6. Quality supervision and control measures for engineering materials.
The quality of engineering materials directly affects the quality level, structural safety, external modeling and use function of the entire building of the project. Our company's supervision engineer on the quality of the project quality control in the project construction supervision occupies an important position, quality control should be pre-controlled, supplemented by process control, quality control of engineering materials is one of the important contents of quality pre-control, our company mainly from the following aspects of supervision and control.
1. Establish and improve the quality assurance system and strengthen contract management.
Because the engineering quality accidents and various losses caused by the poor quality of engineering materials are often very serious and difficult to make up and repair, therefore, such problems must be avoided and prevented in the project. In the quality supervision of materials, the construction unit is first required to establish and improve the quality assurance system, so that the construction enterprise in the staffing, organization and management, testing procedures, methods, means and other aspects of the management to strengthen management, at the same time, it is recommended that the owner in the construction contract to clarify the quality requirements and technical standards of the materials, and clarify the supervision party in the material supervision responsibility, authority and relevant requirements.
For example, the supervising party has the right to conduct necessary sampling inspections on the materials (the costs incurred shall be borne by the owner);When the construction unit samples the material test, it must be carried out under the witness and supervision of the supervision party, and strictly implement the sealing and signing procedures, and the supervision will track the whole process of sampling, sealing, sending samples and taking test reports to ensure the representativeness and fairness of the test results. In the process of project implementation, strictly in accordance with the contract, strengthen contract management, based on the contract, adhere to the construction unit self-inspection and supervision party sampling, re-inspection, to the construction unit self-inspection, supervision party re-inspection as the standard for evaluating the results of self-inspection, but also adhere to the combination of visual inspection and detection, sampling and monitoring, direct control and indirect control, etc., to prevent unqualified materials from being used in the project, to ensure the quality of engineering construction.
2. Clarify the material supervision procedures and prepare targeted supervision rules.
During the implementation of the project, the owner actively establishes the image of the supervision unit and clarifies its position in the project management, so that the participating units can clarify the nature, methods and supervision procedures of the supervision work. According to the actual situation of the project, the project supervision department formulates detailed supervision plans and rules, and clarifies the material supervision procedures. In the material supervision rules, clarify the responsibilities, working methods, steps, means of the material supervision engineer, as well as the quality requirements of the material and the measures to be taken to ensure the quality. In the process of material supervision, the supervision engineer will work in strict accordance with the material supervision plan and rules to ensure the regularization of the material supervision work.
3. Carefully review the material plan of the construction unit.
After the material supervision engineer enters the site, first understand the overall material plan of the construction unit, and review whether it meets the requirements of the total construction schedule, put forward suggestions for improvement on the problems found, so that the overall plan of the material is consistent with the construction schedule, on this basis, before the 25th of each month, the construction unit is required to submit the material entry plan for the next month to the supervision party, including the purchase variety, quantity, manufacturer, etc., the material supervision engineer shall be reviewed according to the monthly schedule of the project, so that the material entry plan meets the requirements of the project schedule.
4. Quality supervision of material procurement.
For the materials planned to enter the site, the supervising engineer will review the qualifications and quality assurance measures of the manufacturer with the construction unit, and provide samples for the ordered products and require them to provide a warranty, and re-inspect the quality of their samples according to the items listed in the warranty letter.
5. Quality supervision of incoming materials.
Strengthen the on-site raw material test (re)inspection work, for example: the steel bar and cement used in the project are required to have a factory certificate, sand, stone, brick, etc. must have a material test sheet, and the construction water must have a water quality test report, so as to grasp its technical parameters. At the same time, it is required in the construction contract to clearly stipulate that in order to improve the reliability and accuracy of the test (re)test data and ensure the quality of the project, the owner agrees that the supervision party shall independently conduct necessary inspections on the quality assurance content specified in the "Quality Inspection and Evaluation Standards for Construction and Installation Projects" promulgated by the Ministry of Construction. Inspection, the inspection work of the construction unit should be carried out in the laboratory with the specified level of experimental qualification identified by the supervision party (if the competent department has higher requirements, according to the requirements of the competent department), the supervision party is responsible for the review to confirm the authority and fairness of the test (re)inspection report provided by the construction unit.
When supervising and identifying the laboratory qualification, focus on the following aspects: the laboratory qualification level should meet the requirements of the project scale, the qualification scope should meet the requirements of the special test, there is a strict management system, there are competent, strong sense of responsibility, test personnel with specified qualifications, and can strictly implement the relevant national and local regulations.
The quality of on-site materials is strictly controlled by the supervision party in accordance with the material quality monitoring process, national norms, relevant standards, design documents, contracts and material supervision rules. In addition, the management regulations of Party A shall be strictly implemented, and the contractor will be required to report to the owner for approval and confirmation in a timely manner for the materials and contractors subcontracted by Party A.
