Tongliao Prefabricated Assembled Housing

Tongliao City has established a comprehensive promotion system for prefabricated assembled housing, encompassing policy guidance, technological promotion, project application, incentive support, and regulatory oversight.

Clear Policy Objectives and Well-Defined Phased Planning

Tongliao City has set a target for prefabricated buildings to account for over 30% of newly constructed floor area by 2025, with government-invested projects reaching 70%. This target provides quantitative guidance for the development of prefabricated buildings, facilitating their transition from pilot demonstrations to large-scale applications. The policy also emphasizes phased implementation, such as requiring that from 2026 onwards, the proportion of prefabricated construction in affordable housing, schools, hospitals, and other projects should be no less than 40%. New public buildings in urban areas of counties and banners will fully adopt standardized designs with an assembly rate of ≥30%, forming a promotion pattern of “municipal-level coordination + regional implementation.”

Technological Promotion Focuses on the “New Three Panels,” with Consideration for Upgraded Applications

Since 2024, Tongliao City has prioritized the promotion of the “New Three Panels” technology in prefabricated buildings:

• Building Insulation and Structural Integration Panels: Enable simultaneous construction of the insulation layer and the main structure, enhancing building energy efficiency and durability;
• Prefabricated Internal Partition Panels: Standardized production reduces on-site wet operations, shortens construction periods, and lowers pollution;
• Composite Floor Panels: Combine prefabricated base panels with cast-in-place layers, balancing construction efficiency and structural safety.
  Additionally, regions with suitable conditions can further apply prefabricated stair panels, forming a technological system of “basic three panels + optional upgrades” to meet the needs of different projects.

Project Applications Span Multiple Sectors, with Emerging Typical Cases

• Residential Sector: Projects such as Tongliao **** Jiayuan **** (assembly rate ≥50%), Tongliao **** Yayuan **** (12 prefabricated shear wall structure buildings), and Tongliao **** Public Rental Housing **** (steel structure modular system) have entered the construction bidding phase, reflecting diverse explorations of prefabricated technology in the residential sector.
• Public Building Sector: The expansion of the high school department of Tongliao **** Experimental **** School adopts a system of composite floor panels + prefabricated stairs + ALC wall panels. The renovation and expansion of the fever clinic at Tongliao **** Hospital **** applies modular container houses + a light steel structure main body, explicitly incorporating prefabricated technology clauses into the bidding documents to promote standardized and modular construction of public building projects.

Incentives and Oversight Work in Tandem to Ensure Development Quality

Projects adopting the “New Three Panels” and higher-level prefabricated panels can benefit from relevant incentive policies for the development of prefabricated buildings, reducing application costs for enterprises. Meanwhile, the Tongliao Housing and Urban-Rural Development Bureau, in collaboration with multiple departments, strictly oversees the entire process from project initiation, design, and construction to completion acceptance, ensuring project quality and safety, avoiding quality hazards due to technological promotion, and forming a virtuous cycle of “policy guidance + market-driven + regulatory safeguards.”
