Model 2First, the project quality acceptance
1, civil engineering:
(1) civil engineering single acceptance engineering work process
construction unit in the completion of a single project in the course of construction, by the A side of the infrastructure office of the construction workers and supervisory company supervisors throughout the supervision and tracking of the construction, when every single project is completed, the construction unit for self-checking, qualified, and then by the infrastructure office of the construction worker and supervising company supervisor, follow up the construction, when each completed single project, the construction unit for self-checking. Qualified, and then by the infrastructure construction, supervisory company supervisors qualified after the initial inspection by the construction unit to submit a written application for single project acceptance report, by the infrastructure division of the organization of the relevant units of personnel, according to the construction specifications, design drawings and requirements for a comprehensive acceptance, qualified to make a single project acceptance of the information before the next step in the construction of the single project.
(2) key acceptance parts
① excavation foundation is completed, the construction unit submitted a written acceptance application report, by the design unit of the designers *** with the participation of acceptance, such as hidden works, the need for the design unit to provide hidden works construction program, by the Office of the Construction Division of the construction workers and supervisors supervise the completion of the construction unit to do a good job of all the information and written acceptance application report, the construction workers, supervisors and supervisors, the construction unit to do all the information and written acceptance application report. The infrastructure construction, supervision of the company's supervisors signed the approval, and then by the infrastructure organization units and personnel for acceptance, qualified for the next step in the process of construction.
② After the completion of the foundation is also a key part of the acceptance.
③ After the completion of the single layer is also a key part of the acceptance.
④ After the completion of the main body is also a key part of the acceptance.
⑤ After the completion of the decorative work is also a key acceptance part.
⑥ water, electricity, heating is the key acceptance part.
⑦ Reinforced concrete work is the key acceptance part.
2, participating units and personnel:
Infrastructure Division is responsible for the organization, the construction of specific projects in the Infrastructure Division of the construction staff, the person in charge of the Infrastructure Division, the supervisory company supervisors and superintendent or the technical director, deputy director of the Office of the General Engineer, the construction unit technicians, construction personnel, the person in charge of the participation of the Office of the Audit sometimes participate in the construction of a random check more often.
After the completion of the project, the construction unit by the construction unit after passing the self-inspection, written application for the completion of the acceptance of the project, organized by the Office of the infrastructure units and personnel to participate in the acceptance and acceptance of the individual project information and to ensure that the completion of the information and the quality of the project to the project view, the use of the project as the main body of the functionality of the overall acceptance, after passing the signing and writing of the acceptance of the project.
3, reinforcing steel acceptance
At the beginning of the project, the construction side according to the project budget of the type of steel, the number of contractual design requirements, etc., the construction side of the purchase of steel, reinforcing steel batch into the site and to the Office of the Infrastructure (Supervision) to provide the origin of the product, the certificate of conformity and the material single, by the Office of the Infrastructure and construction **** with the sampling, sent to the County Quality Inspection Station for testing and qualification before being used, the test sheet into the project guarantee information. The test sheet into the project to ensure that the information. After the completion of each individual project, reinforcing cage binding support molding is completed, by the construction unit written acceptance report, by the supervisory company, infrastructure specific construction personnel and leadership, as well as the construction unit to participate in the *** with the drawings and design requirements, one by one to check and control, in line with the construction specifications and design requirements before the next step of the project, pouring concrete and visa recognition, the formation of guarantee information and settlement basis.
4, concrete acceptance acceptance
I unit in the three-phase project, in addition to individual supply pumps can not reach the location of the sporadic projects, all the use of commercial concrete, concrete supply station for each batch of concrete test blocks, sent to the county testing center for test pressure, to determine the compressive strength of concrete, as the construction side of the guarantee information, inspection work with.
All the main works of the three phases of the project are supplied by Jincheng commercial mixing plant. Road surface and other works with a small amount of Yu Wang commercial mixing station, Zouping Transportation Bureau commercial mixing station.
5, the construction of the control of mortar
construction unit transported into the sand, stone, cement and infrastructure after a piece of sampling, sent to the county testing station for testing, and then according to the design requirements: issued with the proportion of mortar with the single, in the infrastructure under the supervision of the construction staff, weighing to determine the volume of volume capacity, according to the volume of volume capacity with the mixing of mortar. Infrastructure Division, Audit Office often check, although the control is more stringent, but the human operation will be loopholes, which is the key part of the inspection.
Second, the volume of acceptance
1, the volume of work refers to the amount of construction according to the design of engineering drawings and drawings of changes, the amount of hidden works.
Concealed engineering appeared by the design department, the infrastructure office of the person in charge of technology to determine the construction program, by the construction team according to the construction program for construction, by the owner of the site construction personnel, supervisory company supervisors and construction team personnel to participate in the *** with the measurements, to confirm the amount of work, written into the project visa for the basis of the settlement of the project, the project is completed during the project, the project has been unable to determine the amount of work of the concealed after the completion of the project. The project is completed during the project, after the completion of the project has been unable to determine the amount of hidden works. Acceptance of the amount of work is also in accordance with the procedures of engineering construction of a unit project completion, auditing, acceptance and quality of the project a piece of work, after the completion of the acceptance, the vast majority of the words have been unable to complete the work, can only be seen (the exposed part of the) to do the shape of the profile test, the actual meaning is not very big. Because in the process of construction of the project has been part of the acceptance, fully able to achieve the purpose of acceptance of the project volume.
