Özet

The main goal of this study is to examine the relationships between determinants of safety performance of construction sites. To achieve this goal, 168 observable variables and 16 latent dimensions that affect safety performance of construction sites were collected through extensive literature reviews, expert opinions, and face-to-face interviews. A questionnaire form was developed and administered to construction professionals as a data-collection tool about the observable variables and latent dimensions. A total of 180 responses were achieved through data collection. Relationships between observable variables and latent dimensions of the safety performance of construction sites were studied and a multidimensional safety performance model was proposed. The proposed multidimensional safety performance model was supported by structural equation modeling (SEM) analysis. Moreover, 16 latent dimensions with respect to their relative weights and recommendations for construction safety professionals are provided to improve the safety performance of construction sites.
