Promote the application of intelligent production lines for steel structural members and precast concrete structural members, promote the realization of information management in production, and gradually establish a professional, large-scale and information-based production system based on standard parts and components..

II.

Move forward in the direction of intelligence, effectively improve the industrialization level of new buildings represented by precast buildings, and accelerate the transformation and upgrading of the construction industry.

Improve the standardization level of precast components, promote the use of size guidelines for main components, parts and components, and improve the basic size and combined size library of precast components to meet the requirements of standardized design and selection.

（4） The project whose implementation standard adopts precast buildings shall comply with the relevant national and municipal standards, and its assembly rate shall meet the requirements of the evaluation standard for precast buildings (DB11 / t1831).

Further improve the technical standard system, evaluation system and pricing basis of precast buildings, study and formulate the standardized Atlas of precast buildings, and regularly publish the catalogue and guide for the promotion of applicable technologies of precast buildings.

16 District People’s governments, municipal government committees, offices and bureaus, and municipal institutions: in order to implement the opinions of the general office of the CPC Central Committee and the general office of the State Council on promoting green development of urban and rural construction and the guiding opinions of the General Office of the State Council on vigorously developing precast buildings (Guo Ban Fa [2016] No.

Improve the design and selection standards, implement the standardized design of building plane, facade, components, parts and interfaces, and promote the design method of less specifications and more combinations to ensure that the design depth meets the production and construction requirements.

Precast buildings shall be adopted for commercial housing development projects, new public construction projects with a floor area of more than 20000 square meters, and new plants and warehouses on industrial land.

　　2.

The newly-built indemnificatory housing projects with an aboveground construction area of more than 20000 square meters (including public rental housing, common property right housing and resettlement housing, the same below) shall adopt precast buildings.

Recently, Beijing issued a notice on the implementation opinions on the further development of precast buildings, which made it clear that by 2025, precast buildings will account for 55% of the new construction area.

　　2.

（7） Implement standardized production, actively promote the rational layout of precast building components and parts manufacturers in Beijing, Tianjin and Hebei, and regularly release the supply and demand of production capacity.

Key work (V) strengthen the support of scientific and technological innovation, support the scientific and technological breakthrough of precast buildings, and establish a database of major scientific and technological achievements of precast buildings.

In the context of the transformation and upgrading of the construction industry, the central and local governments have continuously issued relevant policies to promote the development of the precast construction industry.

The assembly rate of each single building shall not be less than 50% for new buildings with an above ground construction area of more than 3000 square meters, new public construction projects with an above ground construction area of more than 20000 square meters, and new plants and warehouses on industrial land invested by the government.

For newly-built affordable housing projects and commercial housing development projects with a construction area of more than 20000 square meters, the assembly rate of each single building shall not be less than 60%.

Within the above implementation scope, the structures and supporting auxiliary facilities (garbage room, power distribution room, etc.) separately constructed in the project may not adopt precast buildings.

Strengthen the R & D and application of new structural system, quality inspection technology and efficient connection technology of precast buildings, tackle the integration technology of sustainable and high-quality precast building design and construction, accelerate the integration and demonstration application of technologies such as precast buildings, green buildings and ultra-low energy consumption buildings, study the integrated application of precast buildings and photovoltaic technology, and study the application of precast building technology in urban renewal.

（2） The work goal is to achieve that the proportion of precast buildings in the newly-built building area will reach 55% by 2025, and basically build a modern building industry system characterized by standardized design, industrialized production, assembled construction, integrated decoration, information management and intelligent application; The industrialization of new buildings will drive the design, construction and parts manufacturing enterprises to improve the level of innovation and development, and cultivate a number of general contracting enterprises with intelligent construction ability and corresponding professional high-level skilled teams.

Jing Zheng Ban Fa [2022] No.

Actively promote the demonstration application of steel structure housing, and carry out the pilot work, promotion and application of steel structure rural housing.

The development of precast buildings puts forward new requirements for the future development of the interior design industry.

（3） Scope of implementation 1 The newly approved government invested new buildings with an aboveground building area of more than 3000 square meters shall adopt cast buildings, of which the new public buildings with a single aboveground building area of more than 10000 square meters shall adopt steel structure buildings.

Coordinate the building structure, electromechanical equipment, parts and components, assembly construction and decoration, and implement integrated forward design and standardized design.

71), further promote the development of precast buildings and improve the construction level and quality, With the consent of the municipal government, the following implementation opinions are put forward.

Improve the technical scheme planning and design scheme technical demonstration system in the early stage of the project.

（6） Strengthen systematic and integrated design, give play to the leading role of design, implement the architect responsibility system, implement the whole process engineering consultation dominated by design, and promote the coordination of the whole industrial chain.

　　1.

Interior designers should combine the changes of the industry and understand the needs of the industry in order to meet the new challenges brought by the development of precast buildings.

Relevant requirements shall be set by means of bidding, auction and hanging documents.
