What major quality hazards should project managers pay attention to in quality management?

On how project managers ensure project quality. With the development of social productivity and the advancement of science and technology, the requirements for project management of construction projects are becoming increasingly standardized and systematic. Project cost, project progress, and project quality and Safety and other aspects have made a qualitative leap compared with the past. Currently, how to ensure the quality of engineering projects will become the biggest test faced by every project manager. "A century-old plan, quality first." As the general commander of project construction, the project manager is responsible for ensuring the quality of the project. To this end, we must establish credibility with quality, seek efficiency with management, and strengthen construction site management. To ensure the quality of engineering projects, the key is to ensure the quality control of engineering projects during construction operations. Since the construction of the project involves a wide range of areas, the construction process is an extremely complex and comprehensive process. In addition, the project location is fixed, the production flow is different, the structure types are different, as well as the quality requirements, the construction methods are different, the size is large, the integrity is strong, and the construction The quality of construction projects is more difficult to control than the quality of general industrial products due to its long cycle and large impact from natural conditions. Therefore, comprehensive management of the quality assurance system must be implemented: 1. Scientific management, establishing and improving various management systems. Formulating job responsibility systems and various rules and regulations is the primary task and important part of enterprise management. The project manager must pay attention to the establishment of the system, and must do a good job in supervision and implementation at the construction site. Based on the original rules and regulations and the actual situation of the construction site, he must establish a job responsibility system for various personnel and clarify the responsibilities of the construction site management personnel. Responsibilities shall be documented and posted in the construction site office for easy implementation. At the same time, the operation and maintenance system of various machines, electricity, tic-tac-toe frames, exterior wall scaffolding and other equipment is clarified. Special personnel are responsible and managed to ensure that all work is in place. The responsibilities are implemented. Taking the "Suifu Primary School" project as an example: Based on the actual conditions of the construction site, the engineering project department has established dispatching meetings, analysis meetings, clarification meetings and inspection and assessment systems, and established a data filing system. Strengthen plan management, according to the overall progress requirements, timely revise the plan according to the actual construction, realize the control of important nodes, and keep the plan management in the best state. A briefing system was established at the construction site to promptly notify all parties of the project status, and a summary system was established, thus greatly strengthening on-site construction management and winning unanimous praise from all parties. 2. Raise awareness and strengthen the management of front-line workers. To improve the level of construction management, we must lead in thinking, that is, we must first improve management awareness. The core issue of enterprises is management. Due to the high mobility of production workers, generally poor technical quality and weak quality awareness, they only focus on work progress and ignore the scale and quality of the project. They are greedy for convenience, blindly seek speed, have low responsibility, and have poor safety awareness, which has brought great consequences to construction management. Difficulty, these awareness and practices must be completely changed. On the basis of improving the awareness of management personnel, project managers must also strengthen management of production workers. The specific approach is to implement the principle of “one choice, two education, and three management”. The first choice is to implement the principle of "survival of the fittest" for production workers, and those production workers with poor safety awareness, low technical quality, and disobedience to management must be eliminated. The second level of education means that workers must carry out "third-level education" before taking up their jobs. They must make various safety technical briefings before entering the workplace and obtain safety technical visas. A system of clear rewards and punishments must be implemented for workers in each construction team to fully mobilize the enthusiasm of workers and give full play to their leading role. Pre-job training is also required for operators of various types of work and major parts of each project. Three management means that all technical explanations must be made to production workers before construction, each process must be strictly controlled during the construction process, tracking, supervision, recording, review or spot inspection must be carried out, and everything from technical measures to actual operation must be strictly controlled. Quality is the key. Adhere to the combination of self-inspection, mutual inspection, and random inspection; adhere to the specific practice of not flowing into the next process if the previous process is unqualified, especially carry out full-time tracking and construction of work types and processes that are prone to common quality defects, and use mandatory means to restrain common quality defects. Change irregular practices. 3. Organize construction and strive to do a good job in project quality and safety management. When directing various projects, project managers must conscientiously do a good job in project quality and safety management. They must organize many units at a construction site to carry out construction in a rhythmic and balanced manner so that It achieves the effects of short construction period, good quality, safety and low cost. This is a very complex issue, which includes various management tasks such as technology, quality, safety, materials, progress and construction site. Therefore, in construction management, it is necessary to implement institutionalization and networking, rationalize the company's management system, and institutionalize various managements.

