Prefabricated Modular Housing Production

Prefabricated modular housing production is an industrialized construction process that involves breaking down buildings into independent modules, manufacturing them in factories, and then assembling them on-site.

Industrial Characteristics of the Production Process

The core of prefabricated modular housing lies in "building houses like industrial products." Its production process is divided into three stages:

1. Module Decomposition and Prefabrication: Buildings are decomposed into independent modules such as ceilings, walls, bathroom waterproof layers, and plumbing and electrical lines. All components are prefabricated on factory assembly lines. For example, steel bar positioning requires millimeter-level precision, and error control is measured by industrial standards to ensure compatibility between modules.
2. Final Assembly and Automation: After individual components are produced separately, they are precisely assembled on a final assembly platform. The application of welding robots, automated vertical warehouses, and intelligent production lines makes the final assembly process highly mechanized, reducing manual intervention.
3. Parallel Operations and Efficiency Improvement: Different modules can be produced simultaneously in the factory (e.g., walls and plumbing and electrical lines are manufactured in parallel), combined with an automated warehousing system to achieve efficient resource allocation. This model reduces construction time by more than 60% compared to traditional construction methods.

Technical Requirements and Precision Control

Modular construction places extremely high demands on design precision, requiring advance planning of the position of each steel bar, the layout of pipelines, and module interfaces. Error control is measured in millimeters. For example, China Construction HaiLong Intelligent Construction Industrial Park uses digital modeling technology to ensure full-process precision from production to assembly of modules. This "industrial-grade" design thinking avoids the accumulation of errors that often occur in on-site construction of traditional buildings.

Typical Cases and Large-Scale Applications

1. Production Capacity: China Construction HaiLong Intelligent Construction Industrial Park has an annual delivery capacity of 20,000 to 30,000 modules, demonstrating the efficiency of industrialized production.
2. Project Implementation: On May 8, 2026, the first concrete module was hoisted at the Dinghui Temple North Plot Affordable Rental Housing Project in Haidian District, Beijing, making it the first concrete modular affordable housing project in Beijing. The project uses concrete modular technology, further validating the applicability of modular construction in the field of affordable housing.

Prefabricated modular housing production drives the transformation of the construction industry toward efficiency and low carbon emissions through industrialized processes, high-precision control, and large-scale applications, providing innovative solutions for urban renewal and housing security.
