The Project Construction Quality Management And Control

Construction industry has become the foundational industry of our society. As the products of building engineering, construction object will need large numbers of money, labour force, materials and energy. Investors want to acquire top-quality and usable construction product by their investment, which can also provide profits to construction unit. And it is crucial to get the qualified product constructed without any letup. Therefore, the quality management of construction object is chosen as this research object, and it is important and meaningful for the whoie process of construction object. The quality of construction ensures the producing and life of society and the subsistence and development of building firm, which is also the foundation of getting benefits.In this paper, first, the quality management was defined, the quality characteristic and quality management of the construction object was summarized, and the method of quality management was expatiated, which is called comprehensive quality management (CQM). Then, the character, concept frame and research method of comprehensive quality management (CQM) were stated. And the process, function, assignment, the systematic operation, criteria and monitoring methods of quality management were also stated in detail. Basing on the different implication of quality and construction object quality, the quality management in work progress was mainly discussed. The quality management in construction stage is a systematic control process, which includes the first quality control of resource and qualification, the next quality control of work progress, and find productionquality test. As the nature of engineering construction is a kind of producing, it is necessary to manage the five factors in the whole process, which also affect the quality of construction object. They include Man, Machine, Material, Method, Environment (5M).In this paper, the quality control method and the application of comprehensive quality management (CQM) in work progress of the house building of Chengdu-Nanchong freeway II and III were discussed detailedly. And in the operation, the quality control was applied in the aspects of 5M, and the results were analysed in the same aspects. In addition, the basal tools of quality control, including bar graph, control chart and case and effect diagram, were used to make qualitative analysis, evaluate and improve the quality of concrete of pouring girder at Daying station office building in Chengdu-Nanchong freeway. Consequently, the goal of better quality and more profits were achieved.
