Type: conference-paper
Study design: Observational Study
Abstract: This paper addresses a critical gap in the supply chain risk management by investigating risks specific to Hybrid Annuity Model (HAM, a public-private partnership framework) infrastructure projects in India, marking the first dedicated analysis of HAM-related supply chain vulnerabilities in this context. A survey questionnaire was designed considering different factors that affect time and cost of road construction projects. The respondents targeted were road construction industry professionals, including project managers and engineers, to collect insights on the impact of identified risks. A total of 230 responses were collected and analyzed using Principal Component Analysis (PCA) to reveal underlying relationships among the factors. The results indicate eight significant risk components - (i) supply-chain and resource-availability risk, (ii) organizational and management risk, (iii) regulatory, legal and funding risk, (iv) technical and operational quality risk, (v) safety and environmental risk, (vi) economic and geotechnical uncertainty risk, (vii) technological and process execution risk, and (viii) scope management and variation risk. The findings underscore the necessity for effective risk management strategies to improve project performance and pave the way for future research on leveraging the HAM model to address these challenges. Overall, this research enhances the understanding of the complexities within the supply chain of road construction projects in India and emphasizes the importance of integrated risk management practices to address these issues effectively.
