The quality control in project management is mainly reflected in the quality control of construction organizations and construction sites. The contents include process quality control and product quality control. The factors affecting quality control mainly include humans, materials, machinery, methods, and the environment. Therefore, strict control of these five elements is the key to ensuring project quality.

5 Elements of Project Management Quality Control – Quality Control in Project Management

1. Human factors

Human factors mainly refer to the quality of leaders, the theoretical and technical level of operators, physiological defects, carelessness, violation of discipline and regulations, etc. During construction, the control of human factors should be considered first, because people are the main body of the construction process. The formation of project quality is jointly affected by all engineering technical cadres, operators, and service personnel participating in the construction of the project. They are the main factors forming project quality. First of all, their quality awareness should be improved. Construction personnel should establish the concept of quality first, the concept of pre-control first, the concept of serving users, the concept of speaking with data, and social benefits, enterprise benefit, and the concept of comprehensive benefits. Secondly, the quality of people. The quality of leaders and technicians is high. The decision-making ability is strong, so there is a strong ability of quality planning, target management, construction organization, technical guidance, and quality inspection; the management system is perfect, the technical measures are effective, and the project quality is high. The operators should have exquisite technical skills. meticulous work style and legal concept of strictly implementing quality standards and operating procedures; The service personnel shall provide technical and living services to indirectly ensure the project quality with the excellent work quality. To improve people’s quality, we can rely on the organic combination of quality education, spiritual and material incentives, as well as on-the-job technical training through training and optimization.

2. Material factors

Material Science (including raw materials, finished products, semi-finished products, components, and accessories) is the material conditions of project construction. Material quality is the basis of project quality. If the material quality does not meet the requirements, the project quality cannot meet the standards. Therefore, strengthening the quality control of materials is an important guarantee to improve the project quality. The factors affecting the material quality are mainly the composition, physical properties, and chemical properties of materials Key points of performance and material control include:
1) Select purchasing personnel, improve their political quality and quality appraisal level, and select those with certain professional knowledge. A man loyal to his career takes the job.
2) Master material information and select suppliers.
3) Reasonably organize material supply to ensure normal construction.
4) Strengthen the inspection and acceptance of materials and strictly control the quality.
5) Pay attention to the on-site management of materials and do a good job in rational use.
6) Do a good job in material tests and inspections. According to statistics, the cost of materials in construction projects accounts for 70% or more of the total investment. Because of this, some contractors get the project. In order to seek more benefits, relevant finished products or semi-finished products are not purchased according to the varieties, specifications and technical parameters required by the engineering technical specifications, or the quality of raw materials is not effectively controlled due to the low quality of purchasing personnel. Some enterprises do not have a perfect management mechanism and restraint mechanism, and can not prevent unqualified fake and shoddy products and raw materials from entering the project construction, leaving potential quality hazards to the project. Today, with the high development of science and technology, it provides a scientific method for the inspection of materials. The state has introduced it in detail in the relevant construction technical specifications. As long as we strictly implement it in the actual construction, we can ensure the quality of materials used in the construction.

3. Method factors

The methods in the construction process include the technical scheme, process flow, organization measures, detection means, construction organization design, etc. taken in the whole construction cycle. Whether the construction scheme is correct or not directly affects the smooth realization of project quality control. The progress is often delayed due to poor consideration of the construction scheme, affecting the quality and increasing the investment. Therefore, when formulating and reviewing the construction scheme, we must conduct a comprehensive analysis and comprehensive consideration from the aspects of technology, management, process, organization, operation, and economy in combination with the actual situation of the project, and strive to make the scheme technically feasible, economically reasonable, advanced process, effective measures, and convenient operation, which is conducive to improving quality, accelerating progress and reducing cost.

4. Mechanical equipment

In the construction stage, it is necessary to comprehensively consider the construction site conditions, building structure form, construction technology, and methods, building technology and economy, reasonably select the types and energy parameters of machinery, reasonably use mechanical equipment and operate correctly. Operators must carefully implement various rules and regulations, strictly abide by the operating procedures, and strengthen the repair, maintenance, and management of construction machinery.

5. Environmental factors

There are many environmental factors affecting the project quality, including engineering geology, hydrology, meteorology, noise, ventilation, vibration, lighting, pollution, etc. The impact of environmental factors on project quality is complex and changeable. For example, meteorological conditions change thousands of times. Temperature, humidity, strong wind, rainstorm, extreme heat, and severe cold all directly affect project quality. Often, the previous process is the environment of the next process, and the previous sub-item and the divisional project is the environment of the next sub-item and divisional project. Therefore, according to the project characteristics and specific conditions, effective measures shall be taken to strictly control the environmental factors affecting the quality. In addition, during construction in winter rainy season, hot season, and wind season, effective measures to ensure the construction quality seasonally shall be formulated according to the characteristics of the project, especially concrete works, earthworks, underwater works, and high-altitude operation, so as to avoid the harm of freezing damage, dry crack and scouring to the project quality. At the same time, it is necessary to continuously improve the environment of the construction site, minimize the harm caused by construction and environmental pollution, improve the construction site management system and implement civilized construction.
