low-carbon green development, and boost the construction of Hainan Ecological Civilization pilot zone, the following opinions are put forward.
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.
(the Provincial Department of housing and urban rural development, the provincial market supervision bureau, and the municipal and county governments are responsible for the division of responsibilities) (V) expand the application of components in municipal engineering, and promote the expanded application of precast construction technology from residential buildings, public buildings, and industrial buildings to municipal infrastructure.
Study and formulate product quality standards for precast components.
Among the projects invested by the government, especially those invested by the government or society in the key parks of Hainan free trade port, select qualified projects to carry out the integrated demonstration of precast buildings, green buildings, ultra-low energy consumption buildings and other green and low-carbon technologies in tropical areas, Research and promote the integrated application of precast buildings and solar energy..
For the urban roads, bridges, tunnels, rail transit, comprehensive pipe gallery, landscaping, environmental sanitation and other projects invested and constructed by the government, if the conditions are met, the development and reform department shall clearly adopt the cast components when approving the project initiation.
All new buildings that meet the conditions shall be constructed in a cast manner.
Strictly implement the system of household acceptance and model room for full decoration.
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.
Actively promote steel structures and steel-concrete composite structures in municipal bridges, rail transit, transportation hubs, bus stops, public parking buildings, airport terminals and other transportation infrastructure.
100) in 2017, our province has vigorously promoted the development of precast buildings, and the precast building area has shown a significant growth trend, doubling year by year for four consecutive years.
At the same time, there are still some problems such as weak foundation of the construction industry, less mature technical system, low degree of standardization, low overall level of talents and capabilities, 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.
(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.
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, storage system, and gradually form a standardized, serialized and universal supply system of high-quality decoration parts and components.
Take the lead in adopting precast interior decoration in government funded affordable housing projects such as comfortable housing, and promote precast decoration components.
Annex several opinions on further promoting the high-quality green development of precast buildings in our province (Exposure Draft) the development of precast buildings is a major change in the construction mode.
