Abstract

Objectives. This research aims to develop, validate and implement health and safety performance metrics to evaluate the health and safety performance of sustainable building projects throughout their design and construction in Manitoba. Methods. Thirty-four metrics were developed following a detailed literature review and validated by expert judgement based on analytic soundness, practicality and predictability. Only 25 metrics satisfied these criteria, of which five were implemented via data collected on seven sustainable buildings and seven non-sustainable buildings. Results. The results showed that sustainable building projects had 12.7% higher recordable injuries rates than non-sustainable projects, although the difference was statistically insignificant. Findings from this research showed that for sustainable and non-sustainable building, PM 19 'The percentage of workers with unsafe behaviour based on conducted safety observations' had a statistically significant and strong negative correlation with PM 8 'The percentage of workers who attended safety meetings' and with PM 21 'The percentage of the total workdays in which safety meetings were held'. Conclusion. The findings of this research can be used by general contractors and safety practitioners looking to enact evidence-based guidance to manage safety proactively on site and improve health and safety performance of their sustainable building projects.
