More than 30 years ago, early researchers examining gender representation in the American workforce called the construction industry a “non-traditional field” for working women. Despite the plethora of research and practice efforts over the intervening decades, the industry is still defined as a “non-traditional field” by contemporary measures. Researchers have proposed various tools for achieving the required social change to fix gender segregation in construction, including include patching hypothesised leaks in the education-to-work pipeline. This paper calls for a systematic inspection of the whole pipeline to investigate leaks in the education and career segments through root-cause analysis. International education and industry data from Australia, the USA, the UK and Brazil were comparatively analysed through a gendered lens. The findings shed light on the cross-sectorial approaches needed for systemic social change in the construction industry, which has historically been called “non-inclusive,” “unsafe for women,” a “white boys club,” “masculine” and “homogenous.”
