《建设工程质量管理条例》规定建设工程的最低保修期 :“基础设施工程、房屋建筑的地基基础工程和主体结构工程 ,为设计文件规定的该工程的合理使用年限 ;……”。这与原土建工程质量保修期 1年的规定相比变化巨大。但“工程合理使用年限”应如何确定 ?目前国家还没有统一规定 “Construction Project Quality Management Regulations,” provides the minimum warranty period for construction projects: “infrastructure projects, foundation construction and the main structure of the housing project, the design documents for the reasonable life of the project; ......”. This is a great change compared with the one-year warranty of original civil works. However, “the project reasonable use of life” how to determine? At present there is no uniform national regulations
