Migrant construction workers often endure precarious living conditions in temporary labor colonies, lacking adequate infrastructure, basic services, and climate resilience. Climate change further exacerbates these challenges, posing significant risks to urban development and vulnerable populations. This study examines the critical factors that supply-side stakeholders must integrate to enhance livability and climate resilience in worksite housing for migrant labor colonies. Using a structured three-phase methodology—systematic literature review, focus group discussions, and the Fuzzy Delphi Method (FDM), this research identifies and prioritizes key housing indicators. The study initially identified 30 factors, later refined to 23 through expert validation. The most critical indicators include energy efficiency, ventilation, heat island mitigation, water supply, and policy support. These findings underscore the need for policy revisions, particularly within the Building and Other Construction Workers (BOCW) Act (1996), to incorporate climate-responsive housing standards. Although the study focuses on a specific urban context, its framework provides a scalable model for improving temporary housing conditions across diverse regions. The insights from this research offer actionable recommendations for urban planners, policymakers, and industry stakeholders to create sustainable, inclusive, and climate-resilient worksite accommodations for migrant workers.
