Identification and analysis of influencing factors on construction quality management for rural drinking water safety project

Exploring the influencing factors of construction quality management is the key to ensuring the quality of rural drinking water safety projects. Based on the grounded theory, the influencing factors were identified and 65 relevant staff were selected by the objective sampling method for in-depth interviews to obtain the original data. In this study, 34 initial concepts, 18 main categories, and 5 core categories were collected and extracted for the rural drinking water project's safety engineering and construction quality management evaluation system. Furthermore, the incremental model of influencing factors on construction quality management performance of rural drinking water safety project was established by Decision-making Trial and Evaluation Laboratory-Interpretative Structural Modeling (DEMATEL-ISM) model. Through calculation and analysis, the key influencing factors of construction quality management performance of rural drinking water safety project were identified as controls on common quality problems, quality specification implementation, leadership level, acceptance management, design disclosure and modification, and human environment. Countermeasures and suggestions are proposed to improve the construction quality management performance of rural drinking water safety construction project.
