Structural equation model of construction safety culture

Abstract

PurposeThis paper sets out to describe the development and empirical testing of a structural equation model of construction safety culture. A key contribution of the model is providing insights into the interactions among safety culture enablers, and the relation between those enablers (what the organisation is doing) and safety culture goals (what the organisation aims to achieve) in the context of the Thai construction industry.Design/methodology/approachBased on the internationally recognised EFQM Excellence model, this paper empirically examines the interactions and causal relationships between five enablers (i.e. Leadership, Policy and strategy, People, Partnerships and resources and Processes) and safety outcome (i.e. Goals). The paper utilises the structural equation modelling technique to test the hypothesised positive inter‐relationships between the enablers and goals. A questionnaire survey was administered to a sample of construction contracting organisations operating in Thailand to elicit opinions on the different attributes in the context of their current safety practices and performance.FindingsSupported by empirical evidence, this study established that firstly, the Leadership enabler directly influences the implementation of Policy and Strategy, however, its effect on Partnerships and Resources appears to be an indirect one; secondly, Partnerships and Resources was found to indirectly affect Processes through Policy and Strategy, which likewise appears to be indirectly influenced by the People enabler.Originality/valueThis study provides a greater understanding of the interactions between the key elements of safety culture (enablers and goals), and among the enablers themselves.