The project manager should regularly organize and hold professional business analysis meetings, and reflect the conclusions and information of various professional business analyzes to the company in a timely manner, so as to better achieve comprehensive control of the on-site construction process. In the management of the project, we must strictly follow the policy of "three inspections, two insistences, and one excellence" (that is, self-inspection, mutual inspection, and re-inspection; insist on construction according to the drawings, insist on construction according to the specifications; insist on construction according to the specifications; and ensure that the products are excellent). In construction, the responsibility is assigned to the people and the ideas are in place. In terms of quality management, we adopt the approach of overcoming common problems, creating excellence, and improving the quality of our products to ensure high-quality products, eliminate potential quality hazards in the bud during the construction process, and conduct acceptance inspections for each process to improve the first-time survival rate of our products. Strive to achieve a project quality rate of over 80%. We strive to overcome and eliminate common problems such as "seepage, leakage, shelling, cracking, pouring, roughness, blockage, and dirt" in the project, and strive to improve the quality of the project through management systems and ensure the quality of the project through technical measures. In terms of safety management, it is necessary to strengthen safety education and improve the safety awareness of employees and migrant workers. The company must be willing to spend manpower, material resources, and financial resources to improve safety facilities, and construction management personnel must perform their duties. During the construction of Suifu Primary School, we especially strengthened the education and protection work of the "Three Treasures and Four Ports", and supported the practice of gantry and scaffolding being delivered for use only after they have been inspected and accepted in sections. A volunteer fire brigade is organized and under the direct command of the project manager. Safety warning signs and safety slogans can be seen everywhere on the construction site, with the purpose of mobilizing safety to ensure safe production. In terms of technical data management, a dedicated person responsible for the project is assigned to fill in the construction diary and record the daily construction conditions in detail to facilitate contact before and after the project. All kinds of construction technical data and project progress are carried out simultaneously and organized by category, and put into data bags respectively, laying the foundation for accurate, fast and complete completion acceptance data. 4. Grasp construction market information and strengthen project cost control. Modern scientific management methods are changing with each passing day. Project managers must fully understand and understand new materials and new developments in domestic and foreign construction markets. First, based on the construction drawings, we conduct work and material analysis and conduct a large number of market surveys to prevent the use of substandard products. If the quality of materials does not meet the requirements, the quality of the project will not meet the standards. Therefore, strengthening the quality control of materials is an important guarantee for improving project quality and a prerequisite for creating normal construction conditions. The project manager must understand the market conditions of materials, as well as information on material quality, price, supply capacity, etc., supervise material procurement, open up material purchase channels, conduct comparison shopping, and try to purchase goods directly from manufacturers to minimize the middleman. In each link, we scientifically organize the procurement, processing, transportation, and storage of materials, establish a strict planning and scheduling system, implement unified adjustments of materials between projects, and accelerate the turnover of materials and funds to ensure normal construction. The main materials of the project must have formal factory certificates and inspection reports before entering the site. Reinforced concrete and prestressed concrete components shall be subject to sampling inspection in accordance with regulations. Component quality problems that arise due to transportation, installation, etc. should be analyzed and studied, and can only be used after being processed and signed. Any products or components that are unclearly marked or considered to have quality problems, or general materials that have doubts about the quality assurance information or are inconsistent with the contract provisions, etc., should be subject to material sampling inspection. For imported materials, equipment or materials used in key parts, such as concrete, mortar, waterproof materials, anti-corrosion materials, etc., the mix ratio of the materials should be ensured, and the test mix should be done according to regulations first, and can only be used after passing the test in the laboratory. In short, material control is the basis and prerequisite for quality assurance. 5. Take measures to protect construction machinery. Machinery control includes construction machinery and equipment and tool cost control. Appropriate mechanical equipment should be selected according to different process characteristics and technical requirements. Correctly use, manage and maintain mechanical equipment. To this end, it is necessary to improve the "man-machine fixation system", "operation certificate system", "job responsibility system", "safe use system", "shift handover system", etc. to ensure that mechanical equipment In optimal used condition. During the construction of the "Suifu Primary School" project, the company used simple and practical "star tiles" as the canopy roof to protect machinery. Various mechanical equipment at the construction site, such as mortar machines and other machinery, were all installed in one machine. One cap, each with a number. Since the roof of the rainproof shed is made of star tiles, the frame is made of 1-inch steel pipes and accessories. The star tiles and the frame are bound with iron wires, which is more convenient for installation, disassembly and use. It is both beautiful and practical, and can It is used for multiple turnovers, has good visibility during construction, takes up little space on the construction site, is rainproof and windproof, and ensures safe production.

