With the development of social productivity and advancements in science and technology, the requirements for project management in construction projects have become increasingly standardized and systematic. There has been a qualitative leap in aspects such as project costs, schedule, quality, and safety compared to the past. Currently, ensuring the quality of engineering projects has become the greatest challenge for every project manager. “For a project that lasts a century, quality comes first.” As the overall commander of a project’s construction, the project manager bears the important responsibility of ensuring the quality of the project. To this end, it is necessary to build credibility through quality, seek efficiency through management, and strengthen site management. To ensure the quality of construction projects, the key lies in maintaining quality control during the construction process. Given that construction projects involve a wide range of aspects, their construction process is an extremely complex integrated one. Moreover, factors such as fixed project locations, mobile production processes, various structural types, different quality requirements and construction methods, large scale, high integrity, long construction periods, and significant influence from natural conditions make it even more difficult to control the quality of construction projects compared to that of ordinary industrial products. Therefore, comprehensive management of a quality assurance system is essential: 1. Scientific management – establishing sound management systems. Formulating job responsibility systems and various rules and regulations is a primary task and an important aspect of enterprise management. Project managers must pay attention to the establishment of systems; at the construction site, they need to ensure proper supervision and implementation. Based on existing rules and regulations, and taking into account the specific conditions of the site, they should establish job responsibility systems for all personnel, clarify the duties of site management staff, and post these documents in the site office for reference and compliance. At the same time, clear operating and maintenance procedures are established for various equipment such as machinery, electrical systems, derricks, and exterior wall scaffolding; these are handled by designated personnel to ensure that all tasks are carried out properly, with responsibilities clearly assigned. Taking the “Sui Fu Primary School” project as an example, the project management team established systems for scheduling meetings, analysis sessions, briefings, and inspections and evaluations, in addition to a document archiving system. Strengthen plan management; in accordance with the overall schedule requirements, adjust the plans promptly based on the actual construction progress, thereby ensuring control over key milestones and keeping plan management in its optimal state. A briefing system was established at the construction site to keep all parties informed of the progress of the project, and a summary system was put in place, thereby **strengthening on-site construction management and earning unanimous praise from all parties. 2 Raise awareness and strengthen the management of front-line workers. To improve construction management levels, it is necessary to lead with a forward-thinking approach, that is, to first enhance management awareness. The core issue for a company is management. Due to the high turnover rate of production workers, their generally poor technical skills, weak quality awareness, focus solely on work progress while ignoring project scale and quality, a tendency to seek convenience and haste, lack of responsibility, and poor safety awareness, construction management faces significant difficulties; these attitudes and practices need to be completely changed. On top of raising the awareness of management staff, the project manager must also strengthen supervision over production workers. The specific approach is to implement the principle of “one selection, two educations, three managements”. Once this option is chosen, the principle of \"survival of the fittest\" is applied to production workers; those with poor safety awareness, low technical skills, and who do not obey management must be eliminated. Second, education involves implementing a \"three-level training\" program for workers before they start working; it also entails providing all necessary safety and technical instructions prior to their entry on site, as well as issuing relevant safety and technical certifications. A system with clear rewards and penalties must be implemented for the workers in various construction teams, in order to fully motivate them and leverage their proactive role. Pre-job training should also be provided for operators in various job types and at the key sections of different projects. The three aspects of management involve ensuring that all necessary technical instructions are provided to the workers before construction begins; strictly controlling each stage of the construction process through tracking, supervision, recording, reinspection, or random checks; and maintaining strict quality control from technical measures to actual operations. Adhere to a combination of self-inspection, mutual inspection, and random inspection ； Adhere to the principle that work from a previous process shall not proceed to the next stage unless it is qualified; in particular, carry out dedicated supervision of those tasks and processes where quality issues tend to occur, using mandatory measures to curb such problems and eliminate irregular practices. 3. Organize construction activities and strive to ensure effective management of project quality and safety. When directing various construction tasks, the project manager must pay close attention to quality and safety management. It is necessary to coordinate the efforts of many entities at a construction site to carry out work in a systematic and balanced manner, so as to achieve results such as short completion times, high quality, safety, and low costs. This is a complex task that involves various aspects of management, including technology, quality, safety, materials, schedule, and the construction site itself. Therefore, in construction management, it is necessary to implement institutionalization and networking, streamline the company’s management systems, and ensure that all aspects of management are institutionalized. The project manager should regularly organize professional business analysis meetings, and ensure that the conclusions and information derived from such analyses are promptly communicated to the company, thereby enabling better overall control over the on-site