Abstract

Purpose

This paper seeks to examine a hierarchical measurement model for occupational health and safety (OHS) performance developed for use in the Australian construction industry and tested over the life of one case study construction project. The model was intended to provide a more sensitive and informative measure of project OHS performance than traditional injury frequency rates.

Design/methodology/approach

Two measurement tools were tested. The tools, a monthly weighted safety index and a quarterly safety climate survey, were used to measure OHS performance and performance data are presented.

Findings

The data suggest convergent validity, indicated by consistent results between the two measures. Results also indicated that a combination of measurement techniques provides more comprehensive data pertaining to project OHS performance and enables the diagnosis of OHS issues that would be undetected with reliance exclusively on traditional measures, such as lost time injury frequency rates.

Research limitations/implications

The implications for future research lie in the demonstrated need to carefully evaluate the validity of the safety index and safety climate survey in future construction projects, and in the broader construction context. The results were limited to an evaluation of the measurement model in a single case study construction project and future testing is needed to determine the generalisability of the model.

Practical implications

The implications for practice are that multiple measures of OHS performance, including leading indicators and surveys of workers' attitudes and perceptions of project OHS, provide a more useful basis for the development of targeted OHS improvement strategies.

Originality/value

The paper develops a theoretical framework for the measurement of OHS using positive performance indicators and safety climate surveys. The evidence for convergent validity suggests that, in combination with traditional lost time injury rates, these measures provide a more robust method for the early detection and rectification of OHS issues in construction projects.
