In addition to its risky nature, the construction industry incorporates a social interaction aspect as one of its qualities. The study presented in this paper aims to investigate the interaction properties that impact safety issues on jobsites. To meet this objective, periodic observations of the work taking place on a building construction project were conducted. During the observations, tens of hours of video recordings of workers conducting their traditional jobs/tasks were taken. After the completion of the work, an analysis of the two-mode networks for the worker and design element interactions using the social network analysis method was conducted. Two design element cases were analyzed, the concrete slab and steel beam components of the structure. The analysis shows that the workers are highly connected when considering the worker-design element interaction. To some extent, this result confirms the impact of design elements on the risk level of a worker. In addition to investigating the risk results for different trades on the jobsite, this study is unique in that it is the first in construction safety research to develop and analyze two-mode networks on top of video observations. The construction community can benefit from this study by extending current knowledge of the interactions that might lead to indirect risks, and then planning the work in a way that prevents and/or controls these interactions.
