Analysis of affecting factors on the quality of construction of hydraulic structures: a case study in Hau Giang province

Abstract

The objective of this study is to analyze the factors affecting the quality of construction of hydraulic structures in Hau Giang province. To achieve the above objective, the following steps were taken: (1) To collect and compile data to preliminarily determine the most likely affecting factors; (2) to interview related experts to assess the suitability of the affecting factors under the characteristics of the research area; (3) to survey related stakeholders to assess the affecting levels (based on a 5-point Likert scale) by analyzing Cronbach's Alpha reliability, Exploratory Factor Analysis (EFA), correlation, and linear regression. The results show that from 29 factors belonging to five initial groups (stakeholders during construction, construction process at the site, materials, design, and external impacts), the research points out four groups of factors that affect construction quality under different affecting levels (for the groups and their individual factors). Based on this, the corresponding solutions are proposed to improve the quality of construction of hydraulic structures in Hau Giang province.
