On further promoting the development of prefabricated buildings


(VI) 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.

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

71), further promote the development of prefabricated buildings and improve the construction level and quality.

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.

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 prefabricated buildings.

II.

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

Promote the certification of green building materials, components and parts, cultivate the integrated supply base of prefabricated building components and parts, and accelerate the construction of green supply chain.

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

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.

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

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 prefabricated buildings.

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

(II) work objective: by 2025, the proportion of prefabricated buildings in the newly-built building area will reach 55%, and a modern building industry system characterized by standardized design, industrialized production, prefabricated construction, integrated decoration, information management and intelligent application will be basically established; 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.

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

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

  1.

(IV) the project adopting prefabricated buildings as the implementation standard shall comply with the relevant national and municipal standards, and its assembly rate shall meet the requirements of the evaluation standard for prefabricated buildings (DB11 / t1831).

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

  2.

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%.

(III) scope of implementation 1 The newly approved government invested new buildings with an aboveground building area of more than 3000 square meters shall adopt fabricated 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.

(VIII) promote lean construction, improve the lean construction organization mode suitable for prefabricated buildings, implement the coordinated construction of the main structure of prefabricated buildings and decoration, enclosure structure and electromechanical equipment, give full play to the advantages of interspersed construction of structure and decoration, and improve the fine management level of the construction site..

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

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 the green development of urban and rural construction and the guiding opinions of the general office of the State Council on vigorously developing prefabricated buildings (GBF [2016] No.

  2.

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.

Prefabricated 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.
