(A) engineering quality assurance measures
1. Establish an experienced quality management team, directly grasp the quality, and clarify the post responsibility system of quality management. Equipped with full-time inspection team, establish the concept of quality first, and be responsible for formulating the overall planning, policy and product quality objectives of engineering construction. Supervise and inspect the implementation of quality management measures and the management of various functional departments, and coordinate the quality-related work of various departments; Organize the implementation of management system, construction process cards and quality standards.
2. The Quality and Safety Department of the Company shall implement personnel and formulate measures to be responsible for the quality and quality inspection of the whole project. Its scope of responsibility is to check the implementation of various quality measures, go deep into the construction site, put prevention first, carefully re-evaluate the quality of each working procedure, urge the construction team to do a good job of "self-inspection and mutual inspection" and "handover inspection", earnestly carry out "team quality management activities", participate in technical disclosure and process disclosure, and not carry out construction according to drawings.
3, by a full-time quality engineer with rich construction experience, responsible for the management of the construction site, directly responsible for the supervision and control of the construction quality, and is responsible for handling daily general quality problems.
4. The person in charge of unit project construction is responsible for the prior management of the whole project construction. Implement quality planning and technical measures, and be responsible for re-evaluation of each process; Responsible for handling all kinds of quality accidents, in strict accordance with the construction specifications and company standards, summarize the construction situation of each type of work team, and report the construction quality in time.
5. Establish a part-time quality controller for the team leader of each type of work, strengthen the implementation of construction procedures, operating procedures and acceptance specifications, adhere to the project quality inspection, organize construction activities within the team, and stop illegal operations.
6. Give full play to the enthusiasm and creativity of employees, take the economic responsibility system as the economic lever and work basis, link the economic interests of enterprises and employees with economic responsibility and realization effect, coordinate the management system of closely combining responsibility, right and benefit, give full play to the enthusiasm of employees, actively carry out quality management education and QC group activities among every employee, and deepen quality management.
7, the construction preparation stage of quality management:
The preparation before construction is very important and runs through the whole process of engineering construction. The quality management in the construction preparation stage directly affects the engineering quality, and the quality management in this stage mainly includes.
(1) The blue prints.the design system shall be implemented. Drawings are the basis of construction. In order to ensure the engineering quality, we must be familiar with the drawings carefully, organize self-examination and joint examination in time, and take effective measures to ensure the quality of the drawings.
(2) Work out the construction organization design and construction scheme by stages, parts and division of labor, arrange the construction sequence reasonably, and do a good job handover to avoid unreasonable crossover and quality problems.
(3) Quality acceptance of materials and semi-finished products. Ensuring the quality of materials is the premise of ensuring the quality of engineering products and the key to ensuring the quality of the whole project. The inspectors have the right to stop the use of materials, semi-finished products and equipment that do not meet the quality requirements when they find that they violate the construction procedures and do not follow the design drawings, specifications and procedures. Materials and components should be inspected by special personnel when they enter the site. Should be stacked separately according to the model, and color coded. All kinds of components and raw materials should have factory certificates and be rechecked according to regulations. It can only be used after it is qualified.
(4) Establish a regular maintenance and inspection system for construction machinery, equipment and instruments, and repair and correct all kinds of machinery and instruments that do not meet the requirements.
8, the quality management of the construction process:
The quality of the construction process is controlled under the guidance of the builder. Each construction team should carry out the construction in strict accordance with the specifications and technical standards of the company, and the quality management of the construction process plays a comprehensive role.
(1) Do a good job in technical disclosure and technical review of construction, and supervise whether the project is constructed according to design drawings, specifications and procedures.
(2) Carry out engineering quality inspection and acceptance. In order to ensure the quality of this project, we must adhere to the quality inspection and acceptance system and strengthen the inspection of all links in the construction process. The completed sub-projects, sub-projects and concealed works should be inspected in time, and the next working procedure can only be carried out after inspection and acceptance.
(3) After each lofting, it must be checked and accepted by the project leader and the technical department of the company, and approved by the owner. Axis control with theodolite lofting, elevation with level measurement.
(4) Strengthen the measurement of concrete specimen, timely detect slump by designated personnel, do a good job in the production, maintenance and pressure test of the specimen, and list the mixture ratio on site.
(5) Waterproof engineering should pay special attention to all aspects of roofing waterproof practices. Waterproof details must be handled with care.
(6) Water and electricity installation must be closely coordinated with civil engineering, and pre-embedded holes should be reserved.
(7) The notice system of form removal shall be implemented, and the technical director shall fill in the notice of form removal according to the strength value of the specimen under the same conditions, otherwise no one shall loosen and dismantle the template.
(8) Strengthen the education of finished product protection, implement the regulations on finished product protection, assign special personnel to be responsible for finished product protection, strengthen supervision, and establish a sound quality management network, which is attached.
9, the implementation of "PDCA" cycle management:
(1) Planning with scientific management methods. The quality objectives of each division of this project are excellent. Therefore, we must use excellent standards for the acceptance of various sub-projects.
(2) Establish a total quality management system, and conduct total management in the construction process, so that the project cost, benefit, quality and other indicators can achieve the expected results.
(3) After each working procedure, it must be accepted in time. The quality engineer is responsible for the acceptance of all sub-projects, and the quality acceptance of major divisions of each division: the basic division, the main division and the decoration division are responsible for the quality acceptance of the company.
(4) For the sub-projects that do not meet the requirements, each type of work team is responsible for handling them, making feasible treatment plans and putting them into practice, and re-checking the project quality to achieve the expected results.
