Prefabricated Assembly-Type Housing in Liaoning

The development of prefabricated assembly-type housing in Liaoning is supported by two core pillars: local standard specifications and industrial base practices.

I. Local Standards Provide Technical Specifications and Guidance
The 'Design Code for Prefabricated Residential Buildings' (Draft for Comment) released by Liaoning Province is a crucial technical document driving the development of prefabricated assembly-type housing. Led by Shenyang Jianzhu University, the code was compiled in collaboration with multiple units and approved as a local standard in Liaoning Province (No. DB21/T XXXX-XXXX), effective from XX/XX/2023. The code comprehensively covers the full lifecycle design of prefabricated residential buildings, including foundational frameworks such as general provisions, terminology, and basic requirements, as well as specialized technical requirements for architectural design, main structural system design, exterior enclosure system design, interior decoration system design, and equipment and piping system design. For example, in main structural system design, the code may specify parameters for connection joints and seismic performance of prefabricated concrete components; exterior enclosure system design may address key indicators such as thermal insulation, waterproofing, and airtightness. These specifications provide a unified standard for the design, production, and construction of prefabricated assembly-type housing in Liaoning Province, helping to improve project quality, reduce resource waste, and promote technological advancements in the industry.

II. Industrial Bases Drive Technological Implementation and Industrialization
Liaoning Haoran Prefabricated Construction Co., Ltd., as one of the first batch of prefabricated construction industrial bases in Liaoning Province, serves as a vital platform for the practice of prefabricated assembly-type housing. Its business scope encompasses the production, sales, and installation of concrete prefabricated components, as well as full-chain services for metal components and building materials, embodying the core model of 'design-production-construction' integration in prefabricated construction. Additionally, the company is involved in Building Information Modeling (BIM) design and consulting, optimizing component production and construction processes through digital technologies to enhance efficiency and reduce errors. Its design and production of prefabricated movable housing further expands application scenarios, meeting diverse needs such as temporary buildings and emergency shelters. The practices of industrial bases not only validate the feasibility of local standards but also reduce costs through large-scale production, providing both economic and technical guarantees for the promotion of prefabricated assembly-type housing in Liaoning Province.

In conclusion, through the coordinated development of local standards and industrial bases, Liaoning Province has established a complete system for prefabricated assembly-type housing, from technical specifications to industrial implementation, laying a solid foundation for high-quality development in the industry.
