Production Process of Prefabricated Houses in the Factory

The production process of prefabricated houses in the factory is centered around modularity, integration, and intelligence, achieving efficient construction through standardized processes.

1. Modular Decomposition and Parallel Production
The production of prefabricated houses begins by decomposing the entire building into independent modules, such as the concrete house modules at China State Construction Hailong Intelligent Construction Industrial Park. Each module contains complete functional units including structure, electromechanical systems, interior decoration, and exterior finishes, enabling standardized production through modular design. Its self-developed MiC (Modular Integrated Construction) technology breaks through traditional construction sequences, transforming originally sequential processes such as structural construction, electromechanical installation, interior decoration, and exterior finishes into simultaneous production. For example, on the factory assembly line, structural framing, pipeline embedding, wall decoration, and exterior cladding can be carried out simultaneously, significantly shortening the construction period.

2. Integrated Factory Manufacturing and Precision Control
The factory adopts an integrated manufacturing model, with over 70% of processes completed on the assembly line. Taking China State Construction Hailong's vertical factory as an example, it achieves millimeter-level precision control through automated equipment and digital management systems, ensuring the accuracy of module dimensions, interfaces, and installation positions. This high-precision production not only enhances building quality but also reduces adjustments and rework during on-site construction. For instance, the pouring, curing, and surface treatment of concrete modules are all completed within the factory, avoiding the drawbacks of traditional on-site pouring affected by weather conditions.

3. Efficient Delivery and Environmental Advantages
The factory-based production of prefabricated house modules significantly improves construction efficiency. China State Construction Hailong's vertical factory has an annual delivery capacity of 20,000 to 30,000 modules, meeting the demands of large-scale projects. Since most processes are completed in the factory, on-site construction time can be reduced by over 60%, effectively alleviating traffic pressure, site occupation, and environmental pollution. For example, traditional construction requires frequent transportation of materials and equipment, whereas modular production only requires transportation of finished modules, reducing dust and noise pollution.

4. Technology Application Scenarios and Implementation Cases
As of June 2026, MiC technology has been applied in various scenarios across the country, including affordable housing, urban renewal, campuses, hospitals, and hotels. For example, in affordable housing projects, modular production can quickly provide standardized housing to meet urgent needs; in hospital projects, integrally manufactured modules can incorporate medical equipment and pipelines, shortening construction periods and ensuring functional completeness. These cases validate the advantages of prefabricated houses in terms of efficiency, quality, and sustainability.
