Prefabricated Modular Housing Installation

Prefabricated modular housing installation involves breaking down a building into independent modules, prefabricating them in a factory, and then transporting them to the site for assembly.

Construction Process and Core Features

The installation process of prefabricated modular housing centers on industrial production. Components such as ceilings, floors, plumbing and electrical systems, walls, and bathroom waterproofing layers are all prefabricated on factory assembly lines. Each module is labeled with detailed information (such as project name, product model, and production date), and high-precision positioning technology is used to control the error in steel bar placement to within millimeters. After being transported to the construction site, the modules are quickly assembled using lifting equipment according to the design drawings to form a complete building structure, similar to the process of “building with blocks”.

Significant Advantages

1. Substantially Reduced Construction Time: Compared to traditional construction methods, the construction period can be shortened by more than 60%. For example, the total construction period for some rural housing projects has been reduced by about 50%, with some even being completed in as little as 14 days; the Beijing Haidian District Dinghuisi North Plot affordable housing project significantly improved construction efficiency through concrete modular technology.
2. Highly Controllable Quality: Factory production ensures the uniform quality of each module. Modules come with “ID card” information, and the production process strictly adheres to standards, with precise error control, avoiding human deviations that can occur during on-site construction.
3. Outstanding Energy-Saving and Environmental Benefits: Modular construction can reduce construction waste by about 80%, while also lowering on-site noise, dust, and traffic congestion, aligning with the trend of green building development.
4. Convenient Maintenance and Low Cost: Modular design facilitates later inspection, repair, and replacement, and the on-site labor requirement is reduced by about 50%, further lowering labor and time costs.

Application Scenarios and Policy Support

Currently, prefabricated modular housing is widely used in residential, school, hospital, and other fields. Governments in many parts of China are actively promoting its development, with Guangzhou and Shenzhen introducing policies to encourage its application. Beijing, through its first concrete modular affordable housing project (Haidian District Dinghuisi North Plot), is exploring large-scale implementation. As technology matures and policies improve, modular construction is expected to become one of the mainstream models for future urban construction.