construction process. In project management, it is necessary to strictly adhere to the principle of “three inspections, two persistences, and one excellence” (namely, self-inspection, mutual inspection, and re-inspection) ； Adhere to construction in accordance with the plans, and follow the relevant specifications ； Construction is carried out in accordance with the principle of high-quality products, with clear labeling, assigned responsibilities, and a strong commitment from all involved. Quality management focuses on addressing common problems, striving for excellence, and raising standards, thereby ensuring high product quality. Potential quality issues are eliminated at the earliest stages of the manufacturing process, and each stage of production is inspected to improve the success rate of the final product. Strive to achieve an excellent project quality rate of over 80%. Strive to overcome and eliminate common engineering problems such as seepage, leakage, cracking, collapse, roughness, uneven surfaces, blockages, and contamination. Aim to improve project quality through management systems and ensure it through technical measures. In terms of safety management, it is necessary to strengthen safety education in order to raise the safety awareness among employees and migrant workers. The company must be willing to invest manpower, resources, and funds in improving safety facilities, and construction management personnel must fulfill their duties responsibly. During the construction at Sui Fu Primary School, special emphasis was placed on education and protection measures related to the \"three treasures and four openings.\" It was required that scaffolding and staging be approved in stages before they could be put into use. An organized fire brigade is established and directly commanded by the project manager. Safety warning signs and slogans can be seen everywhere at the construction site, with the aim of motivating everyone to ensure safe production. In terms of technical document management, a dedicated person is assigned to the project to keep a construction diary, detailing the daily progress of work to facilitate communication before and after the project. All types of construction technical documents are organized by category alongside the project progress, and placed in separate document bags, thereby laying the foundation for ensuring that the documents required for completion inspection are accurate, available promptly, and complete. 4. Keep track of construction market information and strengthen project cost control. Modern scientific management methods are evolving constantly, and project managers must be fully aware of the new materials and developments in domestic and international construction markets. First, based on the construction drawings, a material analysis is carried out, along with extensive market research, to prevent the use of substandard products. If the quality of the materials does not meet the requirements, then the quality of the construction work cannot meet the standards either. Therefore, strengthening quality control of materials is an important guarantee for improving project quality and a prerequisite for creating normal construction conditions. Project managers must be familiar with market conditions for materials, as well as information regarding their quality, price, and supply capabilities. They need to oversee the procurement of materials, explore various sources for obtaining them, compare different options, and strive to purchase materials directly from manufacturers in order to minimize intermediate steps. It is also necessary to organize the procurement, processing, transportation, and storage of materials in a systematic manner, establish a robust planning and scheduling system, facilitate the unified allocation of materials across different projects, and accelerate the turnover of funds related to materials, all in order to ensure smooth construction progress. For the main materials used in the project, official factory certification and inspection reports must be provided upon arrival. Reinforced concrete and prestressed concrete members shall be subject to sampling inspections in accordance with regulations. Quality issues of components arising from reasons such as transportation and installation should be analyzed and studied; they can only be used after proper handling and signing off. Products or components with unclear markings or suspected quality issues, as well as general materials for which there are doubts regarding the quality assurance documents or that do not conform to the contract specifications, should all be subject to random material inspections. For imported materials, equipment, or materials used in critical components such as concrete, mortar, waterproofing materials, and anti-corrosion materials, it is necessary to ensure the correct mix ratio of these materials. Trial mixing must be carried out in accordance with relevant regulations, and the materials can only be used after passing the tests conducted in the laboratory. In short, material control is the foundation and prerequisite for ensuring quality. 5 Take measures to ensure proper protection for construction machinery; the control of machinery includes the management of construction equipment and tools. Appropriate mechanical equipment should be selected based on the different process characteristics and technical requirements. Mechanical equipment should be used, managed, and maintained properly; to this end, systems such as a \"person-machine pairing system,\" an \"operating license system,\" a \"post responsibility system,\" a \"safe use system,\" and a \"shift handover system\" must be established to ensure that the equipment is in optimal working condition. During the construction of the \"Sui Fu Primary School\" project, the company used the simple and practical \"Xingwa\" shelter roofs to protect the machinery. For all the mechanical equipment at the site, such as mortar mixers, a separate shelter was provided for each piece of equipment, with each one assigned a unique identifier. Since the roof of the rain shelter is made of star-shaped tiles, its framework is constructed using 1-inch steel pipes connected with various fittings; the star-shaped tiles are tied to the framework with iron wires. This design makes installation, removal, and use convenient. It is both aesthetically pleasing and practical, and can be reused multiple times. It provides good visibility during construction, occupies little space on the construction site, and protects against both rain and wind, thus ensuring safe production. 