Quality control of the construction process.

Process quality content: first, the quality of process activity conditions; The second is the quality of the effect of the process activity. From the point of view of quality control, the two are interrelated, on the one hand, it is necessary to control the quality of the process activity conditions, that is, whether the quality of the input products of each process meets the requirements, and on the other hand, it is necessary to control the quality of the process activity effect, that is, whether the engineering products completed by the construction of each process meet the relevant quality standards.

Process quality control principle: using mathematical statistical methods, through the process part (subsample) inspection data, statistics, analysis, to judge whether the quality of the whole process is stable and normal. If it is unstable and abnormal, it is necessary to take countermeasures and measures to improve it in a timely manner, so as to achieve process quality control.

First, the construction process quality control procedures.

1. Check whether each process is operated according to the procedure;

2. Detect whether the measurement positioning is accurate;

3. Check whether the "self-inspection, mutual inspection, and handover inspection" are true;

4. Check whether the "Sub-project Assessment Form" is in line with the actual situation;

5. Check whether the acceptance of the concealed project is carried out according to the procedures;

6. Check whether the special process is carried out according to the work instructions.

Second, the main practices of quality control.

1. The whole process is tracked and monitored around the clock.

The responsible engineer shall supervise the whole process of process quality and all-weather supervision, and shall not sign and approve if the quality standards are not met, and shall be instructed to rectify within the time limit.

2 Grasp the key processes for quality control.

According to the construction progress node, highlight the key points and grasp the key processes for quality control. In order to control the quality of the key process, it is required to prepare the construction plan, organize the quality and technical disclosure, issue the work instructions, and implement the quality inspection of the whole construction process. The engineering quality management department strengthens the inspection and supervision of key processes, so that the construction quality of key processes is always under control.

3. Accept project supervision and supervise rectification.

On the basis of self-inspection, the supervision engineer shall be submitted to inspect and sign for approval, and if there is no supervision engineer to sign and approve, it shall not be used in the project or enter the next process construction. For the construction and installation issued by the supervision engineer does not meet the design requirements, construction technical standards and engineering contract agreements, or the existence of measurement, quality, safety and other hidden dangers in the rectification notice, the general contracting project management department shall timely implement, track and supervise the rectification within a limited time, until the supervision engineer verifies and signs the approval.

4. Strictly control and carry out process inspection.

Do a good job of process inspection during the construction process. First of all, the quality of the sub-project is re-inspected, and the quality of the sub-project is re-inspected and recognized on the basis of the self-inspection of the operation team; Second, the concealed project adopts continuous or full inspection and test methods, re-inspects and approves the acceptance record of the concealed project of the subcontractor, and can enter the next process of construction only after the supervising engineer verifies the visa; Third, organize the verification of the quality level of the main branch projects.

5 Systematic management for product protection.

For the products that have been completed and formed the system function, after the experience is received, the manpower, material resources and corresponding technical means are organized to protect the product until the final product is delivered to the owner.
