Modular Construction and Prefabricated Housing

Modular construction, also known as prefabricated housing, is a building method that breaks down a building into independent modules, which are prefabricated in factories and then transported to the site for assembly. This approach offers advantages such as short construction periods, controllable quality, energy conservation, environmental protection, and ease of maintenance, with a wide range of application scenarios and a promising market outlook.

Construction Mode and Core Characteristics

Modular construction completes the production and installation of the building's main structure, enclosure, equipment pipelines, and interior decoration in factories, forming standardized prefabricated assembled spatial modules. These modules are then transported to the site and connected through assembly. Its core characteristics are standardized design, factory-based production, and assembly-based construction. Components such as ceilings, floors, water and electricity pipelines, and even bathroom waterproof layers are prefabricated on factory assembly lines, with on-site assembly resembling building with blocks.

Significant Advantages

• Short Construction Period: Factories employ parallel operations, combining automated vertical warehouses with intelligent production lines, reducing construction periods by more than 60% compared to traditional buildings. For example, a smart production line in Shandong can build a wall in 12 minutes, the construction period of a kindergarten project in Shenzhen is halved, the completion and delivery time of a public housing project in Shenzhen, Guangdong, is reduced from 2.5 - 3 years to 1 year, some rural houses are built in 14 days, and the overall construction period is shortened by about 50%.
• Controllable Quality: Factory production achieves millimeter-level precision, with each steel bar positioned in millimeters, resulting in error control far superior to manual operations on construction sites and significantly improved flatness.
• Energy Conservation and Environmental Protection: It can reduce construction waste by about 80%, material waste by 75%, and overall costs by a quarter, while significantly reducing on-site noise, dust, traffic congestion, and other disturbing factors.
• Ease of Maintenance: Modular design makes repairs more flexible and facilitates later maintenance and upgrades.

Application Scenarios and Market Prospects

Modular construction is suitable for permanent buildings under 24 meters and supports online model selection. In addition to residential buildings, it is widely used in schools, hospitals, hotels, senior living apartments, dormitories, office buildings, and other scenarios. The global demand for data center construction is driving its development, with cases such as isolation wards in Hong Kong, mobile hospitals in Shenzhen, smart rural houses in Suzhou, and Antarctic research stations demonstrating its rapid deployment and adaptability. Leveraging its full industrial chain advantages, China is promoting the export of modular construction. In the first four months of this year, the value of exported prefabricated houses through the Shenzhen port reached 1.68 billion yuan, a year-on-year increase of 19.6%, with products sold to more than 150 countries and regions. It is predicted that the global market size will exceed 142.8 billion US dollars by 2030.
