Changzhi Prefabricated Assembled Housing

The development of prefabricated assembled housing in Changzhi has formed a complete ecosystem driven by policies, with project implementation and an active market. It features clear requirements for the assembly rate, refined construction management, and significant market growth.

Strict Policy Requirements and Tiered Assembly Rate Improvements

Changzhi strictly implements Shanxi Province's '2025 Action Plan for the Prefabricated Building Industry Chain', setting clear standards for the assembly rate of newly constructed buildings:

• Basic Standard: The assembly rate for newly constructed civil and industrial buildings across the city must be no less than 30%, covering all new projects.
• Enhanced Standard: Starting from 2026, the assembly rate for government-invested public buildings, affordable housing, schools, hospitals, and other projects will be increased to 50%.
• Demonstration Standard: Provincial demonstration projects must achieve an assembly rate of over 60%, requiring that the application ratio of prefabricated components in the main structure be no less than 50%, the proportion of non-masonry enclosure walls be no less than 80%, and the separation ratio of interior partitions and pipelines be no less than 70%. Additionally, innovative methods such as BIM technology and intelligent construction management must be integrated.

Mature Project Practices and Refined Construction Management

Taking an 18-story prefabricated concrete project in Luzhou District as an example, with a total construction area of 52,000 square meters, it utilizes exterior wall panels, composite floor slabs, prefabricated stairs, and other components to achieve integrated application of the 'three panels'. The project enhances efficiency through the following measures:

• Organizational Structure: A dedicated management team is established, equipped with certified lifting commanders and grouting operators, and a joint coordination mechanism is established with the component factory.
• Construction Zoning: The layout of the component stacking area, lifting operation area, and grouting operation area is reasonable, with a tower crane coverage radius of 55 meters, meeting the needs of high-rise construction.
• Progress Control: BIM technology is used to compile a four-level progress plan, precise to the hourly lifting time of components (e.g., 20 minutes per exterior wall panel), reducing the construction period by 30% compared to traditional methods.

Significant Market Growth and Diversified Procurement Needs

As of May 2026, the prefabricated building market in Changzhi is experiencing rapid growth:

• Scale Expansion: The proportion of newly started prefabricated buildings has reached 43.7%, with an average annual growth rate of 28%, ranking first in southeastern Shanxi. Currently, there are 67 projects in the construction preparation and bidding stages, a year-on-year increase of 31%.
• Active Procurement: Recently released procurement information covers multiple fields such as concrete structures, steel structures, and interior decoration systems. For example, a center in Luzhou District is procuring standard components such as composite floor slabs and stairs, while a school requires suppliers to have the capability for modular partition wall integration.

Through policy guidance, technological optimization, and market-driven forces, prefabricated assembled housing in Changzhi is gradually becoming a benchmark for the industrial transformation of construction, providing strong support for the city's sustainable development.
