Abstract: This study develops a framework for selecting an appropriate procurement option to accelerate sustainable infrastructural development in Delta State, Nigeria, with emphasis on Public–Private Partnerships (PPPs) as an alternative to traditional procurement models. The research adopted a mixed-method approach, engaging 30 purposively selected construction professionals, including architects, engineers, quantity surveyors, builders, land surveyors, and town planners. Quantitative data were analyzed using the Relative Importance Index (RII), while qualitative insights were thematically interpreted. Findings reveal that inadequate funding, bureaucratic delays, and suboptimal project quality hinder infrastructure delivery under conventional procurement systems. Drawing lessons from the Lagos State PPP model, a tailored framework was proposed for Delta State, outlining institutional roles, project selection criteria, and operational procedures through the Office of Public–Private Partnership Infrastructure Development Agency (OPPPIDA). The framework aims to enhance efficiency, cost-effectiveness, and transparency in project delivery, aligning with Sustainable Development Goal (SDG) 9. The study recommends adopting this PPP model, strengthening institutional capacity, and prioritizing high-impact projects in housing, transport, and water supply to bridge infrastructure gaps sustainably.
