Jiangsu Prefabricated House Construction
Prefabricated house construction in Jiangsu has developed rapidly and has become an important path for building upgrades. The following is an introduction from multiple aspects:
Development Background and Advantages: Jiangsu is located in the Yangtze River Delta region, with a rapid urbanization process and a high demand for efficient building solutions. As a strong province in manufacturing and construction, it has natural advantages for developing prefabricated house construction, providing a solid foundation for industry development.
Model and Characteristics: Prefabricated integrated houses adopt an industrialized building model, with standardized production of structural, wall, pipeline, and other components completed in factories, followed by rapid assembly on-site. Its core is 'standardized design, factory-based production, assembly-based construction, and information-based management'. Compared with traditional cast-in-place buildings, it can shorten the construction period by more than 30%, reduce on-site wet operations, lower construction waste emissions, and improve construction efficiency and environmental protection levels.
Technology and Products: High-strength steel structures or concrete prefabricated components are commonly used, combined with BIM technology for full lifecycle management. The products have high earthquake resistance and good thermal insulation properties, and can be adapted to various functional spaces. Some high-end products integrate intelligent ventilation, energy-saving lighting, and renewable energy systems to meet green building standards. Modular design also supports later expansion and functional adjustments.
Market and Prices: There are various brands and types of prefabricated houses on the market, with prices varying due to factors such as brand, specifications, and region. For example, the price of cement prefabricated movable houses from the Xuzhou Xiangfeng brand is 500.00 yuan per square meter or 500.00 yuan per set; the price of cement prefabricated houses from the Xinda brand is 368.00 yuan per square meter; the price of new assembled prefabricated houses from the Dingshun brand in Suzhou and Yangzhou is 300.00 yuan per square meter.
Policy Support and Achievements: Jiangsu Province has improved its policy, technology, standard, and regulatory systems to promote the development of prefabricated buildings. By the end of 2023, the cumulative newly started prefabricated building area in the province had reached approximately 250 million square meters, with the proportion rising from 3% in 2015 to 41.0% in 2023; multiple national and provincial demonstration cities, industrial bases, and demonstration projects have been created.
Future Potential: With policy support and technological iterations, Jiangsu's prefabricated integrated houses will continue to unleash their potential in urban renewal, rural revitalization, and new infrastructure construction, driving high-quality development in the construction industry.
