After rectification, the construction unit shall submit the project completion report to the construction unit and apply for project completion acceptance.

After the construction unit receives the project completion report, the project leader of the construction unit shall organize the project leaders of supervision, construction, design, survey and other units to conduct unit project acceptance.

(5) The appearance quality shall meet the requirements.

The general contractor shall send personnel to participate in the acceptance.

For the general items of counting sampling, the primary and secondary sampling of normal inspection can be determined according to the unified standard for construction quality acceptance of construction engineering.

The professional supervision engineer shall organize the project professional quality inspector and professional foreman of the construction unit to conduct acceptance.

The chief supervision engineer shall organize the supervision engineers of all disciplines to conduct completion pre acceptance of the project quality.

➤   Acceptance contents: the quality acceptance of divisional works shall comply with the following provisions: (1) the quality of sub divisional works shall be accepted.

Divisional works shall be divided according to the following principles: it can be determined according to the nature of discipline and project location; When the divisional works are large or complex, the divisional works can be divided into several sub divisional works according to material types, construction characteristics, construction procedures, professional systems and categories.

(2) As the foundation and foundation divisional works are complex, highly professional and related to the safety of the whole project, in order to ensure the quality and strictly control the quality, it is stipulated that the project leader of the survey and design unit shall participate in the acceptance, and the person in charge of the technology and quality department of the construction unit shall also participate in the acceptance.

II.

In case of construction quality problems, the construction unit shall rectify them.

Four unit project unit project quality acceptance, also known as quality completion acceptance, is the last acceptance and the most important acceptance before the construction project is put into use.

(2) The quality of general items is qualified through sampling inspection.

➤   During the acceptance organization, under the organization of the professional supervision engineer, the project technical director of the construction unit can summarize the acceptance records of all inspection batches, report them to the professional supervision engineer for review after verification, and sign the quality acceptance records of subdivisional works by the project technical director of the construction unit after confirming that they meet the requirements, Then the professional supervision engineer shall sign and pass the acceptance.

Unit works shall be divided according to the following principles: buildings or structures that have independent construction conditions and can form independent use functions are a unit project; For large-scale unit projects, the part that can form independent use function can be divided into a sub unit project.

➤   Acceptance records the quality acceptance records of divisional works can be filled in according to appendix g of unified standard for construction quality acceptance of building works.

One inspection lot is the smallest unit of project acceptance and the basis of quality acceptance of subdivisional works, divisional works and unit works.

(2) Quality control data shall be complete.

The acceptance of divisional works is based on the acceptance of all divisional works.

(3) Since the main structure directly affects the use safety, building energy conservation is a basic national policy, which is directly related to the national resource strategy and sustainable development, it is stipulated that the project leader of the design unit shall participate in the acceptance of these two divisional projects, and the person in charge of the technology and quality Department of the construction unit shall also participate in the acceptance.

Among the ten divisional works included in the construction project, the personnel participating in the acceptance can be in the following three situations: (1) except for the three divisional works of foundation, main structure and building energy conservation, the acceptance organization of the other seven divisional works is the same, that is, it is organized by the chief supervision engineer and attended by the project leader and project technical leader of the construction unit.

After the completion of unit works, the construction unit shall organize relevant personnel to conduct self inspection.

The engineer must be clear that the construction project quality shall be organized by the responsible party for project quality acceptance on the basis of the self inspection and qualification of the construction unit, with the participation of relevant units of project construction The quality of unit works and concealed works shall be subject to sampling inspection, the technical documents shall be reviewed, and the project quality shall be confirmed in writing according to the design documents and relevant standards.

The acceptance of subdivisional works is based on the inspection batch.

(4) The appearance quality shall meet the requirements.

The construction project is divided into “inspection lot → subdivisional works → divisional works → unit works” and the method of gradual acceptance has been adopted and standardized by the industry.

➤   Acceptance record the quality acceptance record of the inspection lot can be filled in according to Appendix E of the unified standard for construction quality acceptance of building engineering, and the original record of on-site acceptance inspection shall be provided when filling in.

(3) Have complete construction operation basis and quality acceptance records.

When counting sampling is adopted, the qualified point rate shall comply with the provisions of relevant professional acceptance specifications, and there shall be no serious defects.

The source of the sub part of the works is the Luban alliance of the construction project.

➤   Acceptance records quality acceptance records of subdivisional works can be filled in according to Appendix F of unified standard for construction quality acceptance of building works.

In the acceptance of subdivisional works, if there is doubt or objection to the acceptance conclusion of the inspection batch, corresponding on-site inspection and verification shall be carried out.
