From the oil lamps in ancient times to today's bright lights, all this is the convenience brought to us by the continuous development of science and technology. Electricity is not only limited to our daily lives, it is also a necessity for the economic development of a country. Although the electric power is very developed now, and many power companies and power projects have been built, in order to ensure people's safety, the power project must do a quality inspection, so how is the quality inspection of the Tanji power project regulated?

First, the first to participate in the construction of the power project must have the required qualifications for the construction.

Second, during construction, if there is a test block that involves people's safety materials and structural safety, workers should conduct safety verification in accordance with regulations.

Third, the quality inspectors or units that inspect these safety materials should have the corresponding inspection qualifications.

Fourth, if it is a concealed construction project, after the completion of the construction, the relevant personnel should be notified to carry out a concealed acceptance and sign the acceptance documents.

Fifth, the construction quality of a project should be carried out by the construction unit to carry out a basic quality inspection.

Sixth, the architectural content of a building construction should conform to the design plan of its designer and the survey content of its inspector.

Finally, after the completion of a project, its perceived quality should be inspected by the inspector on site and the agreement should be signed after the unanimous consent of both parties.

So what is the normative control content of a project?

First of all, the first is the physical quality of this project, and almost every project cannot escape the following projects: sub-projects, unit projects and sub-projects. Among them, the sub-project is particularly complex, and it has to be completed step by step by a series of small programs.

Therefore, the inspection quality of a project needs to test all these contents.

Secondly, the completion of a project must test its function and use value. The quality and use value of a project are reflected in the reliability, quality, usability, appearance score and environmental content of the project itself. However, there is no uniformity in all these scoring standards, because all construction projects are judged by the owner, and different owners have different functional needs, so their value is assessed by the owner.

So in the process of power construction, what are some of the links we need to control?

First of all, the first one is a preparation control before construction. Before construction, a control of some preparatory conditions and various factors is a necessary condition to ensure the quality of the construction, and only when the preparation is done well, the project will be completed quickly and well.

The second is a control of the construction process. In the construction process, in order to ensure the good completion of the project, it is required to control the production quality and the implementation status and results of the project, in which the construction manager should always supervise, know and supervise whether each construction process is completed according to the quality and quantity of its tasks.

Finally, a control should be carried out for the construction acceptance. After the completion of the construction of an electric power project, the quality inspectors should conduct a comprehensive test on the quality of the project and its use value, and only through the inspection will the two parties begin to sign the project acceptance contract.

The main contents of the standard revision:

1) Appropriately adjust the provisions on the number of sampling re-inspections and tests;

2) Add provisions for the formulation of special acceptance requirements;

3) Increase the minimum sampling quantity of inspection batches;

4) Increase the building energy-saving division project, increase the aluminum alloy structure, renewable energy, solar heating and air-conditioning system Zhaoan, soil source heat pump heat exchange system and other sub-division projects;

5) Modify the sub-project division in the main sock structure, building decoration, ventilation and air conditioning and other sub-projects;

6) Add the normal inspection of the counting sampling scheme to determine the method of primary and secondary sampling;

7) Add provisions on pre-acceptance of project completion;

8) When the engineering quality control data is missing, the corresponding physical inspection or sampling test shall be carried out;

9) Increase the requirements that the inspection batch acceptance should have the on-site acceptance inspection record.

Article 56 of the Construction Law of the People's Republic of China The survey and design unit of the construction project must be responsible for the quality of its survey and design. Survey and design documents shall comply with the provisions of relevant laws and administrative regulations and the quality and safety standards of construction projects, technical specifications for construction engineering survey and design, and the provisions of the contract. The design documents selected for the building family of good materials, building accessories and equipment shall indicate their specifications, models, performance and other technical indicators, and their quality requirements must meet the standards stipulated by the state.

The quality level of power engineering should be assessed according to the division project, unit project, contract section and construction project, and the quality level of the branch project is divided into two levels such as qualified and unqualified; The quality grades of unit projects, contract sections and construction projects are divided into three grades: excellent, qualified and unqualified.

1. The score value of the sub-project is not less than 75 points, and the score less than 75 points is unqualified; Mechanical and electrical engineering, belonging to the factory processing and manufacturing of bridge metal components not less than 90 points for the qualified, less than 90 points for the unqualified. The sub-project assessed as unqualified can be re-evaluated for quality after reinforced, reinforced, reworked, and commissioned to meet the design requirements, but the score value of the sub-project shall be calculated according to 90% of its re-scoring value.