6 Strengthen control during the construction process to improve project quality. Excellent project quality arises directly from the construction process; therefore, the construction supervisors and quality and safety officers in the project team must constantly monitor and inspect the construction activities of the work teams, including the methods used and the work procedures, in order to eliminate quality issues at their earliest stages. Before entering the stage of rough civil engineering work and before the team leader arrives, it is necessary to have a sample or sample wall created first; only after the sample meets the desired standards can the actual construction begin on a larger scale. Going forward, the quality of the team’s work will be assessed using this sample as the standard. Before starting the masonry work for the main structure, the construction owner should be asked as soon as possible to decide on the type and specifications of the exterior wall tiles, so that the dimensions of these tiles can be used to calculate and mark the positions during masonry, thereby determining the locations of the aluminum window openings. At the same time, the construction sequence of the exterior wall finish can be adjusted according to the construction requirements. It also assists the team in carrying out sample construction on the exterior wall on the first floor, to ensure that the decorative tiles are laid neatly, the slope of the window sills is consistent, the specifications of various elements are uniform, and the lines and joints are straight and aligned, thereby improving the quality of the project. 7 Ensure civilized construction and fully achieve standard construction practices. As cities become more modern, the requirements for civilized construction in building projects also increase. Therefore, whether during the bidding or tendering phase or during the construction implementation phase, measures for civilized construction become extremely important in the construction technical plan and construction organization design. To this end, the task of creating civilized construction sites lies seriously before every project manager; building such sites is part of a series of efforts by enterprises to continuously improve their comprehensive capabilities and overall standards in order to meet the demands of the market economy. Constructing civilized construction sites by organizing work in accordance with modern and standardized requirements helps to shape the company’s image as a \"window\" to the public; it facilitates control of resource consumption, reduces the frequency of accidents, eliminates potential accident risks, and brings about various social benefits as well as economic advantages. Therefore, during the construction process, project managers should give high priority to civilized construction, make serious efforts to ensure that the work of creating a civilized construction site is carried out thoroughly and effectively. They should also establish a leadership team for civilized construction at the site, thereby forming a robust management framework in conjunction with the company. This approach allows for comprehensive management, with measures implemented both vertically and horizontally, ensuring that all aspects are covered and that actions are taken in an organized manner, thus enabling the successful implementation of civilized construction practices through various channels. Taking Suifu Primary School as an example: the entire construction site must be laid out in strict accordance with the approved construction plan. A simple and orderly gate has been installed at the entrance and exit of the site, with the project name and the contracting company clearly indicated on the gate frame; moreover, slogans reading “Quality is the life of a company, safety is the profit of a company” are engraved on either side of the gate frame. The construction site is fully enclosed; the area is leveled and kept tidy, with all roads paved to ensure they are solid and passable. Slopes for draining water are built around the buildings, and the surrounding area is kept clean. The drainage system on the site is well-designed and unobstructed. Construction waste is piled up in a centralized area and removed promptly. The on-site office is clean and tidy; various management systems, job responsibility frameworks, as well as target management systems, along with the list of members of the quality and safety leadership team, are all posted on the walls for easy reference. This ensures that everyone has clear goals and is subject to evaluation. Building materials are neatly stacked by category, specification, and type; for example, sand and gravel are sorted and piled up in organized piles ； Masonry materials should be grouped into stacks and placed neatly; broken bricks should be cleared as they are used ； The construction of the ash pond meets the standards, with a rational layout that is safe and tidy. Construction temporary facilities and equipment, as well as large formwork, are stored in a centralized manner; the formwork is placed steadily in pairs at the correct angle. Bamboo and wood scraps are stacked in categories, arranged in neat blocks, keeping them organized and tidy. There are dedicated cement storage areas on site; the cement is sorted by grade and stored neatly, in quantities that can be easily counted. There are established systems and regulations, with dedicated personnel in charge of managing it. Distribution is carried out within set limits, and the cement is labeled and categorized appropriately. Records are kept thoroughly and accurately, and the storage areas are kept clean, without any signs of leakage. The construction site is equipped with tea kiosks and tea dispensers, including lids and cups, as well as disinfection equipment and a designated smoking area. At the end of each day, a dedicated person checks the level of civilized construction in each work team, ensuring that the work area is cleaned up after each task is completed. By the time of completion inspection, the entire site is spotless, presenting itself in a fresh state and earning praise from all the relevant parties. As market competition becomes increasingly fierce, project managers must be aware that there is still a significant gap between their work and the standards set by building codes, and they must diligently and seriously strive for continuous improvement in their daily tasks. “\"One must row against the current; if one does not move forward, one will fall back.\" Only by continuously improving one’s own capabilities and technical skills, by adopting the quality management system framework of ISO9002, by implementing comprehensive process management in a scientific manner, and by constantly summarizing experiences to achieve further improvement, can progress be made.
