Modular prefab homes

Prefabricated housing (modular/assembly-based construction) is built using factory-premanufactured components assembled on-site. Compared to traditional cast-in-place buildings, it exhibits distinct characteristics and advantages:

Core Characteristics:

 - Standardized Design: Based on modular design principles, ensuring uniform component specifications, facilitating mass production and quality control.
 - Factory Production: Core structural elements (wall panels, floor slabs, beams, columns) or entire modules are manufactured with precision in a controlled factory environment.
 - Assembly-Based Construction: On-site work primarily involves lifting, connecting components, and joint treatment, significantly reducing wet trades.

Core Advantages:

 - Enhanced Construction Efficiency: Factory production and on-site assembly occur concurrently, minimizing weather delays. Project timelines can be shortened by 30%-50%, accelerating capital turnover.
 - Precision-Controlled Quality: Standardized factory production ensures accurate component dimensions and consistent strength, reducing human error and quality variations inherent in traditional site work.
 - Optimized Cost Effectiveness: Mass production reduces material waste (by approximately 20%). Shorter schedules save labor and management costs, resulting in more predictable overall project costs.
 - Green and Low-Carbon: Centralized factory production drastically cuts on-site construction waste (up to 70%), dust, and noise pollution. Precise material usage minimizes resource consumption, aligning with sustainable development goals.
 - Improved Safety Performance: Factory settings eliminate risks associated with high-altitude and open-air site work. Advanced connection technologies ensure structural integrity, with rigorously validated seismic and fire resistance performance.
 - Reduced Reliance on Skilled Labor: Lessens dependence on large numbers of highly skilled on-site workers, alleviating pressure from construction labor shortages.
