According to the official introduction, at present, there are 24 component production bases in Hainan Province, including 18 concrete precast component production bases, with a design annual production capacity of about 1.57 million m3 / year; There are 6 steel member production bases with a design annual capacity of about 340000 tons / year.
In addition, 6 are under construction and 4 are proposed.
At the same time, due to the use of prefabricated buildings, Hainan Province will reduce the source of construction waste by about 220000 tons in 2020.
Compared with traditional building methods, prefabricated building has many advantages: it will greatly reduce dust, noise and sewage during on-site operation, and can save 80%, 70%, 20%, 70% and 20% of water, materials, time and land, which is very in line with the national energy conservation and emission reduction goal.
At present, Hainan has formulated and issued the responsibility assessment measures for the development objectives of prefabricated buildings in Hainan Province, established a normalized supervision, assessment and evaluation mechanism, and timely informed the annual promotion of prefabricated buildings in cities and counties of the province…
Liu Lianwei, deputy director of Hainan Provincial Department of housing and urban rural development, said in an interview with the media that prefabricated buildings not only meet the development requirements of Hainan’s strategy of building a national ecological civilization pilot area, but also have the advantages of high degree of industrialization, short construction cycle, convenient transportation of components and accessories, recyclable utilization in the whole life cycle, green environmental protection and so on.
“Compared with the concrete structure, the project cost is saved by 10% and the house acquisition rate of the project is increased by 3%.” The reporter learned from the Department of housing and urban rural development of Hainan province that Hainan has continuously improved the top-level design architecture at the provincial level such as supporting policies, standard system, capacity layout and talent team construction of prefabricated buildings since 2018.
In terms of policy, the implementation opinions of the people’s Government of Hainan Province on vigorously developing prefabricated buildings issued in 2017 stipulates the plot ratio incentive policy, which specifies that commercial housing projects built in the prefabricated way will meet the national standards for the identification of prefabricated buildings by the end of 2020, The building area that meets the requirements of prefabricated buildings can be excluded from the floor area ratio accounting according to a certain proportion (no more than 3% of the planned aboveground building area).
According to the development plan for the modernization of construction industry (prefabricated buildings) in Hainan Province (2018-2022), in addition to the existing prefabricated building industrialization bases in Chengmai, Ding’an, Wanning and Sanya, in principle, the new production capacity of prefabricated building components will be centrally distributed to Lingao gold port development zone.
By the end of 2021, the prefabricated building area has exceeded 20 million square meters, which is expected to double year by year for four consecutive years.
The whole steel structure is adopted to save construction period, cost and space.
At present, the proportion of prefabricated buildings in new prefabricated buildings still has great room for improvement.
Beijing, Haikou, December 29 (reporter Wang Ziqian) on December 29, China Railway Construction’s first green building industrial park in Hainan Province was put into operation in jinjinggang Economic Development Zone, Lingao County, Hainan Province.
the products are based in Hainan, facing the Great Bay area of Guangdong, Hong Kong and Macao and radiating Southeast Asia.
In the urban area of Haikou, a twin tower with a height of more than 100 meters uses an all steel structure and climbs rapidly.
Zhang Yu, deputy general manager of China Railway Construction Construction Development (Hainan) Co., Ltd., said that at present, its main business is fabricated PC components.
The industrial park is equipped with 5 internationally advanced prefabricated construction component production lines, with an annual design capacity of 100000 cubic meters.
In the next step, it will focus on the research, development and production of fabricated whole industry chain products, including laminated plates, stairs, shear walls, partitions, balconies, etc.
Combined with the construction of free trade port, Hainan also takes prefabricated buildings as an important measure to promote the transformation and upgrading of the construction industry and one of the important supporting work of carbon peak and carbon neutralization, and lists them as a landmark project for the construction of national ecological civilization pilot zone.
The project area determined to be constructed by assembly in the province in 2018, 2019 and 2020 will be 824.35 million square meters, 435.5 million square meters and 11 million square meters respectively, which has developed rapidly in the past three years with the trend of doubling year by year.
Hainan Province is improving the production capacity layout of prefabricated buildings and promoting base construction.

The housing and Construction Department of Hainan province continues to promote the development of prefabricated construction industry from the aspects of policy support, talent training and government supervision.
Since then, Hainan Province has extended this policy until December 31, 2022.
According to the owner’s representative of the project, the total volume of the project is 173000 square meters.
At present, China is vigorously developing prefabricated buildings.
China railway construction completed its first green building industrial park in Hainan Province on the 29th.
