Efficiency Based Comparison of Project Delivery Methods

Abstract

Public Private Partnerships (PPP) are the future of infrastructure project delivery. Majority of the PPPs have been successful except a few over the past decade. The reasons for their failure are well documented by researchers. The misconceptions about PPPs make it increasingly difficult to pursue projects using PPP delivery system. One of the root causes of the misconceptions is from the ambiguities arising from qualitative data and assessments. To overcome this issue, efficiency-based comparison of project delivery methods utilizing Data Envelopment Analysis (DEA) for decision making is presented through this paper. Proposed approach uses qualitative ratings and harnesses the integral utility of the ratings obtained while conducting objective assessment of qualitative data. California’s Presidio Parkway Project is used for case study analysis and the data is varied to create three hypothetical scenarios to determine sensitivity of the model. Results from case study are consistent with actual project implementation and the sensitivity analyses result are found to be consistent.
