Abstract

Urban Water Supply and Sanitation Sector Project (UWSSSP) have played a vital role in improving access to safe drinking water and sanitation services in various areas of Nepal. However, many projects under UWSSSP experienced delays that have affected project cost, project timeline, overall construction quality, and ultimately service delivery. This study aims to identify and rank the causes and effects of delays in UWSSSP in the hilly region of Nepal and to recommend strategies to minimize significant delay in water supply projects. The causes and effects of delay were identified based on literature review and study of contract administration documents of UWSSSP. A structured questionnaire survey was conducted among the experts from clients, consultants, and contractors involved in UWSSSP and collected data were analyzed using the Triangular Fuzzy Analytic Hierarchy Process (FAHP) and thematic analysis. The integrated analysis reflected that force majeure events, socio-political issues, inadequate site investigation, delays in document approval, and poor communication among stakeholders were the highly significant causes of delay. Regarding the impacts of delays in UWSSSP, cost overrun, time overrun, and poor construction quality were found to be most significant. Similarly, the analysis of mitigation strategies highlighted the importance of project readiness, site-specific planning and design, stakeholder participation, and effective contract administration in minimizing significant delays in water supply projects. This study recommends implementing a "Ready-to-Construct" Gateway Policy before bidding or contract award to minimize significant delays and ensure smooth implementation of water supply projects. The findings of this study are believed to provide valuable insights for policymakers, project managers, consultants, and contractors to improve project performance and minimize delays in future water supply projects in Nepal.
