| Abstract |
This study empirically analyzed the differences in disaster prevention technical guidance working conditions and effectiveness between public and private construction projects, based on a survey of 76 technical guidance practitioners who hold industrial safety consultant licenses and perform technical guidance at disaster prevention specialized agencies. The questionnaire consisted of 11 items across four categories, and the same respondents evaluated both public and private sites. The data were analyzed using reliability analysis, exploratory factor analysis, paired t-test, and relative priority analysis based on Thurstone’s Law of Comparative Judgment. Public projects scored significantly higher than private projects across all four categories (p<.001), with the largest difference in client and site acceptability. In the priority analysis, communication with site personnel ranked first in both types. However, client interest fell from second in public to fifth in private, while implementation of guidance results rose from fifth to second, confirming that the most critical factors differ by project delivery type. These findings can serve as foundational data for strengthening client responsibility in private projects and developing differentiated guidance approaches. |
