Prefabricated House Rapid Installation

Prefabricated houses, also known as modular buildings or prefabricated assembled buildings, are a construction model where buildings are disassembled into independent modules, prefabricated in factories, and then transported to the site for assembly.

I. Construction Process
The core process of prefabricated houses involves disassembling buildings into independent modules and completing the prefabrication of all components, such as ceilings, floors, and water and electricity pipelines, in factories. Through assembly-line operations, each module can be produced in parallel, and efficient management is achieved using automated three-dimensional warehouses and intelligent production lines. After prefabrication is completed, the modules are transported to the construction site and assembled through standardized interfaces, a process similar to 'building with blocks', significantly shortening the construction period.

II. Core Advantages

1. Short Construction Period: Modular buildings significantly shorten the construction period through parallel operations of factory prefabrication and on-site assembly. For example, a real estate project in Shanghai saw its construction period reduced by over 60% after adopting this model; the completion and delivery time of a public housing project in Shenzhen was compressed from 2.5-3 years to 1 year.
2. Controllable Quality: Standardized production and intelligent management in factory environments reduce human errors, ensuring consistency in component accuracy and quality.
3. Energy Efficiency and Environmental Protection: On-site cast-in-place connection technology reduces wet operations, lowering noise, dust, and construction waste generation, while also alleviating the impact of construction on surrounding traffic.
4. Convenient Maintenance: Modular design facilitates later inspection, repair, and replacement, extending the building's service life.

III. Application Scenarios and Development
Prefabricated house technology originated in the 1950s and was initially applied in factory and residential construction. In the 21st century, with technological resurgence, companies like Vanke have developed prefabricated shear wall residential structural systems and promoted prefabricated frame technology. Currently, its application scenarios have expanded from residential buildings to commercial buildings and temporary facilities. Chinese prefabricated houses are also selling well overseas due to their cost and efficiency advantages. For example, in the first four months of 2026, the export value of movable houses in the Guangzhou Customs area reached 1.4 billion yuan, a year-on-year increase of 38.1%, indicating strong demand in the international market.

Prefabricated houses, through industrialized production and modular design, have achieved a dual improvement in construction efficiency and quality, becoming an important development direction in the modern construction field.
