The General Office of the Ministry of Housing and Urban Rural Development recently issued a notice, requiring a focus on quality issues such as sound insulation, odor interference, and leakage in urban residential projects, and carrying out key rectification efforts. The notice requires that from the date of implementation of the "Residential Project Specification" on May 1st, new residential projects must be strictly implemented in accordance with the new standards. All regions should comprehensively implement standards and regulations for residential sound insulation, odor prevention, waterproofing, etc., and refine relevant technical measures and requirements based on actual conditions. The notice emphasizes the strict implementation of standard specifications, and new residential projects must comply with the new standards. All regions should urge participating units to strictly implement mandatory standards for engineering construction. Design units shall not lower design standards under the guise of "optimizing design", and construction units are strictly prohibited from violating construction technical standards during construction. The notice requires strict review of construction drawing design documents, with sound insulation, odor prevention, and waterproofing as key review points. We must strictly control the inspection of materials entering the construction site and resolutely prevent inferior building materials such as "engineering windows" and floor drains from entering the construction site. All regions should strictly implement the system of inspecting building materials before use, increase supervision and inspection efforts, promote testing agencies to take samples at construction sites, ensure sample randomness and representativeness, and strictly prohibit false sampling and sample submission. The notice emphasizes the need to conduct physical performance testing and include the test results in the residential quality assurance certificate. Before the completion and acceptance of residential projects, various regions should urge the construction units to organize physical performance tests such as sound insulation, odor prevention, and waterproofing. At the same time, it is necessary to organize full chain supervision and inspection, and severely punish non compliant and dishonest enterprises in accordance with the law. Each region should organize and carry out full chain supervision and inspection of the design, materials, construction, and acceptance of new residential projects, and promptly report any problems found.
