分类:industry-forum News 763

On August 11, the Beijing Municipal Commission of housing and urban rural development issued the implementation opinions on the further development of prefabricated buildings (Draft for comments). The purpose is to further promote the development of prefabricated buildings in Beijing, implement the industrialization of new buildings, improve the construction level and construction quality, and drive the transformation and upgrading of the construction industry. The following opinions are put forward.



The exposure draft points out that by 2022, Beijing will realize that prefabricated buildings will account for more than 40% of the new building area, and by 2025, prefabricated buildings will account for 55% of the new buildings.

The draft also pointed out that affordable housing and commercial housing development projects with state-owned land use rights obtained by bidding, auction and listing should meet the standard of assembly rate of no less than 60%; The newly approved new buildings invested by the government, new public buildings, industrial buildings and other buildings within the scope of implementation shall meet the standard that the assembly rate shall not be less than 50%.

In terms of key work, the draft also gives relevant guidance and suggestions: give play to centralized scientific and technological support, strengthen systematic integrated design, improve standardized production level, promote lean construction, implement full decoration finished product delivery, improve information application level, innovate project organization and management mode, carry out evaluation demonstration and reward, and cultivate professional talent team.

The draft mentioned that it is necessary to support the R & D of prefabricated buildings and strengthen the R & D and application of new structural system, standardized design, quality inspection and efficient connection technology of prefabricated buildings. A database of major scientific and technological achievements of prefabricated buildings has been preliminarily established. Further improve the technical standard system, evaluation system and pricing basis of prefabricated buildings.

In addition, new buildings should implement the delivery of fully decorated finished products, gradually improve the application proportion of prefabricated decoration in indemnificatory housing, commercial housing and public buildings, and encourage the decoration and transformation of existing buildings to adopt prefabricated decoration.

Vigorously promote the application of building information model (BIM) technology in the whole life cycle of design, production, construction, operation and maintenance. The prefabricated construction projects invested by the government and public rental housing should apply BIM Technology in the whole life cycle, and other types of prefabricated construction projects are encouraged to apply BIM Technology in the whole life cycle.

Explore the establishment of an Internet platform for the construction industry, carry out intelligent upgrading of production equipment and construction equipment, encourage the application of intelligent equipment such as construction robots, industrial robots and intelligent mobile terminals, and promote intelligent office and building automation systems. Promote the integrated application of big data technology, 5g, radio frequency identification (RFID) and two-dimensional code identification in the construction and management of prefabricated buildings.

In the process of developing prefabricated buildings, on the one hand, real estate enterprises are actively layout. Vanke began to develop prefabricated buildings in 2003 and established Vanke Industrialization Center, which is committed to the research of prefabricated system. Since 2007, it has gradually promoted prefabricated buildings throughout the country and established Vanke prefabricated system.

At present, country garden has established a highly standardized parts library, house type library and building type library to open up the data flow of the whole industrial chain such as R & D, design, production, transportation and construction with the help of BIM Technology. Mass customization of PC components is realized through the automatic production line, and construction robots and intelligent construction equipment are applied on the construction site to reduce the waste of construction materials, improve the construction quality, and achieve green consumption reduction in the whole construction process.

In addition, real estate enterprises regard prefabricated construction as the key business of enterprise development in the future. Meihao real estate officially entered the field of prefabricated buildings in 2017 and announced the transformation from traditional real estate development to intelligent building integration business of integrated prefabricated buildings. According to the annual report, in terms of prefabricated construction business, Meihao real estate put into operation two factories in Wuhan Jiangxia factory and Qingdao Jimo factory in 2018, five factories in Henan Xinxiang, Hubei Jingzhou, Hefei Feidong, Chongqing Jiangjin and Changsha Miluo in 2019, and two factories in Chengdu Jintang and Jiangsu Yizheng in 2020. In 2020, the fabricated construction business of Meimei real estate involved a total amount of 4.765 billion yuan.

Capital is also laying out prefabricated construction innovation companies. On July 28, the digital technology integration platform company of prefabricated buildings, Dale decoration, announced the completion of strategic financing, and achieved component standardization based on AI prefabricated building design, so as to reduce costs and improve efficiency for customers and suppliers. Investors include star institutions such as Tencent and China Merchants.

On August 10, the assembly interior decoration company Weishi housing workers announced that it had completed a new round of financing of tens of millions of yuan, with the exclusive strategic investment of Panasonic electric.

Information shows that since 2014, China has successively issued a number of important policy documents to promote the development of prefabricated buildings. Among them, the action plan for prefabricated buildings in the 13th five year plan: by 2020, the proportion of prefabricated buildings in new buildings will reach more than 15%, of which the key promotion areas, active promotion areas and encouraged promotion areas will be more than 20%, 15% and 10% respectively; The opinions on promoting the sustainable and healthy development of the construction industry issued by the State Council office requires that by 2025, the proportion of prefabricated buildings in new buildings should reach 30%.

According to the data of prospective industry research institute, in 2020, the proportion of prefabricated buildings in the new construction area will reach 15%, 30% in 2025, and about 14% in 2018, so it will increase by an average of 2 percentage points per year in the future.

The data also shows that according to the reference basis of prefabricated construction cost issued by the Ministry of housing and urban rural development, based on 2230 yuan / m2 (considering the different effects of rising technology level and rising prices on the price level, assuming that the cost will remain unchanged in the next few years), the area of new real estate buildings will replace the area of new urban buildings, By 2024, the scale of China’s prefabricated construction market will reach more than 120 billion yuan.

At present, according to the guidance issued by Beijing, the development requirements and speed of prefabricated buildings are improving rapidly, and the trillion market may come quickly in the future.
