Abstract Build-Operate-Transfer (BOT) model of public-private partnerships (PPPs) are among the most popular infrastructure delivery models used by governments across the globe. Yet, concession agreements are criticized for being dispute prone. This study identifies a few areas where BOT projects are often challenged and proposes further interventions. Interviews with the private developers and the transactions advisory provided the necessary evidence for exploring the expectations of revising the BOT Concessions. The study found interventions that the private sector stakeholders suggest. These interventions span over the procurement, construction, and operation phases of the infrastructure delivery and are argued to build a rubber wall that can absorb the impacts of risk events. The suggested interventions would be helpful to policymakers to understand the prevailing challenges and expectations of the private sector developers. Future BOT concessions can be less dispute prone by deliberating and effectuating a mutually beneficial bargaining power. This study did not focus on the public sector perspective and their challenges for not considering these alternatives. Future studies need to expand to make the results more amicable and implementable. BOT concession model is popular but ever evolving. This study challenges the status quo by identifying a few challenges to be considered for increasing its effectiveness.
