Xiamen Concrete Prefabricated Houses

Prefabricated concrete houses (prefabricated buildings) in Xiamen have become the mainstream model in the construction industry, boasting significant advantages such as advanced technology, policy support, and mature industrial development. They are driving the transformation of urban architecture towards efficiency, greenness, and intelligence.

1. Wide range of application scenarios covering urban construction needs in multiple fields
Prefabricated buildings in Xiamen have transitioned from pilot stages to city-wide promotion, widely applied in scenarios such as affordable housing, industrial carriers, and newly constructed public buildings. For example, the Jinyuan Building project achieved efficient construction with a high prefabrication rate (up to 91%), setting a benchmark for industrialized construction. Additionally, policies are driving the renovation of old buildings, such as the remediation of prefabricated prestressed concrete porous slab structures (hollow floor slabs), enhancing building safety and living quality through prefabricated technology.

2. Outstanding technological advantages enabling millimeter-level precision construction
Prefabricated buildings adopt factory-prefabricated components and on-site hoisting and assembly methods, significantly improving construction efficiency and reducing environmental pollution. Taking Jinyuan Building as an example, industrialized construction reduces mud and dust emissions while optimizing processes through digital technology. For instance, the prefabricated pier platform hoisting for the Xiamen-Kinmen Bridge achieves millimeter-level precision, relying on intelligent sensors and a digital brain to monitor construction data in real-time, ensuring structural safety and quality stability.

3. Synergy between policy and industry fostering a large-scale development pattern
Xiamen has introduced policies such as the "Guidelines on the Independent Renovation and Upgrading of Old Urban Residential Communities," explicitly supporting the development of prefabricated buildings and setting targets for the proportion of new construction area (45.8% by 2025). Local enterprises like Zhixin Group have achieved large-scale production, with products covering prefabricated concrete components, shield tunnel segments, etc., radiating to surrounding areas such as Fuzhou and Zhangzhou. Their technology has been recognized for national green ecological development, providing standardized solutions for the industry.

4. Impressive market data leading the province in scale and quality
The proportion of new construction area for prefabricated buildings in Xiamen continues to rise: 35.8% in 2023, increasing to 42.2% in early 2024, and expected to reach 45.8% by 2025. This data reflects increased market acceptance and demonstrates the synergistic effect of policy guidance and industrial upgrading. Prefabricated buildings, through modular design and standardized production, shorten construction periods by approximately 30% while reducing energy consumption and carbon emissions, aligning with the goals of "carbon peaking and carbon neutrality."

5. Significant environmental benefits driving high-quality transformation of the construction industry
Prefabricated buildings offer clear advantages in energy conservation and emission reduction: factory-based production reduces on-site wet operations, lowering dust and noise pollution; components can be recycled, reducing construction waste. Furthermore, the integration of digital technology further optimizes resource allocation, driving the transformation of the construction industry from labor-intensive to technology-intensive, providing sustainable support for Xiamen's urban modernization.
