Abstract
Developments in safety management on large UK construction sites have seen a paradigm shift from enforcement-based systems to safety-culture programmes, which seek to engage with the workforce to create fully cooperative and safety-conscious sites. Founded in social constructionism, recent research sought out the master discourses of safety on large UK construction sites through the examination of safety signage, talk around safety and safety documentation. Two of the most prominent discourses of safety on sites were found to be safety as enforcement and safety as engagement, reflecting the change in safety management strategies. These discourses were found to be interrelated in their constructions of safety, yet also varied in their associations with practice, responsibility, social interactions and the management hierarchy of the sites. These findings develop the current understanding of safety found on sites, with relation to the hierarchical structures of safety management and the discourses of enforcement and engagement in practice. The findings have significance for the safety practices of large UK contractors in developing and improving their safety-culture programmes, as well as suggesting potential new directions in the academic research of safety in construction.
