This study provides evidence of a decline in suicide rates among Australian construction workers over the last two decades; this decline may be attributable to the combined effects of population-wide, male-specific, and sector-specific suicide prevention efforts over this same period, suggesting that the continuation or expansion of such efforts may lead to further declines.

This research aims to identify the most suitable sustainable construction method for high-rise building construction in Australia; results show that the off-site construction method and robotic construction technique significantly improve the construction performance of high-rise construction in Australia.

Sustainable building design should consider durability, affordability, resource conservation, intra and intergenerational social equity aspects, and stakeholder’s perspective throughout its service life; this research has applied life cycle sustainability assessment (LCSA) framework to estimate the sustainability performance in terms of a single score, and to identify avenues for sustainability improvement strategies of buildings.
