A Systematic Literature Review for Identifying Risk Factors in Storage Tank Construction Projects

Expert Validation Using Aiken’s V Method

Abstract

This study aims to identify and validate critical risk factors in storage tank construction projects through a systematic literature review (SLR) and expert judgment using Aiken’s V method. 103 scientific journal articles were initially selected based on their relevance to storage tank construction risks. Following a rigorous screening process, 43 articles were deemed relevant and analyzed in detail. These articles synthesized 33 causal factors and six key risk factors, forming a preliminary model of risk factors. To validate the relevance of the identified factors, expert evaluation was conducted involving eight professionals with substantial experience in storage tank construction projects. The results of Aiken’s V analysis indicated that 13 causal factors and four key risk factors achieved a validity coefficient above the acceptable threshold, confirming their suitability for inclusion in further risk modeling processes. The findings of this study provide a solid foundation for future research in quantitative risk analysis, such as Bayesian Belief Network modeling, and offer practical insights for risk mitigation planning in storage tank construction projects Estimation, Flexible Pavement, Life-Cycle Cost, Pavement Design.
