건설산업재해 저감을 위한 직접시공의무제도와 건설 현장관리의 영향관계 분석

In contrast to practices in other countries, the domestic construction industry continues to delegate certain projects won by the primarycontractor to subcontractors. To address concerns regarding overly complex business structures, a direct construction mandatory system wasintroduced. However, there remains a lack of comprehensive quantitative research on its actual effects on construction site management. Giventhat half of all industrial accidents occur in the construction sector, emphasizing effective management is paramount. Hence, this studyinvestigates the impact of the direct construction mandatory system on construction site management through PLS-SEM analysis. Initially, viaa review of prior studies and focus group interviews (FGI), factors contributing to poor management and anticipated positive/negativeoutcomes of system implementation were identified. Subsequently, a survey was administered to construction industry workers to evaluate theextent of influence of these factors, followed by PLS-SEM analysis based on the survey results. The findings reveal that the directconstruction 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 impacton mitigating worker negligence was found to be minimal. To address this and reduce construction accidents, measures to enhance workersatisfaction, such as implementing a unified wage system across all construction projects, should be considered as primary interventions.
