Abstract: Occupational safety risk (OSR) assessment in construction projects is a complex process. Dynamic OSR assessment, according to the construction schedule, is uncommon because it is challenging to do despite its potential value to managers. This article proposes a new dynamic OSR modelling framework, based on Network Theory. Its originality is (1) exploring the risk relationships among workers by combining construction activities done by different trades and the interactions among risk factors causing safety accidents; (2) developing a dynamic risk network across construction stages for assessing construction workers' OSR prevention priorities. The application is utilised in a tunnel construction project in China.
