New submissions to the thesis/dissertation collections are added automatically as they are received from the Graduate School. Currently, the Graduate School deposits all theses and dissertations from a given semester after the official graduation date. This means that there may be up to a 4 month delay in the appearance of a give thesis/dissertation in DRUM

    EMERGENCE OF PRIVATE SECTOR IN PUBLIC-PRIVATE PARTNERSHIP PROJECTS AND ANALYSIS OF RELATIONSHIP BETWEEN STAKEHOLDER NETWORK CENTRALITY AND PROJECT PERFORMANCE
    (2019) Suwal, Sirish; Cui, Qingbin; Civil Engineering; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    Infrastructure and construction projects are large, complex, and arduous ventures involving various actors or stakeholders. However, taking decisions based on the individual attributes of stakeholders is insufficient. The emergence of the private sector in Public-Private Partnership (PPP) projects reveal the need to consider how multiple stakeholders in an inter-reliant network can impact the project’s performance. This research uses stakeholder and social network theories, and analyzes the centrality measures – total-degree, betweenness, closeness – of the key public and private entities against two project performance criteria: cost and schedule. Findings reveal that private sector becomes significantly more central in PPP projects, and there is a statistically significant correlation between private sector centrality measures and project schedule performance. In addition, the research reveals that the number of public agencies or sponsors involved in the project also plays a significant role in determining project performance

    DEVELOPING A FRAMEWORK FOR EX-POST VALUE FOR MONEY ANALYSIS IN PUBLIC PRIVATE PARTNERSHIP PROJECTS
    (2015) Ghorban, Amir; Cui, Qingbin; Civil Engineering; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    In recent years, Public Private Partnerships (PPPs) has emerged as a project delivery option for transportation projects in the US. This type of project delivery is generally a long term agreement between the public and private sectors for the purpose of delivering a project or service traditionally provided by the public sector. Some of the reasons for implementing PPPs are the ability to provide an overall lower life-cycle cost and to increase cost and schedule certainty. This is sometimes referred to as the ability to provide a better Value for Money, hence the use of Value for Money (VFM) analyses to compare overall financial impacts of PPP against those of a traditional delivery alternative. While the VFM analysis is considered as the best practice for selecting PPP approach, the primary challenge in conducting the analysis, however, is to validate the empirical results of these studies. Most of the previous studies have investigated ex-ante results and little has been done in regards to what can be considered ex-post studies. This study presents a framework for ex-post value for money analysis. Processes, data requirement, and algorithms are developed to ensure an ex-post assessment can be performed at various stages of PPP project development including commercial close, substantial completion, during operation and maintenance phase, and final acceptance. The Presidio Parkway project in San Francisco will be used as a case study to illustrate the method and procedure of ex-post VFM analysis framework.
