Driving Gender Diversity in Construction: Mapping Exisiting Policies Through the Behavioral Change Wheel Framework

Achieving gender diversity in the construction industry remains a critical challenge despite global efforts to reduce workplace inequality. Women remain significantly underrepresented in technical, trade, and leadership roles, with the majority occupying clerical or administrative positions. This study systematically categorises existing gender diversity policies in the construction sector using the Behavioural Change Wheel (BCW) framework to identify gaps and opportunities for improvement. A systematic literature review was conducted using the PRISMA methodology, analysing peer-reviewed studies and reports published over the last 30 years. The identified policies were mapped to the BCW’s seven categories: communication/marketing, guidelines, legislation, regulation, fiscal measures, environmental/social planning, and service provision. Findings indicate that while policies address capability, opportunity, and motivation barriers, significant gaps remain in implementation and monitoring. Key areas requiring further development include transparent recruitment processes, flexible work arrangements, and targeted interventions to mitigate unconscious bias and workplace harassment. The lack of real-world validation and actionable implementation strategies limits the practical impact of existing policies. This study provides a structured, evidence-based categorisation for policymakers, industry leaders, and advocacy groups to design targeted interventions that foster inclusivity. By aligning policies with behavioural change strategies, the research contributes to closing the gender diversity gap in construction, promoting workforce equity, and driving cultural transformation within the industry.
