Prefabricated Modular Housing Factory

A prefabricated modular housing factory is a facility that disassembles buildings into independent modules, completes their manufacturing in the factory, and then transports them to the construction site for assembly.

I. Factory Production Model Prefabricated modular housing factories adopt a modular design concept, dividing the entire building into multiple independent modules, such as walls, ceilings, and bathroom units. Each module is manufactured through a standardized process in the factory, including structural frame construction, pipeline embedding, and decorative surface layer construction. For example, China Construction HaiLong Intelligent Construction Industrial Park employs a parallel operation model, assigning production tasks for different modules to various workstations for simultaneous execution. Combined with an automated vertical warehouse for precise material delivery and an intelligent production line for module assembly, the annual production capacity can reach 20,000 to 30,000 modules. Broad Homes Industrial (Hangzhou) Co., Ltd. subdivides its production workshops, integrating processes such as concrete mixing, steel bar processing, and cement board production into an assembly-line operation, forming an industrial production system similar to automobile manufacturing.

II. Core Technological Advantages

1. Standardized Design: By unifying module dimensions, interface standards, and load parameters, cross-project versatility is achieved, reducing design costs and enhancing production efficiency.
2. Factory-based Production: Module manufacturing is completed in enclosed workshops, avoiding weather interference while controlling component precision through precision equipment, with errors controlled to the millimeter level.
3. Assembled Construction: After modules are transported to the site, they are quickly assembled using lifting equipment, reducing on-site wet operations and scaffolding use, significantly shortening the construction period. Taking the China Construction HaiLong project as an example, its modular technology can reduce the construction period by more than 50%.

III. Typical Application Cases As a representative of vertical factories, China Construction HaiLong Intelligent Construction Industrial Park achieves efficient module circulation through its four-story production space equipped with a vertical logistics system, combined with BIM technology to optimize production scheduling. Broad Homes Industrial (Hangzhou) Co., Ltd. achieves automated steel bar processing through its U-shaped steel bar production workshop, coupled with the steam curing process in the prefabricated cement board workshop to ensure component strength meets standards. The practices of these factories demonstrate that the modular building model can reduce labor costs by 30% and material waste by 20% while ensuring quality.

IV. Industry Development Trends With the advancement of building industrialization policies, prefabricated modular housing factories are upgrading towards digitalization and greening. By introducing IoT technology for real-time production data monitoring, utilizing Building Information Modeling (BIM) for modular design optimization, and integrating renewable energy systems to reduce factory energy consumption, the modular building model has become a significant force driving the transformation and upgrading of the construction industry.
