We can know what are the basis for the acceptance of the project quality. Once there is a problem with the quality of the project, it will not only lead to economic losses, but also may lead to personnel**. Therefore, whether it is design, construction or acceptance units, they should pay attention to the quality of the project, and if there is a project quality problem, it should also be dealt with and reported to the relevant departments as soon as possible.

building construction; Quality Control Qin Do 1 Introduction Engineering quality control includes the technical and management activities taken by the operation. In the construction stage, the implementation of dynamic control, supplemented by pre-control management methods, mainly grasp the prior guidance, in-process inspection, post-acceptance of the three links. Do a good job of pre-control, take the initiative to find problems from the perspective of pre-control, and dynamically control key parts and key processes.

The quality of construction projects has a direct and far-reaching impact on the healthy development of China's economy. 2. Problems in construction quality control Because construction engineering is a special product, its characteristics are manifested in the applicability, durability, safety, reliability, economy and environmental coordination of the product. In the construction process, affected by many factors such as environment, climate, personnel quality, cultural accomplishment, professional ethics, construction technology, technical measures, project cost, etc., it is inevitable that there will be different degrees of defects, which greatly reduces the quality of products.

In order to pursue greater profits, some developers give the project to contractors who have no qualification certificate and low price, and do not send professional and technical personnel to the site for management, and as a result, a black-hearted project is built with a clear conscience, such as: Quanzhou Wenling Phase II project, some beam steel bars are broken, the foundation is subsided, and the exterior wall tiles are falling. This situation occurs from time to time, in the face of these phenomena, how to strengthen quality control in construction, strengthen pre-quality control, pre-quality control is required to carry out a thorough quality plan in advance, including quality planning, management system, post setting, and establish various quality functional activities, including operation technology and management activities on the basis of full ability, condition assurance and operation mechanism.

For construction projects, especially the quality pre-control in the construction stage, it is through the formulation process of construction quality plan or construction organization design or construction project management implementation plan, and the use of target management means to implement project quality pre-control, or quality plan pre-control. Prior quality control must give full play to the advantages of the organization's technology and management, and creatively apply the advanced technology, management methods and experience and wisdom formed for a long time to the engineering project. Prior quality pre-control requires a thorough analysis of the control objectives, activity conditions, and influencing factors of the quality control object, to find out the weak links, and to formulate effective control measures and countermeasures.

Personnel: Review the participants of the project: the supervision engineer should understand the economy, technology, management, law, and have a certain amount of engineering practice experience of comprehensive technical personnel.

Therefore, it is necessary to be strict in the qualification examination and to be certified to work. The ideological quality, technical quality and physical quality of the construction team will directly affect the quality of the project.

Construction quality control is carried out in the following operations:

1. Review of quality documents.

2. On-site quality inspection: pre-start inspection, process handover inspection, concealed engineering inspection, resumption of work inspection after shutdown, sub-item, sub-project completion inspection, finished product protection inspection.

The characteristics of construction quality control are determined by the engineering characteristics of the project and the characteristics of construction production, and the construction quality control must consider and adapt to the following characteristics for targeted management.

1.The engineering characteristics of the project and the characteristics of the production of the construction.

construction of the disposable.

The fixity of the project and the fluidity of the construction production.
