Improving the Assessment of Economic Foreign Exchange Exposure in Public–Private Partnership Infrastructure Projects
(American Society of Civil Engineers, 2012)Unexpected foreign exchange (FX) rate changes represent an important risk factor, especially in public-private partnership (PPP) infrastructure projects in developing countries. The risk exists because PPP projects typically ... -
Evaluation of On-Site Fuel Use and Emissions over the Duration of a Commercial Building Project
(American Society of Civil Engineers, 2012)Commercial construction operations are heavy users of nonroad equipment and diesel engines. These engines are large contributors of carbon dioxide ( -
Interface Network Models for Complex Urban Infrastructure Systems
(American Society of Civil Engineers, 2011)The reliability assessment of infrastructure systems providing power, natural gas, and potable water is an integral part of societal preparedness to unforeseen hazards. The topological properties of interface networks ... -
Preliminary Comparative Life-Cycle Impacts of Streetlight Technology
(American Society of Civil Engineers, 2011)As part of a streetlight-retrofitting project in Pittsburgh, this study performed a cradle-to-grave life-cycle assessment of four lighting technologies: the widespread high-pressure sodium and metal halide lights, and the ... -
Modeling Geospatial Interdependence for Integrated Municipal Infrastructure
(American Society of Civil Engineers, 2012)This paper presents a computational model for establishing the interdependence among municipal assets. To create a multiyear plan for the maintenance of municipal asset networks, it is necessary to know the interdependencies ... -
Critical Assessment Indicators for Measuring Benefits of Rural Infrastructure Investment in China
(American Society of Civil Engineers, 2011)Rural infrastructure is of vital importance for agricultural growth, economic development, and poverty alleviation, particularly in developing countries such as China. In line with the implementation of a Coordinated ... -
Bilevel Optimization for Integrated Shelter Location Analysis and Transportation Planning for Hurricane Events
(American Society of Civil Engineers, 2011)Responding to hurricanes is an exceedingly complex task, the effectiveness of which can significantly influence the final effects of a hurricane. Despite a lot of progress, recent events and unchecked population growth in ... -
Nondestructive Assessment of Axial Load–Deflection Behavior of Drilled Shafts for a Suspension Bridge
(American Society of Civil Engineers, 2012)The new Río Cuarto Bridge, currently under construction in the Province of Córdoba, Argentina, consists of a 110-m long, cable-stayed main span with a prestressed concrete deck, steel pylons, and two 50-m–long side spans ... -
Transformation of Infrastructures: Sector Characteristics and Implications for Fundamental Change
(American Society of Civil Engineers, 2011)Infrastructure sectors such as energy or water supply, sanitation, or telecommunications provide us with services that are essential for modern life and for industrialized societies. In this article, we explore some of the ... -
Framework for Computing a Performance Index for Urban Infrastructure Systems Using a Fuzzy Set Approach
(American Society of Civil Engineers, 2011)This paper presents a framework for characterizing, analyzing, and computing the performance of urban infrastructure systems. The framework is based on a systems approach and consists of performance indicators classified ... -
Discussion of “Probability of Failure Analysis due to Internal Corrosion in Cast-Iron Pipes” by Hamid Yamini and Barbara J. Lence
(American Society of Civil Engineers, 2012) -
Exploratory State-Level Empirical Assessment of Pavement Performance
(American Society of Civil Engineers, 2011)This study uses aggregate state-level data from 1999 to 2006 in the United States to examine the relationships among pavement performance (pavement roughness) and preservation expenditure, dominant surface geology, and ... -
Rapid Bridge Deck Condition Assessment Using Three-Dimensional Visualization of Impact Echo Data
(American Society of Civil Engineers, 2012)Ultrasonic seismic methods can be used in the condition assessment of bridge decks by evaluating changes in material characteristics and detecting the development of defects and zones of deterioration. The impact-echo ... -
Reliability Evaluation of Corroding Pipelines Considering Multiple Failure Modes and Time-Dependent Internal Pressure
(American Society of Civil Engineers, 2011)A methodology is developed to evaluate the annual failure probabilities of a pressurized pipeline at an active metal-loss corrosion defect. The methodology takes into account three different failure modes at the defect ... -
Supply-Driven Dynamic Inoperability Input-Output Price Model for Interdependent Infrastructure Systems
(American Society of Civil Engineers, 2011)A supply driven dynamic input-output inoperability model (SDIIM), which extends the classical dynamic inoperability input-output model (DIIM), is described in this paper. The classical DIIM was developed to help understand ... -
Parametric Model for Conceptual Cost Estimation of Concrete Bridge Foundations
(American Society of Civil Engineers, 2011)Motorway bridges constitute a major part of modern transportation infrastructure networks. Interestingly, although foundations substantially influence the bridge construction cost, few studies have focused on predesign ... -
