First, what constitutes a crime of lowering the engineering quality standard depends on the specific circumstances and consequences. 1. If the quality of the construction project is not in conformity with the contract due to the fault of the employer, the employer has the right to require the construction project to be repaired or reworked or rebuilt free of charge within a reasonable period of time. After repair or rework, reconstruction, resulting in overdue delivery, the construction party shall bear the liability for breach of contract. Article 11 of the Interpretation stipulates: "If the contractor refuses to repair, rework or rebuild the construction project due to the fault of the employer, the employer shall request to reduce the payment for the project, which shall be supported." Sometimes, the reasons for the contractor's unqualified project quality may violate the legal provisions, such as cutting corners and modifying drawings without authorization. If their actions violate relevant laws, they will also be punished by law. Article 74 of the Construction Law: "Construction enterprises cut corners during construction, use unqualified building materials, building components and equipment, or other acts that do not follow the engineering design drawings or construction technical standards, shall be ordered to make corrections and be fined; If the circumstances are serious, it shall be ordered to suspend business for rectification, lower its qualification level or revoke its qualification certificate; If the quality of the construction project does not meet the prescribed quality standards, it shall be responsible for rework and repair, and compensate for the losses caused thereby; If a crime is constituted, criminal responsibility shall be investigated according to law. " 2. Treatment of quality nonconformity caused by the contractor's fault Article 9 of the Regulations on Quality Management of Construction Projects stipulates: "The construction unit must provide the original materials related to the construction project to the relevant survey, design, construction, project supervision and other units. The original data must be true, accurate and complete. " Article 14 of the Regulations on Quality Management of Construction Projects stipulates: "If the construction unit purchases building materials, building components and equipment according to the contract, it shall ensure that the 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 ". However, in actual work, construction units often violate the above provisions. Some of these situations are due to negligence, and some are for the benefit of the construction unit. Article 12 of the Interpretation stipulates: "If the contractor has any of the following circumstances, resulting in defects in the quality of the construction project, it shall bear the fault liability: (1) providing a defective design scheme; (two) provide or specify the purchase of building materials, building components and equipment that do not meet the mandatory standards; (3) directly appointing a subcontractor to subcontract professional projects. If the Employer is at fault, it shall also bear the corresponding fault liability ". second, what content does the construction project quality include? The construction project quality refers to the comprehensive requirements for the safety, applicability, economy, environmental protection and beauty of the project according to the current relevant national laws, regulations, technical standards, design documents and contract stipulations. The characteristics of construction quality are mainly manifested in the following six aspects: 1. Applicability. That is, functionality refers to the various properties of the project to meet the purpose of use. Including physical and chemical properties, structural properties, usability, appearance properties, etc. 2. Durability. That is, service life refers to the service life of the project that meets the specified functional requirements under the specified conditions, that is, the reasonable service life after the completion of the project. 3. Safety. It refers to the degree to which the structural safety is ensured and people and the environment are not harmed during the use after the project is completed. 4. Reliability. Refers to the project in the specified time and under the specified conditions to complete the specified functions. 5. Economy. Refers to the cost consumption of the project from planning, survey, design and construction to the whole life cycle of the product. 6. Coordinate with the environment. Refers to the coordination between the project and the surrounding ecological environment, with the region, with the surrounding built projects, to meet the requirements of sustainable development.
third, the construction unit's project quality management system 1. General contract responsibility system for project quality: the general contractor is responsible to the construction unit for the project quality of each part of the project. Submit the technical quality summary of the month to the owner's supervision every month. 2. Technical disclosure system: adhere to the principle of ensuring construction quality with technical progress. The technical department should prepare targeted construction design and actively adopt new technologies and new processes. 3. Material approach inspection system: all kinds of materials such as steel bars, cement and concrete in this project need to have factory certificates, and sampling inspection shall be conducted according to the batch and quantity specified in national specifications. The unqualified materials shall not be used, and the responsibility of the acceptance personnel shall be investigated for quality accidents caused by the use of unqualified materials. 4. Model guiding system: During the construction, we should pay attention to the optimization, improvement and standardized operation of process flow, and accumulate necessary management and operation experience through continuous exploration, so as to improve the operation level of process flow and ensure the operation quality. The above is a detailed introduction to the crime of lowering the engineering quality standard. If you lower the engineering quality standard, it is likely to cause an engineering accident. What kind of crime will be constituted depends on the specific circumstances and consequences of its behavior. If you have any legal problems, I suggest you consult a professional lawyer.
