Prefabricated Housing Integration

Prefabricated housing integration generally refers to integrated construction, a building system centered around factory-based production that integrates design, materials, equipment, and management optimization, using prefabricated components to achieve assembly-based construction.

Core Definition and Technical System

Integrated construction involves factory production of prefabricated components covering structural, enclosure, equipment, and interior systems, with on-site assembly only required. Its core technology is BIM (Building Information Modeling), which runs through the entire process of planning, design, production, and construction installation, enabling precise coordination across all stages. For example, after applying C-MiC technology, the construction period of Building 8 on Huapichang Hutong in Beijing was shortened from several years under traditional methods to 90 days, while the Shenzhen Huazhang Xinzhu project achieved full decoration delivery within one year, with a 25% reduction in construction material waste.

Typical Characteristics of Modular Integrated Construction (MiC)

MiC represents an advanced form of integrated construction, dividing buildings into independent functional modules (such as bedrooms and kitchens) and completing structural, decorative, and electromechanical pipeline integration in factories. Unlike traditional prefabricated buildings that only prefabricate major components, MiC achieves prefabrication of water and electrical pipelines and over 90% factory production of components and fittings, significantly reducing on-site wet operations and labor dependency. For instance, a project in Shenzhen shortened its construction period by over 60% using MiC technology while improving quality stability through standardized processes.

Advantages and Application Scenarios

1. Efficiency Improvement: Factory production and on-site assembly occur in parallel, shortening construction periods by 50%-70% compared to traditional buildings. For example, modular construction methods can compress project timelines by over 60%.
2. Quality Control: Factory environments eliminate weather interference, achieving millimeter-level component precision and reducing common quality defects.
3. Environmental Protection and Energy Efficiency: Construction material waste is reduced by over 25%, and energy consumption is lowered through optimized design.
4. Flexible Adaptation: Suitable for residential, hotel, hospital, and other scenarios, particularly emergency housing needs (such as post-disaster reconstruction).

Typical Cases

• Building 8 on Huapichang Hutong, Beijing: Using C-MiC technology, the renovation was completed in 90 days, addressing the challenge of updating old residential communities.
• Shenzhen Huazhang Xinzhu: Achieved full decoration delivery of five residential buildings within one year, demonstrating the feasibility of MiC in high-rise construction.

Integrated construction drives the transformation of the construction industry toward efficiency and low carbon through the fusion of industrialization and digitalization, representing a core direction for future urban development.
