The work content of the supervision engineer’s inspection

The work content of the supervision engineer's inspection

The work content refers to the specific type or content of labor that the worker performs. It is the main content of the labor contract that determines that the worker should perform labor obligations, including The types of work, positions, work scope, work tasks, work responsibilities, labor quotas, quality standards, etc. in which workers engage in labor. The work content clause is one of the core clauses of the labor contract. The following is the work content of the supervision engineer's inspection that I have compiled for you. You are welcome to learn from it and refer to it. I hope it will be helpful to you.

Inspection work content

Inspection is a regular or irregular supervision activity carried out by supervisors on the parts or processes under construction on site. It is a daily procedure of supervision work.

1. During the quality inspection and control of the sub-projects and processes during the construction process, supervisors must conduct daily inspections of the work area under construction. The chief supervisory engineer must regularly organize various professional supervision personnel to conduct comprehensive inspections and inspections as scheduled to form an institutional system.

2. The main contents of the on-site inspection are as follows:

(1) Whether the construction is carried out in accordance with the design documents, construction specifications and approved construction plans;

(2 ) Whether qualified materials, components and equipment are used;

(3) Whether construction site management personnel, especially quality inspection personnel, are on duty;

(4) Construction operators Whether the technical level and operating conditions meet the process operation requirements, and whether the special operators are certified to work;

(5) Whether the construction environment has an adverse impact on the quality of the project;

(6) Whether there are quality defects in the constructed parts.

3. Supervisors must record daily inspections and inspections in the supervision diary of the day, and no omissions or omissions shall be allowed for major quality problems or quality hazards. It is advisable to use photography, photography and other means to record.

4. In addition to recording the detected project quality or construction safety issues, a "Supervision Engineer Notice" must be issued in a timely manner to the construction unit for signature and processing, and a reply shall be given. Important issues should be reported to the construction unit at the same time.

5. Handle the important issues detected in accordance with relevant regulations, track and monitor, and record and file.

Parallel inspection

Parallel inspection refers to the project quality inspection activities that supervisors use certain inspection or testing methods to independently conduct project quality inspection activities in a certain proportion based on the self-inspection of the construction unit. . Parallel inspection reflects the independence of project supervision and the scientific nature of the work, and is also a requirement for professional management.

1. Inspection, testing and re-inspection of incoming project materials, components and equipment shall be carried out in accordance with the sampling plan stipulated in the construction quality acceptance specifications of each major and the method agreed in the contract, and shall be based on the actual inspection conditions and data The preparation report shall be included in the supervision files.

2. Inspection and testing of sub-project inspection batches should be based on the content and standards of each professional construction quality acceptance specification. Necessary parallel testing should be carried out on all aspects of project quality control, and records should be included in the supervision files. . The number of random inspection lots shall not be less than 20% of the total number of inspection lots for the sub-project.

3. Sampling inspections of structural safety and functions of branch projects and unit projects, and inspection and assessment of project visual quality should be carried out in accordance with the "Uniform Standards for Quality Acceptance of Construction Projects" and the requirements stipulated in the contract. . The test results are recorded and included in the supervision files.

4. The acceptance of concealed projects should be subject to necessary inspections and tests in accordance with the relevant construction drawings and the relevant provisions of the construction quality acceptance specifications of each major, and should be recorded according to the facts and included in the supervision files.

5. If any project parts with unqualified quality are found during the parallel inspection, the supervisor shall not review and sign the quality control data of the corresponding project parts of the construction unit, and notify the construction unit not to continue with the next process of construction. .

6. The supervisor must sign the parallel inspection record and be responsible for its authenticity.

Extended reading: Key points and techniques of supervision inspections

1. Inspection inspection plan and arrangement

To do a good job in on-site inspections, we must do the corresponding Only with careful preparation and planning can we achieve the desired results.

< /p>

(2) Be familiar with the construction site conditions, especially the current construction parts and contents, and be aware of the key points of the planned inspection. For example: patrol inspection of the implementation of the "Winter Construction Plan" in winter, patrol inspection of the maintenance status and effect of cast-in-place concrete structures in summer, etc.

(3) Make preparations for patrol inspection tools, such as Carry commonly used measuring tools, digital cameras and necessary security supplies. Quality and safety problems or hidden dangers discovered on-site must be promptly photographed and original records kept.

2. Scope of inspections

(1) Quality of completed inspection batches, sub-items and sub-projects;

Until the re-inspection is passed, relevant issues and handling conditions will be recorded in the "Supervision Diary" and other documents to prepare for the handling and verification of relevant issues, which will provide a rich and detailed reference for regular project supervision meetings and the next on-site inspection. The information is also favorable evidence for resolving disputes during construction claims in the future.

IV. Issues to pay attention to

(1) For problems discovered during inspections, the original records should be retained immediately by taking photos, photography, and sealing the original records.

(2) Pay attention to work efficiency and work quality. Problems that can be solved immediately on site must be solved in a timely manner. Problems that cannot be solved for some reason must be solved within a time limit to avoid irresponsible procrastination and affect work and coordination.

(3) Pay attention to the working attitude and method of dealing with problems that are conducive to solving the problem. Once a problem is discovered, be careful not to get angry, glare, yell, or even insult the personality and credibility of the other party. This will cause emotional antagonism and intensification of conflicts between the two parties. Not only will the problem not be solved, but it will disrupt the overall situation and make the supervision work "passive". , embarrassment” state.

(4) We must have a scientific attitude and spirit, insist on using data to speak, and do not deal with the matter but the person. Do not rush to express your stance on issues that you are not sure about. Instead, you should familiarize yourself with, research, and make targeted decisions, express your stance, or issue notices, etc., to avoid the occurrence of specious, "maybe" and "maybe" tones.

(5) At any time, supervisors must always keep in mind the concept of "a century-old plan, quality first, safety first", strictly enforce the law, fulfill their duties, and must not fail to adhere to principles and standards. "Mash-to-mash" style of "old fried dough sticks". ;
