Quality management at construction sites

Quality management at the construction site

Construction enterprises must use modern management ideas and methods, establish their own quality system in accordance with IS09002 international quality management standards and maintain effective operation, covering all construction projects And the entire process of construction of each project can ensure that the company's quality level continues to improve and remain invincible in the fierce competition in the market.

1. Quality first, prevention first, highlighting the team’s pre-control role

Quality pre-control should start from the top And pass it down and vertically, one link after another. Team quality pre-control is the most direct and critical part, which can effectively realize the quality intention of project management. As a "team quality pre-control", there is no established model for reference, and there is no ready-made example for imitation. Only one operating model is provided for discussion.

1. Before the construction of each process, the construction team should set process quality goals based on their own business level and project control quality requirements. The requirements are specific, detailed, and targeted, and for each operation All points are clearly defined and submitted to the technical supervisor for approval.

2. According to the approved quality objectives, formulate supporting reward and punishment regulations, which require clear rewards and punishments, heavy rewards and heavy penalties, strong feasibility, and comprehensive coverage. Every decomposable quality pre-control point must be Don't let it go.

3. Based on the team’s own construction characteristics and the process requirements of the construction division, combined with the set quality goals, analyze the factors that may affect quality, formulate effective measures in a purposeful and foreseeable manner, and prepare quality reports Pre-control plan.

4. Explain the quality pre-control plan and quality objectives to the workers, and explain the stakes, so that the workers have standards in mind, construction guidelines, and a tightrope on their heads.

5. For sub-projects with new technologies, new materials, new processes and insufficient construction experience, personnel should be trained in advance and the construction process should be determined through tests or prototypes. For quality control difficulties, mass QC group activities are organized to tackle key problems. In construction management, we must also adhere to the "model guide", that is, before the full construction of each sub-project, we first organize skilled operators to make model walls, model rooms or model floors.

2. System standardizes behavior and innovative leadership thinking

Before starting construction, a technical quality master plan should be formulated based on the actual situation of the project as a control document for the overall construction quality. During the construction process Based on the progress of the project image, China Re formulates a process operation system for each process and sets process quality goals. In the formulation and implementation of the system, China Re improves transparency. The system is drafted by the technical supervisor and then distributed to each business office and each major team. Conduct a democratic review and make revisions based on the feedback from the democratic review. Only after the final internal vote of the project is passed can the on-site construction guidance be formally written. After the formal system is issued to the team, it will be implemented in the form of bulletin boards, slogans, mobilization meetings, etc. Promote it widely in the form of making it deeply rooted in the hearts of the people. During on-site construction, construction technicians are required to have a deep understanding of the relevant systems. In quality control, law enforcement must be strict and violations must be punished. Violations of the quality system and violations of quality disciplines must be severely punished and never tolerated, and a handling decision must be issued on the spot. , posted a notice;

In actual construction, I also realized that: with the same technology and the same materials, if we want to make the project quality superior to others, it is not enough to rely on on-site control and strengthen management. We must rely on innovation to win by surprise; at work, we should use innovation to lead our own work thinking, and mobilize experienced front-line workers to actively make suggestions for "difficult and difficult problems" in on-site quality, and implement a "prize-based" system for rational suggestions. , which is of great benefit to improving workers’ awareness of participation and tapping the wisdom of the masses. In many years of on-site construction, we have adopted eleven relatively effective and innovative construction methods, eight of which were proposed by workers.

3. Strict quality procedures and strengthen control

We must pay attention to procedures in everything and have rules to follow to ensure that the work is systematic and organized. We carry out quality management based on The most important thing is the ISO9002 quality assurance system. In order to make the quality procedures not just a formality and empty talk, but to truly implement them, we should establish a project manager as the core, with the technical person in charge as the main body, full-time quality inspectors, foremen, and construction teams. The quality management and control network system composed of inspectors, team leaders and part-time quality inspectors reasonably allocates quality functions at the construction site, improves and implements various management systems, and forms an execution mechanism with clear division of labor and clear responsibilities. In the actual implementation of program documents, we must adhere to the system first for each process, control it, and then check and accept it. We must strengthen control, strictly enforce quality discipline, effectively use quality veto power, strictly control project quality, and check every step, step by step. Inspect and eliminate project quality problems during the construction process.

