Prefabricated Integrated Housing

Prefabricated integrated housing is a building form that adopts a modular construction model. It divides the building into independent modules, which are prefabricated in factories and then assembled on-site. It has advantages such as a short construction period, controllable quality, and energy conservation and environmental protection, and is widely used both domestically and internationally.

Construction Model and Characteristics Prefabricated integrated housing breaks down the building into independent modules (such as ceilings, floors, water and electricity pipelines, etc.), which are prefabricated on factory assembly lines and then transported to the construction site for assembly. Unlike the series construction of traditional buildings, which involves first setting up the framework and then laying bricks and decorating, modular buildings adopt a parallel operation model. Combined with automated three-dimensional warehouses and intelligent production lines, the construction period is shortened by more than 60%. For example, a public housing project in Shenzhen, Guangdong, used 6,028 concrete modules for assembly, reducing the construction period from 2.5 - 3 years to 1 year, reducing on-site labor by about 50%, and significantly reducing environmental impacts such as noise, dust, construction waste, and traffic congestion.

Core Advantages

1. Short Construction Period: Factory prefabrication and on-site construction are carried out simultaneously, greatly shortening the overall cycle. For example, He Shi Integrated Housing Co., Ltd. has a production cycle of only 25 - 30 days, and the time from production to delivery usually does not exceed 3 months.
2. Controllable Quality: Standardized production in a factory environment reduces human errors and ensures the stable quality of details such as water and electricity pipelines and waterproof layers.
3. Energy Conservation and Environmental Protection: Modular production reduces material waste, and on-site assembly reduces energy consumption, which is in line with the trend of green buildings.
4. Easy Maintenance: The modular design facilitates later maintenance or replacement of components, extending the service life of the building.

Domestic and International Application Status There is strong demand in overseas markets. In the first four months of 2024, the export value of modular buildings by domestic enterprises through the Shenzhen port reached 1.68 billion yuan, a year-on-year increase of 19.6%, covering more than 150 countries and regions. Projects such as elderly care apartments and hotels purchased by overseas customers can be quickly assembled on-site after being shipped from Chinese factories. Domestic enterprises such as He Shi Integrated Housing (Hengshui, Hebei) sell their products to countries such as the United States and Australia. The China Construction Hai Long Intelligent Construction Industrial Park (Shenzhen, Guangdong) has an annual delivery capacity of 20,000 - 30,000 modular buildings, forming a large-scale production capacity.

Typical Cases The Shenzhen public housing project achieved efficient construction through modular technology. The annual delivery volume of the China Construction Hai Long Industrial Park reflects the domestic production capacity advantage, and the export data of He Shi Company reflects international market recognition. These cases prove that prefabricated integrated housing has become an important development direction in the modern construction field.
