Prefabricated Component Assembly House

Prefabricated component assembly houses are a type of prefabricated building, constructed through factory-made components and on-site assembly and installation.

Definition and Types

Prefabricated component assembly houses transfer a significant amount of on-site work from traditional construction methods to factories. Building components and accessories, such as floor slabs, wall panels, stairs, and balconies, are processed and manufactured in factories, transported to construction sites, and assembled and installed using reliable connection methods. They mainly include types such as prefabricated concrete structures, steel structures, and modern timber structures.

Construction Characteristics

• Standardized Design: Utilizing unified design standards and specifications, components are made with versatility and interchangeability, facilitating large-scale production and construction.
• Factory-based Production: Producing components in factories allows for precise control over the production environment and process parameters, ensuring component quality and precision while improving production efficiency.
• Assembly Construction: Transporting prefabricated components to construction sites for assembly and installation reduces on-site wet work and manual operations, resulting in faster construction speeds and less susceptibility to environmental factors such as weather. For example, the prefabricated components in Jiangbei, Ningbo, are all panel structures connected by mechanical bolts, enabling extremely rapid on-site installation, with a prefabricated house assembled in just seven days.
• Information Management: Leveraging information technology to manage and monitor the entire process of design, production, and construction, enabling information sharing and collaborative work, improving management efficiency and decision-making科学性 (scientificity, here translated as 'scientific nature').
• Smart Applications: Introducing smart technologies and equipment, such as smart sensors and automated production lines, to enhance the smart level and functionality of buildings.

Development Significance and Policy Support

The development of prefabricated buildings represents a significant transformation in construction methods, contributing to resource and energy conservation, reduced construction pollution, and improved labor productivity and quality and safety standards. Currently, local governments are actively promoting the development of prefabricated buildings. For instance, by 2025, the proportion of newly started prefabricated buildings in Hainan Province is expected to reach 80%. Starting from 2026, all residential land parcels sold in Guangzhou will implement prefabricated construction, while commercial and industrial land parcels will adopt prefabricated construction wherever technically feasible.
