Beijing Prefabricated House Design

Beijing prefabricated house design encompasses multiple aspects, including system innovation, policy regulations, professional services, and project practices.

1. Innovative Design System

The E-MIC prefabricated concrete box-type housing system is a typical representative of Beijing's prefabricated house design. This system adopts a modular design approach, breaking away from the traditional concept of 'one module per room'. By arranging three basic units—prefabricated modules, beams, and slabs—in an 'alternate arrangement' pattern, it reduces module usage by 30%-40%. Its advantages include:

• Improved Material Efficiency: The reduction in module usage directly lowers material consumption, while optimizing structural layouts results in higher usable floor area ratios;
• Accelerated Construction Speed: Modules can be quickly 'stacked' like drawers, shortening the construction period;
• Enhanced Spatial Flexibility: The diverse combination methods of modules make them suitable for various scenarios, including urban renewal, residential, and office applications.

2. Policy and Regulatory Support

The Beijing Municipal Commission of Planning and Natural Resources issued the 'Beijing Administrative Measures for the Design of Prefabricated Building Projects', which clarifies the full-process requirements for prefabricated building design, including:

• Design Depth Standards: Specifies the design content for each stage from scheme to construction drawings;
• Technical Proposal Review: Requires the submission of documents such as prefabrication rate calculations and structural safety analyses;
• Construction Drawing Review Points: Covers key technical details such as component connections, fire protection, and waterproofing. This policy provides a standardized and regulated framework for prefabricated house design, ensuring full compliance throughout the project lifecycle from planning to implementation.

3. Professional Service Support

As a pioneer in the industry, the Beijing Prefabricated Construction Engineering Research Institute Co., Ltd. offers full-process, multi-disciplinary consulting services:

• Full-Process Consulting: Covers project planning, scheme optimization, construction drawing deepening, and component production guidance;
• Multi-Disciplinary Integration: Integrates four major systems—structure, enclosure, equipment, and interior decoration. For example, in the COFCO Vanke Holiday Scenery project, it simultaneously designed prefabricated exterior walls, stairs, and composite slabs;
• Technical Challenge Solutions: Provides solutions for key issues such as thermal bridges in connectors and insulation systems. For instance, Zhongheng Building adopted non-metallic fiber composite material connectors to eliminate thermal bridge effects.

4. Typical Project Practices

Several prefabricated housing projects in Beijing have validated the feasibility of the design system:

• Zhongheng Building: Adopts a prefabricated shear wall system with a 'sandwich' exterior wall panel structure consisting of '50mm concrete finish + 50mm insulation layer + 200mm structural layer'. The insulation system uses Thermomass insulating sandwich panels to achieve high energy efficiency;
• COFCO Vanke Changyang Peninsula: The design includes composite floor slabs, prefabricated balconies, and air conditioning panels. Through standardized component production, it improves construction efficiency and quality.

These cases demonstrate that Beijing's prefabricated house design is driving the construction industry towards efficiency, greenness, and sustainability through technological innovation, policy guidance, professional services, and project practices.
