The Ministry of Housing and Construction strictly controls the quality of building materials from the source to ensure the safety of the project

: "
old saying in China is that mud can't get up to the wall." This sentence is also very appropriate in the field of construction engineering - if the quality of building materials is not qualified, the quality of construction works is impossible to talk about. There is no excellent quality of building materials, building quality is like no wood, passive water. The Ministry of Housing and Urban-Rural Development implemented the Two-Year Action Plan for Project Quality Governance, which not only requires construction units to strictly control quality from the construction process, but also requires enterprises that provide building materials to strictly grasp the quality and provide building materials with excellent technical indicators. Industry experts admitted that to ensure the quality of construction projects, first of all, building materials quality, if the quality of building materials is not good, nothing is used. The reality, however, is not encouraging. Some construction units in order to catch up or reduce procurement costs, often in various express or implied ways, require construction units to lower standards and the use of unqualified building materials, building components and equipment on the project. Such acts are not only seriously illegal, but also extremely harmful. For example, poor physical and mechanical properties of rebar will lead to cracks or brittle damage to reinforced concrete structure, active silicon oxide in the bone will cause cracks in concrete due to alkaline bone reaction, poor cement stability will cause concrete to burst, cement moisture, expiration, blocking, sand mud content and harmful substance content, added agent doping, etc. do not meet the requirements, will affect the strength of concrete, and susception, compactness, impermeability, impermeability, resulting in insufficient strength of concrete structure. In addition, the prefabribriced components section size is insufficient, the support anchoring length is insufficient, the pre-stress value is not reliably established, leakage or less rebar, plate cracking, etc. may be broken, collapse accidents. In real life, it is not uncommon for building quality problems caused by substandard building materials. On the evening of January 6 this year, Wuhan's "TV Asks Politics" column exposed the quality of housing in the Hoyeshan community of Donghu High-rise District. According to the Wuhan Municipal Construction Commission technical committee expert analysis, the main reason for the cracks in the house is that the masonry material ash sand brick and mortar contains a large number of expansion materials. After the problem came to light, Hu Lishan, a member of the Standing Committee of the Wuhan Municipal Committee and secretary of the East Lake High-energy District Party work committee, rushed to the scene and tasked the relevant departments to relocate and relocate the residents with more serious cracks in the walls and more severe water seepage from the roofs to prevent safety accidents. China's Regulations on Quality Management of Construction Projects stipulate that, in accordance with the contract agreement, construction units shall ensure that building materials, building components and equipment meet the design documents and contract requirements. The construction unit shall not express or imply that the construction unit uses unqualified building materials, building components and equipment. In engineering practice, according to the quality standards required by the project design documents and contract requirements, which materials and equipment are purchased by the construction unit and which materials and equipment are purchased by the construction unit , should be clearly agreed upon in the contract, and who is the procurement and who is responsible. Therefore, by the construction unitpurchase of building materials, building components and equipment, construction units must ensure that building materials, building components and equipment in line with the design documents and contract requirements. For the materials and equipment supplied by the construction unit, the construction unit shall inspect and test it in accordance with the provisions before use, and if it fails to do so, it shall not be used in the project, and the construction unit shall be notified to return and replace it. Building materials are the source of the quality of the project. The Construction Law and the Regulations on Quality Management of Construction Projects stipulate that the building materials, building components and equipment selected by the design units in the design documents shall indicate the specifications, models, performance and other technical indicators, and their quality requirements must comply with the standards prescribed by the State. Except for building materials, special equipment, process production lines, etc. with special requirements, the design unit shall not designate production plants or suppliers, may not intentionally select products with special requirements, or abuse its power to restrict the autonomy of construction units or construction units in the procurement of materials, etc. Some places do a better job of paying close attention to the quality of building materials. For example, Beijing, has established the "use with production, in good faith to ensure quality, to clear out to promote integrity, who uses who is responsible for" four principles, the establishment of "building materials use integrity management, building materials use guidance, building materials use information publicity" three mechanisms. From 2008 onwards, the pilot implementation of the main building materials procurement filing system for policy housing. In 2012, the implementation of structural materials, important functional materials and equipment procurement filing system for all construction projects for construction permits, the realization of the city's construction materials and equipment use of the whole process of traceability management. According to reports, since 2010, a total of 59 enterprises supplying unqualified building materials in Beijing have been notified and handed over for processing, and two serious construction materials supply enterprises have been restricted bidding processing. In addition, Beijing has further established a credit evaluation system for building materials enterprises, further standardize the use of construction materials in the city, and create a market environment for the supply of construction materials in good faith and in accordance with the law. Through the supply enterprise market behavior credit evaluation system, the first batch of ready-mixed concrete, waterproof materials, building windows, plastic pipes and other four kinds of construction engineering materials supply enterprises real-time collection of credit information, market behavior credit evaluation pilot, according to the credit evaluation score, classification of differentiated supervision, encourage the use of more than 80 points of supply enterprises produced building materials, strengthen the use of scores of less than 60 points of supply enterprises supervision. Shenyang Municipal Construction Commission through the establishment of a signage system, requiring construction units and material supply units, the quality of construction projects to assume the corresponding responsibility for life. According to reporters, in the future, Shenyang new projects, there must be five ways to determine the representative signed a commitment to life-long responsibility, to establish a permanent quality assurance system. In addition, to solve the quality of building materials, but also from the construction industry practitioners' ideology, because these years, China's engineering construction heavy construction quality, light building materials quality problems have not been completely improved. We must increase publicity efforts, so that everyone knows that building materials as the material basis of construction projects, its quality is good or bad for the quality of the project will be proud, all damage. From this level, the materials branch of the China Construction Industry Association to carry out the "Luban Award Engineering MeritOrity Supplier" evaluation and promotion activities are of great significance and far-reaching impact. Through the annual evaluation and promotion activities, the selection of engineering meritorious suppliers in the construction industry, and through the leading demonstration role of these suppliers, throughout the building materials industry to create a quality-grabbing atmosphere for everyone, everyone attaches importance to quality. Only in this way, in the field of construction to ensure the quality of materials, construction quality wings flying together, in order to truly realize the Chinese dream of the construction industry.
