System Dynamics Models for the Valuation of Real Options in P3 Concession Project Agreements
(American Society of Civil Engineers, 2018)Public-private partnerships (P3) are increasingly being pursued for infrastructure procurement because of their ability to alleviate pressure on government budgets, promote innovation, and implement new technologies. These ... -
Diversion Ahead: Modeling the Factors Driving Diversion Airport Choice
(American Society of Civil Engineers, 2018)When airlines and air traffic controllers in the United States decide how to divert flights en route to an airport that is experiencing a complete or partial outage, their decisions determine the resiliency of the aviation ... -
Community Detection in Action: Identification of Critical Elements in Infrastructure Networks
(American Society of Civil Engineers, 2018)Modern infrastructure systems form complex networks that are organized hierarchically in communities of tightly integrated elements. This paper presents three new community-based metrics to identify the critical elements ... -
Critical Risk Factors of Transnational Public–Private Partnership Projects: Literature Review
(American Society of Civil Engineers, 2018)The importance of transnational public–private partnership (TPPP) has accelerated over the last decade, and the critical risk factors (CRFs) of TPPP have gained increasing attention from both researchers and practitioners. ... -
Use of Unmanned Aerial Vehicle Photogrammetry to Obtain Topographical Information to Improve Bridge Risk Assessment
(American Society of Civil Engineers, 2018)Bridges, as all objects in road networks, are built to provide a specified level of service over a specified time period. This level of service ensures that acceptable levels of health, safety, and prosperity of society ... -
Power Infrastructure Sector Reforms, Power Generation, and Private Investments: Case Study from Ghana’s Power Sector
(American Society of Civil Engineers, 2018)This paper assesses the impact of power infrastructure investments in the developing economy of Ghana following sector restructure and reform and develops a forecasting model for predicting the future trend in electricity ... -
Postearthquake Decision Making on Sewer Recovery and the Roles of Damage and Repair Data: Case Study of Christchurch, New Zealand
(American Society of Civil Engineers, 2018)Decision making on the reinstatement of the Christchurch sewer system after the Canterbury (New Zealand) earthquake sequence in 21–211 relied strongly on damage data, in particular closed circuit television (CCTV). This ... -
Performance Assessment of a Water Supply System under the Impact of Climate Change and Droughts: Case Study of the Washington Metropolitan Area
(American Society of Civil Engineers, 2018)Fresh water demand is rising due to factors such as population growth, economic development, and land use changes. At the same time, climate change is rendering the water supply even more uncertain for the future. Due to ... -
Performance Evaluation of Water Distribution Systems and Asset Management
(American Society of Civil Engineers, 2018)Water distribution systems (WDS) are among the most critical civil infrastructure systems. A reliable and safe water supply is essential for the prosperity and continued well-being of society. Hence, adequate maintenance, ... -
Parameterized Fragility Assessment of Bridges Subjected to Hurricane Events Using Metamodels and Multiple Environmental Parameters
(American Society of Civil Engineers, 2018)A vulnerability assessment of bridges subjected to hurricane events is beneficial to policy makers prioritizing their critical assets for inspection, maintenance, and retrofit. The proposed parameterized fragility assessment ... -
Characterizing Permeable-Pavement System Water Flow Using the Cumulative Hydrograph Model Approach
(American Society of Civil Engineers, 2018)Increased runoff rates on paved surfaces pose safety risks to city residents. Therefore, research on permeable pavement, with the goal of reducing runoff, has been growing in popularity. This study uses experimental and ... -
Closure to “Comparison of Three Retaining Wall Condition Assessment Rating Systems” by Mohammed A. Gabr, William Rasdorf, Daniel J. Findley, Cedrick J. Butler, and Steven A. Bert

Network-Level Pavement Structural Evaluation
(American Society of Civil Engineers, 2018)This paper addresses the use of traffic-speed deflection devices for the structural evaluation of pavements at the network level as part of an effort funded by the Federal Highway Administration. Highlights from three major ... -
What Cannot Be Cured Must Be Endured: Understanding Bridge Systems as Institutional Relics
(American Society of Civil Engineers, 2018)Why do outdated bridges persist even when there are capable engineering management systems to remediate such systems and their associated costs? This study explores the institutional constraints that inhibit bridge managers ... -
Sharing Risks in Toll Motorway Concessions: Subsidies as Real Options on Traffic Volume
(American Society of Civil Engineers, 2018)Public Administrations need to raise private financial resources to provide for infrastructures. These projects are, however, perceived by investors as risky, so it is necessary to look for risk-sharing mechanisms that ... -
Bridge Quality Appraisal Methodology: Application in a Reinforced Concrete Overpass Roadway Bridge
(American Society of Civil Engineers, 2018)Bridge quality control plans and asset management systems are often integrated in collective frameworks used by authorities nationally and internationally. Similarities among these frameworks include the utilization of ... -
Does Pavement Degradation Follow a Random Walk with Drift? Evidence from Variance Ratio Tests for Pavement Roughness
(American Society of Civil Engineers, 2018)Planning agencies increasingly use pavement management systems (PMS) to determine an optimal preservation strategy for their roadway assets. To develop cost-effective resource allocation policies, it is important that a ... -
Homeowner Decisions to Retrofit to Reduce Hurricane-Induced Wind and Flood Damage
(American Society of Civil Engineers, 2018)Even as new incentive programs emerge to encourage homeowners to strengthen their homes so as to reduce the risk of damage in extreme events, little is known about how homeowners make such decisions. In this paper, we ... -
