Factors Affecting Life-Cycle Cost Analysis of RC Structures in Chloride Contaminated Environments
(American Society of Civil Engineers, 2007)Corrosion of reinforcing steel is the main course of deterioration of reinforced concrete (RC) structures in chloride contaminated environments. Various measures can be employed to protect RC structures against corrosion ... -
Quantifying Effectiveness of Cathodic Protection in Water Mains: Case Studies
(American Society of Civil Engineers, 2007)Cathodic protection is a viable measure to extend the residual life of water mains and thus defer capital investments in their rehabilitation and renewal. The effectiveness of cathodic protection varies with the unique set ... -
Costs and Benefits of Home-Based Telecommuting: A Monte Carlo Simulation Model Incorporating Telecommuter, Employer, and Public Sector Perspectives
(American Society of Civil Engineers, 2007)This paper reviews and utilizes the current body of telecommuting related research to study the costs and benefits of home-based telecommuting. Monte Carlo simulation methods were utilized to help account for costs or ... -
Evaluation of Trenchless Technology Methods for Municipal Infrastructure System
(American Society of Civil Engineers, 2007)The deterioration of municipal underground infrastructure systems and a growing demand for utility services have increased the necessity for more efficient installation, inspection, repair, rehabilitation, and replacement ... -
Pavement Resurfacing Planning for Highway Networks: Parametric Policy Iteration Approach
(American Society of Civil Engineers, 2007)This paper presents a modeling framework for planning pavement resurfacing activities on highway networks in the case of continuous pavement state, discrete time, and infinite horizon. Optimal resurfacing policies that ... -
Prediction of Water Pipe Asset Life Using Neural Networks
(American Society of Civil Engineers, 2007)This paper describes investigations into a development of a new application of neural networks (NN) for prediction of pipeline failure. Results show higher correlations with recorded data when compared with the two existing ... -
Approach to Determine Extent and Depth of Highway Flooding
(American Society of Civil Engineers, 2007)Flooding and flash flooding pose serious infrastructure hazards to human populations in many parts of the world. During a flood, it is critical to identify road segments that are flooded so that rescue and response routes ... -
Knowledge-Based Condition Survey Inspection Concepts
(American Society of Civil Engineers, 2007)The U.S. Army’s Engineer Research and Development Center—Construction Engineering Research Laboratory has developed a “knowledge-based” approach to planning and conducting routine facility inspections. Rather than simply ... -
Condition Assessment of Water Distribution Pipes
(American Society of Civil Engineers, 2006)With average pipe replacement rates in the United States at about once in -
Recent Progress in the Modeling of Corrosion of Structural Steel Immersed in Seawaters
(American Society of Civil Engineers, 2006)For coastal infrastructure the long-term durability of new steel structures and the remaining life of existing steel structures is of central interest to their proper maintenance and asset management. This is particularly ... -
Repeated Measurement Data Analysis in Pavement Deterioration Modeling
(American Society of Civil Engineers, 2006)This paper considers the nature of repeated measurement data under the framework of the mixed-effects approach with an extension of an empirical nonlinear model of rutting progression on asphalt concrete pavements. The ... -
Using Disturbance Data to Assess Vulnerability of Electric Power Delivery Systems
(American Society of Civil Engineers, 2006)In this paper we discuss how to assess the vulnerability of electric power delivery systems with the help of standard power system performance indices. In two case studies, statistical analyses of disturbance data from ... -
Prioritizing Sanitary Sewers for Rehabilitation Using Least-Cost Classifiers
(American Society of Civil Engineers, 2006)Sewer rehabilitation is one control option for relieving wet-weather sanitary sewer overflows by reducing rainfall dependent inflow and infiltration. The prioritization of rehabilitation activities is based on the physical ... -
Methodology for Locating Monitoring Stations to Detect Contamination in Potable Water Distribution Systems
(American Society of Civil Engineers, 2006)The requirements to protect public water systems from external contamination have expanded in the years following September 11, 2001. The areal extent and nonlinear nature of fluid demand and movement in the distribution ... -
Optimal Scheduling of Replacement and Rehabilitation of Water Distribution Systems
(American Society of Civil Engineers, 2006)Many municipal water distribution systems across North America are reaching or have exceeded their design lives and, therefore, require extensive upgrading through rehabilitation and/or replacement. However, these needs ... -
Adaptive Optimization and Systematic Probing of Infrastructure System Maintenance Policies under Model Uncertainty
(American Society of Civil Engineers, 2006)We present an application of systematic probing for selecting optimal maintenance, repair, and reconstruction (MR&R) policies for systems of infrastructure facilities under model uncertainty. We use an open-loop feedback ... -
Impacts of the 2001 World Trade Center Attack on New York City Critical Infrastructures
(American Society of Civil Engineers, 2006)This study investigates impacts of the 2001 World Trade Center attack on critical infrastructure systems in the New York City metropolitan area. Of particular interest are the physical or logical connections—also known as ... -
Impact of Quality on Building Costs
(American Society of Civil Engineers, 2006)Quality of design, material used and workmanship, affects the future operating, maintenance and rehabilitation costs of infrastructure; however, the extent to which quality affects these costs has never been explicitly ... -
