Appraising critical success factors in sustainable housing projects: A comparative study of PPP modalities in Saudi Arabia

Abstract

This study examines the critical success factors (CSFs) crucial for the effective deployment of public-private partnership (PPP) models in sustainable housing projects in the Kingdom of Saudi Arabia (KSA), underpinning the nation's Vision 2030. Through a robust methodology that incorporates a profound literature review, structured interviews, and a survey involving key stakeholders, the study prioritizes fourteen significant CSFs integral to PPP efficacy. Employing Analytical Hierarchy Process analysis, key outcomes underscore the paramount importance of technical aspects with an emphasis on sustainability, tailoring risk-sharing and allocation to encompass green technologies and eco-friendly practices, and economic stability in the light of long-term environmental sustainability in fostering successful sustainable housing projects. Notably, the Build-Operate-Transfer (BOT) model is categorized as the most effective PPP modality, attaining a mean importance score of 4.07. This model is contrasted with other modalities such as Design-Build-Operate (DBO) and Build-Own-Lease-Transfer (BOLT), which scored lower in effectiveness. This comprehensive evaluation provides crucial insights for policymakers and practitioners, emphasizing the strategic selection of PPP modalities and the prioritization of CSFs to enhance the sustainability and effectiveness of housing projects in KSA.
