Purpose: The construction industry is a high-risk sector characterized by complex processes and multiple stakeholders. While smart construction technologies are increasingly adopted, empirical evidence explaining how technology characteristics and acceptance factors translate into safety performance remains limited. This study aims to conceptualize smart construction technology as a system of technology characteristics and to empirically examine its impact on safety performance through technology acceptance mechanisms. Method: An integrated analytical framework combining the Technology Acceptance Model (TAM) and Task–Technology Fit (TTF) theory was developed. Survey data collected from construction site practitioners were analyzed using structural equation modeling (SEM). Result: The results show that one dimension of task–technology fit (TTF2) has a significant positive effect on smart construction technology characteristics (β = 0.457), whereas another dimension (TTF1) has a significant negative effect (β = -0.494). In contrast, technology characteristics exert a strong direct influence on safety performance (β = 0.924), while the mediating effects of technology acceptance factors are relatively limited. Conclusion: These findings indicate that improvements in construction safety performance depend more on the practical implementation level of smart construction technology characteristics—such as integration and automation—than on changes in user perceptions alone.
