Hefei Prefabricated Assembly-type Housing

Hefei has achieved remarkable results in the field of prefabricated assembly-type housing, forming a complete system featuring large-scale application, leading technology, innovative policies, and industrial agglomeration.

I. Rich Application Examples Covering Multiple Scenarios
Hefei has validated the adaptability of prefabricated building technology through multiple typical projects. The renovation project of Building No. 14 on Mingguang Lane in Yaohai District adopted prefabricated technology, with the superstructure construction taking only 40 days and an assembly rate of 71%. The construction period was shortened by 70% compared to traditional methods, and dust emissions were reduced by over 90%, significantly improving renovation efficiency and environmental friendliness. Modian Jiayuan Phase III, as the largest prefabricated resettlement project in the province, has a total construction area of 1.07 million square meters, including 75 high-rise residential buildings with an assembly rate of 50%, achieving efficient construction of large-scale livelihood projects. The Anqing Road No. 3 Primary School Hetang Road Campus in Luyang District adopted a modular integrated building approach, becoming Hefei's first modular school project and providing a new model for educational facility construction.

II. Outstanding Technical Advantages Ensuring Quality and Safety
Prefabricated buildings achieve energy conservation, environmental protection, and quality control through standardized design, factory production, and assembly construction. Key parts adopt grout sleeve connection technology, with the grout strength reaching over C80, far exceeding that of ordinary concrete, ensuring structural safety. The designed service life of renovated buildings reaches 50 years, fully meeting seismic standards. In addition, components can be recycled, reducing resource waste. Construction noise and dust pollution are reduced by over 90%, and safety risks are significantly decreased.

III. Policy Support and Innovation Driving Development
As one of the first batch of national pilot cities for modern residential industrialization and a national demonstration city for prefabricated buildings, Hefei has formed replicable and promotable experiences through innovative measures such as the "1+5 construction model" (1 standard system + 5 key technologies), financial subsidies, and industrial worker training, and has been listed as a national model by the Ministry of Housing and Urban-Rural Development. Under policy guidance, prefabricated buildings have transitioned from pilot demonstrations to comprehensive promotion, covering various fields such as new residential buildings, public buildings, and renovation projects.

IV. Industrial Agglomeration Forming a Complete Ecosystem
As of October 2025, Hefei has cultivated 174 core enterprises in the prefabricated industrial chain, with an annual output value of nearly 100 billion yuan, covering all aspects such as design, production, construction, and decoration. There are 248 prefabricated civil building projects under construction in the city, with a construction area of 26.9038 million square meters, a newly started area of 8.992 million square meters, and a cumulative total scale exceeding 60 million square meters, forming an industrial cluster supported by technology and oriented by the market.
