Quantifying and Benchmarking the Project Delivery Performance of Public-Private-Partnership (PPP) Transportation Projects in the U.S.

The use of public-private-partnerships (PPP) has increased in the U.S. since the early 1990s. Infrastructure design and construction projects have seen significant variations in costs and schedules under traditional project delivery systems, and therefore this report aims to quantify the cost and schedule performance of recently completed PPP projects in the U.S. transportation sector, and compare them to their non-PPP counterparts. The hypothesis of the study is that PPP projects will show superior performance, mainly due to the integration of major stakeholders and sharing of information throughout the project lifecycle. The authors collected and verified data through professional datasets and structured interviews with key projects constituents. The report presents results stemming from 25 completed PPP transportation projects. All projects in the dataset were completed between 1995 and 2013 with project costs ranging from $18 million to $2.1 billion, and totaling about $14 billion. Results of the analysis show an average cost growth of 3.22% and an average schedule growth of 1.2%, which highlight superior performance when compared to traditional design-bid-build delivery. This research fills a gap of knowledge on PPP project performance in the U.S. transportation sector. It also compares the results to those of projects delivered using the traditional method and of previous research efforts studying the international PPP market.
