The Research On Construction Quality Problems Influence Of The Major Participants Of Construction Projects

With the rapid development of China’s economic construction and urbanization, the number of construction projects has a sharp increase. However, there are also many construction quality problems in the process of construction projects, such as the common construction quality problems plaster hollowing and peeling, concrete burst mode, cast-in-place plate, toilet’s leaking, underground waterproofing problems even serious quality accidents some time happen for beams cracking, building collapse. It not only causes great potential security problems which damage the property of country and people but also can’t promote the healthy development of the construction industry and can’t meet people’s higher requirements for the construction quality. Because of these characteristics of construction projects, such as the participation of multi-subjects, the great investment, the long cycle of construction, the projects of temporality or stationarity, and the project environment of complexity and uncertainty, a variety of quality problems appear in the construction of engineering projects. Even it will affect the progress and the cost of the construction project. This paper respectively analyzes the problems which affect the projects quality by the owner, the contractor and supervision unit that the main three players have the most direct influence on the construction project. Then it founds out the key factors of affecting the construction quality problems and compares them. At last, this paper puts forward the measures and suggestions about to prevent construction quality problems which not only further improves the theories and methods of construction quality management in theory, but also has extremely important practical significance on improving construction quality.This paper has a classification analysis about the influence factors of engineering quality problems by the study of literature. Although the major participants are partners in the construction project, its benefit, the responsibility of the quality control and the causes of construction quality problems are different. Therefore, this paper respectively summarizes the influence factors of construction quality problems about the owner, the contractor and supervision unit according to the principle of WBS. Then it further modifies and improves the influence factors sheets of the construction quality problems about the major participants through the methods of expert interview. Next, according to the research demands, this paper respectively builds the model of principal component analysis about the influence factors of construction quality problems related to the owner, the contractor and supervision unit, and gets the data which is the importance of quality problem’s influence factors impacting on the construction quality. At last, with the help of SPSS software, it calculates the main influence factors of the construction quality, explains and renames them.This paper puts forward the measures and suggestions corresponding to prevent construction quality problems on the basis of the main influence factors about the major participants’ construction quality problems and by the comparison among the factors. The research of this paper not only further perfects the theories and methods of construction quality management, but also puts forward the measures and suggestions to guarantee and improve construction quality.
