In order to strengthen the supervision of engineering quality, the Provincial Housing and Urban-Rural Construction Department recently issued a circular to further strengthen the quality management of ready-mixed concrete and strictly prevent major engineering quality accidents.
"Notice" requires that housing construction departments at all levels in urban and rural areas must strengthen the quality supervision of ready-mixed concrete in strict accordance with laws and regulations, strictly implement various laws, regulations and technical standards, and compact the quality management responsibilities of construction, design, construction, supervision, ready-mixed concrete, testing and other units for concrete structure projects. Strengthen the whole chain management of production, transportation, construction and acceptance to ensure the overall quality of the project.
The construction unit shall strictly implement the laws and regulations on project contracting, and shall not directly contract the professional subcontracting project of ready-mixed concrete, and reasonably determine the construction period of the project. Ready-mixed concrete enterprises should establish a sound quality management system and strengthen the management of raw materials entering, testing, production, sales and transportation. In the aspect of site quality management of ready-mixed concrete, it is necessary to strengthen the management of concrete entering the site and pouring process. The supervision unit should strengthen the verification of the strength grade of concrete entering the site, strictly prohibit the occurrence of concrete mixing, and strictly urge the construction unit to prepare and implement the special construction scheme for concrete pouring of different strength grades of beam and column nodes according to the design and specification requirements. The testing unit shall carry out testing on concrete test blocks in strict accordance with laws, regulations and relevant technical standards, and timely report the violations of laws and regulations and unqualified test results found in the process of witness sampling and testing to relevant units and departments.
In terms of supervision and management of ready-mixed concrete, urban and rural housing construction departments around the country should establish and improve the dynamic management mechanism of ready-mixed concrete enterprise qualification, strengthen the daily supervision and management of ready-mixed concrete professional contracting qualification, and carry out regular supervision and inspection. We should focus on the municipal projects under construction using ready-mixed concrete and related ready-mixed concrete enterprises, strengthen the quality management of ready-mixed concrete, and incorporate the special inspection of ready-mixed concrete into the annual inspection plan. It is necessary to comprehensively strengthen the information construction of the production, transportation, use and acceptance of ready-mixed concrete. We should strengthen the punishment and market clearance of illegal ready-mixed concrete enterprises, and seriously investigate and punish illegal production, the use of substandard raw materials, and the falsification of test data according to law; Strengthen the punishment for violations of concrete quality laws and regulations at construction sites, use unqualified ready-mixed concrete at construction sites, fail to inspect ready-mixed concrete as required, or fail to sample and test test blocks, test pieces and related materials involving structural safety, punish them strictly according to the upper limit according to law, and resolutely prevent the existence of abnormal ready-mixed concrete. Ensure the quality of construction projects.