2. If all the sub-projects are qualified, the sub-projects will be rated as qualified; If any of the sub-projects is unqualified, the sub-projects are unqualified.

3. If all the projects of each branch are qualified, the project of the unit will be rated as qualified; If the project of any of the divisions is unqualified, the project of the unit is unqualified.

4. The contract section and the unit projects contained in the construction project are all qualified, and the project quality level is qualified; If the project of any unit is unqualified, the contract section and construction project are unqualified. All the divisions included in the unit project are qualified, and the unit project score is greater than or equal to 90 points, and the quality grade is excellent; All the projects included in the division are qualified and the score is greater than or equal to 75 points and less than 90 points, and the quality level is qualified; Otherwise, it is ineligible.

1. What is the quality acceptance procedure of power engineering?

1. The inspection batch and sub-project should be accepted by the supervising engineer (the technical person in charge of the project of the construction unit) and the person in charge of the professional quality (technology) of the project of the construction unit.

2. The division project should be accepted by the chief engineer (the project leader of the construction unit) to organize the project leader of the construction unit and the person in charge of technology and quality. The survey of the foundation and foundation, the main structure division project, the project leader of the design unit and the technical and quality person in charge of the construction unit are accepted.

3. After the completion of the project, the construction unit shall organize relevant personnel to conduct inspection and evaluation, and submit the project acceptance report to the construction unit.

4. After receiving the project acceptance report, the person in charge of the construction unit (project) shall organize the construction (including subcontracting of leased branches), design, supervision and other units to carry out the acceptance of the project.

5. After the quality acceptance of the unit's project, the construction unit shall submit the completion report and relevant documents to the construction administrative department for the record within the specified time (15 days).

After receiving the delivery notice from the construction unit, the construction unit shall organize the completion of the project such as construction and design loss on the basis of making preparations for acceptance, and carry out the completion white inspection after meeting the conditions for use, and then issue a delivery notice to the construction unit. After receiving the delivery notice from the construction unit, the construction unit shall organize the construction, design and other units to jointly carry out the delivery and acceptance on the basis of making preparations for acceptance.

1) Completion self-inspection.

The completion self-inspection, also known as the completion pre-inspection, is that the construction unit first conducts an internal self-inspection to prepare for the formal acceptance. On the one hand, check the quality of the project, find problems and remedy them in time; On the other hand, check whether the as-built drawings and technical data are complete, and summarize and sort out the relevant technical data.

1.The implicit basis of the standard completion self-inspection is: whether the completion of the project meets the requirements of the construction drawings and design; Whether the quality of the project meets the standards and requirements stipulated by the state and local governments; Whether the project meets the requirements and standards specified in the contract.

2.The method of completion self-inspection, the completion self-inspection should be layered, segmented, and divided into rooms, and the completion self-inspection personnel shall inspect them one by one according to the content of each self-cooking stove. In the inspection, it is necessary to make records, determine the repair measures and standards for the parts and projects that do not meet the requirements, and designate a special person to be responsible for the completion of the project on a regular basis.

3.The composition of the completion self-inspection personnel shall be organized by the project manager of the construction unit to participate in the production, technology, quality, contract, budget and relevant construction foreman.

2) Re-examination. On the basis of the self-inspection of the grass-roots construction unit, and after all the problems found are solved, all the remaining problems will be solved through the re-inspection of the superior department, and full preparations will be made for the formal acceptance.

3) Formal acceptance.

On the basis of completion self-inspection, confirm that all projects meet the completion acceptance standards, and the formal acceptance of power engineering projects can be carried out when the conditions for delivery are met.

1.The construction unit shall send the "Completion Acceptance Notice" to the construction unit 10 days before the date of formal completion acceptance.

2.Submission of completion acceptance materialsThe completion acceptance materials shall include the following contents: an overview of the completed project; Drawing triage records; material substitution approval order; construction organization plan and technical disclosure materials; Materials, components, finished products factory certificate and inspection report; construction records; Power engineering construction test report; Completion self-inspection record; Hidden inspection records; power engineering quality inspection and evaluation data; change records; as-built drawings; Construction diary.

3.Organize the acceptance work of the project, and the completion and acceptance work of the project shall be invited by the construction unit to participate in the design unit and the section to participate, and the inspection and acceptance shall be carried out together with the supervision unit and the construction unit.

The above explains in detail the legal acceptance procedures that should be taken when the completion of the project, only if the provisions of the procedure are fully complied with, can the completion be done well, and only when it is put into use to ensure that there is no accident, can the construction of the project be better put into use.
