System dynamics modelling of construction safety culture

Abstract

Purpose

This paper forms part of an ongoing research project being undertaken by the authors into construction safety culture. The paper aims to investigate the interactions among five key enablers of construction safety culture, as well as the potential impact of each enabler on organisational safety goals over a period of time.

Design/methodology/approach

Using system dynamics modelling, the paper reports on the development of a causal model simulating the interactions among safety culture enablers. The model is developed based on the logical assumption that, by improving the enablers, there will be an inevitable safety performance improvement. An index is also proposed and used as an indicator for assessing the maturity level of safety culture.

Findings

The paper presents and reports on simulation results which reveal that an organisation with ad‐hoc safety implementation (starting at a basic level of safety culture maturity) should primarily focus on enhancing leadership attributes, in the context of safety, to rapidly and successfully progress through to higher maturity levels in the future.

Practical implications

The use of system dynamic modelling, with the developed index, will help organisations to plan the most effective safety implementation process to achieve their safety goals within a planned time frame.

Originality/value

The use of modelling, with the developed index, will help organisations to plan the most effective safety implementation process to achieve their safety goals within a planned time frame.