4. Micro-management, stick to the front line

On-site quality work is complicated and intricate. A slight negligence will lead to big mistakes, so it is necessary to engage in on-site quality management work. Pay attention to every detail, highlight micro-management, and do everything personally. Before each process, you must learn what you have learned, study what is described in the book, list the operational difficulties and key points, and deeply understand it, and do it when explaining. Tell everything you know and talk about it, and provide technical training to operators for some key special processes (such as: steel bar welding, basement waterproofing, pumping concrete construction, roof waterproofing, etc.); in order to prevent workers from operating errors and management loss, on-site response Carry out round-the-clock tracking and control and provide comprehensive on-site guidance; set up full-time quality inspectors on-site to deal with problems immediately and eliminate quality hazards in a timely manner.

5. Details determine success or failure, comprehensive quality control

In the decoration and decoration construction stage, there are often multiple types of work and all-round cross-cutting operations, which is a construction stage with greater management difficulty. As the saying goes, "Decoration (decoration) depends on whether it is good or bad", which means that the construction quality in the decoration stage is crucial to achieving the overall quality target of the project. At this stage, in addition to the careful organization and careful construction of each sub-project, the focus of management should be on the reasonable arrangement of cross-cutting operations, and the attention to detail processing and finished product protection. Reasonably arrange cross-over tasks.

Detail processing and finished product protection are the keys to ensuring the final quality of decoration. The so-called "detail processing" is a common saying, which contains two meanings: "Details" generally refers to small parts outside of large-scale construction, the joints of various sub-projects, and the junctions of different materials and different methods. For example: the intersection of the wall, floor, and ceiling (yin-yang angle); the intersection of the skirting line with the wall and the ground; around the openings of doors and windows; around embedded pipes, cards, gold, and reserved holes; cornices and dripping water on outdoor walls Lines, drip troughs, grating joints; around roof drains, flashing ends, etc. The quality of these parts is difficult to describe quantitatively in specifications and standards, and most of them are not specified. However, these parts are important parts that affect the visual quality, and are key parts that reflect the construction management level and operating technology. If done well, they can have a finishing touch on the quality of the entire project. The word "Disposal" indicates that there are generally no regulations on the design of these parts, and the requirements are not clear due to the lack of specifications. Appropriate disposal depends on the experience and technical level of the on-site construction managers and operators.

To deal with details well, firstly, we must do a good job in prevention and pre-control, that is, think about problems first and resolve conflicts first. For example: the indoor room floor and the corridor floor are made of different materials. When dealing with the intersection of the door, it is necessary to consider in advance the elevation, thickness, color, joint method and other issues when making the ground base layer, so that the transition can be seamless and natural in the end; 2. The first is to unify standards, unify tools, and unify methods, that is, the same methods must be consistent in different parts of a unit project; the third is to make work or carve it carefully.

For example, work such as plugging pipe holes and repairing reserved holes in walls must be carefully performed by workers with good skills and strong sense of responsibility; fourth, the focus must be on the intersection and final intersection of different sub-items, different materials, and different methods. Live process. As the saying goes, "basket weaving is all about closing the seams." The final handover process must not only ensure the quality of this process, but also make up for the shortcomings or defects in the previous processes, and play the role of "closing the seams."

The protection of finished products is particularly important in the decoration and construction stage. Measures and responsibilities must be formulated at the beginning, and cross-operation arrangements should be made that are conducive to the protection of finished products, to prevent mutual damage or contamination, and to reduce losses in renovation or rework. , to ensure the realization of project quality objectives. ;
