The structural equation model of risk factors influencing government irrigation project

Abstract This research aimed to study the impact of risk factors on the success of irrigation projects in Thailand. Data were collected using questionnaires at irrigation agencies in various projects. A structural equation model (SEM) was then developed, and the risks of various factors affecting the irrigation project were analysed. The study results found that the risk factors affecting the construction process were as follows: The study results found that the risk factors affecting the construction process were as follows: In terms of work control, the presence of multiple chains of command led to delays in decision-making. This was followed by delays caused by the employer’s material approval process, the lack of clear and detailed construction project planning by the employer, and delays resulting from the performance of subcontractors. The factors mentioned above resulted in the highest score of all 56 factors. The findings of this study showed factors that affected the project, causing project managers, related agencies, or stakeholders to know and find a way for problem solution. The results of this study have found that the SEM values of risk management affecting the construction irrigation project have passed the criteria and have caused the relationship. Those values consist of significance chi-square ( p -value = 0.799), chi-square relation value at 0.413, normal fit index (NFI) value at 0.999, goodness of fit index (GFI) value at 0.999, CFI value at 0.999, standardised root mean square residual (RMR) value at 0.029, and root mean square error of approximation (RMSEA) value at 0.001.