6. Strengthen the control of the construction process and improve the quality of the project. Excellent project quality is directly produced in the construction process. The project department construction workers and quality safety officers must inspect the construction operation process of the work team, including operating methods, work procedures, etc. at all times. and supervision to nip quality problems in the bud as much as possible. When entering the rough decoration stage of civil engineering, before the team leader enters the site, he should be required to make a sample or sample wall. Only after the sample acceptance reaches the expected effect can the large-scale construction be officially started. In the future, the acceptance of the team's work quality will be based on his own opinions. The sample made serves as the actual standard. Before entering the masonry of the main project, the construction unit should be asked to determine the variety and specifications of the exterior wall facing bricks as soon as possible, so that the aluminum window openings can be located according to the size and size of the facing bricks calculated and positioned during the masonry work. At the same time, the construction sequence of exterior wall finishes can be adjusted according to construction requirements. We also assisted the team in carrying out sample construction on the first-floor exterior wall to ensure that the facing tiles were laid in a regular pattern, the window sills had a uniform slope, the eagle nozzles had consistent specifications, and the lines and seams were straight and horizontal, thus improving the quality of the project. 7. Do a good job in civilized construction and fully realize standard construction. With the improvement of urban modernization, the requirements for civilized construction are becoming higher and higher. Therefore, whether in the bidding, bidding stage, or in the construction implementation stage, civilized construction measures have become very important in the construction technical plan and construction organization design. To this end, the task of building a civilized construction site is seriously placed in front of every project manager. Building a civilized construction site is a series of projects for enterprises to continuously improve their comprehensive capabilities and overall level and adapt to the needs of the market economy. Building a civilized construction site and organizing construction according to modernization and standardization requirements is to shape the "window" image of the enterprise, which is conducive to controlling resource consumption, reducing the frequency of accidents, eliminating hidden dangers of accidents, and gaining more social benefits and early economic benefits. Therefore, when organizing the construction process, the project manager should put civilized construction in an important position, pay close attention to the work of building a civilized construction site, implement it, and organize and establish a construction site civilized leadership group to form a strict management network with the company. In order to achieve from vertical to horizontal, from block to strip, block to block guarantee, block to block implementation, proceed from the overall situation, and carry out civilized construction on the construction site through multiple channels. Take Suifu Primary School as an example: The entire construction site must be laid out in strict accordance with the approved construction organization design. A simple and regular gate is set up at the entrance and exit of the construction site. The name of the project and the contractor are clearly marked on the door frame, and there are inlays on both sides of the door frame. The slogan "Quality is the life of an enterprise, safety is the benefit of an enterprise". The construction site is fully enclosed for construction. The construction site is flat and clean. All roads are hardened and solid and smooth. Water slopes are poured around the buildings. The surroundings are kept clean. The drainage of the site is systematic and unobstructed. Construction waste is piled up in a centralized manner and transported away in time. The on-site office is clean and tidy, with various management systems, job responsibility systems and target management responsibility systems. The list of quality and safety leadership groups is posted on the wall, making it clear at a glance. All employees have goals and everyone has assessments. Building materials are neatly stacked according to categories, specifications, and varieties, such as: sand and gravel are classified and stacked into squares; masonry materials are classified into stacks and stacked neatly, and broken bricks are cleared as needed; ash pool masonry meets standards and is reasonably laid out , safe and clean. Construction turnover facilities and equipment, large formwork, etc. are stacked in a centralized manner, and the formwork is placed stably in pairs with correct angles. Bamboo and wood miscellaneous materials are piled up in categories and in square format, not scattered or messy. There is a special cement warehouse on site. The cement is clearly labeled and stacked neatly. There are systems and regulations in place. It is managed by dedicated personnel. It is distributed in quotas and is classified and labeled. The records are complete and correct. The storage capacity is clean and tidy, and there is no "leakage from top to bottom". ". The construction site is equipped with tea kiosks and tea buckets with lids and cups, disinfection equipment, and a dedicated smoking area. When work is completed every day, a dedicated person will check the civilized construction status of each team. It is truly done that the feet are clean after the work is completed, and the site is clean after the work is completed. The entire site is clean during the completion acceptance, showing it in front of people with a brand-new look, and has won the trust of all units. Good reviews. As market competition becomes increasingly fierce, project managers must clearly realize that there is still a large gap between their work and the standards of building regulations, and they must conscientiously and seriously continue to improve in their daily work. "Sail against the current, if you don't advance, you will retreat." We can only continuously improve our own quality and technical level, apply the IS09002 international standard quality system management model, scientifically implement comprehensive management of the process, continue to summarize, and continuously improve.
