Prefabricated Houses in Nanchang, Jiangxi
Information on prefabricated houses in Nanchang, Jiangxi, can be understood from three aspects: industrial innovation, the management of dilapidated houses, and accident cases:
Industrial Innovation and Development: Prefabricated integrated houses in Nanchang have demonstrated outstanding performance in architectural innovation. They utilize moisture-resistant OSB panels, hydrophobic rock wool, and anti-corrosion coated steel, effectively addressing Nanchang's high-humidity environment and preventing wall mildew and structural corrosion. The modular design allows for flexible assembly, adapting to various terrains, and installation does not require heavy machinery, making it suitable for areas with poor transportation access. The products also support solar integration and rainwater harvesting systems, enhancing energy self-sufficiency. Jiangxi Lvdao Integrated Building Technology Co., Ltd. is a leading manufacturer in the province, with its products widely applied in new rural construction, tourist attractions, and emergency shelters, playing a significant role in the construction of the Poyang Lake Ecological Economic Zone. The factory has incorporated phase-change temperature-regulating materials and double-layer ventilated wall designs to improve indoor thermal comfort, tailored to Nanchang's climatic characteristics. Additionally, a localized procurement strategy has been adopted to reduce energy consumption from raw material transportation. As Jiangxi Province promotes the development of prefabricated buildings, the prefabricated integrated housing industry in Nanchang is leveraging its geographical and ecological advantages to establish a green building supply base for the central region.
Management of Dilapidated Houses: As a pilot city for the national housing safety three-tier system, Nanchang's Housing and Urban-Rural Development Bureau has advanced housing insurance trials, establishing a collaborative governance mechanism involving "resident contributions, government subsidies, insurance company operations, and monitoring services," and exploring a new model of "comprehensive insurance + dynamic monitoring." Xihu District has successfully implemented this approach, treating a total of 1,924 buildings, including CD-grade dilapidated houses, buildings over 40 years old, and prefabricated panel houses, involving 75,660 households. Through public bidding, insurance institutions have been selected to manage the program on a "three-year term" basis, introducing professional service forces to design insurance plans covering property damage, temporary relocation, emergency reinforcement and repair, and personal injury protection. In terms of technological empowerment, the "Nanchang Housing and Urban-Rural Development · Xihu Model" integrates GIS, big data, and IoT technologies, using solar power to ensure stable operation of monitoring equipment and constructing an automatic data analysis and early warning system to promptly capture housing safety risk signals and implement graded and categorized dynamic monitoring.
Accident Case: On November 22, 2021, a six-story brick-concrete prefabricated panel structure dormitory building in Xinqizhou Administrative Office, Nanchang Ganjiang New Area, experienced a partial collapse, covering an area of approximately 430 square meters and resulting in four fatalities. After the accident, 183 people were urgently evacuated and properly resettled. The dormitory building, constructed in 1995, had many tenants, with property rights that could not be transferred and relatively low rent.
