Prefabricated Block Building Construction

Prefabricated block building construction generally refers to modular construction or prefabricated assembled construction. It achieves efficient construction through factory-prefabricated components and on-site assembly, offering advantages such as short construction periods, controllable quality, environmental protection, and energy efficiency. It is widely applied in scenarios like hotels and apartments, with a continuously growing market size.

Construction Modes

The core of prefabricated block building construction is "factory prefabrication + on-site assembly".

• Modular Construction: All components of a building, including ceilings, floors, and water and electricity pipelines, are prefabricated on factory assembly lines and then assembled on-site through hoisting and joining, similar to "building with blocks". For example, a public housing project in Shenzhen, Guangdong, was assembled from 6,028 concrete modules, reducing the construction period from 2.5 - 3 years to 1 year.
• Prefabricated Assembled Construction: This includes panel-assembled construction (e.g., prefabricated wall panels and floor slabs), box-assembled construction (prefabricated functional units), and frame-assembled construction (e.g., steel structures). Among them, modular construction is a more integrated mode, with construction speed increased by 50% - 70%.

Technical Advantages

• Short Construction Period: Parallel operations and automated production in factories shorten the construction period by more than 60%, with only about 10% of the work (such as public area treatment) needing to be completed on-site.
• Controllable Quality: Each module comes with an "ID card" (including project name, model, and production date). The precision of steel bar positioning is measured in millimeters, reducing human errors.
• Environmental Protection and Energy Efficiency: It reduces on-site noise, dust, and construction waste. Industrial bases in Fujian and other places have achieved a reduction of more than 70% in construction waste.
• Cost Advantage: In regions with high overseas labor costs, modular construction can save a large amount of on-site labor, offering significant price competitiveness.

Application Scenarios

It is widely applicable in hotels, apartments, dormitories, office buildings, hospitals, and data centers. For example, 63 modules purchased in the UK were assembled in just two weeks; a hotel project in Papua New Guinea achieved continuous repurchases through batch shipping.

Market Development

It is predicted that the global modular construction market size will exceed $142.8 billion by 2030. China's prefabricated building exports grew nearly threefold from 2015 to 2025, with a growth rate of 45% in the first quarter of 2026; the export value of movable houses in the Guangzhou Customs area reached 1.4 billion yuan in the first four months of 2026, a year-on-year increase of 38.1%.

Technical Support

It relies on a technical system, production system, and industrial cluster, requiring highly automated production lines and intelligent management (such as welding robots and three-dimensional warehouses). China's prefabricated concrete technology originated in the 1950s of the 20th century and revived in the 21st century due to environmental protection needs. Companies like Vanke have developed assembled shear wall residential structural systems.
