Specifications for Prefabricated Assembly-Type Housing
The relevant specifications for prefabricated assembly-type housing mainly include the 'Technical Guidelines for the Construction of Prefabricated Rural Houses in Shandong Province', the 'Exposure Quality Requirements and Dimensional Deviation Limits for Prefabricated Concrete Components in Prefabricated Buildings' (draft for comments), and the 'Technical Specifications for Prefabricated Concrete Structure Buildings' (draft for comments), among others.
'Technical Guidelines for the Construction of Prefabricated Rural Houses in Shandong Province': This guideline will be implemented from July 1, 2026. It defines prefabricated rural houses as rural residential buildings that are prefabricated or partially prefabricated in factories and then assembled on construction sites. Construction must adhere to the principles of modern functionality, structural safety, cost-effectiveness, environmental friendliness, and harmonious aesthetics. In terms of structural systems, it specifies the prefabricated concrete shear wall structural system, EPS module cast-in-place concrete structural system, light steel frame structural system, etc., and provides detailed design and construction specifications. Regarding materials, it advocates for adapting to local conditions and using locally available materials, prioritizing green, economical, and recyclable building materials, and using local building materials as a priority while ensuring quality. It prohibits the use of high-energy-consuming and excessively polluting materials. In design, it respects farmers' housing needs, reflects regional characteristics, and appropriately considers aging-friendly design. For construction, it is advisable to have professional construction teams or trained rural individual builders with housing construction capabilities organize the construction and prepare construction organization designs and construction plans.
'Exposure Quality Requirements and Dimensional Deviation Limits for Prefabricated Concrete Components in Prefabricated Buildings' (draft for comments): The draft for comments was released on September 3, 2025, with the deadline for feedback being October 13, 2025. This document specifies the classification, general provisions, requirements, test methods, and inspection rules for prefabricated concrete components in prefabricated buildings, applicable to the production and inspection of such components.
'Technical Specifications for Prefabricated Concrete Structure Buildings' (draft for comments): It consists of 11 chapters and 2 appendices, with main technical content including general provisions, terms and symbols, basic requirements, building integrated design, structural design, interior design, exterior enclosure design, component production, construction and installation, and acceptance. However, this draft specification for comments shall not be used as the basis for engineering design, fabrication, construction, and acceptance.
