| Abstract |
In contrast to practices in other countries, the domestic construction industry continues to delegate certain projects won by the primary contractor to subcontractors. To address concerns regarding overly complex business structures, a direct construction mandatory system was introduced. However, there remains a lack of comprehensive quantitative research on its actual effects on construction site management. Given that half of all industrial accidents occur in the construction sector, emphasizing effective management is paramount. Hence, this study investigates the impact of the direct construction mandatory system on construction site management through PLS-SEM analysis. Initially, via a review of prior studies and focus group interviews (FGI), factors contributing to poor management and anticipated positive/negative outcomes of system implementation were identified. Subsequently, a survey was administered to construction industry workers to evaluate the extent of influence of these factors, followed by PLS-SEM analysis based on the survey results. The findings reveal that the direct construction mandatory system enhances environmental and safety management but leads to increased initial investment and management costs. To optimize the system's effectiveness, strategies to alleviate additional cost burdens should be prioritized. Additionally, the system's impact on mitigating worker negligence was found to be minimal. To address this and reduce construction accidents, measures to enhance worker satisfaction, such as implementing a unified wage system across all construction projects, should be considered as primary interventions. |
