Exploring Spatial Relationship between Roadway Safety and Wet Condition Risk Factors Based on Systemic Safety Analysis Approach
(American Society of Civil Engineers, 2018)This study applies spatial analysis to investigate the relationship between crashes, wet road conditions, and physical roadway variables. Wet roadway and flood risk factors are not included in the data-driven systemic ... -
Cost Profiling of Water Infrastructure Projects
(American Society of Civil Engineers, 2018)The expected final budgeted costs of infrastructure assets are often exceeded during project delivery. Being able to determine the likelihood of changes to the final budget can enable clients to implement strategies to ... -
Evaluating the Resilience of Sustainable Neighborhoods by Exposing LEED Neighborhoods to Future Risks
(American Society of Civil Engineers, 2018)This paper examines Leadership in Energy and Environmental Design for Neighborhood Development (LEED-ND), a sustainability rating system for neighborhoods, to determine the extent to which its supported actions also ... -
Structural Design and Lifecycle Assessment of Heated Pavement Using Conductive Asphalt
(American Society of Civil Engineers, 2018)Snow and ice on pavements would affect the mobility and safety of motorists unfavorably. As a cost-effective and pollution-free solution, this study proposes a heated pavement system using multifunctional conductive asphalt ... -
Damage Propagation from Component Level to System Level in the Electricity Sector
(American Society of Civil Engineers, 2018)In the aftermath of an earthquake, the electric power supply system may have a reduced ability to maintain its intended function, leading to service disruptions of other interdependent facilities until the electricity ... -
Residual Value Risks of Highway Pavements in Public–Private Partnerships
(American Society of Civil Engineers, 2018)Residual value risk of an infrastructure asset under public–private partnerships (P3s) refers to the risk that on expiry or termination of the P3 contract, the asset does not have the value that the sponsoring public ... -
Facility Management Process of an Office Building
(American Society of Civil Engineers, 2018)Interest in the effective facility management (FM) of office buildings is rapidly increasing because of a significant demand for increased reliability and performance of facilities to enhance employee productivity. In this ... -
Identification of Critical Pipes for Proactive Resource-Constrained Seismic Rehabilitation of Water Pipe Networks
(American Society of Civil Engineers, 2018)Utility managers in charge of water pipe networks that are exposed to high seismicity make difficult decisions regarding the allocation of a limited rehabilitation budget to be most effective in enhancing a network’s ... -
Real-Time Energy Audit of Built Environments: Simultaneous Localization and Thermal Mapping
(American Society of Civil Engineers, 2018)Leveraging thermography for managing built environments has become prevalent as a robust tool for detecting, analyzing, and reporting their performance in a nondestructive manner. Despite many documented benefits of ... -
Prioritizing Investments in Improving Flood Resilience and Reliability of Wastewater Treatment Infrastructure
(American Society of Civil Engineers, 2018)Infrastructures are important facilities in urban areas servicing societies. Failure of these systems could pose a significant threat to the public. Increasing the infrastructure’s reliability is one way to ensure that ... -
Options Framework and Valuation of Highway Infrastructure under Real and Financial Uncertainties
(American Society of Civil Engineers, 2018)This study builds and applies a framework that addresses the twin uncertainties of traffic flow and interest rates in build-operate-transfer (BOT) projects. Existing valuation methods address traffic flow estimations using ... -
Adaptive Capacity Planning Formulation for Infrastructure Networks
(American Society of Civil Engineers, 2018)This research investigates the adaptive capacity enhancement problem of network systems and proposes a framework for allocating limited resources during the response phase in the aftermath of a disruptive event. The proposed ... -
Dynamic Modulus Model of Hot Mix Asphalt: Statistical Analysis Using Joint Estimation and Mixed Effects
(American Society of Civil Engineers, 2018)This paper presents the specification and estimation of a model for hot-mix asphalt dynamic modulus |E*| using 6,821 observations of 265 specimens from three different data sets containing variables in common such as air ... -
Risk-Informed Bridge Ranking at Project and Network Levels
(American Society of Civil Engineers, 2018)A novel method is proposed to rank bridges for maintenance priorities based on the risk posed by structural deterioration. The proposed method integrates structural reliability analysis, public datasets, and traffic flow ... -
Decision-Making Framework for Holistic Sustainable Disaster Recovery: Agent-Based Approach for Decreasing Vulnerabilities of the Associated Communities
(American Society of Civil Engineers, 2018)Sustainable disaster recovery involves not merely the restoration of the physical built environment, but also meeting the needs of the impacted stakeholders and decreasing the vulnerability of the host community to future ... -
Frequency Wave Number–Domain Analysis of Air-Coupled Impact-Echo Tests in Concrete Slab1
(American Society of Civil Engineers, 2018)An air-coupled (also known as noncontact or contactless) sensing technique in the impact-echo method has been developed and its practical application to the field has been significantly improved. However, unlike the flexural ... -
Government Cost of Extending Concession Term Rights
(American Society of Civil Engineers, 2018)A widespread practice used in concession-based public private–partnerships (PPPs) arrangements consists of granting the concessionaire the right, under certain circumstances, to extend the concession term under a ... -
Review of Public–Private Partnership Literature from a Project Lifecycle Perspective
(American Society of Civil Engineers, 2018)The process of developing a public–private partnership (PPP) is complex and dynamic throughout the project’s life cycle of project identification, preparation, procurement, implementation, transfer, and posttransfer phases. ... -
Regional Infrastructures as Complex Systems of Systems: Shared-State Model for Regional Resilience
(American Society of Civil Engineers, 2018)Present modeling and risk management for resilience of interdependent and interconnected (I-I) physical and cyber-physical infrastructure systems of systems (SoS) often rely on the same risk functions, models, and algorithms ... -
Managing for Change: Integrating Functionality, Resiliency, and Sustainability for Stormwater Infrastructure Assessment
